Need Deutz Guys...

A friend gave me a F5L912 (1980) he had cut out of a truck. I have it sitting on the floor ready to start, but... where do you pour oil in it? I know there's none in there because it was laying on it's side with the torched-off dipstick tube on the bottom. I do not understand this oiling system. There's a external gear pump on the L.H. side of the motor. It sucks the oil from the sump, pushes it through a couple weird bypass valves operated by cables,(also torched off) and back to the sump. I do not see how the oil gets to the block. But it apparently does because there is a filter head on the R.R. corner of the block. What are these valves for? Thanks, Fritz
 
Not sure if it will be the same but on our tractors its on thr right front under/beside the injector pump there is a housing with a cap on it. Gear pump on right left side is the hydrulic pump on the tractors. engine pump is internal driven off the crankshalf hope this is some help
 
Not sure about your application but on the ag tractors the only cable operated valves divert oil to the cab for the heater.
 
Thank you for the information. I'm going to have to take a closer look at Deutz tractors...this project is getting more and more interesting. That valving makes perfect sense. The truck had to have a heater too. Guess they didn't have much trouble with the heater core plugging with that gear pump pushing it, eh? Thanks to All. Fritz
