Posted: Mon Apr 01, 2013 9:16 pm Post subject: Guide Bushing for E-Brake shaft |
|
|
Has anyone found a source for new guide bushings for a 1968-79 Bay Window Bus. Mine is missing and the extra "slop" between the support bracket and the shaft allows the brake to be released very easily and sometimes in a very in oportune time! The bushing will keep the shaft tighter in it's travel in other words. I've thought about using a grommet but they aren't really stiff enough and would eventually pop out of the bracket anyway. I've found used ones at the salvage yard but if you try to remove them, they are so old and brittle that they will break...Them back to step one! |

Not really sure which part you mean, do you have early bay with inside cable adjustment or later bay with adjustment underneath. Do you have a picture?
Do you mean the hinge pin bushing for the e-brake handle? You might just have to get one made at a machine shop. |

|
|
The bushing on the E-Brake shaft support bracket (under the dash) that the shaft slides back and forth through when you set/release the E-Brake/parking brake. It keeps the shaft centered and steady. It was originally made from plastic thus after years in a bus it becomes brittle and relatively impossible to remove intact. About the size of a quarter. If I had a lathe, I could turn something that would last forever but...I don't have a lathe. Maybe a drill press and a file...With a load of patience! In other words, used ones are almost useless as they are work-hardened and will break when installation is attempted. |

The piece you're looking for is called the guide sleeve. The one that sits in the trim plate on the end of the ratchet bar bracket. Anyone out there know where to get one? I know I could use one. Can anyone make some? |

I'm looking for this myself right now. I've located them in Europe but the shipping is a killer. Anyone come up with an alternate or know of one that's available?

Well I was contemplating spinning one up on the lather out of Delrin, but it's so much easier to just buy one. _________________ Rust NEVER sleeps and stock never goes out of style.

There is someone in the Vanagon world that makes a delrin bushing for the sliding door handle. I bought one and installed it on my '87 Vanagon. Excellent part, well made, perfect fit, but, at this time, I cannot find the manufacturer. If we could find him he might be interested in turning out a few parking brake handle guide bushings.

Me too and probably many others.
I went to the Cool Air site in the UK and am inquiring about the shipping price for ten.

Uh.....why fabricate.....thats a split panel bushing. You can buy them, from mcmaster carr and possibly fastenal. Unless the size is grossly special, you whoul be able to find a part largely identical in a wide range of places.
Delrin, probably....although delrin is a bit brittle for a flexy part like that one.
The proper anti-wear material would be UHMW or mds filled nylon. Someone post the basic dimensions. Ray |

Okay Ray,
I just measured using a digital vernier caliper and what I got was:
Shaft OD: .552"
Hole in panel: .795"
I've purchased from McMaster-Carr before and found them to be great. As I remember the package arrived the next day. I'll go take a look on their site. I hope you're right. _________________ Lead Mechanic: San Diego Air and Space Museum

Yeah...McMaster Carr is just plain awesome. I have literally built entire production lines straight from the catalog. Its all in stock. I have been to their Atlanta branch to pick up from will-call. About a million square feet stacked 35 feet high...all computer/conveyorized....awesome!
The size you are looking for is metric 14 ID x 20 OD.....or 9/16" X 13/16 (actual is 25.5/32")....can probably get away with a 19mm outer diameter.
You need to know thickness also and the thickness of the panel//part is snaps into so you can get the barbed section the right distance from the flange.
These might work http://www.mcmaster.com/#panel-grommets/=toego8
Part #5269T43 is slightly oversized on the OD (27/32") and is made of black or white nylon...your choice. $7.10 for a bag of 100
Also http://www.waytekwire.com/products/1397/Bushings-Plugs/ some interesting choices
and http://www.steinair.com/store.cfm?tlcatid=14
And of course these guys have the baddest ass selection of plastic strain relief and hole bushings http://www.heyco.com/Strain_Relief_Bushings/produc...f_Bushings
Here is another brand with a sizing tool http://www.cableorganizer.com/richco/open-snap-in-...Mgod2EoAfw
and http://www.cabletiesandmore.com/open-snap-in-bushings.php
and http://www.pacergroup.net/Categories.aspx?Id=Snap_Bushing
I have actually bought split panel bushings identical in design to what is required. There are a zillion manufacturers. Just have to shop.
Keywords: panel bushing, split panel bushing, snap in panel bushing, split snap in panel bushing, snap bushing, split flanged bushing, snap in flanged bushing
But what you are looking for is a self locking, snap-in, flanged panel knock-out bushing.
I am still searching but I have seen over 200 designs just in the past 20 minutes. There should be no reason whatsoever to fabricate a part like this. Among the thousands of designs and sizes available for like....pennies each...its just a time factor for searching. Ray |

This subject just sorta dropped but I still need a bushing. Ray, can you please point directly to the part that you think will work? Anyone else have an idea? Getting some from Europe is still an option if we can do a group buy. _________________ Lead Mechanic: San Diego Air and Space Museum
