Fan assembly
No specific servicing is required for fan assembly. Occasionally
check bearings for proper sliding, replace if necessary.
Aligning fan pulley to engine pulley
(Fig.1 and Fig. 3)
Both pulleys should be thoroughly aligned. Fit a straight rod on the
bigger pulley face and ensure it is aligned to that of the other
pulley.
If not, remove or add shims to the crankshaft pulley in the position
indicated by the arrow B (see figure 5).
Any extra shims are to be positioned under the heads of the pulley
retaining bolts.
Aligning alternator pulley to engine pulley (Fig.5)
Fit the alternator and measure the amount of misalignment using
a straightedge across the face of the crankshaft pulley.
Fit shims of this value between the pulley and the support in
position A.
