of the Thrust Base Housing and Thrust Base Plate. Then remove
the Thrust Base Plate.

Plate using the required quantity and thickness of shims to equal
the measured gap value rounded to the nearest .005". (See Note
below.)
8. Secure the assembly using the Cap Screws (piece 112) and top
off the lubricant using the grease fitting.
NOTE: Piece 108 is a shim set consisting of two .005" thick shims
and two .010" thick shims. This allows a shimming range from zero
to .030" in increments of .005".
