All of the ones Ive seen on the LP models the hyd reservior tank is usually mounted just like the other models, (gasoline / distillate) just in a different place. The plug that is in the back on yours would be the drain, and most of the time the plug that is in the lower middle front on yours is the vent which had a tube running to the side of the crankcase for ventilation. Im not all that familiar on how they did them on the LP models, but Im sure someone else on here will know more. I dont know everything....but I know enough to be dangerous.. :)

Alan, Your right! I found pictures of mine just before dismantel and there is a line from lower center of block (on distributor side)to the tank. My big question is does the Hyd tank use same oil as engine??
This tractor had not run for 30 yrs when I bought it and its been 60 yrs since I drove one Tony

Honestly, Im not sure how that would work as Im assuming unless there would be a check valve in the vent tube / line, I would think the oil would almost constantly "leak" into the engine, and even with a check valve then most of the crankcase venting would end up in the hyd tank wouldnt it? Anyone else have an idea? The engine oil is different than the Hydraulic oil. I believe the hydraulic oil was originally what they called "Type 55" which was eventually superceded by type A transmission fluid or equivilent (Dexron II & III, Im guessing). Do you have any pictures you can post before disassembly?

The line onto engine block by oil filter goes to the hyd. tank. Tony

That is interesting....most all the ones Ive ever seen (or paid attention to) were like John mentioned with the tank turned 90 degrees with the filler hole on the top front corner. I wonder why they changed them on the later ones, maybe the later LP tanks were slightly bigger? Anyone have an idea?
