Installation
Outriggers (Ref. Fig. 10-2) The following procedure describes installation of the
outrigger.
1. If the bushing and shaft assembly were removed,
a. Install a bushing (Item 8) in the outrigger support plate. Make sure
the front edge of the bushing is flush with the edge of the support
plate.
b. Install the shaft assembly (Item 17) on the bushing, making sure
the port for a grease fitting is on the rights side of the machine.
c. Install a grease fitting (Item 21) on the shaft assembly. Torque the
grease fitting to 1.5–3 turns past finger tight. Install a grease fitting
cover (Item 22) on the grease fitting.
2. With the boom raised and fully supported, use sling(s), crane or other
suitable means of support to position the outrigger until it can be slid
onto the shaft assembly (Item 17).
