MW pump on M leaking

Posted by Chris Willy on May 15, 2005 at 14:57:36 from (66.231.13.42):

Hey guys, I need some help. I got an M&W pump from a guy for an M that mounts between the distributor and engine front cover to give me live hydraulics for my power steering and loader. I got the pump put on once and all plumbed up to the priority valve for the power steering giving it 3 gpm and the loader the rest of the oil. Well i found that it was leaking oil back into the crank case, so I took it all apart again and took the pump apart and found the shaft to be worn where it had rubbed against the seal. I took the shaft in to have it rebuilt by a machine shop and put new roller bearings and a new seal in the pump. I put it back on and worked good for 5 minutes then I thought I had the problem solved until I checked the oil level in my tank and found that it was empty, I cracked open the top petcock on the oil tank for the engine, and it was running out like crazy. Problem was still not solved. I need help. Does anyone have any idea why it is still leaking back into the crank case. I"m getting sick of taking it all apart time after time. I have it plumbed so that I have a small tank for the power steering unit feeding the pump oil then the pressure into the priority valve with 3 gpm going to the power steering unit and the rest going through just a looped 3/4" hose for now until I can get the loader mounted. Any ideas? Thanks alot guys.

Chris
