MAINTENANCE MANUAL EXTRA 300LT
6 Detach belt from the alternator pulley.
7a (Bosch) Remove castle nuts (2 & 3) and pull bolts for re-
moval of the alternator from the attachment.
7b (Prestolite) Remove castle nut (7) and pull bolts (5 & 6)
for removal of the alternator from the attachment.
7c (Plane Power) Remove stop nut (10) and pull bolts (8 & 9)
for removal of the alternator from the attachment.
Installation
Refer to Figure 3.
NOTE When installing the Prestolite alternator, avoid unnec-
essary compression load at the mounting because this
may exceed the structural capability of the alternator
lugs. Thus do not torque castle nut (7, Figure 3) to the
standard value for M8 bolts. Hand tighten castle nut
(7) followed by max. one half (1/2) turn using a wrench
just enough to eliminate axial free play of the bolt (6)
and align nut and bolt for the clevis pin position. As a
final check, try to turn the bolt (6) at its head. If the
bolt (6) turns easily, it may be presumed to be tight-
ened correctly.
1 Install in reverse sequence of removal. Refer to Chapter 20-
10-03 for torque values of bolt connections.
2 Apply a proper tension to the drive belt by counter-clock-
wise rotating the alternator around bolt connection (3, 6 or
10, Figure 3).
3 Check tension of the drive belt and adjust if necessary per
Chapter 24-30-22.
