Alternator cover plate
by Karl von Salzen
Question: Does anyone know if this is
the correct p/n for the tin-seal-ring for an alternator
022-903-203?
Yes, IF you use it with the replacement
022 alt cover plate. The 021 plate used a different plastic seal
ring. If memory serves me: the 021 plastic ring has a raised edge
on it to fit in the hole. and is NLA. The 022 ring is flat and has
a locking 'tab' to hold it in place at the upper adjustment bolt.
The big hole is 2 different sizes between the 021 and 022. You
cannot mis-match the rings......
From the Bus Boys site:
K. 021-119-281U Alternator Coverplate,
Used 1972 to 1974
K. 022-119-281 Alternator Coverplate, New 1972 to
1979
Note: When using the 022-119-281 plate as
a replacement on 1972 to 1974 models, the plastic gasket for the
Alternator must be replaced with newer style - order
022-903-203.
