Hello Dear Tech
I'm working on this C-5 1050-50 with John deer engine,
This engine has no oil pressure
I removed the Oil pressure sender and crank the engine no oil comes up,
After removing the oil filter and oil cooler still no oil comes up when I crank the engine.
Please I need your advice, do I have to check for any blockage or before i jump to the oil pump?
Or should I go to the oil pump directly.

The engine runs I didn't hear any rattling noise
I don't have any experience with this engine
Any advice help would be appreciated

Kind regards
Ram
