8011 Hydraulics

[allfoden]

Does the 8011 have two (2) hydraulic pumps as per the shop manual I have? I have a front loader that lifts at a good rate but appears not to have much lifting power. I don't have a guage to measure the hydraulic pressure but thought of just replacing the pump(s). Thank you.

Some, if they had assister rams, had an additional piston pump in the RH side of the clutch housing which only worked the assister ram. In my opinion it was a stupid system since it was lifting the ram all the time and then let down by the control valve when it got over hight, with the result that the hydraulics were rising and lowering all the time, which caused the assister ram seals to give out. Later models only had the one pump, in the LH side of the housing, and later models,8111 onwards , I believe, had a larger capacity pump.
The second gear pump in the RH side of the housing is for steering only.
The pump that works the Hi-lo, PTO and 4WD if fitted is on the back of the plate that the other pumps are on and can't be got at without splitting the tractor.
I think you had better check the hyd pressures on the rear coupling of the tractor and on the lift side of the loader spool valve, which should be the same, since there can be a port relief valve in some valve packs which can give trouble

Hi Fellas, i have an 8011 and recently i noticed that when i take my foot of the clutch it makes a slight knocking noise - clutch it and it goes away is there damage being caused by this or is this normal or nothing to be worrying about. The tractor was hard to get into gear when i got it first but i got that sorted and it is no problem now.

Usually they only rattle if the TA is in pos. hare and then only if its running slowly. The rattle is caused by slack in the gears probably, and all Crystals do it to a certain extent. I think you should go by the old adage " if it aint broke, Don't fix it ", remember you have possibly 25 years worth of wear in there !!
