Yamaha Blaster Bottom End Rebuild

Follow along as we take our Yamaha Blaster engine from a set of case halves to a complete bottom end. Along the way we replace out clutch and install all new seals, Thanks for watching

[@silverandblack4166]

Thank you very much Mike - after 3 rebuilds over the past 4 years with our blasters your videos have become my exclusive reference. Each rebuild was a success as long as we bought Wiseco parts and followed the break in process correctly. All the best to you and your team. You deserve every bit of it.

I’ve been watching this video every other day for couple months now , I read all the comments, watched other videos too.what and what not to do. I’m pretty sure I can rebuild mine now . Mines a 2000

[@cjleh757src6]

How it go?

[@mikewood547]

Probably the best and most informative video I'v during my sons Blaster motor rebuild. Thanks!

[@kingquadking7005]

Loved how you mentioned HPM , they are amazing. Good job on the video, very helpful. I'm rebuilding mine as we speak🤘

[@kevinbeaupre8925]

Got a little play in the clutch basket (cushions wearing out)

[@Soldier2326]

Can I put 10w-40 oil Valvoline with the clutch basket side ?… The transmission side do I use gear oil ?

[@williamcrane9289]

How exactly do you torque the case phillip's bolts? i went 7 ftlbs and they stretch and snap? is there a specific way to torque them? Thanks.

[@OperatorASF]

Those timing marks on the clutch side have to be aligned yes, but does the connecting rod have to be in a certain position when lining up those marks?

[@mitchellchang8956]

Why won't this video play? By the way your videos are great! Just wish this would play. I'm going to be rebuilding my first motor on my own and I need this one lol.

[@grindinggearsgarage9578]

not sure. seems to play fine for me. possibly a region issue?

[@nickkrug8157]

Watch it at 360p resolution

[@jasonpowell3841]

Good info. A friend who has rebuilt a lot of these says the sprung washer goes on first on the clutch shaft before that larger washer. Babbits Yamaha diagram also lists this way, don't know how important that is?

[@bray1461]

Thats how i did mine little then big

[@xbulldog_gamingx2468]

My piston broke into small pieces what can i use to clean the engine. For to remove the metal pieces from the engine.

[@luisleon8173]

Do you have a vídeo on how to replace the shift gear in a 2008 Yamaha Raptor 250. I already replaced the clutch, but still having problems with the gears. Any suggestions???

[@grindinggearsgarage9578]

Luis Leon sorry do not. never took my 250 apart that far

[@dinozografakis]

Do you really need to soak your clutch disks overnight ?

[@beardedwilli]

Just wondering how long it takes to do a complete rebuild like crank, rod, piston, bearings, seals, everything on a 2004 Blaster engine.

[@whitneylynn8707]

no more time than it takes on a 88 -03 or 05 or 06 lol

[@Ian-ec9kr]

Never use a hammer or a mallet directly on a seal or bearing usd the old one to drive the new one in safe right and never fails

[@gtancoc7780]

oh

[@gtancoc7780]

oh ok so i

[@gtancoc7780]

you

[@gtancoc7780]

you can just

[@fabiomilazzo7467]

hei dude. I would be glad if you'd respond to this. So my start lever/pedal on my blaster doesn't really work unless I kick it a bit harder and then it engages. what do you think the problem might be?

[@adamsbikebuilds4265]

Replace the kickstart mechanism inside the clutch case

[@fabiomilazzo7467]

Thanks dude

[@fabiomilazzo7467]

If there are any metal shards in there do I have to replace all of the gears inside there?

[@FloridaaboysTV]

Amazing

[@Ian-ec9kr]

Never use a scre drive to remove seals pose the risk of scoring the metal us a tool lisle has a great product

[@guillermoderivas5494]

How did u get out the crank??

[@TEAMCREAM_96]

Easiest bottom end ive so didnt even need a case separator

[@jessietober]

What about the rubber band that's supposed to be in-between the second clutch plate

[@1MACVSOG1]

Please explain im rebuilding one of these and I found some weird looking spring in-between the 2nd plate but can't find anything about it?????????????????

[@2stroketyson79]

@@1MACVSOG1 it goes friction plate clutch plate then Spring clutch boss then friction clutch ext ext

[@silentsoul86]

I didnt see the metal spring like disk that goes after the 2nd friction disk installed......is it needed?

[@doug12382]

Yes

[@2stroketyson79]

yes it is

[@spiff2555]

So, I have an engine, in pieces, more pieces than shown in this video, what should I do? Rebuild it myself or have someone professional do it (I have 0 engine experience).

[@grindinggearsgarage9578]

pay someone to do it. engine rebuilding needs to be done correct. if something goes wrong there could be a lot of money down the drain.

[@bowhunter7565]

GREAT VIDEO!!!!! Can you help me plz, 2001 blaster, it starts, sounds good, but when i hold the clutch in and then put it into gear, nothin. I can feel it go into gear but when i let out the clutch it acts like its in nuetral, plz help

[@grindinggearsgarage9578]

first place to check is clutch adjust ment. make sure there is a slight bit of play in the line before it engages. after that pull thr clutch cover off and see whats going on in there. bad adjustment, worn disks. thst sort of thing

[@bowhunter7565]

+Grinding Gears Garage I broke one of the bolt holes in the clutch basket, should i just buy a new clutch basket and plates and see if that does the trick?

[@grindinggearsgarage9578]

+Bow Hunter there is a good chance you smoked the clutch disc as well. so new basket and plates should seal the deal. before you button it up put it on jack stands and sping the wheels in gear and make sure the clutch is working, may need help for that pat

[@TayParks]

I had the same problem it’s the clutchs

[@nathanladd7614]

How do I get the transmission bearings out of the left case?

[@2stroketyson79]

blind bearing puller

[@tonyhinton3916]

Thanks a lot...

[@the_ltz_guymaster7912]

how do I time the gears for more aceleration

[@grindinggearsgarage9578]

thats not possible. you can change the gearing of your sprockets to gain for acceleration

[@the_ltz_guymaster7912]

Grinding Gears Garage like i want a longer shift time

[@grindinggearsgarage9578]

longer shift time can be done by also changing the gear ratio. taller gearing allows for a higher top speed shorter gearing allows for a faster acceleration

[@luischavez3247]

I have a problem with my blaster is shakes a lot vibrates want to know if you can help me out with what that is is thanks

[@5_twenty]

the mounts could be bad

[@grindinggearsgarage9578]

could also be the balancer

[@tractormike6086]

Seriously you don't clean the motor before working on it? That thing is filthy.

[@tylerratliff6483]

Why can’t I watch this video? Anymore

[@jaybabybruh6115]

Did you actually torque them to spec

[@grindinggearsgarage9578]

i torque them all to spec. somethings just arent worth showing over and over again

[@2stroketyson79]

@@grindinggearsgarage9578 u put a few parts on wrong though lol

[@mikelwmc]

oh the hammer hurts! Cringe... Otherwise thanks for the video.

[@the_ltz_guymaster7912]

i want to build my blaster my way but ik nothing on how to fim them i pay for mine to be built up

[@grindinggearsgarage9578]

if you have no knowledge of building an engine i would pay to have it sent to a well known shop to be build. Ken o'Conner Racing is a huge Blaster/Yamaha engine builder.

[@speckbeer]

I appreciate the basics of this video but it has too many scary mis-steps and wrong information. The biggest thing is he didn't pre-lubricate any of it during assembly. His torque specs were wrong and the clutch wave spring goes on first next to the bearing. A copper penny is a lot easier and cheaper to find than a copper washer. Hammering on gears and bearings crooked? At least he could hammer them on straight if need be.

[@bray1461]

No jutter ring in the clutch

[@dominator2354]

does that center bolt need tightened on the clutch?

[@grindinggearsgarage9578]

the center bolt on the clutch is the adjustment. once you re-install the engine i would set your clutch adjustment then remove the out part of the clutch and tighten the two nuts.

[@3deetoys234]

Please tell me you got to clean that engine that is nasty

[@austinpalmer6711]

clutch hub nut is 7/8 not 19 dont ant people thinking they have the rong one on

Please fix cannot watch.

Why can’t I watch this video?

Watch it at 360p... something wrong with the 460p on his /this video

[@joshuagriffin5144]

I'm sorry but didn't clean the engine plus you hammer the bearing in this is not good practice!
