on the other hand...

I also purchased two drive belts for my Jet 1236 because the last one I purchased (from an independent source, below) shredded in about a year of little use. The original lasted 15 years. I suspect the usual poor quality replacement parts we see in automotive and other venues.

I purchased one from eReplacementParts.com for $19+

I purchased a backup from Jet for $19 when I bought the cap.

The first belt just came in the mail today. The real cardboard packaging sleeve has a totally different part number printed directly on it. The Jet/Wilton number was on a small sticky label pasted on the back to indicate that this is actually the part I ordered.

I just did an "equivalence" check on the real package number and found that I could have bought it from V belt Global Supply LLC for $1.21. Live and learn.

So for you Jet 1236 owners out there, your Reeves drive belt is actually a 3L230, also sold as a Gates Truflex 1230. A number of suppliers have them listed for under $5.

The one that failed after a year was from eReplacementParts. Now you see why I bought a spare.

The cap from Jet was $22.55 + tax + s/h, which I suppose will seem fair until I get a look at the real part number and look for the equivalent. :-p

As the reeves drive pulleys get older they become worn and tend to wear away at the belt. If a belt shreds quickly this usually indicates excessive slop in the reeves pulleys, key stock, key way, spindle shaft and motor shaft that the pulleys ride on. On every revolution of a worn reeves pulley the inner face of the pulleys are flexing against the belt causing rapid wear on the belt. Most of the reeves pulleys are made of a cast alloy that has a limited life expectancy. Since the pulleys are moving back and forth along the spindle shaft and motor shaft when ever the speeds are changed you are creating wear on the inner face of the reeves pulleys which are made of a softer metal compared to the spindle and motor shafts. The reeves pulleys are usually the 1st component to require replacing on these types of lathes. A routine cleaning of these components will extend the usable life, excessive dirt/dust/grime on these components will quicken the wear.

Good to know.

I'm not surprised.

I do have to lube the drive spring regularly, and, even so I've begun to have a problem with the motor end sticking at slow speed, so I have the cover off not infrequently.

I'll take a look at the surface of the pulleys and see if I can clean them up better.
