Does anyone have the specification for the gear side clearance in the 420c pump?
I went through the entire hydraulic system last spring to fix a bunch of issues, but after putting the pump back together with new seals it is even worse than it was. Now that I need to plow snow it's dead.

Never mind, it had ice in it again. I probably just need to use heavier oil and I have added a drain valve to the tank so it can be easily flushed every year like it's supposed to be.
