Hott Boy's Garage - Ep. 12 - Honda TRX450R: Splitting Engine Cases & Crank Bearing Replacement

[@bobberg8860]

Thank you for creating this video. Without this video I would never been able to do a bottom and top end rebuild on my 05 trx 450r. Service manual not descriptive enough. Thanks again

[@HottBoysRacing]

Glad it helped!

[@oljimmy7753]

Unreal this video, watched it countless times, and countlessly have torn my motor apart and been saved numerous times because of the little detailed stuff you included. Thank you so so much for making this video

[@HottBoysRacing]

Glad it's helped!

[@cuel-stuph-iz-heeir7804]

Thank you Gary, very helpful and well put together video.

[@TRX450RVlogger]

Glad you go way more into detail then I can do. You have more patience for video making. My other channel is TRX Tech

[@HottBoysRacing]

Takes forever to edit these vids! haha

[@jacobbutler7942]

This video wasn't made 3 months ago when I was doing my research. I'm so glad I found it now (: thank you very much for all the details. This is pure gold

[@HottBoysRacing]

No problem, glad it helps!

[@AsianATC]

Just tore my engine down tonight this is going to be so helpful when I go for reassembly! Thanks!!!

[@HottBoysRacing]

Hopefully it helps! Thanks

[@BASSMASTERFROST]

Thank you for this video! I bought a 05 450r didn’t know that much about it had some trouble and I used this video to split my cases and fix the issue. You covered literally everything except the kickstart for mine. While I still had the service manual to go by I found this video to be more helpful then the manual. Thank you!

[@HottBoysRacing]

Great - I'm glad to hear it helped!

[@MadSharkbite]

Great video man good work!

[@HottBoysRacing]

Thanks!

[@datboi101truth5]

Best how to hands down!!!!

[@GThompson42012]

This video is a life saver! Thank you so much h for this.

[@codynixdorf1507]

That’s an awesome video man, definitely gonna help a ton of people!

[@HottBoysRacing]

Thanks, hope it does!

[@thaman20071]

Man that's a badass engine u have over there 💪🏼

[@jbplays7302]

Thank you for the detailed video! I've got a stock 05 450r that overheated and popped the head gasket. I'm expecting the head to be at least slightly warped. Any advice on who to send the head to?

[@HottBoysRacing]

I would recommend Racers Edge AZ or Oregon Coast Powersports (OCP)

[@maxxisrazr2012]

"17:33" Do you clean the oil strainer every so often as part of maintenance?

[@HottBoysRacing]

We usually just do it as part of splitting the cases.

[@leewhite414]

Awesome vid 👍

[@HottBoysRacing]

Thanks, appreciate it!

[@izzyharris8964]

I have a question do you have to split the motor to change the oil pump I see the star part inside the motor once you slide the gear out does that come off as well ?

[@HottBoysRacing]

Yes you have to split the center cases to change the oil pump. It's 3 pieces total.

[@salsipuedesatv3152]

I would like to know if the crankshaft bearings go in an exact position or in any way

[@HottBoysRacing]

For 04/05 TRX OEM crank bearings - it doesn't matter which way they go in

[@ashtongreensberry4417]

Great Video

[@HottBoysRacing]

Thanks!

[@tayg9175]

Thanks 👍🏻

[@danielwalsh7310]

Hi in the middle of doing a rebuild on mine and I toughht everything was OK until I seen a post on Facebook off another person doing a rebuild forgot the d ring on the countershaft. This made me think have I done the same, do I need to open up the bottom end again to do this

[@HottBoysRacing]

Are you talking about the rubber ring/seal that goes onto the countershaft behind the countershaft/sprocket spacer? If so, no need to split bottom end, you can just pull the spacer/bushing off from the outside and install the ring there.

[@danielwalsh7310]

@@HottBoysRacing that's good news thanks really appreciate it also which way would you install it round side out on the shaft??

[@HottBoysRacing]

​@@danielwalsh7310 - just to confirm, you are referring to part-num: 91201-ML3-873 (#35 on this diagram: www.partzilla.com/catalog/honda/atv/2005/trx450r-a/transmission ) correct? If so, I'm not sure for the "correct" orientation - but I think I've actually installed it both ways and haven't had it leak.

[@danielwalsh7310]

@@HottBoysRacing ya that's the part thanks alot I just ordered one don't remember one being there tho haha

[@BrendanMX]

What kind of engine oil are you using? Ceramic bearings?

[@HottBoysRacing]

Motul 300v engine oil - and yes, this particular engine uses hybrid ceramic bearings throughout.

[@jeramyBOXING]

Hey can I ask you a question about my phone Honda 450 er

[@rickmachuta4115]

Can I replace the shift shaft without removing clutch basket?

[@HottBoysRacing]

I've tried it, but no, on the 1st gen TRX I wasn't able to replace the shift shaft without removing the basket. (haven't tried it on the 06+ TRX tho)

[@chaseb7935]

06+ I was able to pull shift shaft without pulling clutch basket.

[@pluto6x108]

Why would my crank move when case bolts aren’t tightened but not when I tighten them? Anyone got any information?

[@HottBoysRacing]

Anything on the outside that would keep it from moving? right side gears? cam chain binding? stator/cover on? if not, i would check to make sure the bearings are seated all the way and check to see what the width of the crank is

[@javinava551]

Hello, crankshaft seal, are you 29,9/44/7?? I am 30/44/7. Good video

[@HottBoysRacing]

I'm not 100% sure - but you'll probably need to order and use the same size that came out of your engine

[@williamhott2982]

my name is Butch Hott enjoyed Video

[@HottBoysRacing]

From one Hott to another - thanks for watching!

[@kennynadeau17]

My clutch push rod want come out?!? what is my issue here, it moves like half an inch and stop flush with the hole.?!?

[@HottBoysRacing]

Move/rotate the clutch arm on the left side of the bike to see if that will allow it to pop out

[@kennynadeau17]

still wont come out... 😢 thanks for the reply and awesome work you do by the way! i like your videos🤘🏼

[@HottBoysRacing]

@@kennynadeau17 appreciate it. Unfortunately - I've not had this happen. Wondering if you might have a burr on the rod that might not let it come out

[@HIinfidel]

Why put the left bearing on the crank first ? Why not just install into the case? Are you using the updated 04-05 crank

[@HottBoysRacing]

Definitely more than one way to do it - this is just how we prefer. And yes - for stock builds, always OE updated crank and bearings.

[@mauriciorevillaa.7181]

Hey bro, where can i find the crank collar?

[@HottBoysRacing]

As far as I know, you can only get the collar with the right side bearing - OEM part number: 91008-HP1-672 - I use PartZilla

[@jeromewells151]

How much HP does your engine have?

[@HottBoysRacing]

Last time I had it on the dyno was 3 years ago and it made 95hp at the wheels.

[@jeromewells151]

What size is your engine? And what size is your stroker crank shaft?

[@HottBoysRacing]

@@jeromewells151 - 647.69cc. Crank is 74.8mm (+10mm)

[@devioussounds]

Fuckin great video 👍👌

[@HottBoysRacing]

Thanks man - hoping it helps a person or two
