At the time Sean and Chris did this job, the instructions available from Marlin Crawler left a lot to be desired. There was a lot of interpretation needed and seeking information from other sources to pull off this job. But now, thanks to Sean and Chris, people have a detailed tutorial to follow. What's interesting, is Marlin Crawler hasn't even taken advantage of this video series and linked it in the tech area of their website. We gave them a total gift and they don't use it. I respect the ingenuity Marlin Crawler brings to the Off-Road World, but I feel they leave a fair amount to be desired as a company to do business with. We've made some great industry partnerships over the 7+ years we've been running our channel. From what I can tell from my interaction with Marlin Crawler, they don't get or value what a RU-vid channel like ours can do for them. Those that get it, reap the benefits, because the companies we work with are always more on the receiving end of the relationship. It's always going to be lopsided and we're ok with that. As long as we know the company we are working with appreciates and respects what we do, then we're all good with them. There's many ways that appreciation and respect can be shown. We're not hard to please. Anyway, sorry for the novel. Happy Wrenching!
I hope somewhere there's a thanks for Sean and Chris as well. Marlin Crawler doesn't supply any real instructions on how to do this. Thanks to Chris and Sean, people now have an excellent tutorial to follow. Sort of hoping Marlin Crawler appreciates what Sean and Chris did for them too.
@@detectoraid5985 I see you changed your original message and added Tom Woods and Opt Off Road in the thanks. Still no thanks for Sean and Chris for all the work they did documenting the job and all the work Sean did editing it. You don't share that opinion of Marlin? Ok, please show me the detailed step by step instructions Marlin provides for their customers for their Taco Box Install? I'll wait........ Yeah, they don't exist. As for you comment about the adapter, that's pretty much a bullshit response. You act like it was Chris' fault he received the wrong adapter. That was all Marlin's fault. Marlin actually promised Chris a discount because of their mistake which delayed his project but they reneged on their promise and didn't give him a discount. You know what Dude, if you can't give credit where credit is due, don't comment on our videos anymore. Sean and Chris did an excellent job documenting this job. I agree with you giving thanks to Tom Woods and Opt Offroad because they actually sponsored this project. Marlin Crawler i guess gets credit for making the adapters. Other companies make them as well now so there's options people have. Hopefully Marlin will figure out how to improve on their production because they're consistently out of stock.
@@TimmyTheToolman Well, I do appreciate your video and whomever made it AND I agree with your comments about Marlin Crawler, INC. It would do for them to make their own instructions up for all the questions and inquiries they must get. It must be such a waste of time for them to address all the quandaries people have. I currently have my own adapter problems with them - they didn't ship one to interface with the transmission!
@@hebdomatical Marlin Crawler makes great products but they aren't the best at business. They can't seem to find a way to keep their products in stock and their customer service sometimes is severely lacking. You would think they would provide detailed install instructions for something they sell, but I guess not. Good thing there's RU-vidrs like us doing the work for them for free.
you make the best instructional videos I have seen. One thing I really like is you don't come out first thing showing how you make yourself a cup of got dam coffee!
Thanks for the compliment. What RU-vidr starts their videos with making a cup of coffee? People.get annoyed with how much I talk but I guess we're better than the guy who makes his viewers watch him coffee.
Such a killer mod. I'm a little jealous that you guys are 3rd gen guys. I'm a 4th gen guy. However I always enjoy your vids, there's a lot of overlap with the processes and just a few differences usually. As my truck gets older I get braver (more brave ??) at doing work on it, but I'll probably never have a reason do do serious mods like this. Maybe some day... Anyway, great work!!
Thanks for stopping by the comments. We appreciate you watching our vids and chiming in here. It was def a fair bit of work, but there are other mods which would help with wheeling like a front and rear locker and bigger tires should get you through any obstacles this rig could. A good driver mod always helps too!
Another great video, thanks for the time and effort gents! That jobs hard enough without all the camera work and editing...huge benefit to the 4rd gen community. Not to be greedy, but any plans for a video about the gas tank relocation?
Hey Ben, since the tank is completed and buttoned up, we were loosely planning to do the same thing and my truck. Not sure how quickly we will get to that so maybe an overview of the work on his might suffice for your needs? - Sean
@@TimmyTheToolman That would be great! Thanks and no rush. I am familiar with the Eim product and have followed most of the forum threads, but was just curious which direction you went with plumbing, wiring, pump, etc.
@@benriewer7817 he kept all the OEM stuff, bent the rod for the gas measure to fit in the shallower tank, and welded on the circular mounting fitting on top of the f-150 tank that was cut out of the original OEM tank
Oh no! Please don't leave us. How will we survive without you? Nobody else's opinion matters. We need you and only you Miguel. Please tell us how to be better RU-vidrs so you'll come back to us. And to a more serious response, I guess you're not really interested in learning how Sean and Chris finished the Dual Transfer Case mod. If you were truly interested, you wouldn't let a video intro deter you from watching it. By the way, the "Ghost Rider" shot is to show how slow the vehicle can move with both transfer cases engaged that you can literally jump out of the rig and let the rig crawl along for quite a long time and not hit anything because it's moving so slow. But oh well, Happy Trolling Miguel.
Hey guys, great video. As a manual transmission 3rd gen owner myself I am looking forward to getting to this stage! Main question is about the adjustable uppers. How tall of a lift is Chris running in the back? It seems like 12.5 inches would be a good starting point to get the pinion angle correct, I am running LC 8-wraps with about 4 1/2 inches of lift. Thx!
Chris’s lift is approximately the same as yours but everyone’s setup is different so you would just adjust accordingly to your needs. There isn’t an exact amount and Chris has been slightly adjusting the length of his uppers here and there as he drives it to dial it in more.
Not sure about the Tom Woods flanges. We didn't order them in the regular way since they sponsored the project. If you can't find them on their website, just give them a call. They aren't a company hard to get ahold of. If you call during business hours, someone will answer the phone and help you with your order. They are a solid company and I'm happy we established a relationship with them. Glad you found the video detailed. Chris and Sean did a really awesome job documenting this mod.
Perhaps the thinking has changed since my day, but FIPG can be problematic when you can't get at the joint on both sides to clean it after the part has been installed. One needs to clean off the excess, squeezed-out material, otherwise the hardened, excess beads can break off later on and plug oil galleys and just generally mess with stuff. Parts stuck together with silicone are usually pretty ugly and infer laziness, though it'll work when one can clean both sides after install, as was done here.
A transfer case doesn't use oil galleries to move gear oil to parts. A transfer case or manual transmission uses a splash method to carry the oil gear to gear and to other moving parts for proper lubrication. There is no oil pump. FIPG is used in certain situations on drivetrain components and quite often you can't see on both sides after the parts are assembled. Not everything has a metal, cork, or paper gasket. FIPG was used for many applications, like sealing engine oil or transmission pans, and is superior to a paper, cork or metal gasket because it can flow into imperfections in the metal that a regular gasket can't. Once any sealant has hardened, It's not going to break off unless something contacts it. I've cleaned off more than my fair share of sealant, and it doesn't come off that easy. Oil flowing past it is not enough to break off a chunk and have it plug an oil gallery. For the installation of valve covers on these Toyota engines, FIPG is used in conjunction with the rubber gasket to create a leak-free seal with the head. I've never heard of anyone worried about a piece of the gasket material breaking free and plugging an oil galley. What you do have to worry about is when you are doing something like a valve cover gasket job, and you're cleaning off old FIPG, that none of the old sealant you're scraping off ends up in any of the oil galleries. That's a legitimate concern. So, in closing, your comment that using sealant to put parts together is ugly and lazy is just plain ignorant. These vehicles came assembled from the factory with using FIPG for many applications. I think there was some bad information being given out back in your day.
I'm a retired aircraft mechanic and 'in my day' some of us dealt with failed engines in which silicone seal did play a part in that failure. The two I dealt with were a Baron and a 310, so the pilot was fortunately able to safely perform an emergency landing. The oil screens had silicone seal remnants in both of them. It was considered not quite illegal and certainly very gauche to use that stuff in aircraft engine overhauls, and engines I pulled apart with it were hard to disassemble and took a fair bit of extra effort to clean.. So times have changed. Upon re-reading, saying ugly and lazy was unnecessarily unkind and I deserve the ignorant shot back. I apologize for only that, and shall continue to use silicone seal only as a last-ditch sealing method where it is necessary and there is not any chance of engine contamination. Hylomar Blue or equivalent, which is 99% of assembly work, seals just as well, is far easier on disassembly, and I believe safer.
@wilnstevenson5957 I understand your position better now. Apology accepted. For many Toyota engine applications, the original way to seal two parts was sealant, not a physical gasket. There are now aftermarket options available for things like oil pan gaskets, but the preferred method is still using FIPG. I'm guessing for aviation applications, gaskets are available for everything. Take care.
As you perhaps now see, I am not ignorant, my critique was based in experience and facts. I accept criticism pretty well, but not when it is inaccurate. You were wrong to call me ignorant, just as I was wrong to call that sealing process lazy and ugly. All three are unnecessarily personal terms.
@@wilnstevenson5957 Well, your comment at that moment in time was ignorant in my opinion based off what I know about automotive engines, mainly Toyota engines. Now that I know where you are coming from working on aircraft engines, I understand better with your position. But still, not knowing these engines rely on FIPG for properly sealing of some parts is a level of ignorance you have with these engines. For the application of this video you are referring to, there is not a gasket to seal the transfer case to the transmission. That seal doesn't exist. This job is a modification to the normal drivetrain of these vehicles and Toyota never made a gasket for it nor did an aftermarket company make a gasket for it. Normally, no gear oil fills the cavity between the transfer case and transmission. When you install dual transfer cases, now that void does have gear oil running in it, and you need to seal that connection of the transfer case and transmission. The word ignorant can have negative implications towards the person it's directed towards, but a lot of times, it's just stating a fact that someone doesn't possess all the knowledge to make an informed statement or form an opinion. So, from my perspective, you were ignorant of some facts and that's why you made the comment you made. Make sense? I'm ignorant to a lot of subject matter. We all our. You obviously know a lot about aviation mechanics. I don't. But, I happen to know a fair amount about Toyota engines.
I think most guys with IFS carry at least one spare CV axle even without dual cases. All the guys I wheel with do. We've heard about RCV axles and their reputation of being strong. But, you have to give up your left nut to get a set. I just checked the price and it's a little over 2k. Another thing to consider is do you want the CV axle to be that strong? If the torque is too high and the CV axle doesn't break, maybe the front diff breaks and then you're really screwed. I can't speak for Chris but I'm gathering he's just going to carry 1, maybe 2 spares with him on wheeling trips.
Adding a second transfer case to your drivetrain won’t affect your gas mileage significantly, maybe .1 MPG if that. It adds a little extra weight but no more than a small child in the back seat. Armor, bigger tires, bumpers, roof rack and accessories etc are the main contributors to loosing MPG’s. Did you re-hear after stepping up to larger tires?
@@TimmyTheToolman no. That's something I am considering. What gears would you recommend for 60% road and 40% offroad/overlanding? Also how will I contact you guys for future build?
Chris ordered it a while back. How long, I don't know. You would think Marlin Crawler would get off their butt and start producing them since people obviously want them, but the way they operate really makes you scratch your head. They make great stuff, but their manufacturing leaves something to be desired. Why build something cool, advertise that product, and then not be able to fulfill orders? I don't get it.
You measure the distance from each driveshaft mounting flange. And the slip yolk compensates and adjusts the driveshaft shorter and longer as the vehicle goes through suspension cycling. - Sean
The Brodozer has been featured a couple times in videos but there will be more videos it's featured in. I really need to get it out on some technical trails and I'm going to make a point to get out there this next year.
I guess you're talking about the fuel tank mod. It helps if you use more words when asking a question. Luckily I remembered Sean and Chris mentioned this mod in the video. I'm not sure on the year. Contact Keith and ask him. He's the guy that makes the brackets for the mod. Here's his website: eimkeith.com/
Very cool, but god forbid you get stuck behind five guys who just got their dual cases and want to creep in the lowest gear for a trail that could be done in 2wd
@@TimmyTheToolman hopefully but, There are people out there who just have money to build and know nothing about off-roading. Start stock and gain skill, then mod, or should I say sicmod. Tim you are the absolute man and I can’t thank you enough for what you do for the community.
A pinion nut should NEVER be installed using an impact as it can damage the bearing race, or even the teeth of any gears or splines in the differential. There is a preload spec for differential pinion/bearings and it most definitely is not achieved precisely "with this impact pretty hard on this third setting" lol
You might have missed it but Chris got his rearend re-geared and the spacer is solid and not a crush spacer. So, he did no harm using an impact gun, because with the solid spacer, he can't change the preload of the bearing.
@@TimmyTheToolman You are correct, a solid spacer does not require a preload procedure as the nut will simply become tight and will not tighten further (with the risk of stripping threads). However, whether a solid spacer or a crush spacer is used is irrelevant to the harm caused by using an impact on the nut. What do you think is reacting the impact shock loading? Its the pinion gear teeth that are engaged with the ring gear teeth. Those teeth are effectively bouncing off the ring gear repeatedly at very high torque and can easily cause a fractured tooth or two. The pinion and ring gears are very stiff and made of very very hard steel alloys, making them very brittle and prone to fracture from impact shock loading. This is why chrome sockets will shatter when used with impact guns, because chrome vanadium alloy is relatively hard and brittle. Black impact sockets are softer and can take the abuse of impact shocks, hence they are made of chrome molybdenum alloy, which is softer than the typical chrome vanadium sockets. If your pinion and ring gears are made of chrome molybdenum (lol), then by all means use the impact gun.
@@hermanq5615 I personally wouldn't have used an impact to tighten that pinion nut, but I wasn't there and it's Chris' rig and he chose the impact. Could the impact cause damage to the gears? I don't know. If you're right and it's as dangerous as you say it is, I guess Chris got lucky because his 3rd member is just fine.
@@hermanq5615 I do agree with what your saying however that impact is pretty weak compared to most. In the video the socket used for tightening that specific nut was a chrome one lol. If it were a bigger impact with 1000ft lb of torque yes that would be bad.
It appears (starting at 6:40), if you can get the bell housing seal out you don't have to remove the bell housing or the c-clip, that "little dust cap cover thing" or bearing. I'll definitely work on that idea instead of all the extra work and sealing. Thanks for the video, sure is a lot more information than Marlin Crawler gives out. Installation sequence would be to install the 23-spline adapter through the remaining bearing and "that little dust cap thing"; then the spacer, then the seal. DONE. I think... I will try this to remove the seal: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wUKHphOOFo8.html Starting at 0:45 or 1:45 is better.
You do still need to remove the dust shield and bearing for the adapter to fit I believe, not sure if you can remove the bearing/dust cap from the back side but it’s worth a shot!
Timmy, I had the engine rebuild in my 2002 Tundra 3.4l v6 and I cannot get the “Drive Cycle” to set so it will pass the State emission test. I am getting drive cycle faults for Catalyst monitor and Evap monitor “Not Ready”. Help a brother out this is a F$&king nightmare my man. The TSB drive cycle info does not seem to help when I try to duplicate their procedure.
Interesting you should bring up issues completing the drive cycle. I had a P420 code pop up right before I was going to smog my 2000 4runner and now my registration is expired because the system isn't ready. I'm trying to avoid an expensive catalytic converter replacement, but it's not looking good after using some fuel additives to clean the cat. I've done research on this and the official drive cycle is nutty. It's pretty much impossible to complete unless you live in the country with long stretches of road with no stop signs or stop lights. I've never had an issue with passing smog on any vehicle until now. For you and me, something is keeping those monitors from passing and showing the system is ready to be tested. So, we're in the same boat and I don't have an answer for you unfortunately.
What would be the vehicle weight need to be to make a dual transfer case useful in your opinion? I guess we should have installed dual cases in a Tundra or a Ford F350 that couldn't even fit on most of the technical trails that would require dual cases. Your comment makes zero sense and it's clear you don't know what you're talking about. Weight has nothing to do with it. Dual transfer cases allows you more control when negotiating obstacles. It's especially beneficial for manual transmission rigs because you don't have to work the clutch over and over again. On a steep and gnarly grade, you can let the gears get you down in a controlled manner instead of riding the brakes. Do yourself a favor and research the subject matter before commenting on other videos.
