ASSEMBLY
Wear Ring
Apply Loctite 648 (P/N 420 899 788) on outer side
of wear ring before reassembly.
To install ring in housing, use a square steel plate of
approximately 180 × 180 mm × 6 mm thick (7 × 7 in
× 1/4 in) and a press.
Manually engage ring in housing making sure it is
equally inserted all around. Press ring until it seats
into bottom of housing.
If a press is not readily available, a piece of wood
such as a 2 × 4 in × 12 in long, can be used.
Manually engage ring in housing making sure it is
equally inserted all around. Place wood piece over
ring. Using a hammer, strike on wood to push ring.
Strike one side then rotate wood piece about 90° and
strike again. Frequently rotate wood piece so that
ring slides in evenly until it seats into bottom of
housing.
Seal and Needle Bearing
Bearings no. 20 and seal no. 19 will be properly
installed in housing using bearing/seal installer
tool (P/N 295 000 107).
