Ok, update with pressures, etc from my 4230 with Syncro trans and slow hydraulics, which some times affects steering as well. No chatter just slow at any rpm. See previous 4230 posts as well.
As requested tested stand by pressure and it is 2250-2300 lbs at the remotes and test port on T Block where it tees off for the steering and rear rockshaft.
When testing pressure at the T block mentioned above when using the rear remotes pressure drops from 2250 to 1700. Then pressure drops to 700 lbs and stops working. Pressure slowly will build after about 10 seconds up to 1700 again and then drop to 700 and stop.
Clutch pressure is 119 lbs at any rpm and if front pump is destroked.
Lube pressure is 2-3lbs at idle up to 20lbs at pto speed.
We have tried to get to the pressure valve under the rock shaft area as suggested but in order to get to it I have to remove the lift arm off the side of the rock shaft and its not coming loose.
JD dealer is 150 miles away and cost $600 for 30 minutes and was not help.
Another tractor shop an hour away will look at it if I get it to them. Figures its the front pump...Says they fix lots of John Deeres.
