Outer Tub Assembly and Suspension 

The outer tub assembly is constructed in two halves 
and contains the wash basket. The bearing and seal 
assembly is part of the outer tub rear half. The outer 
tub assembly is supported by 2 suspension springs 
and 2 dampers. Each spring is located between the 
top of the tub assembly and a cabinet top brace, 
one on each side. Washer stabilization is achieved 
by the use of 2 dampers that are located between 
the bottom of the tub assembly and chassis, 1 on 
each side.

To remove the outer tub assembly:

WARNING: The outer tub assembly is heavy and 
requires two people to remove it from the washer 
cabinet. Care should be taken when removing and 
installing the outer tub assembly.
