12. Press the rear shaft bearing (22) into the endcap.
Install the bearing with letters facing out. Press until
bearing surface is 0.08 ±0.01 in (2 ±0.25 mm)
above endcap surface.
13. Install timing pin (23) into its bore in the endcap.
Install the pin with its groove facing toward or away
from the shaft. Press the pin until the end protrudes
0.12 ±0.01 in (3 ±0.25 mm) above endcap surface.
14. Install the valve plate (24) onto the endcap. Install
the valve plate with the yellow surface toward the
cylinder block. Align the slot in the valve plate with
the timing pin. Apply a liberal coat of assembly
grease to the endcap side of the valve plate to keep
it in place during installation.
15. Install the endcap (25) onto the housing with the
endcap screws (26). Check to ensure the endcap
will properly seat onto the housing without interfer-
ence. Improper assembly of the internal compo-
nents may prevent the endcap from seating
properly. Ensure the O-rings seat properly when
installing the endcap.
16. Using an 8 mm internal hex wrench, tighten the end-
cap screws. Tighten the screws in opposite corners
slowly and evenly to compress the servo spring and
properly seat the endcap. Torque endcap screws
35-45 ft.lbs. (47-61 Nm).
17. Before installing the shaft seal, ensure the shaft
turns smoothly with less than 120 in.lbs. (13.5 Nm)
of force. If the shaft does not turn smoothly within
the specified maximum force, disassemble and
check the unit.
