6-7. VIBRATION DAMPER MAINTENANCE (Continued).
c. Visually inspect vibration damper for dents or
leaks around cracks or seam openings in hous-
ing. Replace damper if any sign of leaks or dents
d. Housing distortion check.
(1) Remove paint from vibration damper at
four points, each 90° apart.
(2) Measure depth of damper housing at each
point. If any of the points vary more than
0.002 inch (0.0508 mm), it is necessary to
e. Inspect the oil seal wear sleeve (1) visually for
wear, nicks, and scratches.
Use heat-resistant gloves when working with
a. Heat the crankshaft pulley (2) to approximately
400° F (205° C). Use a 388° F (197° C) ther-
momelt crayon (Appendix D, Item 54a) to de-
The marked surface will melt and become a
b. Install key (3) into keyway. Using heat-resistant
gloves, align the keyway with the key in the
crankshaft (4) and push the pulley (2) onto the
shaft (4) until it contacts the oil pump drive
c. Install retainer plate (6) and capscrews (7). Tor-
que capscrews to 125 ft-lbs (170 N.m).
d. Assemble vibration damper (8) to crankshaft
pulley (2) with hardened washers (9) and cap-
screws (10). Torque capscrews to 35 ft-lbs
e. Install power steering pump (paragraph 4-183).
f. Install compressor (paragraph 4-167).
g. Install alternator (paragraph 4-85).
h. Connect batteries.
