Delta belt sander parts

I recently acquired a benchtop disc/belt sander from my father in law. It hadn't likely been used at all in 2-3 years, and while running it last weekend, I heard a noise that sounded as if the bearings on the idler drum on the belt portion was going bad. Took it apart this weekend, and found it is actually a bushing, what was left of the grease was scorched to the bushing and shaft. Cleaned that off with some thinner, shaft looks alright, but there is some small scored on the bushing...now for the fun part...

Delta apparently has been sold so many times over the years, that replacement parts are pretty much non existent any more. Indefinite back order is the word I am getting thus far. I was thinking of replacing the bushings and the rubber washers that basically dampen vibrations (they were half torn, and I finished tearing them removing the shaft from the drum). Now I am contemplating taking some 400 or 600 grit sandpaper and trying to clean up the bushings a little and putting it back together, and I might try and salvage the rubber washers with some rubber cement. What kind of grease should be in there? Any thoughts on how long this band aid might last or should I go on a hard target search for bushings, measuring what I have and going through industrial supply places and just match them for size.

Thoughts?

I'd be less worried about the bushings than the harmonic dampeners, they sound trashed. Were it me I'd spend a bit of time with a micrometer and McMaster Carr's search function. Probably easier in the long run and cheap if they are just bronze bushings a rubber washers you are replacing.
 
Depending on the year you may find parts here.

Boy, when it was described as a rubber washer, I wasn't so worried, but when you call it a harmonic balancer, I'm kind of worried...

I've had good luck with McMaster Carr's search function for bushings. Give it a try. To bad you don't have a real machinist friend to help you out.

You could try a hardware like ace hardware. There is one in my area that has bronze bushing. You might have due a little modification to it if it is something close. Also, take some solvent and try to clean the bushing you have and see how bad the wear is and try to get the right I.D.. If you do a web search for bronze bushing you get several places to try.

Thanks for the offer. I know a non-retired machinist in the K-zoo area. I had a little breakthrough later this afternoon. I got on the phone with the local Dewalt service center (which officially still carries Delta, but in his words the days are numbered) and he found some parts that were just "released" from the warehouse late last week. He wasn't promising anything, but placed the order and is hopeful in 7-10 days I might have my parts. He was definately friendlier and more professional than the emails I had got from some on line parts suppliers.

Alternatively, talking to one of our mechanics at work, he knew of a couple local places that carries generic bushings that I could go in and size it up and thought they might have rubber dampeners too (so that is plan B)...Plan C will be to get something made...or I just resort to the tool being a disc sander (without a belt) but I was really looking forward to the belt portion of the tool, especially for making keels and smoothing the bottoms of deeks before installing keels.
