With the engine
off, I can feel something inside rub when I turn the coupling by hand, it (in my mind) could be a warped clutch
plate or something that just barely grabs as it spins(when it is running). This would explain why I can stop it with my foot or hand, but when I release, it picks up speed again.
As far as hydraulic red gears go, when the engine
is not running there is no pressure, thus no possible way to engage the gear
(at least on my model)
I remember hearing something about only being able to freewheel a hydrulic transmission/reduction gear for about 4 hours before bearing damage can occur. (this would be due to the fact that since there is no pressure in they system the fluid does not lubricate the bearings.
As anyone else heard about this?
