I bought a 2wd Allis chalmers 8070 tractor a few years back, and I got nothing but only good things to say on this machine. great tractor, but I had a few questions.
My first question are the oil filters. I change the two slip/turn filters beside eachother but was told there is another filter ? (some bypass filter perhaps) I never did change that.
Question 2
Lately I have been having this tractor coming out of gear when the tractor is working relatively hard.
it is a 5 speed , with that power direct lever on the left side of the steering wheel. also sometimes when I shift into low on that lever the tractor comes out of gear?
I would appreciate any knowledge on this, as I really do like this tractor and it has been working very well and want to continue having this machine going

Engine oil bypass filter is above the starter on the left side of the engine. It is BIG compared to the other 2 engine oil filters. As far as "coming out of gear" goes.....unless your 1-2-3-4-5 lever or the High-Low-Park lever are moving to the neutral position on their own, it isn't coming out of gear. I'd suspect you might have a wet/oily torque limiter clutch disc and it's slipping under a hard pull. The next time it does this, quickly see if your power steering is sluggish or dead. If so, it's a slipping torque limiter. Shift down a gear to maybe get thru the Spring season.

The tractor comes out of gear in 5 high shifting down to low on power director as well as the power director at times will not switch to high , which I forgot to mention in my post . Also in 3 and 4th gears in high in the high power director at high revs I'll be working In field and the fast/slow selector lever will knock back into neutral
