Cam Belt Automatic Tensioner Tool
A new method has been developed to compress automatic belt tensioners. New tool, 999 5456-2, is used to ensure that the automatic tensioner is not
damaged when compressing it prior to installation. A spring in the tool maintains a constant pressure on the tensioner plunger, pressing it into the
cylinder while keeping the force on the seal within permissible limits.
This new method replaces previous instructions to compress the tensioner directly in a vise.
Procedure
CAUTION: Do not use a vise to compress the tensioner.
Mount tool in vise. Place belt tensioner in tool and tighten tool center nut down fully.
When tensioner is fully compressed (i.e., hole in plunger is opposite hole in cylinder), insert locking pin through holes.
Unscrew center nut to remove tensioner from tool.
Inspect tensioner to ensure that no leakage is present.
