If a press is not readily available, a piece of wood
such as a 2 x 4 in x 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

After wear ring installation, install wear ring
screws no. 38. If the jet pump wasn't equipped
with screws, it is required to fit screws to wear
ring. Using their holes in jet pump housing as
a drilling guide, drill 4.5 mm (11/64 in) diameter
holes in wear ring.
CAUTION: Drill carefully paying attention
not to damage threads in jet pump housing.
Drilling holes prior to screw installation will
avoid wear ring deformation.
Install screws and torque to 6 N•m(53lbf•in).
