1 1/2" tall
.920" diameter
.213" thick
champher is approx. .283" deep
durometer reading of 60
These are the best I can measure.

thats the best you can do? to within 1/1000th. come on....

they are rare earth magnets about the size of a quarter. i have the part numbers of them i got from grainger somewhere.
there is a hall effect transducer mounted inside the coach on the place where the locking pins is. it detects when the slide is all the way in by the magnet going directly under it.
the magnets are superglued onto the top of the slide right next to the slide hole.
be careful playing with the magnet because as soon as the hwh controller detects the magnet, those slide pins will come down with hydraulic force. dont ask me how i know
they will punch through the top of the slide like a knife into hot butter

Think about this, all the bushing does is to keep the pin from rattling?
So then any rubber bushing that fits should work?
Maybe look for a rubber hose with same durometer and chamfer the top edge. Think that will work?

Forest. Have you seen one of the bushings. I agree there might be a substitute but I dont think a rubber hose will do it

I tried different hoses and weather seems to lift them out of the hole for awhile and then they swell a bit and seat, but then try and get thick, tight, dry rubber hose out of those holes after a couple of years. Not fun... The neoprene lightness and ply makes it dissolve in time instead of becoming one with the sleeve and that may be the reason it's used

How long do the bushing usually last on the average? I'm in the need of them, but don't want to wait forever from HWH. Wander why it takes so long for them to ship?
RE: slide bushings - folivier - 02-14-2014
No I haven't seen one, I was thinking they were rubber. They're a neoprene? Like an open cell foam?
RE: slide bushings - lbrachfe - 02-14-2014
Not sure Forest, but it looks and feels like that to me. They may be a polymer/rubber and or ? mix. They were specifically picked for this job as regular hose of all types does not work the same and if snug or loose a lot of rain water accumulation makes them lift in place

Chappell,
While I don't have a direct answer, maybe I can give you a little idea of how long they will last. When I bought my coach it had 40,000 miles. All four of the bushings were smashed into a rubbery pulp in the bottom of the lock pin sockets. So it appears to me that on my coach I may have to replace them about every 40,000 miles.
I replaced mine in July 2012 and have traveled about 25,000 miles since and they are still working.
As to your question on HWH. In 2000/2001 HWH had a bad batch of hydraulic line that began bursting and spewing atf into coaches. Many rv manufacturers, including Newell, looked for an alternative to a hydraulic system. Electric slide systems were developed by several different companies and HWH lost a lot of market share. Then came the rv downturn around 2009. HWH has downsized and is a much smaller company today. Best I can tell all orders must be produced and are not shipped from a shelf. This can cause some very long delays.
