Combines Cylinder speed declines

[Tom_Russell]

You will begin to notice hydraulic oil stains around the large variable speed cylinder drive sheave which means you will have to replace a couple of O-rings. Having a service manual and a young weight lifter will be very helpful. Once upon a time my son and I did it in a couple of hours on a Sunday afternoon. loosening the gigantic nut was the hardest part of the entire job.

if you do NOT see evidence of external oil leaks, the poppet(s) are leaking on the VS valve, might have a piece of oring, silicone or other object slightly holding the poppet off the seat. Pull the poppets and check for this.
