Plate sprockets are usually a small 5/8" hole
Hub weld-on sprockets are a 2" usually for X-series hubs

https://www.mdsofmi.com/product/finish-bore-sprocket-40fb18-1-12/

I think...
- X series - 2"
- W series - 1 5/8"
- V series - 1 1/8"

# Jack motor
m8 bolt pattern 45x70 mm
all the jacks are on 3/4" screws
electric jack is 3/4-6 

# Acme screws

THF is using a W1030

the MTD 917-04383 (ordered p/n GW-2675) gear is a... W1030D or W1030Q (double or quadruple thread)... I think double (D). Well, it's not exactly that part but it's 30 tooth, 10 pitch. 1" wide bore, 1 1/4" shaft, 1/4" keyway, .863 wide gear teeth (apparently centered on the boss).

MTD 917-04381 is a left-hand version of this same gear I think.
