CHAIN
INSPECTION
1.
lnspect the chain elongation according to the following
procedure:
SST
09631
-
22000
-
71
(1) Since the SST measurement line varies with the chain type,
set the corresponding line on the chain as illustrated.
(2)
Check the number of the chain to be inspected, and
check the pin center position.
If the pin center is at the arrow mark on the chain gauge,
it is the limit.
Chain Link Pitch Standard (V.FV.FSV.QFV)
Note:
Perform measurement without removing the chain
from the vehicle.
lnspect elongation over the entire chain length since
it may be localized.
