Can someone advise if known what the torque is on the 4020 hydraulic pump coupler drive pins (4) and 3/8 x 2 1/2 in. bolts holding the halves together? Also the 2- 3/8x 1 1/4 in. bolts clamping the coupler to the pump shaft?
could I put longer bolts in the coupler to the pump shaft with lock nuts installed? Would that be recommended?
I was curious about the pump. The shaft has no play in it. You can turn it with you hand although not real easy. not sure if that is normal or it should turn easily with the coupler removed.
