Installation
Use the following procedure for preparing mounting
surfaces and mounting hardware.
1. The mounting surface of both the suspension and
the frame must be clean and dry. Use a cleaning
agent that does not leave a film after evaporation,
such as trichlorethylene, tetrachlorethylene, ace-
tone or lacquer thinner.
When using a cleaning agent, follow the manufac-
turer's instructions for use, proper ventilation
and/or use of breathing apparatus.

2. Inspect suspension and frame mounting surfaces
and spotfaces for flatness. Surface finish must not
exceed 250 (RMS) (medium tool cut). Surface
flatness must be within 0.010 in. (0.254 mm).
3. Clean and dry all capscrews, nuts and washers
as stated in Step 1, above.
NOTE: The use of dry threads in this application is
