The tool listed is necessary for the following procedure:
MEL1420 – Carrier Seal Tool
Remove the hydrostatic motor. (See Removal And Installation on Page 30-20-1.)
The motor carrier seal (Item 1) [Figure 30-20-49] is located on the outside of the motor carrier shaft.
Drill a.125 inch (3 mm) hole in the motor carrier seal [Figure 30-20-50].
Use a slide hammer to remove the seal from the motor carrier shaft [Figure 30-20-51].
Installation: Install a new seal over the motor carrier shaft [Figure 30-20-52].
Installation: Install MEL1420 Carrier Seal Tool over the carrier seal [Figure 30-20-53].
Hit the tool with a hammer until the seal is fully seated on the carrier shaft [Figure 30-20-53].
Photo [Figure 30-20-54] shows the motor carrier seal correctly installed.
NOTE: Before reinstalling the hydrostatic motor, check the plug (Item 1) [Figure 30-20-54]
located in the center of the carrier shaft for tightness. If the plug becomes loosened, case drain lubrication oil from the hydrostatic motor can leak into the chaincase.
