Honda Foreman 450 engine assembly 

For an actual, step by step video and doing the video by yourself, you done a damn good job. I’ve been an automotive mechanic for 40 years and have worked on chainsaws and small engines for almost the same time. I’ve run Four wheelers for over 25 years but have only started repair on them in the last couple years. Your transmission part in this video gave me a clear understanding ( that was my weak point). I mainly work on Honda and Yamaha’s now. This was a very straight and down to earth take. I felt you done well on the explanation of each step. Awesome job! Keep up the good work and videos!

Very comprehensive instructional videos, well done! If you have a chance, I think a video on Honda carburetor removal, cleaning/rebuild and installation would be very popular.

I replaced my cases and the transmission will not shift, shift drum not trying to turn, I haven't installed the clutch assemblies yet honda foreman 450s thanks

Can't find a video of lining up the balancer and crankshaft

Thankyou for sharing this video! It was very informative, useful and easy to follow along with. I just put my '04 foreman 450 back together following your directions

Hi Four Wheeler Doctor, We did shift shaft on TRX450FE ES, after buying second hand engine to get the shift shaft! All back together runs really well with pull start, but wont run on the starter button depressed. Solenoid good, starter running when out of vehicle and earthed out on body. When back in engine no go and solenoid clicking. When my jump starter is full charged going to remove battery totally, to rule out battery short circuit. But i have had another thought! What if the neutral/reverse or gear position switch assembly was not in neutral position would this cause this issue? Pretty sure we doubled and triple checked on assembly, but still running beautifully with pull start. So also thinking not possible if running perfectly on pull start! Trying to think outside the square now! Key on neutral N is displayed with green light as well. Running beautifully on pull start, been doing my head in! I have been watching your videos they are famous. Anything you could think of would be appreciated Thanks heaps Donna in Australia

I was wanting to see if you can rebuild an 2007 brute force 750. I would like to talk to you about it. Thank you!

On the piston mine has an arrow that says ex. Where does that side go, intake or exhaust? Please help me

i can't even get a filler gauge under the exhaust side even when it's all the e way loose any ideas

When u connect the crank casses together should the output shaft for the transmission freely spin, befire I put the casses together it would spin back and forth till it hit its limit but then I put the casses on and there’s no movement on the output shaft but the unit that holds the shift forks moved how it should

quick question..... I have a 2000 450es complete frame, minus motor. Then I have a 2002 450es complete motor. Wiring plugs out of the2002es motor is different and won't plug in to my 2000 frame harness.... There's 2 plugs out of a 2000es and 3 plugs out of a 2002es. Can I change the flywheel, stator, and the shift sensor out of a 2000 450es motor to make my 2000 harness work. I see the stator, flywheel have different numbers between stated years. Then that shift sensor next to the stator also needs to be changed so the wiring plugs matches up to my 2000 wiring. Does this makes sense, and is it doable???? Your input is greatly needed... Thank you.......Pete

Ever done a 450 bottom end and only used rtv and not a paper gasket? Just wondering if it’ll work and not leak?

I have 650 v twin Arctic cat that has been rebuilt but it pops out of gear and the clutch squeals when in gear at stop any ideas are you open to work on it

very informational video. you know that engine well. im stuck trying to get my rear cover back on. any suggestions why its not sliding on?

Good afternoon, sorry, I didn't understand correctly about the rings. Is the one that goes first the one with a shiny part and the second one is the completely black one?

I HAVE A 2008 RANCHER 420 BLOWING COMPRESSION THRU THE INTAKE IN STEAD OF SUCKING ., ANY IDEAS WOULD BE GREAT, THINKING IT HAS JUMPED TIME BY A COUPLE TEETH ..

Love your videos man... not sure if I've asked before but how you cleaning out them cases I'm doing a 2016 foreman and trying to find out the best way to go about cleaning them thanks ahead! Oh and when you press the crank out will the bearing stay on the crank if so are they hard to separate without a special tool

I believe I have timing chain slap on my foreman 450. Only happens when it gets hot and I cut it off and then restart and increase rpm quickly. I already removed tensioner and it seemed ok. maybe a little weak so I took it apart and increased spring tension. Still doing it. Only 713 hours 3000 miles

I have followed this video to the T…. After it’s all back together it will only shift into first gear and back into neutral. If I take the front cover back off it shifts fine by hand all the way up to 5th and down to reverse…. Put the cover back on try to shift it and nothing first and neutral only I have done the pcm bypass kit and new motor and shift shaft it runs great new carb fires right up please help I’m lost at this point and out of ideas

only thing I wish is that you gave the real names of these parts. I am trying to look them up and can't find them..."Piece that looks like a golf divot tool" is not pulling up anything.

Y did u not put the rings on first😊 b4 putting piston on 😮

On the centrifugal clutch did you get one of those new cheaper ebay celox clutches while still using the original basket/drum ? How do they hold up ? Was going to go that route if my clutch was worn but read some questioning things and was going to get OEM clutch weights instead possibly. Thanks again for yr time and input

Separate question that relates and most ppl might be interested in sorry if this has been answered and I didn’t notice, but what was the reason you took this engine all the way down to split the cases ? Stripped drain bolt ?

Have you used or had any luck using after market cylinder jug and gaskets? I am about to rebuild mine and am ordering parts. It’s awful tempting to order for half the price. Also what is the part number or name of specialty tools I will need for a full rebuild?

Hi your videos are fantastic I have trx450fe, I'm in Australia and I'm wandering what brand of RTV gasket glue you use please. We had to R & R engine because it broke a shift shaft, apparently a bad batch in honda. Shaft unavailable found a second hand and wanting to put back together. Really would appreciate your experience and knowledge thanks heaps in advance Donna

I got a 450s that was given to me in pieces however the transmission gears were also all separated. Feeling a little lost on this. Do you have anything that would help me figure out the order of all these gears here?

Nice video thanks. please how can i get out or repleace the cardan shaft??

Hi Doc, Where are you located?? I’ve got a Foreman 520 that has got a rattling noise. My guess is the timing Chain. I might would bring it to you if you’re not to far Thanks Jim Harris

Want to do away with my 450 electric shift. Bought a manual shift lever. What HAS to stay inside to allow the manual (outside) shifter work.

I got a 03 foreman 450S. 1st thru 3rd is slipping when I accelerate a lot after shifting into that gear. 4th & 5th are working flawlessly. I’ve adjusted the clutches and nothing changed. Which clutch do I need to change to fix this?

About to crack open my 450, haven’t done one yet or had any motor open but I’ve got a 200 pulled and about to rebuild that and I’ve done some solid homework, I’ve got my Manuel, been watching your videos, thanks for all the information. But I’d like to know what you’d suggest for a complete engine rebuild not just top end. Maybe what bearings i should just replace while I have the motor pulled and split. The bike has high miles but transmission seemed to shift fine before etc I’m gonna do a complete top end job, valves etc lower end I have new cam chain and guide, new tensioner. Curious what you’d suggest to freshen up the clutches or just get new clutches ? Should I replace certain one way bearings ? Was gonna do the shifter seal but any other seals I should look to replace besides the ones between the cases

Thank you for your video! It has given me the confidence to tackle a case blown 450 s. I have one piece and a small spring like one from a pen I don't see in your video. Can I send you a pic for identification?

Do you do any work on a motor sent to you via FedEx or UPS?

I'm having an issue with the transmission on mine. I split the cases to clean the motor and when i put the 2 cases together it only shifts in reverse, neutral and first. If i take the cases back apart, I can shift through all of the gears if I use enough force when twisting the shift drumb. Ive taken thos transmision apart at least 15 tiimes and use the parts diagram to make sure everything is right and still no luck. Can you please help?

What if you can't get the thing in neutral, how important is that.

Good channel 🏁

Where is the tear down videos for this reassembly? I think you mentioned a previous video but it’s not on your list.

So when I put my centrifugal clutch in used the tool and tapped like it said. Now my crank is walking back and fourth in the case. Could it be that I knocked the crank bearing out of its race? Or busted the bearing when I tapped to set centrifugal? And suggestions to fixing or just go ahead and tear down? 2nd time being in bottom end. Thanks!

I bought a 2002 Foreman 450 FE ES. Only 1600 miles, had a couple broken gears that I had to replace, and he gave everything in pieces. This video was great for helping put the engine back together. I think he broke the neutral switch. I have it all back together and I got power but since it doesn’t show in Neutral I have no spark. Is there a way to test that switch without pulling it all apart?

Where you located? I have a 450 that needs some attention.

You still active on this channel? Im about to do the same kinda would like some help If I needed questions get back with me thanks

I have a 400 foreman followed your video step by step but it will only shift into 1st neutral and reverse, can’t figure out the problem any help would be great!

I got a kit off ebay installed it and oils is leaking Out of a hairline crack on the new jug. Have you ever had that problem?

🙂

Do you still recommended the KMC chains? Or what would you use today? Did you see my video with the smoking what would cause this on 6 hours on a new top end rebuild? ru-vid.comKHB9tWs9VXo?feature=share
