[PSUBS-MAILIST] Minn Kota 101 - thread spec

[Alan via Personal_Submersibles]

James,
why not take the pipe nipple out & fill with oil if it is protruding too far in to the
casing & inhibiting air from escaping? Alternatively unwind the nipple till it's just in
the housing & do it up when finished. Maybe turn the motor over to help get the air out. 
Also tip it on it's end in case air is trapped between the fixed magnets.
There was a good post on how to do all this, I think it was written by Greg.

If your oil compensating the motors and are going to add the wrap around tube\bladder as per Alecs Snoopy, I would suggest, adding a vent hole somewhere near the aft bearing.  With my setup, ive put the tube going around the motor and its all ok.  But, I just cannot get the last dregs of air out.  No matter what I do.  I suspect that its because the pipe nipple protrudes a mm or so into the casing and so will not allow the last bit of air out.  It really irritates me and I worry that the motor is not properly compensated.  So, I am going to make a modification to the motor like this pic.  I think this will work, the suspect bit is mating the plug against the slightly domed motor case.  I think a large rubber washer should seal it.   The i should be able to rotate the motor and remove the last dregs of air.  What do you think?

I put a digital caliper on this at it read 1.064-1.07 inches for the minor diameter.  I measured the threads and it is 18 threads per inch.    I looked in the machine handbook and the closest that comes is a 1-1/8  UNEF (Extra fine thread series).  The major and minor diameters for a 1-1/8" UNEF are 1.1250" and 1.0649"  respectively.
