DIAGNOSING TRANSMISSION PROBLEMS

Listed below are most of the service com
plaints which would normally be caused by a
malfunctioning component of the transmis
sion assembly.

Oil Leaks

Oil leaks can be caused by faulty seals, gas
kets, or a loose fitting stud.

Slow Spin Speed

Slow spin speed can be caused by a binding
tub seal and/or bearing, brake rotor assembly

not disengaging properly, a slipping clutch
spring, or an off balance load. The test that

follows can be used to isolate the problem.

TORQUE TESTING

A quick test of the efficiency of the spin op

eration components can be made by placing
a 3 1/2 pound weight, such as a bag of sand,
in the washer basket and starting the machine
in the spin cycle. If the basket appears to reach

full spin with the weight, the machine com

ponents are performing as intended. If the
basket does not attain full spin speed, the

torque test procedures as outlined in the fol

lowing paragraphs should be performed to
determine the problem.

The torque available to drive the spin basket

is determined by the amount of drag or resis

tance presented by the tub seal and spin bear

ing, deducted from the input torque imparted

to the transmission housing assembly by the

clutch assembly.

The Following Torque Tests Will Allow a Prob

lem in the Spin Drive Train to be Pinpointed:

NOTE: Before starting these tests, the
washer should be operated in the agitation

cycle with hot water for about two (2) min
utes, and then for two (2) minutes in a spin
cycle. This warms up the transmission oil and
the spin drive train components.

Available Torque

Place a 1/2 inch socket and torque wrench on

the agitator retaining bolt.

Depress the safety spin switch to allow the

washer to operate in the spin cycle, then while

reading the torque allow the wrench to turn
slowly (about 6 R.RM.) through a complete 360
degree cycle. The reading should be between

18 and 25 inch pounds throughout the com

plete 360 degree rotation of the wrench.
