Inspect the shaft for any signs of damage. Replace the shaft if a groove exists at the sealing land surface
that may let dirt into or hydraulic fluid out of the unit. If necessary, clean the sealing area with a non-
abrasive material. Inspect the input splines or keyway, block spines and output splines. Replace the shaft
if damaged. Ensure that the shaft's splines are straight and lubricate the shaft with a light coating of
hydraulic fluid.
