Assemble balance weight (112) to non-drive end
of crankshaft rod journal with lock washers (114) and
cap screws (113). Heat the non-drive end bearing (111)
by immersing in oil heated to temperature of 350F (1
770C). Allow bearing to heat from live to ten minutes;
then, assemble (01 crankshaft journal with inner race
against shoulder of balance weight.
See Figure 6-7. Using rear pump cover and seal
tool (Table 2-1), assemble new oil seal (103), with seal
lip facing towards bearing, onto crankshaft (1 18). Install
four studs (I02) in oil pump inner cover (101) with short
threaded end in cover (101). Assemble cover (101) on
crankcase. Install pump rotor key (100) in (118) keyway.
Assemble oil pump rotor (98) over key (100) and
install pump blades (99). Remove cover and seal tool.
If end cover assembly (90) was disassembled,
press in one bushing (96) to a depth of 1.3201.330 inch
from face of boss on side of end cover (90), install o-ring
1t97), then press in the other bushing (96) to a depth of
0.780 0.790 inch from boss face. Position gasket (95)
on flange of end cover (90) and assemble end cover to
crankcase with oil relief valve boss located 90 from top,
facing compressor non-drive end and aligning studs
(102) with end cover holes. Secure end cover (95) to
crankcase with lock washers (92, 94) and screws (91,
93). Install oil pump outer cover (89). with chamfered
side of bore facing outward and drilled oil passage 111
the 12 oclock position over studs (102).
Assure that finished surface of o-ring seal is
against (facing inward) T-seal surface. Care
should be taken not to mar T-seal surface or
o-ring seal finished surface. (See Figure 6-
Install spring cup and spring of oil seal (88) over
crankshaft (] 18), place T-seal of oil seal (88) over
crankshaft (1l18) and into spring. Place o-ring seal of oil
seal (88) over crankshaft (118) with finished surface
inward. Assemble o-ring (97) on cover (84), assemble
cover (84) over crankshaft onto studs (102) and secure
with washers (86) and nuts (85).
