DO NOT BUY GRIZZLY G9249 PARTS TO REPLACE ENCO 92010/30 PARTS!
Old thread I know, but in case anyone is searching for Enco 92010 parts, I have this
one part-finding success to share.
Mine came to me with one tooth broken on a spur gear in the apron, the one that sticks out the back and meshes with the "rack" under the bed ways. The Enco part number for the spur gear is "92010 - 246", Name = "Gear"
I bought the corresponding part for the Grizz
G9249 — part # is "P9249336", name = "GEAR SHAFT 16 X 116T"
the Grizz part had one dimension that was too long. From the toothy part to where it necks down to the shaft diameter, it was maybe 4 mm longer than the Enco.
If I'd had a working lathe, I might have turned that pedestal length down to match the Enco, but I found it expedient to just reduce the height of the apron casting there by the needed amount. See second attachment. I just hand-filed it, no particular precision needed AFAIK. Also the Grizz part has sort of a spool shape, reduced diameter in the middle, and if I reduced the length of that by 4 mm, I'd have been getting into the smaller diameter part of the spool. Maybe that would have been fine too, but I can say my mod is 100% functional, with very little effort expended. I had it apart for cleaning anyway, which is how I found the broken tooth.
Strangely, the lathe seemed to work fine even with the broken tooth. I didn't test it much before buying and carting it home, but I did turn a 12" test bar to look for taper or any other problems that might show. I guess that spur gear must have more than one tooth engaged at all times, and the teeth on either side of the broken one were doing the work? Whatever crash caused the tooth to break seems to not have done any other damage. The rack that engages this gear seems completely fine.
Moral of the story, G9249 parts
might work, or be close enough to make a working part out of.
PS, my 92010 manual lists two variants, 10x24" and 12x36", but mine is 12x24". Most dimensions and parts are the same between the two, with the obvious difference being the head and tailstock are 1" taller on the 12" swing. About the only other difference I see is the 36" models have larger-diameter feed rod and leadscrew. Makes sense, since they have a longer span. And of course the corresponding parts in the apron such as the split nut have to match the feed/leadscrew diameters, so maybe the apron on the 36" is different in other ways too, to make room? And the pillow block (is that the word?) that holds the tail ends of the feed and leadscrew.
Strangely, I have two parts lists, one with Enco numbers and the other with no branding, probably from whatever factory actually makes them. Neither one has different part #s for the larger and smaller parts (leadscrew etc.) Even the headstock and tailstock are given the same part #, no indication of whether it's for the 10" or 12" swing. Just one of life's little mysteries.
