Mack 9 speed range change


Recommended Posts

It is pretty basic on a 9 speed. There are only a couple of o-rings on it. The shift cylinder is on the underside of the cover and the fork is attached to it if you havent seen it already.

If its jumping out of high then check the fork, they will wear pretty thin and will in turn burn out the discs in the clutch pack. Fairly common.

If the cylinder is stuck and leaking air then you can get a kit from mack or gleemans. Skip
