SENSOR GP-PRESSURE 1414122 - Caterpillar

Typical Examplea. Fasten Tool (D) and a hoist to main housing (25) as shown. Install the main housing on the motor housing. b. Using a suitable press and spacer, apply a load of 4000 kg (8820 lb) on bearing (28).c. Rotate the main housing to seat the bearings.d. Reduce the load on bearing (28) to 1000 100 kg (2200 220 lb).e. With the load still on bearing (28), measure the distance between the top face of the motor housing and the inner race of bearing (28) with a depth micrometer. Take this measurement in several locations around the bearing. Find the average of the dimensions measured, and record it. Call this dimension (Y). f. Using a depth micrometer, measure the step height of gear (23) at several locations around the gear. Find the average of the dimensions measured, and record it. Call it dimension (X).g. Determine the correct thickness of the shim pack [made up of shims (24)] to be used between the motor housing and gear (23). The shim pack thickness is equal to dimension (Y) - (X) 0.05 mm (.002 in). If two shims are required, install the thinner shim next to gear (23) when it is installed.28. Remove the main housing from the motor housing.
See the topic "Assembly And Installation Of Conventional Duo-Cone Seals" in this module.
The rubber seals and all surfaces that make contact with the seals must be clean and dry. After installation of the seals, put clean SAE 30 oil on the contact surfaces of the metal seals. 29. Using Tool (E), install Duo Cone seal (27) in the main housing. 30. Using Tool (E), install Duo-Cone (26) seal in the motor housing.
Do not scratch or damage the Duo-Cone seals in the main housing or the motor housing during assembly of these two components. After installation of the main housing on the motor housing, there will be a small gap between the components. The gap is caused by the Duo-Cone seals and will and will be eliminated during installation of gear (23).
Typical Example31. Fasten Tool (D) and a hoist to main housing (25) as shown. Install the main housing on the motor housing. 32. Apply 5P-3931 Anti-Seize Compound to the four pins in gear (23).33. Install shims (24) determined in Steps 27a through 27g and gear (23) in its original
