[HAM] Noisy upper rotor

[David Anderson]

Digital cameras are helpful for making sure you get parts back in the  
right place. Photo as you disassemble :-)

And, yes, it seems these days that more and more Leslies are reaching  
the point where they need motor service.

Ya gotta change the oil once every 40 years......

After doing all mine last summer, they run quietly and smoothly. The  
only problem I ran into was needing new spacer washers for a two- 
speed fast motor shaft. If these washers get chewed up, the fast  
motor shaft drops, eventually grinding the pulley on the screws  
underneath.

And while you're doing the motors, take the horn rotor bearing, soak  
it in naphtha or alcohol, let it dry (or blow out with compressed  
air) and re-oil. However, don't soak the older bearings with the  
integral pulley.
