Bobcat has no lift power

[jena]

I have a bobcat I can tilt the bucket but no lift power. After warming up sometimes I can get the bucket to lift but not all the time. I have checked for leaks found none. Would just like to be pointed in the right direction please Any replies will be greatly appreciated

Put a hyd gage in the lift circuit and see what the pressure is.

When you move the spool, fluid is supposed to go somewhere, either the spool is not moving, or the fluid is sent somewhere else.

The shaft nut holding the piston on in the cyl could have come off, and the fluid is recirculating.

One of the lift cylinders has failed (blown seals, piston nut loose or broken hyd rod internally)

You probably have a bad disconnect. Internal failure is common. I have had several go bad and keep spares on hand.
You say your bucket curl works, so to check swap the hoses under the unit and try the lift. if the lift works you know the disconnect on the hose end is bad. The second check is to swap the end of the hoses where they connect to the cylinders. Be sure you depressurize before removing (with unit off move lever around through all positions).

Hope this helps.

PS be sure you note the brand and number of the disconnect when getting replacements. They are not generic.
