[TR] thread size of uprated Moss water pump shaft.

[Bob Labuz <yellowtr@adelphia.net>]

Hello,

Received a pump from Jeff at LBcar today but it did not have a nyloc nut 
supplied. Looked like 5/16 so I went to the hw bin and pulled out a 5/16 
18 and it would not fit. Tried a 5/16 24 no go.

I measured the thread with a gauge and it seems to be 20 TPI.

I emailed Jeff to get me the correct thread size and he replied 5/16 UNF 
which is 24 TPI. This shaft is not 24 TPI. It may be 5/16 but not 18 or 
24 tpi.

I went down to Lowes to check their metric HW and it seems to be a M8-1.25.

Can anyone help here? I dont want to install the pump without the 
correct nyloc nut for the pulley.

The moss part # for the pump is

-835-073 x 1 Total

Thanks,

Bob
