D3B Steering

is it a dry or wet clutch arrangement? Is the linkage and valve end roller in good shape and linkage adjusted to spec?

It is dry and all linkage is correct.Have operated the cluch valve by hand and the track does not even slow down.

Appears the slave cylinder that works the steering clutch yoke is stuck....not uncommon, especially if left to sit for long intervals. You will have to get access to pry the yoke (hopefully) loose.

The cly is working,checked that befor I put the cover back on.I took the cover off and found that the brake adjuster was frozen on both sides.Got them free and luberacated up and checked everything out .I did not take the cluch out.I thought the break adjustment being frozen was the problem.That was some of it but not all.

If all that's working then it's time to go deeper...checking the clutch release bearings and bevel gear cross shaft bearings. Looking for why the yoke movement is not getting transfered to clutch release.

Should anything move when the Yoke moves.I could not see any movement in the area where the cluch is.How much should the yoke move.Does it move all the way to the stop or does it stop short of that point?
Also just put a new gage on the pressure test for the cluch cly.It reads 170 psi on the right and 250 on the left.Is this dif ok and what would cause the dif?

Have you changed the hydraulic filter and checked the pick-up screen?

As I recall you should see 400 PSI. (That's what I saw after changing mine.)

I'm with Bob on thinking the slave cylinders may be bypassing but you'll want to check these other items first.

The steering valves are pressure reducing valves. The more you force on the valves the higher the pressure that goes through them.
Worn bearings on the stems reduces the travel and thus release pressure. Weak or broken springs inside do the same. Good valves will let full trans pump pressure through(app 400 psi)
