DIAGNOSING TRANSMISSION PROBLEMS
Listed below are most of the service
complaints which would normally be
caused by a malfunctioning component
of the transmission assembly.
Oil leaks can be caused by faulty seals,
gaskets, 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
clothes load. The test that follows can be
used to isolate the problem.
A quick test of the efficiency of the spin
operation 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 spring cycle.
If the basket appears to reach full spin
with the weight, the machine compo-
nents are performing as intended. If the
basket does not attain full spin speed, the
torque test procedures as outlined in the
following paragraphs should be per-
formed to determine the problem.
The torque available to drive the spin
basket is determined by the amount of
drag or resistance presented by the tub
seal and spin bearing, deducted from the
input torque imparted to the transmission
housing assembly by the clutch assembly.
The Following Torque Tests Will Allow a
Problem in the Spin Drive Train to be
NOTE: Before starting these tests, the
washer should be operated in the agita-
tion cycle with hot water for about two
(2) minutes, and then for two (2) min-
utes in a spin cycle. This warms up the
transmission oil and the spin drive train
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.P.M.)
through a complete 360 degree cycle.
The reading should be between 18 and
25 inch pounds throughout the complete
360 degree rotation of the wrench.
