Engine door nylon rollers

Decided a while back to replace the 2 lower guide rollers that locate the side plates on door. The old ones were quite worn and I had rotated them a few times to catch the arms and there was still a bit of play on them and door rattles some.
My Brother had a couple made in their machine shop so I did not need to shop around.
If someone wants to make some they are 1  3/4" dia x 1  7/8" long with a 1/2" hole

On our coach the generator door uses the same rollers as the engine hatch.  You can swap them out for a short term fix.  Generator door is much lighter and gets used less often.  Replacements at FOT were expensive.  Hard rubber sort of things.

For a really short term fix, you can rotate them a little bit and wrap them with electrical tape.... It's a cheap fix too.

I did a few rotations like I mentioned.
I decided to leave the gen door ones alone as wanted them all good. The material I priced at $20 cndn for a meter but only 2"in stock here so would have had to get them turned down but Geoff had stock at work and had them mailed to me.
A meter would have made about 18 pces, so cost each around a buck US before making

John, is that nylon or Teflon material?

Just curious if y'all think acrylic would work. I have a source I could get some round stock and turn it down to size. It's the stuff they make duck calls and other game calls out of.

Rick. UHMW it is a type of vinyl /nylon /Acetal but good for rollers etc as it stands up to wear better.

Could it be a urethane material?

Now I have an excuse to clean the dust off the lathe. Haven't had any use for it since retiring.

Ordered at 4pm yesterday from McMaster-Carr. Arrived at 10am today. Can't complain about that. This was nowhere near the top of my list of things to do but looks like a quick little project.

Those pieces look good. Use the chop saw at 1 7/8" long then drill a 1/2" hole on centre. The outside dia may be a bit oversize so check that it will fit into the bracket on back of door as you may have to reduce it a bit. Those stock plastics are usually a touch oversize.

If you don't have a lathe, or a brother with a lathe, there are online sellers who will make custom Delrin "bushings" to order.  For instance:

CUSTOM DELRIN/ACETAL Plastic bushings, made to YOUR SIZE, QUANTITY, and...
Or pm me and have the stock sent to me I'll cut and drill and ship them back to you. Just pay for shipping back.

Dsd, that is a nice neighbourly thing to do. I also would do it but the mail from and too Canada is so slow right now that a person would be waiting for  months to get them
I cannot cross the border till it opens so cannot access my mail box in Washington State for faster service.

Thanks for the offer Scott. I'll chuck them up on my wood lathe to drill and touch up any diameter adjustment. It should be sufficient for the precision necessary on these pieces. Hopefully I'll get time this evening to try it out.

My shop and additional equipment I have in storage is primarily for woodworking. I've always had some interest in having metal working capabilities but I'm limited to basic chop/bandsaw/drill/Mig welding.
