Questions: I bought a new pump for my L134 willys motor. The gear on the end is the wrong angle. Can I just change the gear or are the two different pumps for this motor?

Question By: mike archambault on Sep 19 2016 8:33 PM
For the 4-134 engine minimum safe pressure is 6 psi at idle. at 2000 rpm it should be 20 psi minimum. Normal oil pressure is 35 psi at 2000 rpm.

Question By: John vhal on Jun 14 2013 12:00 AM
Your oil pressure should always rise with more rpms...I would replace the gauge before you run it again to confirm you are not loosing pressure and doing damage to the engine.
