| my old 8640 has a CLUTCH LUBE PRESSURE light and whistle that stay on constantly. I checked the pressure and it is in spec. I'm in search of the sending unit switch but my tech manual isn't very specific as to it's location. It appears to be on the right side of the cab but that's all I can tell from the diagram.
The fluid level is up and the clutch filter is new. The tech manual says the lube pressure should be 42 psi with 110 degree oil and 30 with 150 degree oil. I didn't run it long enough to get it up to 110 but 80 degree oil made 60 psi at 2000 rpm.
There are no signs of any malfunction other than the warning light.
Can anyone tell me where the clutch lube pressure sending unit is located? TIA | |
