1911 Otis Elevator worm drive gearbox specs.greenspun.com : LUSENET : Elevator Problem Discussion : One Thread
Yeah, it's "vintage" but still works like a champ. Anyway, we are looking to find what the "baseline" tolerance spec. is for these gearboxes so we can determine the wear and tear that time has put on it. The info is OTIS machine #272524, No 4-H, Feb 1911. If anyone has some diagrams or engineering specs on these gearboxes please let us know. Kinda hard to say they need rebuilt if we don't have a starting point to determine what is "new" and what is "worn out". Thanks in advance!

Hi There, I dont know if even Otis still has that info but I am sure that TITAN machine shop does. There are in New Jersy or NY, It might be cheaper to put a new machine in or better yet to find a used machine. Jim

By the time you get done with researching the parts, a machine shop, your mechanic and helpers time, you'd be better to just make a call to Hollister-Whitney and replace the damn thing. I went through all that on an old OTIS machine, we bought a new HW machine cheaper than it would have cost to replace the ring and worm.
Besides, unless your customer is really "hung up" on that old OTIS, they will be much happier and it's easier to get them to spend $10K for a machine and ropes and have NEW.
