rebuilt hi/low clutch packs, resealed throw
out bearings new transmission pump and
clutch pressure around 150 after we shimmed
pressure valve, any ideas?

When I did a clutch job on a 4030,(has been 20 years), there is a needle roller #32 in the parts breakdown that is 2 different lengths, any way there was a short one where there should have been a long one, causing the same issue if I remember right. Found that while pressurizing the ports that go to the clutch from the valve housing(had valve housing off). Customer said the tractor was completely different after I found that. Bought new and it was 1996-97 when I worked on it.

I ordered that pin yesterday, I am not totally sure where it goes but I better find it, I will put air to it in morning, thanks!

Does 32 hold lubrication reduction valve in place? Where else does it go? thanks

One of my books shows 4030 clutch pressure is supposed to be 105-115 psi @ 1900 rpm. 150 psi? That would be kinda low for a 4430.
