Overhaul
Outrigger Cylinders
Fig. 10-5: Outrigger Cylinder Assembly
(Ref. Fig. 10-4) The following procedure describes removal of the outrigger
cylinders.
1. Mount or support the cylinder vertically with the rod end down.
Hydraulic oil in cylinder will drain out during disassembly. Place a
suitable pan or tray under the cylinder.
2. Remove the differential pressure switch (Item 6) from the cylinder
manifold block.
Note: Early production models had the differential pressure switch installed on the
side of the control manifold block instead of where it is shown in Fig. 10-5.
These included S/N 101–154 for 1044C-54 models, S/N 101–103 for
10K-54 models and S/N 101–116 for 1044C-42 models with outriggers.
Note: Some early production models included also included an O-ring plug
(Item 5) in the control manifold block. This included S/N 133–154 for the
1044C-54 and S/N 101–103 for the 10K-54.
3. For models with an O-ring plug (Item 5), remove the plug.
