SPACER 1A0556 - Caterpillar

Illustration 11 g06297212
Typical Example
(D) Slide Hammer Puller
(E) Screw Tip
Use slide hammer puller (D) with screw tip (E) to thread into sleeve (B). Refer to Tooling Table 4 for applicable tooling.
Illustration 12 g06297221
Typical Example
(B) Sleeve
(E) Screw Tip
Once screw tip (E) is threaded into sleeve (B) then, use the slide hammer puller to remove sleeve (B) from the lube passage of the planet shaft.
Remove the mandrel head from the lube passage.Clean Planet Shaft Lube Passage Procedure
Illustration 13 g06297297
Typical Example
(C) Lube Passages
Ensure that lube passages (C) are clear of any obstructions.
During cleaning and handling, do not damage any of the shaft machined surfaces.
Personal injury can result from air pressure.Personal injury can result without following proper procedure. When using pressure air, wear a protective face shield and protective clothing.Maximum air pressure at the nozzle must be less than 205 kPa (30 psi) for cleaning purposes.
Use pressurized air to dry the shaft.Note: The tanks for dipping should be covered when parts are not being coated.
Dip shaft in SAE 30 TDTO (Transmission/ Drive Train Oil) to prevent rust or corrosion if inspection is not done immediately after cleaning. Spraying or brushing coating on does not sufficiently cover the surfaces of the shaft lube passages. Carefully store the parts in a clean container.Planet Shaft Plug Installation Procedure
Note: All Illustrations within the "Planet Shaft Plug Installation Procedure" are of planet shaft assembly (1) and can be applied to planet shaft assemblies (2), (3), and (4) due to similarity in design.
Use a suitable vice with non-marring v- blocks to secure the planet shaft.

Typical example of plug (5) installation tooling options.
(A) Mandrel Head
(B) Sleeve
(F) Stem
(G) Pneumatic Rivet Hand Tool
(H) Rivet Tool
(5) Plug

Typical example of plug (5) installation.
(A) Mandrel Head
(B) Sleeve
(1) Planet Shaft Assembly
(5) Plug
Ensuring that plug (5) is fully seated into lube passage (C) of the planet shaft, use a suitable rivet tool to install plug (C).Visual Surface Inspection Method
Visual Surface Inspection (VT) is a method for testing components for cracks without damaging the component. Refer to Table 5 for advantages and disadvantages and Table 6 for standards and requirements for these NDT methods.
Table 5
Crack Detection Methods Advantages vs. Disadvantages
Detection Method Advantages Disadvantages
Visual Surface Inspection (VT) - Least Expensive
- Detects most damaging defects.
- Immediate Results
- Minimum part preparation - Limited to surface-only defects.
- Requires inspectors to have broad knowledge of welding and fabrication in addition to Non-Destructive Testing (NDT).

Illustration of view through eye piece of a pocket microscope.
If necessary use a microscope with light for enhanced view and to measure the defects. Refer to Tooling Table 4 for the part numbers.Visual Surface Inspection (VT). VT is often the most cost-effective inspection method and requires little equipment as seen in Illustration16 or optional 17. Personnel performing VT
