These changes do not change the fact that a gearbox designed for a 70 hp was put into a 100+ tractor with no significant changes. It is not inferior parts that cause a 1694 4wd hydrashift box to fail it's the power going through it. In the early 80's when original DB parts were still in use 1490's w...

Case did not alter sprag bearings and clutch plates, that is what they did wrong. The hydrashift unit was designed for a 70hp 2wd tractor and in that machine it work exceptionally well. When they put it into higher hp 4wd machines without any significant upgrades the problems started.

Once you are fully conversant with the hydrashift they are a relatively easy gearbox to both work on and fault find. Although caution must be maintained, it would be foolish to decide, after pressure testing, that it was a particular fault and just go to that problem area. I would recomened that onc...

Bosch pumps did not have excess fuel buttons, it was automatic every time you pulled the stop it went onto maximun delivery for the next start. It does not matter which pump you have the kits are the same. The fuel for the header tank is taken from the returns line.

What the last writer forgot to mention was the jacking off holes. After you have removed the four bolts, between two of the holes are threaded holes that you screw of the removed bolts into. This jacks the flange off the splines, it never slides. Don't forget the rubber disc.

How would you decide where to set the release bearing to? Try setting the release plates to the settings I have given and see if it works.

Hi Rob, Not to certain about your problem from the description, do you mean the lever won't stay where you put it? If so the lever friction brake needs adjusting. At the base of the lever are two nuts, loosen the locknut and tighten the adjusting nut so the lever moves ok then re-tighten the locknut.

They stopped fitting the lift latch. It was failing due to operators mis-using it. It is not recommended to isolate the 3 way as this can result in breakages if large implement is carried over roung groun.
