ok tell me whats wrong!!!!! how come the "keyway" in the counter balncer keeps frigen braking?????? i don't know why this keeps happening... i have changed almost everything ... i hand a bad basket- then got a hinson.. i had the whole motor apart did the crank and all that goes with it.. could it just be the counter balncer it self?? or maybe the bushing & bearing the basket rides on?? i realy need to fix this!!!! last time it was vibrating so bad the bolt from the power valve (the one under the jug) came lose and fell into the motor! ya it blew the clutch basket to dust!!!!!! i don't want this to happen again it!!! please help!!!! thanks for your time!!!! joe

 

With the counterbalencer drive gear off does the counterbalancer spin freely? If not replace the bearings. There is no reason for that key to break, there is not a whole lot to it.

Is this an 87 - 92 motor? If yes make certain all THREE marks on the gears are lined up on reasembly.

 

yes with the gear off it spins good... the year is 1992.. you say three marks????? i only know of two marks on the counter gear and the crank gear.. is there another??? if so where is that bitch??[img]i/expressions/face-icon-small-smile.gif[/img] man i can't take it too much longer it's going to 80 out today i need to ride.. please reply..

 

The third mark is on the spline of the crank. The mark on the crank spline must line up with the mark on the crank gear, which must line up with the mark on the counterbalancer gear. Common mistake, look in the clymer manual it shows the marks clearly.

 

dude your the man!!!!!!!!!!!!!! thats real cool i will do it as soon as i get out of work.. i'm getting out at noon to go ride.. thanks again if there is anything you need let me know and maybe i could help you the same!!!!! hey do ya know anyone who needs 85-86lt parts?? i have some stuff left that i can't use!! thanks

What kind of 85-86 parts do you have?

 

haha greenbud, i like your quote, "a friend with weed is a friend indeed". its from the most rediculous movie ever, leprechaun 5(?):leprechaun in da hood. lol thats so funny to me for some reason.

 

my brother had the exact same problem with his '90 LT... the thing was a real basket case...
we had to replace the crankshaft too. make sure yours is true.
the what we found wrong on the counter balancer was that the nut that secures the gear & weight was tight, but the gear and weight were both still loose on the shaft! what this caused is every time the motor would make a revolution, the weight would shift on the shaft, eventually with enough force to shear the key. our solution was replacing the whole counter balancer assembly with one out of a bottom end we bought on ebay for parts. we were just going to put a washer on the shaft so the nut would secure the weight & gear, but took the other way.
the cheaper solution: go to a specialty fastener store(not just the hardware store), they have dimensional washers that you can fit to the end of the shaft & not be too big(avoid interferences)... so that the nut pushes against the gear & weight & secures them properly.

 

well i went out yesterday after i fixed the three marks and......she's good back to the norm...rippin *****!!! thanks alot for all the info form all of you!![img]i/expressions/face-icon-small-smile.gif[/img] as far as the 85-86 parts..i have fr-shocks,full set of a-arms,fr & rear brakes-res's and lines, gas tank, oh ya ihave a brand new water pump impeller & shaft(both are brand new) i think thats it ?.?.? sh**!!(thats way they call it dope) i have a grab bar, rad,fender braces,head light and tail light,full electrical cdi,coil,ect.... most all of this stuff i can't use on mine so it does me no good.. well let me know i'm sure we can work something out[img]i/expressions/face-icon-small-smile.gif[/img]
