Subject: Re: [PSUBS-MAILIST] Kittredge Motor Housing help
Vance, you're never going to qualify for the "PSUBS Cold Weather
Overhaul" patch under those Florida conditions.
A nippy 35F tonight. I was forgetting tools on purpose just so I
could go inside to warm up. :) In another month it will be warmer
in my refrigerator than outside and I'll be fondly recalling how
nice it was when I pulled those motors out.
In any event, I picked up an impact driver and it worked like
magic. Three blows and the screw was turning easily. The starboard
side motor backing plate was much tighter than the port side and I
had to wrestle it a little bit to extract it from the housing.
Disconnected the wires and brought it inside. This one has a
Honeywell tag on it instead of Advance Motor Operation. Given the
difference inside this motor housing compared to the port side, I'd
have to guess the port side flooded and when they went for the
replacement motor Honeywell had already transferred their motor
division to Advance Motor Operation.
Since I was having good luck I decided to tackle the big motor in
the back of the sub but was unsuccessful. I removed the prop and
mechanical seal, but I won't be able to use my crowbar technique
because the vanes on the kort nozzle are much thinner than the
forward motors and won't take the pressure that needs to be applied
without bending the vanes. I'm going to have to either find a good
chain wrench to wrap around the tank head, or get some 1/4 inch
scrap metal and weld some tabs onto the tank head temporarily so I
can use it for leverage. I suspect a bearing is gone on the rear
motor since when I turn the propeller shaft I can hear some awkward
gritty sound. There was a lot of dirt between the mechanical seals
so that housing may have flooded at some point too. If so, its
probably pretty rusty in there and the tank head is going to be
difficult to get off. I may be done for the season depending upon
the weather but I'm glad I at least got the two forward motors off.
