Just acquired a '74 4230 syncro. The
rockshaft is very jerky when raising it.
Tonight I changed the fluids, hydraulic
filter and cleaned the sump screen. After
doing this I checked the pressure coming off
the gear pump at the clutch valve housing. I
did add two shims to get the pressure in
spec. It was good on all four ports after
doing this.
I have not got to check the main pump
pressure yet add it takes a different size
fitting. The rockshaft is still jerky after
all this. What next? Is there a way to
verify flow on the gear pump without a
special tool?
If we can get through this next will be
diagnosing a hard cold start condition to
make sure it is as good as I can get. Then
off to Tim S. House to get the steering
valve Rebuilt.
