South Ga | Got 77 model 4430 that all but stopped pulling and I’ve had some time to tinker with it over the last week and need some help pinpointing the problem. It has low pressure (115 psi) on the test port on the clutch valve but it has good pressure (within spec) on the pto valve. Put new o-rings and gaskets on everything in the clutch valve housing, springs were fine, tried adding shims and made no difference. Am I wrong thinking my transmission pump it fine if I have good pressure on the pto test port? Where do I go next?
Thanks, Zach | |
