View Full Version : Clutch - what if I just rebuild the centrifugal?

Riding the Big Red around in the snow today, I can tell the clutch is slipping pretty bad.

Is it likely to be just the centrifugal clutch, or do I also have to replace the disks and plates in the manual clutch too?

The centrifugal clutch just allows you to take off smoothly - In ANY gear, that can be an issue with automatics as people don't know there in 4th gear, they coast to a stop and try to take off from a complete stop. Thats what really kills the centrifugal clutch.

The MAIN clutch, acts just like pulling in a clutch when you shift. There is an internal mechanical mechanism that does it for you......

SO, if it slips while your already rolling along and get on it - thats the main clutch. You'll need the 5 or steel and fiber plates.

If from a stop it goes no where, then the main clutch is WAY out of adjustment and it's like your pulling in the clutch and trying to move forwards. If it is not THAT adjustment and they don't get THAT FAR out of adjustment in a day, then it's a centrifugal clutch issue.

If you were in gear and rolling along in the snow while it slipped (and not the tires slipping because of the snow) then you need a main clutch as described above.

GOOD LUCK!!

Simple info:
If the motor must really rev up before it takes off: Centrifical Clutch

If the clutch slips the more load you put on it: Manual Clutch ( Take off in 2 or 3rd gear from a dead stop and clutch slips )

Well, in 6" of wet heavy snow...

1st - spins the tires okay
2nd - doesn't spin quite as well
3rd - won't spin the tires at all

Sounds like disks and plates... There's no more adjustment left there.

Not surprised. We beat this poor old trike on the farm for 20 years, pulling way too much with it. I rescued it from going in the junk pile.

Is there any harm in running it until it won't go any more? It's perfectly fine for riding on dry ground right now, and I probably won't use it for much more than ferrying stuff around my property.
