I figured I best post in the Case forum for this problem. I bought a Case 440 recently and the 3pt. hitch won"t lift. The hyd. pump makes a lot of noise (cavitation?) and when I cracked open a fitting to try and bleed the system all I got was a "burp" or two and lots of foamy hyd. oil. Any suggestion"s on what to look for? Do the tranny and the hyd. system share the same fluid resevoir?

Dave,
It sounds like you are low on hydraulic fluid, the transmission and the hydraulic system do NOT share the same resevoir.
The transmission/transaxle has a dipstick behind the 4 speed shifter on top of the housing on the left, it is a large hexshaped plug. The transaxle uses 80/90 gearlube.
The Hydraulic reservoir is under the instrument panel on the triple range shifter cover it is usually a plug that thakes a 1/2" square drive ratchet.Use Tractor hydraulic oil in the hydraulic system. You should not have to bleed the system.
Hopr this helps

You might want to double check your manual. I believe most of the hydraulic systems on these units used 30W motor oil. Hydraulic oil will foam.
