Re: [PSUBS-MAILIST] Kittredge Motor Housing help

[Jon Wallace <jonw@psubs.org>]

Thanks to everyone for the good advice.  I went out tonight armed with a 
propane torch (the kind used to solder copper pipe) and used it on the 
flat head screws holding the motor in the port thruster housing.  It was 
fairly chilly tonight at 45F and the heat worked great.  I applied heat 
to each screw for about 30 seconds and the screws came out with ease.  
No impact driver, just a good large hefty screwdriver that I finally 
found after a thorough search of the cellar (I knew it was there somewhere).

The electrical motor is sealed in its own metal housing and looks great, 
so I'm optimistic that internally it is in good enough condition to 
operate.  All I need is three of you guys to show up in my driveway so 
we can combine your car batteries into a 36v power source.  :)   Is this 
the first time that motor has been out of that housing in 32 years??  
Could be.

I was surprised to see that there was no support for the motor in the 
fore part of the housing.  The mounting plate that attaches to the dog 
ears welded inside the housing is the only means of support for the 
motor which weighs in at 25 pounds.  The four round head screws that 
hold the motor to the mounting plate were snug, but by no means tight.  
I didn't need any heat to unscrew them.  Maybe locktite on those when I 
reinstall the motor?
