IIRC it is a "standard" 1/4" shaft pot. The tricky part is to get one
with the necessary angular rotation. I learned this recently in
replacing a joy stick speed control pot in a boom lift. Measure the
mechanical angular range of the bad one and also the resistance angular
range (you might get a reading if opened and cleaned with contact
cleaner). Then check catalog specs carefully to get a match in
rotation. Also check the shaft and thread protrusions, although some
washers and a hacksaw might be needed to get a fit. In the end, after
installing one that had insufficient mechanical range, I needed a $10
pot, not a Chinese $2. Digikey and Mouser have links to the detailed
data sheets. The Honeywell industrial controls pots might set you back
$30 if one is required.

Anyone know a source for the positioning pot in the G2800DXA. Something has
happened to the wiper and I do not get a reading from either end to the
wiper. I know it is a 500ohm pot.
Any help?
