1963 LKM Pair
Congratulations Kevin and Justin on a good save, as you can see by the serial #s these were built in early 1965 so the washer is a much improved version of the original 1963 machines. At some point in 1964 all BD washers got the beefed up HD transmission and 1/2 HP motors and WP finely got all the pot-metal parts out of the water system, except the two-way valve used on Suds-Saver models.
The dryer is a good durable design and blower belts are still available. The new belt will fit very tightly and on something this old I would make sure that the blower bearing is in good shape and well lubricated. This dryer uses a dual heater soft-heat system, it has both a 3,600 and 2,000 watt @ 240 volt heating elements. Both come on to produce 5,600 watts any time the dryer is in a heat portion of a cycle and once the exhaust housing near the blower reaches about 150 degrees the larger element cycles off the 3,600 watt element. If the clothes load is nearly dry or very small the 2,000 watt element will keep the 150 degree thermostat satisfied and the dryer will finish out the cycle on the gentler 2,000 watts of heat.
To shut off the dryer in the auto cycle there is an interesting adjustable thermostat on the top of the heater box [ you can see it in Kevin's picture, it has a flexible cable attached to a black knob on the rear of the dryer ] This adjustment is set at the factory but can be changed by the user or service person. It mainly needs to be changed to adjust for exhaust system length, supply voltage at the dryer 208-250 and the users preference for the degree of dryness they like. The thermostat works by sensing when the temperature at the top of the heater box DROPS DOWN in repose to the 3,600 watt element not being used and when the heater box temperature drops enough the contacts will close and turn on the timer motor and advance the timer to the cool-down period and the cycle will shut-off.
