Instruction Sheet

SUBJECT: Improperly Assembled ZT-5400 Bypass

It has come to Hydro-Gear’s attention that the bypass on some ZT-5400s may be assembled

incorrectly. This can cause the transaxle to malfunction. Inspect the order of the transaxles by-

pass components. A correctly assembled bypass will have the seal, bypass rod, at washer, wave

washer and retaining ring installed in that order (see Figure 1). For example there have been

reports of the bypass assembled incorrectly with the at washer between the seal and the bypass

rod (see Figure 2).

To correct this the retaining ring and wave washer will need to be removed and set aside. In order

to keep oil loss to a minimum the bypass rod only needs to be partially removed. This will allow the

technician to work the at washer off the bypass rod. Once the at washer was been removed the

bypass rod can then be installed back into the transaxle. The at washer, wave washer and retain-

ing ring can then be installed (see Figure 1). Only a small amount of oil should be lost during this

procedure. If needed, top off the reservoir.
