12. Grease the new gasket seals and insert them into
the grooves in both sides of all gear housings. Posi-
tion the first gear housing over the shaft end cover
and dowels. Tap it with a soft hammer until it rests
tightly against the shaft end cover. Be careful not to
pinch the gasket seal. Also be sure the large
rounded core is on the inlet side.
13. Assemble the channel seals into the grooves in the
thrust plates with the flat side of the seal facing away
from the thrust plate as shown below.
14. Gently slip the thrust plate through the gear housing
and into place on the shaft end cover. The channel
seal from step 13 should face the shaft end cover.
The relief groove in the plate should face the outlet
side of the pump.
15. Slide the driven gear through the housing and into
the bushing in the shaft end cover. Coat the steel
sleeve tool with grease. Place the lightly greased
drive shaft inside the sleeve and slide both through
the shaft end cover with a twisting motion until the
integral gear rests against the thrust plate. Avoid
damaging the double lip seal. Remove the steel
sleeve. Squirt clean oil over the gears.
