When I turn the flow control valve under the seat it either does the cycling or it just hangs there.... the implement won't go down unless I readjust the flow control knob. No matter where the lift control lever is at. It seems as though when the 3 point lifts up, it stops where it should and...

Hi all.... I have a problem with my 3PH lift... with an implement on it you can raise it just fine but then it drops a bit and starts "cycling"... raise, lower, raise,lower.....etc. Shut the tractor off and it drops. FEL is working just fine, just the 3PH is giving me issues. It has about 2200...

Here's an update... Got the tractor split, hst pulled and opened up. The valve plates are scored, with one score on the pump side pretty deep, and the cylinders are scored too. I weighed some options and found a good used one that I am going to put on rather than order a new one and take a...

Well, I picked up the tractor from the shop. According to them the forward pressure is 1350, and the reverse pressure is 1550 psi. :mad: The charge pump is putting out 80psi. So, it is tractor splitting time. I already ordered a WSM from Messick's and it is supposed to be delivered today. I...

How do I check the charge pump pressure? I paid the shop to check the the rest. Can I check the charge pressure myself? All I could find on the charge pump were some allen head plugs.

Well, got good news and bad news.... the HST is pooched. Forward pressure is about 1500 psi, and reverse is about 1200 psi. Time for servicing. A friend that owns a hydraulic shop and machine shop said he can rebuild it for about $400.00 Hopefully that will solve the problems, if not the next...

Just wondering if anyone could tell me... if I take the hst oil filter off, bypass the clutch switch and crank the engine over, how much oil should pump out of the oil filter plate? I tried it but I am not sure if it should actually flow, squirt, or what...

Well,I have changed the filter, same ole problem.... it is definetly not the clutch because I can see the shaft spinning freely ..... I think it might be the charge pump... I tried a few different things though.... when traveling and I release the pedal, it jumps as it is trying to slow down...

I hear ya on that. Last night I went and did some more testing on the tractor and I found that when the tractor loses drive, the FEL still works even with the hst pedal all the way down. So that would pretty much eliminate the clutch possibility wouldn't it? It just sure feels like it is a...

Well, I got the tractor out and went stright for the dirt pile... once i started into it I tried to spin the tires and it just stalled.... but I did notice that when it stalled, the rpm went back to normal with the pedal down like it was bypassing or like i didnt even have the pedal pushed down...

I don't know... I haven't actually done that..Last weekend I did some digging around a stump using the backhoe and then when I went to move it, it just sat there in the dirt. I had to use the hoe to get it out of the hole that it was in because of the ground being soft, and when I would try to...

Hi all... new to the forum here....wonderful site.. I have a B1750hst that has been giving me fits and I can't seem to figure out what the deal is. It will work like a hoss and run perfectly fine for about 20 minutes and then it loses drive. I have checked with the local dealers here and they...
