My crawler does not have the lifting pressure that i think it should have i have a 350 and when i put the hoe attachment on the 350 i can lift the rearend of the dozer off the ground but when i have it on my 450 it does not have the down pressure. does anybody have a suggestionn what may be wrong. I have replaced the filter in the tank and the one up next to the radiator are there any more filters anywhere

If its a Case 450C, have you checked the power beyond elbow oring seal? This oring seals off the pressure to the backhoe by not allow it to go to sump. That's what it kind of sounds like.

Oring is located on the outboard side of the loader valve.
