an engine i worked on had a lot of rubber in the oil filter strainer down the front/bottom of the r/h engine case
so i thought i had better check the clutch basket.
it looked ok, but when i held the alloy basket, i could move the gear on the back forwads and backwards.
that shouldn't happen with a good basket.
so this thread shows how to repair a noisy clutch basket on the above models
it is the same for any of the rear clutched engine too.
this is pretty much the same as Sean01s' thread but with a few more pics- http://www.miniriders.com/motor-tutorials/31107-china-start-any-gear-clutch-upgrade.html
here is a noisy 155Z clutch basket
the studs that hold the steel gear and backing plate to the alloy basket need to be carefully drilled out
i used a 4mm drill bit and drill straight down through the centre of it using a drill press.
once the rivets are drilled, you can just turn the head of the stud off with a pair of pliers
then the thin steel plate can come off, be careful not to bend/ warp it etc
this is what i found inside the clutch with it pulled apart, see the rubbers have let go
those alloy rounded triangular shaped bits should be sitting centrally in the holes of the gear
this is the donor clutch, off a Lifan 125, the rubbers were in excellent condition.
and this shows the old ones next to some good rubbers (out of the 125 idler gear above)
you'll need to drill the whole way through the basket so it is ready to be tapped with and M6 x 1mm tap
i countersunk the basket and backing plate too so i could use some 12.9 bolts i had
new/used rubbers fitted, loctite threads ready to be assembled
and all put back together and ready to be fitted
