7. Shim the boom as required using the shims (5) to
maintain a 0.10 in (2,5 mm) maximum gap (6)
between the boom mounting hub and the self
aligning bearing in the frame. If an additional shim is
required to maintain the maximum gap, the extra
shim MUST be inserted on the right side of the
boom.
8. Align the rod end of the right Lift/Lower cylinder with
the self-aligning bearing on the boom assembly.
Coat the entire Lift/Lower cylinder pin with anti-seize
compound. Insert the pin through the rod end of the
cylinder and the self-aligning bearing. Secure with
lock bolt. Repeat procedure with left Lift/Lower
cylinder.
9. Use a hoist or suitable support to position the right
side Slave cylinder to its original orientation onto the
lower cylinder mount. Coat the entire Slave cylinder
pin with anti-seize compound. Insert the pin through
the rod end of the cylinder and the self-aligning
bearing. Secure with lockbolt. Repeat procedure for
left side Slave cylinder.
10. Install the boom proximity sensor on the right side
mounting plate. With the boom properly shimmed,
position the boom assembly all the way to the right
side.
11. Insert the boom proximity sensor through the hole in
the right side mounting plate. Install the jam nut onto
the boom proximity sensor on the inside of the plate.
Adjust the inner and outer jam nuts on the sensor
until the gap (7) between the sensor and the boom is
0.12 in (3 mm). Torque the inside jam nut to 36 lb-in
(4,1 Nm), to hold the sensor in position.
12. Install the Extend and Retract tubes (8) to the inside
bulkhead fitting and the Extend/Retract cylinder.
13. Install the Extend and Retract tube clamp halves (9).
14. Uncap and connect the previously labeled hydraulic
hoses and attach to their appropriate cylinder
locations.
15. Install the Extend and Retract and Auxiliary (if
equipped) tube assemblies to their appropriate
bulkhead fittings. Secure with tube clamps.
