Sal, I am going to get up on my soap box again. You said ".....change it this weekend and clean out the system a bit with kerosene. I plan on running the 51 8N for a bit then drain it...but,..."
If you intend on running the hydraulic system for a bit with kerosene in the system, think about this for bit.The kerosene will do a GREAT job of loosening the years of acummulated dirt, grit, sand and muck at the bottom of the three compartments (tranny, hydra, and rear end). When you "run the system for a bit" (hydraulics, tranny etc) then ALL OF THIS 'acummulated dirt, grit, sand and muck' will also be going round and round in your systems. Thru the gears, in the hydraulic pump valves and pistons, lift cylinder, etc, etc, I ask - IS THIS REALLY WHAT YOU WANT TO DO? May I suggest an alternative. If the system has not been opened for a number of years then alot of "stuff" has accumulated. Purchase the gaskets for the two side inspection ports, two drain plugs, and the PTO shaft housing. Drain the system, remove the PTO shaft and the two inspection ports. Clean the chambers by hand from the PTO area and the inspection ports. You can use kerosene to hand flush all these areas. (IF THE ACCUMULATED STUFF IS REAL BAD, I WOULD EVEN REMOVE THE HYDRAULIC PUMP FOR CLEANING ALSO (need another gasket) I know it is a lot more work ( time and skinned knuckles) but the final results are much better and you don't have all this "stuff" running around in your system parts that you are TRYING TO PROTECT with clean lubricant. I guess my $1 and 2cents worth, Jim
