front axle air switch

[bugei]

has anyone "rebuilt" their front axle air switch? i don't see any clue how to do it in the tm, and everyone i have asked if "they have one in stock" has said that they rarely sell them. so i am guessing that somehow mine is the first one to leak (which i doubt) or that there is someone who knows how to rebuild them.

mine seems to be leaking and causing my front axles to always want to engage.

thanx

I think they're so cheap that they invite replacement rather than repair. Bendix TW-1 Control Valve is what you'd ask an air brake shop for.

jones.
is that part number the whole switch? just screw it onto the plate and i am back in 8 wheel drive ? any big truck shop?

thanx

Go to www.bendixvrc.com/itemDisplay.asp?documentID=4832 The control valves are on pages 30 and 31. TW-1 is a version number which is then broken down into lever and body material and finish.
Another handy book to have is; www.bendixvrc.com/itemDisplay.asp?documentID=4631
I got my replacement valves from my local heavy duty brake and clutch shop.
Whenever possible, go as direct to the source as you can. Any truck stop/truck repair garage is gonna tack on their mark-up.

Thanks Jones... I've been looking at those in one of my supplier catalogs wondering if they would fit as a replacment... Gonna order in a few for the store!

Vise grips on the air hose will shut off your front drive in an emergency.

jones, which fit and material is correct? is this the "exact" nos part? i have seen some discussion of rebuild kits for the tw-1, if it is the exact part, maybe a few minutes of rebuilding would "git er done".

thanx for the answers, the tm is surprisingly non commital on this part of the circuit

The switch new is all of about 15$ at most... Why rebuild a 15$ part?

 

[bugei]

devilman, i googled it really quick, and it seemed like it was about $30 to $50. i did not dig really hard, but sure did not see $15. but, you are the parts guy, so i trust your answer, actually, it is probably not worth rebuilding a $30.00 part.

Gimme a week or two... Email me to jog my brain and you will have a 15$ switch.

Just looked at the Quick Reference Catalog and I guess the lever on the TW-3 is closer in appearance to the Deuce's OEM switch. Your choice is steel lever Bendix p/n 283040X. The other two TW-3s are controls for vacuum applications.
As far as this being the exact replacement? Can't say for sure but since most of the controls... and axles and transmissions and gauges and wheels and tires and steering boxes (the list goes on)
are bought from various outside vendors-- it's likely that Bendix made the Deuce air switch.
