splitting case, should I replace all bearings?

[skiboyracing]

I'm splitting the case, usually I replace all bearings through out the cases for all the shafts, shifter drumb, etc. Is this what most people do or do you just leave them alone and only change the mains? They have some miles on them considering it's a 92. Local dealer is saying they don't unless visible issues. Just wondering what works for others.

I don't... maybe if I was to keep the bike for a long while or the bearings were obviously screwed.

tough call though if it's a '92, my buddy lost his entire tranny on his '98 kx125 last week due to a bearing.

Yeah I always changed them in the past since I was in there anyways. For the cost of bearings vs time to fix later, I don't see any reason to change my ways now. Piece of mine I guess.

As long as you are in there already replace them even if you do not plan to keep the bike wouldn't it be great to honestly tell the buyer it is really rebuilt right.

It will make a difference in vibration. Mike the journals where the bearings ride. Check for grooves where the seals ride.

Do it, there cheap and it's already apart.

Yeah I just bought the machine and plan on keeping it so I'm doing it right (although I would regardless if I was keeping it or not). I'd just like to know exactly what I have instead of guessing and hoping things will hold up when I'm in th woods.

It's actually a 92 quadracer :yikes: for the sole purpose of taking my 3 yr old for some rides this summer. I'd hate to break down with him miles from the house :(


Thanks..
