1990 510c late serial number 772 1990. 4x4 extandahoe, 2 issues maybe someone could help with. Will not engage to 2nd gear. Shifter goes into detent but no motion, no grinding. Runs out fine in other 3 gears.
Very slow hydraulics in all systems except steering. This unit has no reservoir except rear transaxle and all functions are tied together with various priority valves. Heavy chatter on bucket lift. All fluids new, filters and suction screens. I am suspicious of the de- stroke [stroke control valve #RE33524] valve on the front of the main pump. It has a solenoid - works same connected or disconnected. Or the priority valve under the unit. Pump makes pressure and you can use the hoe and bucket if light on the levers. Hate to buy a pump and find it still is slow. I am out in the mountains and no mechanics anywhere near that would know this machine. Any thoughts appreciated
