SPRING GP-RECOIL 1156401 - Caterpillar

Assembly of Rear Housing Group.
1. If bearing inner races were removed for replacement, press the new races into their respective bores in the rear bearing.2. Apply a film of sealant to the outer case of the output oil seal (figure 6-26, 10) and press it into its bore flush with the outer face of the housing.3. Thoroughly degrease the tapered bore of the output gear (figure 6-26, 7) and its mating surface on the output shaft (figure 6-26, 11) with a suitable solvent. All traces of grease of oil must be removed from the tapered surfaces. Dry the parts with clean of paper towels.
Do not chill the shaft nor heat the gear. Both must be at room temperature during assembly.
4. Determine output gear advance on shaft as follows: a. Measure and record the distance from the shoulder at the front of the shaft to the rear face of the snap ring groove (figure 9-1, dimension A).b. Place the output gear on the shaft and seat it using 100 to 200 lbs force.c. Measure and record the distance face of the gear (figure 9-1, dimension B).
Figure 9-1 : Determining output gear advance.d. Substract distance B (step c) from distance A (step a). The result obtained is the advance of the gear. This must be from .096 to .128 inch.e. Remove the gear from the shaft.5. Place the output shaft on the bench seating on the output flange face. Install the rear housing over the output shaft, seating it on suitable wooden blocks so that the output oil seal is further to the rear of the shaft than its normal position (refer to figure 9-2). Take care not to damage the seal by running it onto the radius at the front of the output flange.6. Install the rear bearing inner race onto the shaft and press it into position using special tool TD-300409 with items TD-300409/4 and 5 (see figure 9-2).
Figure 9-2 : Rear bearing inner race installation.7. Ensure that there are no traces of oil or grease on the output shaft taper or on the mating surface of the output gear. If necessary degrease the parts again as in paragraph 3. Install the gear onto the shaft and seat it firmly on the taper. Press the output gear into position using special tool TD-300409 and item TD-300409/4 (see figure 9-3).
Figure 9-3 : Installation of output gear.The gear should be positioned on the shaft so that the front face of the gear is flush with the rear face of the snap ring groove in the output shaft to within .002 inch. A force of 35 to 50 tons will be necessary to acheive this (see chart in section 12 of this manual).Remove the special tooling and install retaining snap ring (figure 6-26, 6).8. Press the front bearing inner race onto the end of the output shaft using special tools TD-300419 and 300420 (see figure 9-4). Use at least 6 tons force to ensure that the bearing is seating correctly.9. Install
