8. Install the lip seal in the end cap. See figure 4 for lip
orientation. Thread the end cap into the bearing housing
along with the outer bearing spacer collar. Tighten the
end cap. Lock the end cap in place with two radial
setscrews in the flange of the bearing housing.
9. See figure 7 and notes under “MeCHANiCAL
SeAL” on this page. Lubricate the outside diameter of
the seat gasket and install the stationary member of the
mechanical seal into the end of the bearing housing.
Note the shinny side of the seal seat faces out.
10. Slide the inner bearing spacer collar onto the shaft.
Thread the bearing housing assembly into the bracket.
11. Insert a length of hardwood or brass through either port
opening between the rotor teeth. This will keep the shaft
from turning when the lock nut is tightened. Install the
lock nut and tighten to 70-95 N•m on HLE pumps and
135-175 N•m on ATE and ALE pumps.
12. Adjust the pump end clearance as described in
“THruST beAriNg ADJuSTMeNT” on page 6.
13. Lubricate the grease fitting with multi-purpose grease,
NLGI #2.
