I'm finally getting to rebuilding the rest of the drive line on the H-42, I did the first half of the drive shaft, new u-joints, a few years ago and bought the parts for the other half so have that figured out.
That leaves the chain and both sprockets, Messick's site says to call, which I suppose I will but I'm not holding out much hope, the small sprocket is welded to a short shaft that has 2 bearings, replacing those too, then the big sprocket is bolted to the end of the auger and holds a bearing.
I just can't seem to find any good info, I took the parts to Tractor Supply and it seems the chain is a #40, they had the small gear, 18 teeth, but had a 2" dia. hole. Looking on Mcmaster Carr I think I'm looking for Ansi #40 chain sprockets? The hole dia. on the small sprocket is 5/8" need 3/4" suppose I could drill it out and have it welded onto the shaft in place of the old one?
The larger sprocket is 45 teeth and has a 23/32" hole, would my machine shop guy be able to cut that hole to 2", a bearing fits in it, and bore the 6 holes needed to bolt it to the end of the auger?
Chain #30, Large sprocket #29

Small sprocket #33, bearings #31, I think I have a specialty bearing place I can get those, auto parts store couldn't cross them.

Any hints or advise is greatly appreciated, Notice I am doing this in the summer, I'm learning...
Thanks,
