"Thanks a million for watching"! Thanks a million to you Kevin for posting. Love all this technical stuff, it also demonstrates a high level of technical competence within your business, 1st Class Sir, thank you.
I second that, Kevin is the MASTER of H. D. Motors, so much knowledge he shares with in these videos THANK YOU FOR TIME, EXPERT EXPERIENCE HERE!!!! KEVIN BAXTER👍✔️🤔😎
I was under the impression, the INA bearing was a "ball bearing." Now I see it's a roller bearing, but it's a flat roller, and not tapered, like a Tipcon Bearing. It's soooooo depressing, to spend so much money on something, that needs to be completely rebuilt, to "above stock standards," just to have a little peace of mind about the machine your ass is on. I enjoyed that Kevin. I like mechanic 'n on stuff. It's fun seeing someone who knows what they are doing 'most of the time!' Is this case you're working on, the same as my '04' 88ci TC? Being on '04,' does my 88ci TC have the tapered end connecting rods? I've never been inside it... Yet! If I have to crack open the cam chest, to inspect those chain tensioners, I might as well replace them... Even if I can't afford to change to gear driven cams, should I take out the cam plate and have the cam bearings changed on the primary side of the cam chest? Always more questions than time! Peace Kevin...
I have ALWAYS wanted to see the inside of a case with the flywheels, etc., and I have ALWAYS wanted to see how Timken bearings are installed. I had a Timken upgrade done on my twin-cam, but I had No Idea how it was done! These videos are really GREAT, and I only wish I lived closer to your shop. Well, at any rate, I'll get a chance to talk with you, in person, come August 16th!
Missed the premiere, I was out looking for sockets for my next repair, had to order them. Thanks for this, I know from experience that making video of the process slowed you down and I'm looking forward to the rest of this series. I'm going to send you a list of parts for quote once I get my bike torn down, want to wait until it is all apart so I get everything I need at once. This bike always produces a bunch of extra jobs when I do any work on it.
Kevin, you're quite the diplomat. If I didn't know any better, I would've thought the factory switched to the roller bearing set up for a good reason, other than saving the company a lot of money on each unit made.
Kevin as always great series it takes a special man to dedicate this much time and effort in order to educate his followers! Greatly appreciated and Happy New Year to you and your family!
Great video. Can you explain the difference between tapered rods vs full width rods and why someone would choose one over the other when purchasing a new flywheel?
Gotta love how what used to be the standard tapered roller Timken became an "upgrade" because HD discovered plain roller bearings permitted robotic flywheel assembly lines. The Twin Cam is designed as cheap as it can be, like a large Briggs and Stratton. That makes the aftermarket gobs of money in both cases.
All these dudes going to Car College getting themselves in debt, when really all they need do is subcribe to Baxter and smash that like button. Dudes drops more knowledge bombs in a 30 minute bit than a Professor in a semester.
Thanks Kevin for another tech upgrade tip.You wonder,besides manufacturing costs,why HD didn't do this upgrade off the assembly line?The customer has to pay through the nose to acquire one a HD.
Very very detailed video. My buddy had his whole engine done with the Timken barring. I went the easy way out lol. I ordered a S&S 124 create engine. After doing the math it was cheaper. My buddy wanted a full on street and strip engine I'm fine with just a street sweeper. But I would like to swap out the s&s 585 for andrews 67G 😆
Man sorry and I hate I missed the live stream I unfortunately got covid and was napping. I had my evo motor reworked and did a temkin bearing conversion on mine (said my mechanic) but he didn't do the bottom end it was pistons,cam and heads so not really sure which bearings were changed lol. Great video as always
Looks to me like planned obsolescence so things will wear out faster then you can buy another motorcycle to keep them in business thanks for all the educational tips
HD chose roller bearings so they could partially automate engine assembly. Watch videos of the line. Rollers saved HD millions in labor but they cheapened the product since the Timken is acknowledged superior and worked fine since 1936.
This is another excellent video, You did a good job explaining the laws of physics, complex engine dynamics, forces, and load that the crankshaft goes through. I love the Timken Bearing Conversion and see the value in the upgrade. The video left me wondering what would be the extra cost in the upgrade, If you were rebuilding a Twin Cam or M8? Again,, THANK You for shearing your knowledge with us.
Can’t wait for the next vidya. Awesome stuff glad I found this channel. Being a mechanic and owning my first Harley I now know how they are put together and what to do later on for upgrades
Awesome video! Suggestion? Countersinking the holes prior to tapping is a better procedure, it also provides a lead for the tap. (Sorry my 35+ yrs as a journeyman machinist talking...)
Just out of curiosity is that the same oil I used as an electrician to cut pipe threads.If so the jug used to state that the sulfur was there to help prevent infections in cuts witch happen to every body that works with their hands. I was hopping to watch this live but was drawn to the TV right before hand. I guess some times idiots happen. Great really great video. You have gotten very good at passing on information. Thank You. Mike from Maryland
i had heard the same thing...but never confirmed. but yes....because it's universal for all materials and works for milling, turning, and tapping operations.
I appreciate the video. My shop said I’ve got too much runout and need to rebuild but this definitely shows why it cost so damn much but I see why it’ll be so much better than stock. Awesome video!👍🏽👍🏽
As a person who deals and sales bearings everyday not only is there Timken there is multiple other premium bearings out there ie SKF, INA is a premium bearing and they also a Timken bearing is a brand of bearing
I agree with everything you discussed, and timken was the first to produce tapered roller bearings but there is other manufacturers of tapered roller bearings if very high quality. I'm a fan of timken but am not committed to just their bearings
Timken set up take more labor time to set up, that's Y harley discontinued on later models, the non-tinking application they allow it the crankshaft to walk around That's side to side run out, most the slack is taking up on the sprocket side with your compensator setup!
I've never had a Harley, but this is a master mechanic sharing real knowledge, it's great to see. What year would make for a more robust longer lasting engine for Harleys, if you were to keep it stock?
on the m8 some builders will do Timken conversation and some wont i hear about the case cracking its hard to no what to do sometimes because you dont no who to listen to but lots of things are like that
Wow, what's new is old again. Before 1955, Harley Big Twins used individual rollers and shims. When they wore, ya honed or replaced the sprocket shaft race and thrust plates to fit bigger rollers. I machined quite a few old Pan, Knuck, and BT Flathead LH cases for the '55-up twin cone Timken set.
It seems best that I baby my 88 around from here on out and give up all my imaginary racing. Put, Put, Put. Thank goodness those D&D Fat Cat will still sound just as mean and narly.
Timken bearing or rollers bearing if torque properly from manufacture, owners shouldn’t worry, if oils are changed on schedules. I was told and heard other mechanics be gentle on engine breaking, that will put a lot of stress on your engine crank . People need to remember that this aren’t sport bikes when engine breaking.
great video kevin i think folks would have liked to see more on the taps and type you used and the actual tapping of the adapter in the case i could be wrong maybe i missed it ?
When drilling the collar holes into the case, I was thinking, “get them shavings OUTTA HERE! we do NOT want any metal shavings leftover inside the case.” 😂 Serious question tho, do you countersink the fill/drain holes as well? Or do you just deburr those ones?
@@KevinBaxter Yea, i was thinking a 0.005" to 0.010 " chamfer on the threaded holes to remove the "rag" along the edge s after tapping and then just knock the rags off of the edges of the fill and drain holes..
@@KevinBaxter good stuff. Thanks bud. I’m going to be emailing you within the next week or so via the website... A more general question but definitely needs more space for proper room for what I think the reply will entail.
I have respect for any man that does things the right way. You Sir do things correctly. That said it's a shame you waste such talent building what's likely the sorriest, weakest, engine design in history.
Exact reason I bought my 02 TC, along with I wanted a controlled fuel leak not injection. Such a great video Kevin. What if you already have a timkin bearing, do you just do a new set up? Thanks Kevin, learn a little more every time. Your Patreon is worth it’s weight in gold on knowledge alone.
Thank you Sully. Youve mentioned Patreon a couple of times. Maybe i should look into that. If it is a timken case, the races would be pressed out, new ones back in, and then same procedure from there.
@@KevinBaxter Thank you Kevin, much appreciated. Sorry about saying Patreon, I was thinking the donation monthly was done through Patreon. None the less, worth every penny.
I heard its not necessary to get a timken bearing upgrade on your m8 unless you are going to like a 140ci, whats your opinion on that? Also I heard its not necessary to do the timken on the m8 but should still do a welded or plugged crank for bigger engines.
Please have a look at all the videos in the TC vs M8 series. You will find the engines arent as different as people think. Being the M8 is capable of more bolt on power than the TC, if going into the bottom end, I would certainly recommend a timken if going 140hp/tq.
Hi @Kevin Baxter, what is the implication of you drilling the holes without the sleeve in place? Would they than be a tad deeper and the oil ones slightly shifted inwards as the thickness of the sleeve offsets otherwise? From my reading of Jims instructions for this procedure, they do it with the sleeve installed.
I wrenched on Harleys back in the 70s and at that time the Timken bearing was the rule, it had replaced roller bearings back in about the mid 60s or earlier, probably was a time when I knew the year but no more. So why did they go back to roller bearings? Saving money?
i may be misunderstanding your question....when i have the small orange bar in my hand, and a t handle, that is me hand tapping the small holes. Thank you!
Great question. this largely depends on the size of the hole, thread pitch, and material you are working with, if its a blind hole, and the type of tap. Its all about clearing the chips. If the tap clears the chips well, and its a soft material, you can run straight thru. There are industrial taps for steel and harder metals that are designed for production and go straight thru in the blink of an eye. For the DIY, i would recommend backing off just enough to break the chip. then continue. you may even have to remove the tap, clean, reoil, and go back at it. truly is a feel sort of thing.
Now I'm bummed. I gave my son my 2001 carbureted Roadking after bought myself a 2006 FI Springer.. We both did S&S cams, oil pumps and tensioners... Other than that, they are stock 88s. Is mine junk waiting to grenade?
Change your name to 'Einstein' brother... because you are the Einstein of Timken Bearing components, function, dynamics, loads, and a shitload of other pertinent data. WOW! (Raise that fella's pay!!!!!)
Timken is bearing manufacturer and they make all types of bearings. It looks like instead of "cone" bearings, Harley mechanics use word Timken, which is wrong.
I was wondering what the benefit of paying someone to upgrade the cases with all the work and expense involved makes sense when you can buy S & S upgraded cases with not only timken bearings but other upgrades like thicker walls and machined to accept larger cylinders etc for $1300 ? I'm sure there is a reason but being a machinist but absolutely not a Harley mechanic I'm a noob please school me ... Thanks
this only is recomended on high hp builds. if your jugs are already off why not do the bottom end anyway. stock bikes this is not an issue unless u drag race every weekend and beat the shit out of it
Why doesnt Harley just do this from the factory? Why do some of their engines have 13 thousandths of runout on the crank? People have been doing these conversions for like 50+ years lol
Great video but I'd like to know how much HD actually saved by deleting the Timken bearing. Did they have to delete because of the change in accepted tolerances of the crank?
Another great video Kevin. Really enjoy the real time unedited footage of the how to's.. The less editing the better! Really like the POV footage with the head camera. You're really taking one for the team wearing that ridiculous looking camera though :) Thanks for doing these.
