PLUG-RUBBER 5416183 - Caterpillar

28. Put clean hydraulic oil on the lip of lip-type seal (38). Install shaft (34) in the travel motor body with a press. Rotate the shaft slowly during installation, making sure it does not bind. Be sure the bearing on the shaft makes contact with the counterbore in the body.
The locating pin on each key (32) is not centered. To prevent damage to barrel assembly (23) during assembly of the travel motor, the keys must be installed as shown in the illustration. Also, the keys must be installed in their original locations in the travel motor body.
29. Install two keys (32) in the travel motor body as shown. 30. Install cam plate (30) in the travel motor body in its original position. Be sure the machined cutouts in the cam plate engage with the keys. 31. Install nine springs (29) in the barrel. Install spacer (28) and retainer (27) on the barrel. 32. Install piston shoe assemblies (25) in their original bores in shoe retainer (24).33. Put clean hydraulic oil in the bores of the barrel and on piston shoe assemblies (25). Install the piston shoe assemblies with the shoe retainer in their original bores in barrel (26).
Prior to installing barrel assembly (23), be sure cam plate (30) is correctly engaged on keys (32). When the travel motor body is tilted to allow installation of barrel assembly (23), cam plate (30) can slide off of keys (32). The remainder of the travel motor can be assembled with the cam plate out of position, however extensive parts damaged will occur during the remaining assembly procedure. Use the procedure which follows to prevent parts damage.
34. Put clean hydraulic oil on the sliding surfaces of the cam plate, the piston shoe assemblies and on the splined shaft of the motor. 35. Route a piece of strong string through one of the openings for the cam plate tension adjusters, over the sliding surface of cam plate (30), and out the other opening for the cam plate tension adjusters. Hold the string tight to keep cam plate (30) properly engaged with keys (32). While keeping the string tight, put the travel motor body on its side. Do not release the tension on the string at this time. Install barrel assembly (23) on the shaft as a unit. Pull the string out of the travel motor body. It may be necessary to pull the barrel assembly and piston shoe assemblies away from the cam plate a small amount to release the string. 36. Check the condition of the O-ring seal and the back-up ring used on piston guide (19). If the seal or ring are worn or damaged, use new parts for replacement. Install O-ring seal (21) and back-up ring (22) on piston guide (19) as shown. 37. Put the travel motor body in a vertical position.38. Put clean hydraulic oil on three friction plates and three steel plates (20). Install the plates in alternating order in the travel motor body. Start with
