Bolens H1502 with out 3 point power

[dstankus]

I have a Bolens H1502 which has a three point hitch. The hitch seems to raise but has almost no power at all. It seems to be able to raise the weight of the three point hitch arms, but almost nothing further. I can place my hand on the hitch and stop it from raising. Additionally, once the hitch stops raising after seeing a load, I can grab it and raise it by hand. The hitch will hold its poistion and not bleed down.

I removed and inspected the saftey (relief valve) the spring, ball, and adjustment is set to be nearly as firm as it can be.

I found a junction on the high pressure (smaller) steel line to see if the fluid was under high pressue and it seemed to drip out - but not squirt out dramatically.

I dont see a port along the steel line and am afraid to plug a gauge directly to the steel line without a relief valve - which would be bypassed if I disconnect the steel line to the control valve.

How can I further eliminate the possible casues without risking damaging the system?

Any help would be appreciated.

If you don't have a FEL that you could install a hyd gage, then you have to make up a tee fitting in the pressure line just after the pump, and add a male QD/Quick Disconnect. Just plug in the gage to test the pressure.

But it needs to be attached to a tee - right? You cant just send the pump into the gauge alone - like a dead end. I would have to remove and cut into the steel line and fabricate something - right?

If all you have is the 3pt, you have to cut and install a tee with a male QD.

The relief for your hyd system is at the 3pt valve.

Check the rockshaft housing over real good and see if you can find a test port (plug). Could be near the top side of the piston. If you have a parts manual see if you can find it in there.

I disconnected the inlet to the three point lift gear pump - attached is the picture of what I found. The plug was ment to be a screen I think - but in the bottom, where it looked like screen was glued on, there was a big chunk of chewed up metal from something, and the screen is gone - probably sucked into the pump line.

On my tractor the three point fluid is also used as gear case oil so this might have been something from the transmission - or something that has gone through the transmission most likely. I fished around in the gear case but didnt find any more pieces.

Obviously I need a new screen - and will keep trying to fish around in the gear case with a magnet to see if I can get any more pieces out.
