who does/dosnt use thrust washers on their wristpin?there has been alot of debate about these darn things latley.mine broke and totally screwed up my rebuild and 2 different wiseco techs told me it was ok to not use them as long as you have them on ur crank pin.i dont think im going to use them this time around and see how it goes.its 2 less things to break.
so who all uses them and who all dosnt?

 

do lt250r's use thrust washers on the crank pin?

 

I'd check around before not using them. I know duncan has a trick to not using them but it requires piston mods.

 

just checked duncans website. requires special bearing. If you put it together without the washers the wrist pin bearing will move out of the rod and cause bearing failure.

the new bearing is wider so it stays centered in the rod. thats what the washers do. they have a piston kit with bearing for $145.
although wiseco probably knows what their talking about too.

 

yeh.i will.i calld wiseco 2 times to make sure and they both said the same thing.i dunno.i dont have the washers and were suppsoed to ride sunday.iv heard about the bearing thing.will a bearing from a rm250 fit?what bearing will fit a piston for the lt250r?i think im gonna not use the washers.ill take wiseco's advice and see if it all works out.

 

Where can the wristpin bearing go? My polaris 400 didnt use thrust washers.

 

on the LT there is a gap between the piston and the top of the rod thats filled by a thrust washer on either side of the rod. I dunno know why suzuki did this but it causes big headaches.

 

im going to see how big of a gap it is.if its not much im going to take wiseco's advice and not use them.if its a good gap im going to get harder ones made.

 

let me ask you this needaR. you have this build list under your topics were it says .030 over wiseco piston. when you took it apart it had the thrust washers right? so why not put them back in?

 

the thrust washers are broke.well one is and without them thats 2 less things that can break.
