Does anyone know the dia. and thread pitch for the spindle back up nut (the nut on the back side on the spindle on a Logan 820. I think it’s to set the tension on the spindle bearings.). Or the same info for the spindle itself. S/N is 33206 Any help would be greatly appreciated!
Personally I would grab a mike out of my toolbox or, my calipers and
measure the OD, then get out my trusty thread pitch gauge and find the pitch...
Just sayin'...........That is if you have the part and tools available to do so........
Funny you should mention that. I have calipers but there is not an auto store or hardware store etc in this town that carries a thread gage. The older gentleman at Auto Zone said that they got rid of all the “old stuff” that we used to be able to find in any auto store. It was hard to find anyone that knew what a thread gage was. They wanted to sell me a feeler gage. So I ended up ordering one.
Yeah, a lot of older people here might be surprised at what can't be bought at so-called auto parts stores these days. The number of people around who can still overhaul/rebuild an engine, gearbox or front and rear axle is much smaller than it was even 20 years back. I don't recall right now what the tool was (and I still haven't found the one that I once had) but I got the same sort of answer recently from a guy who runs a parts store that mainly deals with garages, not the general public.
Here we go, (disclaimer) done with Mitutoyo digital guestimate caliper.
Spindle shaft threads OD = 1.288" and the OD of the threads (depth) = 1.253"
Thread pitch = 20 TPI
Nut ID = 1.237" with an OD of the spanner surface of 1.684"
And these are the measurements of the nut on the spindle shaft on the RIGHT SIDE of this picture...
