The design of this machine is such that it is not only difficult to regularly install the abrasive but VERY hard to replace this part, which should never be able to fail so easily. The location of the hold down clamp is almost impossible to reach and remove without dismantling the machine but I did it. The nut, which secures the clamp,

Ordering and receiving the replacement part was a breeze.
I had to remove the drum which was pretty easy. Just unscrew some screws to take off the back cover then remove the screws that hold the left side cover and pull the assembly out. My fingers are to big to get at the small nut holding the fastener so had to go this way. The rest was easy just used a small box wrench & small Philips screwdr

I broke the inboard fastener on my Jet drum sander so I had to replace it. Getting a replacement from Ereplacement parts was simple and cheap.
Had to remove the broke fastener, which was easy enough. But putting in the new one was a little tricky because the screw is maybe 5mm. And your mounting it somewhat blindly because the part goes inside the drum. But you just have to be patient and make sure the screw goes in straight so you don\'t strip the threads.

Remove inboard abrasive fastener. Lock nut was stripped so I replaced all three parts.
The most difficult part of repair was collapsing the spring while attaching with lock nut and screw. I used a 90 degree pliers to hold lock nut while collapsing the spring. Overall repair went well.

It is difficult to figure out how to put this thing in the inboard (near the motor) end of the drum. I was successful in just a few minutes at putting it in the outboard end of the drum and pushing it with a 1/2\" x 1/2\" board to the other end of the drum. Remarkably, the hole for the screw lined right up and I held the lock nut on the e

One caveat is that there appear to be some balancing weights on the inside of the drum and these were in the way for sliding the fastener. I was able to use a screwdriver to fiddle with the fastener so it was raised above these balancing weights, pushed it past the weights and was done in about 5 minutes with the whole process. Too bad Jet didn\'t bother to provide some instruction somewhere in the manual about how to do this.
