53 A54

Recommended Posts

I recently bought a 53 Mack A54.  The treadle valve will need replaced.   This truck has front brakes so I was wondering if anyone here knows where and what valve I will need to replace the original with?  I would like to keep it original as possible.

I think my A-40 has an E-3 series valve in it but I'll try to remember to verify. I had found a kit to go through mine, (20 or so years ago) but never needed to and it seems like that was the nearest valve in appearance.

Thanks.   I have attached photos of the valve here removed. Its a Bendix Westinghouse and has a number on it of 230870.

That valve look familiar but I've never had mine out of the truck. I'll be out to the shop in a bit and have a look see.

I bought a new replacement for my B on ebay awhile back and I don't think it was that expensive.  I think it was an E3

That seams to be the one that will work. I will just have to reshape the lines going in. 

Does  your B have the maxi-brakes?  I am hoping to replace the gasket in my old non-maxi style brake chambers and get them back in working order. Just wondering if anyone has had any luck doing that.  

I have a lot of fixing or manufacturing to do on this A since I am finding so many parts are obsolete. 

 

Thanks

Yes my B has maxi's.  it has axles from a modern freightliner under it.    From whit I remember the treadle valve is it only had 2 compartments internally.   The top half was wide open and all ports where supply and the bottom half where all going to the brakes.    I could have the upper and lower mixed up, but they where both just open cavities with different ports all around the body.
