Clutch Clutch Balls-- Who's counting ????

[Maxx Ported]

So Sad, the Quaility sucks and they CAN'T even put enough bearings in the assembly
My first clutch problem (less than 50miles)the pressed race came off and the ball bearing fell out.
My second clutch (80miles)was locking up. took it apart and found the bearings flat-spotted..and only 54 balls. (will hold 58.)

So after lot of searching,, Finding a supplier of grade 25- 3mm- ball- bearings,,i repaired both clutches, no more high pitch singing sounds

So I took apart a NEW engine to look at the bearings,>>ball count 52
found dark gray, out of round pitted BB lookin balls?? looks like ANOTHER part to THROW away.

I just don't think so -- I would think that some of this has been done ------

ON PURPOSE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

since at this time no one else offers anything like the same kit for same money
they have got everyone by their mountain rocks....

ride that thing

Who was the supplier of these engines with the crappy bearings? Whoever they are, they need to know that their engines are coming with substandard parts. The importer will then put pressure on the manufacturer to fix the problem or lose business to a manufacturer that will provide an engine kit with acceptable quality at th same price. I've said before that I can forgive a lot considering the engine kits are $99 + shipping, but internal parts like bearings, gears, pistons, and cylinders should be of reasonable quality.

also whats your riding style.. are you burning the clutches out due to from stop racing or just a casual rider?

Excelant pictures Max and cool for pointing this one out.

That section of the clutch assembly ought to be part of the regular maintenance thing.
Not many know these small bearings exist until it's too late.
One way of "sudden death" to those bearings is to wash the clutch assembly
when not knowing the bearings exist, ride it 50 yards and sieze it all up.
However, it can be prevented if you remove the clutch using the special tool, and behind it are 3 tiny holes and lube the bearings with a spray grease from preassure pack can if you don't want to take all apart. Get one that has a tube that goes into the spary nozzle.

It is a good idea though to take it all apart when brand new, replace the bearings with higher quality bearings, moly grease, and keep it maintained.

makes me wonder

well that sounds like a GOOD IDEA Bolts

and after looking at those bearings -- should be a must !!

fill em up with all new bearings and grease

ps -- fill bearings until full -- probably more than amount furnished !!!!!!!

MAKES ME WONDER WHAT KIND OF (JUNK GREASE) DO THEY USE ?
DISTILLED COOKING OIL MIXED WITH BUBBLE GUM ???

not sure what to say about that except get it up and ready to

ride that thing

The clutch is not burn't/slipping..it's the bearing, that is poor quality, even when checking a NEW clutch, the bearings look like small apples, ( out of shape and pits).

Our driving habits are to pedal up to 10mph and let the clutch take over. It's when coming to a stop the the clutch grinds and jerks/locks up..

didnt mean to offend.. was just curious

 

[fetor56]

Who was the vendor & did u let him know so these basic(but very important) problems don't happen again?

Sometimes they can be out of shape when new, they are not always bearings, seems like pellets of some description.
Incredible insult to western minds coming out of MiCh.

Yep, that is the sure sympton, locks up for no apparent reason.
