We have this old Whirlpool belt drive washer. I think it is a 1977. The
date code on the motor (presumably a GE) says 437 so I peg that as the
43rd week of 1977, though I can be wrong...

Anyway, to describe the events leading up to the failure, I did one load
of clothes and noticed that the final drain, before spin, took an extra
long time. At the next load, during the final drain, the laundry room
filled with smoke coming from the washer. The clothes were still wet, I
had to bail the basket, etc.

This washer is Whirlpool Model LAB4900, a case where the controls are
located on the very front of the chassis rather than on a panel at the
rear, belt drive, three port pump that recirculates water.

I removed the motor for inspection. It appears to be good, no melted
wires or any sense of over-current. The motor has a centrifugal switch
and seems to lack a start capacitor; the part number is FSP 362947 which
does not cross to anything on the web.

After removing the motor I noticed the condition of the belt because it
was very slack and could naturally conform to its condition. It
exhibited wear down to the plys over an area and also a 'bump' or kink
in the spring of it which indicates a jammed overheating of the belt. I
am going to replace the belt.

The pump seems to rotate freely. I have exercised the unit in wash,
spin, and drain and it now seems to work again so I think that it was
just the belt that generated the smoke.

My questions regarding this oldie a

1) The pump has clips. Should I open the pump up and see what is in
there. I suspect that a 'shag' carpet may have introduced too many fibers.


2) What is the deal with the motor and the centrifugal switch. Will I be
able to find another? The speeds are 1725/1140 RPM. If it is the motor
giving out at the end of the wash, can I replace it with an Emerson or
GE belt drive rated?


3) The unit has spent some time on its side and oil has leaked out of
the transmission. What if I drill a hole in the case, fill with oil and
seal hole with a pop rivet?

Thanks in advance for all your help!
