INSTALLATION—2MAD™ Seal
1. Install 2MAD™ seals (8) by securing seal with one
hand, sliding fingers under seal, and pulling seal onto
bucket boss (5) as shown.
2. Apply grease to pins and bores.
3. Align machine arm and link with bucket.
IMPORTANT: Prevent possible machine damage.
Using a larger diameter shim than recommended
does not allow 2MAD seal to seat properly.
2MAD seal must seat properly to keep
out dirt and debris.
4. 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.
