Assembly notes:
•
Do not lubricate the spherical bushings with an oil or grease based product. It will attract dust and become
an abrasive paste rather than a lubricant. A small amount of dry lubricant such as graphite or PTFE (Tef-
flon®) can be used.
•
Tighten the screws that hold the lower axle bracket to the rear baffle to 30-40 in-lbs (3.5-4.5 Nm).
•
Tighten the shoulder screw to a torque of 45-50 in-lbs (6-7 Nm).

Test run the mower in a safe area. Check all of the safety features, and check the full range of drive speeds
before returning it to service. Do not put an unsafe mower into service.

It is false economy to save a few dollars on the bear-

steps used to remove it.
Lubricant: In the course of normal service, it should
not be necessary to replace the gear lube.
See Figure 4.48.
If there is reason to believe that the transmission
lubricant is contaminated, it can be drained and
replaced through the blue plug on the top of the
transmission houisng.
The transmission contains 1.0 fl.oz. (29.6ml.) of 85-
W140 gear lube (P/N: 737-3065, qt.).
Use a 5/32" (4mm) flat-nosed punch, or a similar size
pin to reinstall the blue plug.
