Installation Procedure
1. Connect the thrust pin (6) and the snap ring (5) to the chain
tensioner housing (7).
Notice
When connecting the thrust pin, push in the thrust pin far
enough so that it doesn’t protrude at the chain tensioner
housing. 4. Carefully unscrew the screw plug (1), and remove the seal
(2).
Notice
lFor the removal of screw plug, be careful that it can be
jumped out due to the force of compression spring.
lRemove the screw plug only when the seal and
compression spring are damaged.
5. Carefully remove the filler pin (3), compression spring (4),
snap ring (5), and the thrust pin (6).
6. Remove the chain tensioner housing (7) and the seal (8).
3. Insert the compression spring (4) with the filler pin (3) into
chain tensioner housing. 2. Install the chain tensioner housing (7), Thrust pin (6), snap
ring (5), and the seal (8).
