  1. Oh, I missed that in your post, sorry about that. As far as I know, the bushing allows tight, but free movement when the Reeves pulley moves during speed changes. Part of the issue with these pulleys seems that they basically seize up when they are unable to slide properly on the shaft, which then causes stress to the point of failure. I've seen other non-Delta solutions, but they have often had to machine parts to get them to fit. You might be able to get away without the bushing, but I wonder if the pulley would vibrate or wear out of round over time? Good luck, this issue frustrates a number of folks.
  2. @TSherm, 18 is listed as a bushing: https://www.toolpartsdirect.com/delta-46-715-14-quot-cast-iron-lathe.html Appears in stock, does that help?
  3. @TSherm, I didn't take the motor pulley apart so I'm not as familiar with that side of the pulley assembly. The plastic coated spring in your photo looks like something used to prevent grime and waste from dirtying up the motor shaft. I don't see in the attached Delta Lathe 46-715_TYPE_1 drawing I have for my lathe. Am I missing something?
  4. @TSherm, If I understand your question correctly then yes, you need the spring otherwise the Reeves pulley won't work. Do you have a photo of the problem?
  5. JaredBrashears, I uploaded some additional photos I took during the installation of my newly arrived 909945 Motor Pulley for Delta 46-715 Lathe. I hope these help you see what I did. Surprisingly, the replacement Reeves pulley is also no larger than the Grizzly replacement you ordered. I really think the belt benefits from the higher sidewalls on the original Delta pulley. When speed is adjusted to maximum, the belt rides really high on the motor pulley. The lathe shaft pulley is fine. I guess we'll see how that works out. The speed adjustment works fine once the motor shaft is polished with some fine emery paper and well greased. I live outside Seattle so heavy humidity all winter means I keep an eye on any bare metal for corrosion. Let me know if you have other questions.
  6. A long awaited update to my February 16, 2015 post above. After lots of time searching everywhere on the Internet, I came across Renovo Parts.com in Holly MI, who has been selling replacement parts for Delta. I'm assuming that demand finally reach a point where they had our infamous Reeves pulley assemble machined to original specifications. As seen by the photo, I ordered mine over a year and half ago, but just received my order for a 909945 Motor Pulley for Delta 46-715 Lathe. Sadly, my experience with the Grizzly replacement I mention above has been disappointing since the slightly smaller Grizzly Reeves pulley very quickly wears the drive belt at the maximum closed speed and leaves shredded rubber all over the inside of the motor box. I need to order a replacement belt now. Note I haven't installed the new Reeves pulley yet so I may have more to say later... JaredBrashears, I can send additional photos if you tell me what exactly you'd like beyond my photos in my earlier post. I posted a movie too.
  7. MikeM, I thought the same, but managed to get it free by using the spring-loaded force of the already broken other half of the pulley, but that would have been the next tool I would have bought, thanks! I was worried I might be going the wrong direction, but I found a copy of the exploded engineering assembly drawing. It was a pain, but once off some find metal shavings seemed to be the culprit. Once both halves of the pulley were off along with the spring and spring support ring, I ran the motor and cleaned and polished the shaft with increasingly finer emery cloth grits to get everything nice and bright. The other pulley half and supporting ring now move easily with little slop. For those keeping score at home with similar issues, I also learned the the motor pulley shaft was not parallel to the head stock pulley shaft, which I'm guess was one of the major issues as to why the Reeves pulley broke in the first place. Those two shafts must be aligned or else the motor pulley will experience uneven sideways forces, which would certainly contribute to breakage. I'm guessing that it was probably lifted and moved several times by the motor since it sticks out and is easily grasp. I loosened, aligned with a square and by eye the motor shaft and motor, then retightened the motor mount bolts on the inside of the head stock. Having disassembled, thoroughly cleaned, and then reassembled most of the head stock and pulleys I've come to the conclusion that simple maintenance (i.e. proper cleaning and lubrication) and the motor shaft alignment are extremely important to watch. For those with the Reeves pulley RPM speed control, I would inspect them! Now if the replacement arrives soon, I can report back on my presumed success… Adding a few photos and a note that I ordered a replacement Reeves pulley from the Grizzly G0462 - Wood Lathe With Digital Readout. The replacement pulley has the same motor shaft diameter, but is about ⅝ inch small outside diameter. It seems to work fine. Again, the important note is that the inner pulley must be able to slide to and fro on the motor shaft as it spins so the shaft must be smooth, polished, clean, and greased to operate properly. Regular maintenance and inspection is a must. I ordered Reference #9, Part Number P0462009, MOTOR PULLEY SET. A few photos of the setup: Lathe.mov
  8. I picked-up a Delta 46-715 lathe for almost free, but it also has a broken reeves pulley on the motor shaft like Brian Jenkins photographed above. I managed to find and order one online, but am having difficulty removing the old one. With the retaining ring and both set screws removed, it still fails to slip over the end of the motor shaft past where the retaining ring would be placed. Am I missing something or disassembling it incorrectly? Any advice is appreciated!
