1985 LT2350R engine counterbalance? Nasty vibration

[FPMXer]

I labeled the counter balancer and pointed out the dot on the crank gear. There is a dot on the counter balancer gear that needs to align with that dot on the crank gear. You don't need to remove the clutch at all to align the dots. Just remove the nut on the crankshaft and pull both gears off and look for the dot on the crankshaft underneath the crank gear. then move the counter balancer to align it's dot with the dot on the crank shaft and then slide the gear back onto the crankshaft aligning all 3 dots. I believe the nut on the crank shaft is left hand thread so don't zip it off too fast with the impact or bad things can happen. Someone should be able to confirm if it's a left hand threaded nut or not.

My bad you will have to remove the clutch basket. And yes those are two of the dot's that need to be aligned with the dot on the crankshaft. Take your time to make sure all three dots are aligned before you put the basket back on. Your half way done.

Oops. I gotta remove the clutch basket anyway, I was trying to remove the nut and had a prybar in between the posts in the basket and snapped 2 of them off.


Thanks for all your help! Dan

That sucks. I use my impact to zip the nut off the hub without holding it. If you have the pressure up enough it will come off. I did someting similar to that and broke half an ear off. If you put a penny in between the C/B gear and the crank gear it will help tighten and loosen that crank nut.

Woops....About the counterbalancer, This is an easy fix.
Just line those two dots right together, then reassmeble.
Take your time on dissasembly & Reassembly to make sure you have everything right.
Talk to Member "Nelson" I do believe that he has an extra basket for the 85-86 year engine.

So the LT250R only has 2 dots not 3 like the zilla???

[jsmstorm]

Yea there are only 2

[BadAzz88GT]

OK, so if there is only 2 dots do I remove and turn the counterbalancer gear or the crank gear? I dont have it apart yet, is the crank keyed or something making it only one way to go together?

[jsmstorm]

They are both keyed I don't see that it would matter which one you remove. The crank is a reverse thread though just something to keep in mind

OK, this looks a little better. Thanks guys for all the help! Dan
