Honda CRF450R Bottom End Rebuild | Part 3: Assembly

[@wesbuy]

Thank you so much for this series. I built a 2008 Crf450r from pieces with no prior experience building dirt bikes just using these videos

[@rmatvmc]

That's awesome, nice work! Glad to know these videos helped you out! -Charles

[@jodysell2965]

Everything went great working with this video as a tutorial EXCEPT ONE THING, When upgrading to the Hinson Momentum Basket you don't explain that the stock Honda shim that gets pressed in behind the small gear is 20 thousands of an inch to thick! Luckily Rick Myers from Hinson knew exactly what the problem was with my inner clutch locked up on the basket. They pressed out the gear and replaced it with the thinner correct size shim that must be used with the momentum basket. Now my inner clutch and basket isn't locked together. Other than that it was a great video to use. Thank You Charles, and Rick Myers from Hinson! 😉

[@PatWendorf]

This series was amazing. I watched the top and bottom end videos and I don't even own a CRF450R anymore.

[@zachabbott6899]

I don’t even have a bike and I watch basically all of them 😂

[@mrcali818]

This video is very helpful and informative thank you Charles for making it, you gave me the confidence I needed to do this to my own engine

[@fabriziocostantini1099]

Thank you Charles! These videos are really well made and they helped me out loads!

[@oddball999]

Because of Your superb channel i have been in to buy one of these older hondas and just enjoy thanx

Pro Tip: Put your new main bearings in the freezer overnight, and then heat up the cases a little bit as shown here. The bearing will actually drop right into the hole, and you can feel (and hear) it tighten up in place. No driver needed, and you NEVER have to hit anything and risk a mistake / ruined bearing. This is the way the pros do it.

[@goodbyemr.anderson5065]

pro tip, doesn't work every time. I've rebuilt 100s of crf450s and even in the same year tolerances very slightly, some drop right in, some need a little massage. Also in his videos he says to freeze bearings, and heat case, so im wondering if you even watched the video?

[@VitruviunMan]

Yeah dude they don’t “drop right in” I have just done bearings on brand new 450 cases and even with heating/freezing they still took many whacks to seat

[@owen8868]

great video man you got great details and im going to use this video to help me reassemble my whole bottom end on my 2004 crf250r which is similar

[@sutrotka3828]

I’ve got the same bike and plan to do the same thing this weekend was everything in the video similar to your 250?

[@UFOBUILTCO]

Does anybody know what the torque value is for the crank case halves

[@romainberger]

Awesome job, thanks ! The explanations are clear and useful, it's too bad that you've got so little views... You deserve much more than that ! Remains the question for me, why do you change the retaining rings ? Is this something that I should consider to do when I work on an engine ? Thanks in advance.

[@denaself4547]

Helping my 08 build tremendously! Got my Kickstarter gear pulled and getting the momentum! Part number??? The one they say fits has gear already installed? Thanks!!

[@erlenspierre3157]

Please help me, I have a CRF 250r 2006, the transmission oil is in conflict with the engine oil, ah bnm, an idea please

[@yourselfdotcomlol]

The piece of rope on the gear jammer woulda worked as good as the 60 dollar tool its looped to. 🤣

[@nickhodges3847]

An old penny (from back when they had a lot of copper in them) also works great

[@josephpittala9146]

Can this assembly video also be applied to my 2004 TRX450R? Seems close visually from the outside. Nice video easily understandable.

[@tayallen7986]

Yes

[@deivitcbarje9558]

Chicos ! I'm glad for to see your videos !

[@jorgemercatali9319]

Super helpfull!!! Many thanks !

Glad it was helpful!

[@danielmcguire6830]

How much would it cost me to just send you my 03 crf450r engine and have you do your thing because your clearly educated and actually cared about everything you touched and i like that

[@esfahanazeziran3641]

سلام ایا این درست هست که در crf250rباید ازروغن موتور 10w40درموتور وگیربکس استفاده کرد ونوع متفاوت در گیربکس توسط سازنده پیشنهاد نشده اما بعضی از w80واسکازین در گیربکس استفاده میکنند من میخام بدونم سازنده چه پیشنهادی داده ممنون میشم درست ان را بهم بگید❤

So helpful greatly appreciate 🙏 GODBLESS

[@jamesbramblett3346]

Nice job on this lower end rebuild. Perfect timing for a refresher on putting my 06 450x bottom back together. Thanks

[@rmatvmc]

Awesome, glad it was helpful. Thanks for checking out the videos!

[@steadfastjack277]

Rocky Mountain ATV MC quick question. How many hours do YOU go before replacing bottom end? Thanks in advance 🙏🙂

[@milehigh3054]

What's it cost to have the no 5th gear problem fixed?

[@Dreadfullemon62]

I have a question I bought a used crf 450 r went to change the oil filter and when I took one of the bolts out the threads on the casing came out with the bolt and now it leaks oil slowly what are my options for a fix ?

[@ericgreen5605]

yall could make some of those bolt location holders in lexan or plexiglass and sell them. I would buy one

[@josephbenson7888]

Hey got a problem with the transmission not shifting. The shift drum is fine but some of the dogs on the fixed gear are worn all on one side can that cause the transmission to not shift

[@rmatvmc]

Hmm...does it happen in every gear? Is the clutch basket and hub notched? I'm assuming you already inspected the shifting mechanism. ...Rounded dogs will usually cause it to jump out of gear. Definitely get any with damage replaced. If it did jump out of gear, it could have bent some things. Check the shift forks and shafts. Let us know what you find. -Charles

[@ВячеславЖуков-с2г]

Good afternoon The video at 6:22 shows the wear of half of the crankcase where the oil pump is installed. Is it necessary to repair the crankcase in this case? Could this defect be the result of a decrease in pressure in the lubrication system?

[@rmatvmc]

I don't see anything that's concerning. -Charles

[@robertwoods2505]

Great job brother! Does it matter if the curved over side or flat side is out regarding the thrust washer between the basket and hub? Thank you and Happy Thanksgiving!!

[@coryprice3576]

Where can i find a oil passage seal. Mine needs replaced and cant find what i need. Would you happen to have a link to it?

[@rmatvmc]

To make sure you get the correct part for your bike, your best bet is to search for the seal you need in the OEM parts finder here: www.rockymountainatvmc.com/oem-parts

[@number7oneone]

L side engine cover cannot take 9 ft lbs of torque. I was starting to pull out some shavings from multiple threads after 8. Had to back out and hand tighten it criss cross. Other than that it was a very enlightening video.

Hello i just want to ask if somebody can tell me where i can find all newton meters for the whole engine (torque) For every screw in engine for honda crf250r 2017 I have a service manual, but it is not written in it Please help Thanks for your answer

[@juicelife2228]

When you put the palls in at 19 minutes they do not line up with the notches Now does that mean you skipped apart and put it in gear? Last I know we were in neutral

[@goodbyemr.anderson5065]

Amazing videos. Its always great when you can find videos of actual mechanics with professional knowledge on rebuilds. Many people have been led astray from backwoods hacks posting videos, and doing it all wrong haha. You got a subscription from me!!

Hey Charles!, rebuilt my 2005 just like you did.... I have a problem..... Mine will not start. I'm thinking it is the stator. compression test is 6% leaking at rings. timing is perfect. bike started once at high idle with choke on of course. turn the choke off.... bike sounds like its flooded with fuel which causes it to die. ever since bike will just backfire through the carburetor. Brand new OEM head and valves along with cylinder a piston. basically a brand new bike that wont start. do you think its wiring?? none of the wires seem cut or burnt, although the stator looks funny but I have a good spark when testing. any suggestions would help Thanks your biggest fan, Wyatt

[@RidePittsburgh247]

Wyatt Glass you figure that out?

[@wyattglass3581]

@@RidePittsburgh247 I just bought a new stator lol old stator had a small slice in it so I'm thinking that is the problem. I get off work at 2 so I'll find out later if that is my problem lol Are you having the same issue??

the cam chain guide plate bolt wat is the torque spec

[@senditspecs43]

is this the same for a 250 looks similar

[@motomechanic5711]

yeah

[@yamahaelsker]

Why do you assemble the right side, and then fill it in the left side? Is it just because that its easier that way with the oil pump? 😇

[@rmatvmc]

Yeah, it's a little weird but it's actually the easiest way to assemble everything while avoiding mistakes. -Charles

10:00 how much torque for that crankcase

[@andysk4993]

I am rebuilding my 05 crf450r and the transmission is binding up in a few spots but then breaks loose it also doesn't want to shift into neutral anyone have info on that

[@leesbikelife2231]

I have the same issue on my 09. Wont even start now. It has no neutral and will jump Into gear when trying to kick it

[@haydenbentley8331]

Great video but I wouldn’t recommend following his advice on the torque specs. I have the same year and model and his torque specs were wayyyy too tight. For some reason my shop manual does not have specs on everything

[@rmatvmc]

On what steps? Those specs came directly from the service manual. -Charles

[@haydenbentley8331]

@@rmatvmc I had the gear drum stopper arm bolt snap at 7ft lbs the arm was too tight to move at 7 ft lbs which I realized after as well as a case cover bolt snap around 6ft lbs so it could just be my tools not being to spec but I will say I did go buy a brand new torque wrench to use for this build. Is there a shop manual you would recommend for the bike?

[@haydenbentley8331]

I have the Haynes shop manual and I’m not impressed with it at all.

[@rickymclain3017]

When they put the transmission together and add the crank then put the cases together just to flip it over and separate the cases again. My question is did they do this so you would ruin the crank bearing, there's no reason to add the crank till the last time you split it. Not only that but if they put the transmission together in the left crankcase there would be no reason to have to flip it over and risk your crank and transmission seals. 1 more question. I've noticed all the different videos do it the same way, is this due to A. All the companies got together and decided this was a good way to make money off the sale of seals and gasket. B. Everyone is retarted. C. Everyone is retarted?
