Bobcat s70 bucket wont go up all the way when warm

I have a 2017 s70 when cold tractor pick up dirt and lifts perfectly once getting warm bucket will only lift of like half way struggling and I tried lifting it by hand helping it pick up and it would actually go up really wierd everything else works

Make sure your emergency lowering valve isn’t accidentally snagged on something. Right side of seat red handle.

Emergency lowering Is right in front of the middle of seat and it’s not snagged out i dont think it’s my hydraulic pump because it turns and drives good just dosent wanna get the bucket all the way up what’s really wierd is if u try with ur hand giving it a hand it will actually start going up more slowly

The loader pump is separate from the tandem drive pumps. You are obviously losing pressure as the oil warms up and thins. This usually points to the hydraulic gear pump. A proper test would involve pressure guage and also flow meter.

I checked the pump and it was a little off then what it is supposed to be do you think that is the cause I would have to change the hydraulic pump or could the problem be something else

Did you do a pressure test? Does the pressure drop as it warms up?

yes I pressure tested it yes drops down a little don’t know if that would mean pump is worn out or still somewhat good

Numbers? Make sure to test/ retest when warm.

Pretty simple to put a T-Tap in the line of the lift cylinder. It is either there or leaking off somewhere, unless the pump is worn out. How many hours on the unit, what type of oil in the unit. Before buying parts a new Hydraulic Filter installed and the old one cut open to check the pleated paper could reveal alot. Do all the tests first, and get help if your not sure how. Simon C

How’s your oil level?
