Grey fergie lift problem

[kamloops]

hi,

The lift arms on my grey fergie won’t lift much and when the do it will often bounce. I first wondered if it was simply the seals in the piston/ram but now I think maybe it could be the pump?

It’s quite expensive to repair the pump so I wondered if anyone can help me decide?

Copied and pasted this from another forum. Saves a bit of typing! Might help you.This was about a Fergie that would only lift a small load under high revs.........Worth checking as below but I think your pump will need rebuilt and has oil leaking past the pistons.

''Pull the right side access plate, engage the pto and start the engine. UNDER NO CONDITION PLACE YOUR HANDS INTO THE HYDRAULIC CPOMPARTMENT WITH THE ENGINE RUNNING! Using a flashlight, look up at the lift cylinder and see if you see a leak coming from it If so, the lift cylinder needs new rings , or the cylinder is cracked, etc. Look for a lot of turbulence near where the H shaped control fork enters the fluid. The relief valve may have some crud in it and is stuck open. Look at the corners of the pump. If there is a lot of turbulence there maybe a blown pump gasket. Look toward the front right corner of the hydraulic compartment. There is a supply tube that runs up to the lift cylinder. It has some O-rings the can leak. Now actuate the lift lever full up and see that the linkage moves the H shaped control fork. Finally shut the engine off and reach into the hydraulic compartment at the bottom of the control fork and see if you feel a "T" shaped piece which is what connects the control valve to the control fork. Make sure the arms of the "T" are in the sockets of the control fork. Also make sure the cross piece is connected to the control valve stem. You should be able to pull the control valve in and out easily and the total range of motion is about an inch. Some times crud get into the control sleeve and makes the valve hard to move''

The lift lever quadrant has sn adjustment
Loosen the bolts .. its on a slide ... were the assembly bolts to the lift cover

As Agrimax says really, if you have the pump out I would do the lift cylinder as well regardless, use a glaze buster to hone up the cylinder.
