Bobcat 763 No lift when cold

[laurencen]

by chance the oil blowing past the seals in the lift cylinder? does it lift a load when it does work? you need to get hold of a hydraulic diagram and see if the lift system have a relief valve, this may need adjusting

This is an old thread but I have the same problem with a Bobcat 773. I changed the hydraulic oil and filter. It seems to be a solenoid valve that is not opening. As the OP stated, i can hear the pump and engine load up when I actuate the lift. Some valve is blocking it. If I let it warm up it works.

ATF for cold weather
Works great
Works good in summer to

One thing you might look at is the emergency lift lowering valve; it could have some effect on this. Seems like a likely suspect as drive and tilt work okay, and it's not part of the normal operating envelope.
