Walker MTGHS 1995 Serial #23429. as stated above when stopping the machine with the FSC the machine will bear to the right.
Notes: at some time prior to this serial number the jackshaft was changed and then at a later date, just the ground drive pulley on the jackshaft to hydros was changed, this was gleaned from walker manual 8895-1 under unique parts for the 20 and 25 hp models
I have used the ground drive aa45 belt which squelled like crazy and the 3v micro which also had some slippage (one side stronger than the other) I now have the correct belt on the ground drive which is a 7235 a double cogged belt.
The machine has been lubed thourghly, there are no leaks on either hydro shaft or control arms, the hydro oil was changed using straight 30w and air bled by rotating the hydro pulley. The machine was then run under a light load with the blades not engaged for several minutes, allowed to sit overnight, air bled once again and the cups filled to cold line.
The linkage including the springs on the control rods, the return spring on the handles, washers and ball joints are all in place and functioning properly.
The machine tracks straight on pavement, the drive tires are inflated to 15psi, the deck tires and rear tire also have proper inflation.
Note; It is understood that when going to neutral with the FSC that the right hydro goes into neutral before the left hydro, thus turning the machine to the right.
WHAT IS MY PROBLEM?
Thanks to all in advance
