DRIVE CHAIN 9
GENERAL
Bombardier drive chains exist in 2 types, for prop-
er use refer to TECHNICAL DATA 09-03.
1. 1/2 in single
2. 3/8 in silent chain
SILENT CHAIN
For 1997 there are 2 types of silent chain. One is
11-plate wide and the other (stronger) is 13-plate
wide. Do not interchange sprockets. Fit chain on
sprockets to make sure using right ones accord-
ing to width. Refer to TECHNICAL DATA 09-03.
NOTE : No work (separation, lengthening)
can be done on the silent chain type.
CHAIN ATTACHMENT
When joining chain ends, the open end of the cir-
clip must be on opposite side of chain rotation.
The circlip should also be facing the outer side of
chaincase.
WARNING : Always ensure that the con-
necting link circlip is in good condition
and is properly secured.
TYPICAL
1. Rotation
CHAIN SEPARATION
When separating an endless chain, always use a
chain bearing pin extractor. Also, make sure to re-
move one complete link.
NOTE : Chain connecting link should only be
used to lengthen or shorten a chain when
changing the number of teeth of sprocket(s). A
stretched chain must never be shortened be-
cause the chain pitch has changed (increased) and
will not properly match the sprocket pitch, caus-
ing premature wear.
NOTE : Refer to TECHNICAL DATA 09-03,
for chain length according to gear ratio of
each specific vehicle.
