7 Transmission Repair
7B Eaton 750 / 751
3. To aid in correct installation of the axle housings on
the transaxle, the transaxle and axle assemblies are
marked with an A and B (only necessary on Model
750). The B side of the transaxle must be assembled
first. There are two different brake shaft lengths that
are used in the axle housing assemblies. The shorter
shaft is always used in the A axle housing. The
longer shaft is always used in the B axle housing
assembly.
4. Apply a small amount of petroleum jelly to the lip of
the transaxle housing seal. Carefully install the longer
of the two brake shafts into the B side of the
transaxle housing.
NOTE: Make sure the lip of the transaxle seal is not
damaged during installation.
5. Engage the brake shaft splines into the parking brake
assembly by aligning and holding the inner disk and
thrust bearing with one hand, and rotating the brake
shaft slightly with the other hand. Install the other
brake shaft.
NOTE: If properly installed, both brake shafts should turn
independently and each shaft will rotate one brake disc.
