Pivot Bar

Pivot bars are not normally replaced in the service life of a tractor. The most common reasons for replacing a
pivot bar are:
• Damage caused by dropping the tractor (e.g. while loading or unloading from a truck), or collision with an
object.
• Damage caused by continued use after the axle bushings have deteriorated.
NOTE: Various hood and engine combinations may require using slightly different procedures than listed
below. The most common deviations will be on the muffler and muffler guard removal and the hood
pivot bracket removal. These instructions demonstrate removal of a stamped steel pivot used on most
riders. Procedures for replacing cast iron pivot bars are similar.

General Information

Continued operation with worn bearings will cause rapid
tire wear. If the bushing wears through completely, the
pivot bar will be damaged.
Replace any single-use fasteners (push-on caps and
cotter pins) with new ones on reassembly.
Lubricate all friction surfaces with grease such as MTD
P/N 737-0300A upon reassembly.
Tighten the steering arm clamp bolt to a torque of 200-
260 in-lb. (22.6 Nm-29.4 Nm). Replace the nylon ring lock
nut if it has lost its retaining capabilities.
