I picked up another tradesman 1765 today. Reasonable price for condition. It needs a spindle nut, pins and the collar that holds them together. 2900340A is the part number I think, Ereplacements shows the spindle nut in the picture and Wilton parts shows it as a casing nut.
So after some more research 2900340A is the correct part #. The casing nut and spindle nut and end cap are one cast piece now. Have one on order. Both e-replacements and Wilton have old stock photos. This what the new ones look like. This one is for 1755.
It's all a lie. The part # 2900340a is the correct part # for the new Tradesman (made in Taiwan) Mine is a 2016 made in US. So I'm back on the hunt for parts or will part this one out.
I need the casing nut 2900340 (spindle nut) and pins
and the lock nut 2907780
