Hi all. Been gone a long time, but now I'm back in the Cub fixing business. I'm putting together a 149 from two basket-case tractors. I had the hydro trunnion welded up, and now I've got the tractor about 80% assembled. I want to check the hydro for leaks and adjust it for neutral. Problem is, when I disassembled the tractor, I drained the transmission. Now, I only have a gallon of hytran and can't get any more until the end of the week. Would it be ok to run the tractor with the rear wheels jacked up off the ground, and run the transmission forward and back to check for leaks and adjust the neutral position with only 1 gallon of Hytran in the system, or should I wait until I can pick up another gallon? Thanks.
