john deere 50 lubrication requirements

larry Manual states capacities but nothing for weights spec' for engine trans/diff pto clutch,lift and hydralics
Mike Willhite Larry:
Lube requirements for 1951-1957 50 model John Deere.

Power Steering - if equipped - 5 wt SAE
Crankcase ------------------- 10 W 30 works well
transmission ----------------- 90 wt gear oil
Clutch drive pulley housing -- 90 wt gear oil
hydraulic Power lift system -- 30 Wt if you can find it, 10 W 30 will work.
The old tractors were designed bullet proof. No special oils were needed. We ran three of them and filled the crankcase with oil from a 55 gallon drum that had a hand pump to pump it into a qt. jar. Good clean oil will keep them running.
You may know this, maybe not, but never try to tighten the oil filter if it leaks. Drain the oil and put new gaskets on the oil filter. Over tightening will break the top out of the oil filter and it is a real pain to repair. Requires a complete tear-down of the engine to replace.
I hope the information helped you.
