63MackC85 Posted May 4, 2018 Share Posted May 4, 2018 Hello All, I recently purchased a 63 Mack C85 Fire Engine with a EN707 gas engine in it. It just started to leak oil from what appears to be a belt driven oil pump? on the back passenger side of the motor. When I crawled under it while it was running it looks to be coming from the shaft seal. Any idea where I could get one, or send the pump out to be re built. I'm in south eastern PA. I don't have any manuals for the truck and currently have a request in at the Mack museum but still have not received anything as of yet. Any help, or input is greatly appreciated.
