i read a post on here once that someone put a u shape bend in the suction line of their charge pump and it fixed the problem they had with their machine.which was- all the oil back draining out of the pump thus making it have to prime itself when they started the machine--
the last couple times i started my machine and after a 5 minute warm up at idle. when i put in reverse to back up(low gear-low range)i get no responce even if i goose it--i'd say maybe half throttle-- i tried low forward--same thing-- tried putting it in netural and revving up the motor to prime the pump-(if thats whats going on) still no responce.. next i put it back in forward low and really stepped on it--i'd say 3/4 -throttle and that made the machine kinda try-but then nothing---went to reverse low--revved it up about the same , and it shifted into reverse..from that point on it worked fine. i used the machine for about 20 minutes and shut it down---the oil level is good in the transmission---it was changed out a couple weeks ago-and refilled with 32wt hydraulic oil--and thats because thats what came out of it when the oil was changed.
my machine has a u-shaped pipe on the suction side of the charge pump--to keep oil in the pump (i presume) so i am wondering if i'm getting air in the pump somehow that would let the oil be siphoned out of the pump--or should i be looking at something else that might be the problem?
thanks to one and all--
