Jet 1236 Ps

The G9249 manual lists the carriage lead screw as M15, Part # 425. If your lead screw measures the same you may be in luck? I do know the change gears are the same, as I order a set for my Jet 1024P, the baby brother to your lathe.

Do you recall if you had to source 2 or 3 change gears as Grizzly shows a 30T, 32t and 46T. Not seeing any mention of the 46T on my Jet change gear label on the machine.
 
I purchased all 3. The 46T is for some less common thread pitches. But decided to get it, since Grizzly no longer sells the G9246, and I wasn't sure when they might no longer carry parts for it, ....and if I needed it later......

This chart is from the G9246.

There are a number of Manuals in the download section for the multiple variants of the Jet Lathe. Each of the manuals has info not necessarily in the others. I've put them all in a binder as a "master" manual.
