Minneapolis Model UTU Heads

JT is a JT or ZT part #. Is only numbers used.

Thank you. I think I will just replace it with either a newer style lock nut, or one of the same design with a washer. I was able to thread one of the nuts used to hold the brake drum on with. I will use that to get something new to replace the other.

I have a bit of information to pass on here. The following part numbers for the nut and washer to secure the clutch on UT are as follows:

Nut Original Part Number = JT 2252.
New Part Number = 1011223
So far that number is coming up as either Obsolete or discontinued

Washer Original Part Number JT 2253 (no change in number)
This was found to be available at Schmitt and Sons in Winfield KS. However it too has been discontinued. I will try and order one to see it fhis works.

I do know for certain that the thread size for the shaft is 1 and 1/4" 12 TPI count. This is considered a National Fine thread for this shaft I was able to find a nut that will work to help press the outer clutch plate onto the shaft for installation. It is too thick to run but I am going to search for some form of thin type locking not instead. Axle nuts have been recommended however most of those are castellated and need a pin.

Get a castle nut or similar and slice it to size. 1011223 is not a MM part #.There is no cross. Should be easy to find on a scrap one. Hundreds of old U's in boneyard.
