28) Position either of the two 27 tooth LoMax helical gears inside the case and
pass the rear output shaft through the case and bore of the gear. Be sure
to install the stock thrust washer onto the shaft in a position above the
helical gear. Place the case in a vertical press and press the tapered roller
bearing # 25880 onto the shaft. The bearing should stop as it contacts the
thrust washer (Fig. 27). Verify the helical gear can turn free after the press
operation is completed.

29) Position the second 27 tooth LoMax helical gear inside the case and pass the
front output shaft through the case into the bore of the gear. Place the
case in a vertical press and press the tapered roller bearing # 86649 onto
the shaft (under the gear). The bearing should stop as it contacts the
shoulder on the shaft (Fig. 28). During the press procedure, support the
bearing properly so not to damage the cage around the rollers. Verify the
helical gear can turn free after the press operation is completed.
