1972 WP Portable Drayer
Cool little dryer Louie I remember these well, The lint filter may be NLA if it isn't it may be expensive, I may have one if you cannot find one.
The grove in the white idler pulley was worn there by the belt, it means the bearing is not in good shape, you need a new IP.
The blower rubbing on the rear housing is caused by the motor mounting brackets being bent so the motor is back too far, the motor mounting bracket is easy to straighten when you have the machine apart.
This dryer may still have the 240 volt 5600 watt heater element in it, on WPs early 120 volt portables they just put the regular 240V-5600 Watt elements in instead of making a special 120V 1400 watt element just for the 120 volt portable dryers. If you run the 240V 5600 Watt element on 120Vs you get exactly 1400 watts of heat, but the element runs very cool [ it will never get red hot ] this is why they did not need the asbestos insulation under it and best of all the 5600 watt element should have a life expectancy of about 3000 years of normal use.
This dryer with the older style door hinges will allow you to add a window door which I have several of if you want to add this valuable feature, unfortunately I do not have have a brown door but they are easy to paint, John.
