DRIVE CHAIN 0
GENERAL
Bombardier drive chains exist in 2 types, for prop-
er use refer to TECHNICAL DATA 10.
1. 1/2 in single
2. 3/8 in silent chain
SILENT CHAIN
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 according to width.
Refer to TECHNICAL DATA 10.
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.
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 because the chain pitch
has changed (increased) and will not properly
match the sprocket pitch, causing premature
wear.
NOTE: Refer to TECHNICAL DATA 10, for chain
length according to gear ratio of each specific ve-
hicle.
;
WARNING
Always ensure that the connecting link cir-
clip is in good condition and is properly se-
cured.
