INSTALLATION—Split O-Ring Seal
1. Apply grease to pins and bores.
2. Align machine arm and link with bucket.
IMPORTANT: Prevent possible machine damage.
Using a larger diameter shim than recommended
does not allow split O-ring seal to seat
properly. Split O-ring seal must seat properly
to keep out dirt and debris.
3. Measure bucket link and arm end play and add shims
(6) as necessary. If multiple shims are used, divide the
shims equally on each side of boom arm and bucket
link.
