7) Inspect the appropriate cavities in the mounting
plate for wear and damage. Any nick or burr must be
remove by the use of an appropriate file, followed by
the use of 240 grit sandpaper. FIGuRE 27.

8) Apply the installation lubricant to the exterior surface
of the elastomeric mount to minimize damage when
pressing into the mounting disc. If the factory supplied
lubricant is not available, an acceptable alternative is
the use of common liquid soap.
Do not install an elastomeric mount without the use
of an approved lubricant. Installation without an
approved lubricant can produce tears in the mount,
resulting in substandard operational performance
and service life.
9) Support the elastomeric mount, 3/4 inch diameter
steel rod and mounting plate as depicted in FIGuRE
28. The section of 3/4 inch diameter steel rod is utilized
to thrust directly against the mount. The mounting
plate must be suspended from the arbor press to
allow the mount to clear when the pressing process is
completed. The section of 1-1/2 inch inside diameter
steel tubing can be utilized for this purpose.Center all
components on the mounting plate. using the arbor
press, apply a steady force in a straightline direction
to the mount until it fully penetrates the cavity in the
mounting disc. Do not attempt to push the elastomeric
mount through the mounting disc with excessive force.
Damage to the elastomeric mount will result.
10) Reassemble the mounting disc to the transmission
shaft.
11) Reassemble the mounting plate to the mounting
disc.
12) Reassemble the aluminum multi-accessory disc to
the mounting plate.
13) Check to determine that the replacement
elastomeric mounts allow for proper position of the
aluminum multi-accessory disc. If the elastomeric
mounts are not properly positioned, they will require
removal and reinstallation. The removal process can
produce tears and abrasions in the mount that will
require a new replacement.
