6. Torque the bolts in a criss-cross pattern in equal steps to 80 in.-lbs (9.04 N•m).
7. Lock the assembly in a vise and set up a dial indicator to read the end play. To measure the end play, rotate the shaft while
pushing in one direction, and set the dial indicator to 0. Now rotate the shaft and pull in the opposite direction while reading
the dial indicator. The end play should be 0.001 to 0.005 in. (0.025 to 0.127 mm). If the end play is incorrect, use different
shims to obtain the correct end play.
Shims available from the Service Parts Department:
• 0.020 in. (0.500 mm)
• 0.007 in. (0.177 mm)
• 0.005 in. (0.127 mm)
