Re: Compressor cycle ? Reply #27 – January 08, 2017, 12:57:30 pm I suspect the brake can's are leaking and Foretravel had given me part # for cans L- C28-3276X24 R- C29-3276X24 looking at old cans they say Type 24 Brand MGM and they have a tag 2.5 in or 54mm stroke , they look like Short shafts. Found can's were about $250 to $275 apiece. Quote Selected

Excerpt from Bendix manual linked in my post (above):A. Remove the top cover from the governor.B. Loosen the adjusting screw locknut.C. To raise the pressure settings, turn the adjusting screw counter-clockwise. To lower the pressure settings, turn the adjusting screw clockwise.Note: Be careful not to overadjust. Each 1/4 turn of the adjusting screw raises or lowers the pressure setting approximately 4psi.D. When proper adjustment is obtained, tighten the adjusting screw locknut and replace the cover.Note: The pressure range between cut-in and cut-out is not adjustable.Argggg! Given a 50/50 chance on getting something right I will be 100% wrong! see yaken Quote Selected 1 Likes

No you can't do it your self as you need a special press to keep from getting killed taking them apart, some of the new chambers are now sealed to keep people from getting hurt. The diaphragms are about $10 each , springs $7.50, cleaning and rattle can paint and your bill should be less than $120 for both (possible slightly more due to parts needed and the area you live)Pamela & Mike Quote Selected

Re: Compressor cycle ? Reply #32 – January 08, 2017, 03:10:48 pm The brake chambers (cans) come two ways. Complete chamber has the piggy back and diaphragm and mount with the pushrod sticking out. This needs to have the pushrods cut to the same length as the one you remove and you may have to spin the piggyback in relation to the two mounting studs to get the airlines to reach ok with some slack. Piggybacks are just the section with the park brake spring in it up to where the diaphragm is located. The ones I buy have a diaphragm and clamp included. Apply service brakes with air and while applied clamp the pushrod with vicegrips (holding the brake applied) then cage the park brake, insert cage bolt and push on brake button to make it easier to run the nut down so the spring gets trapped. Then undo the lines and the diaphragm clamp. Type 24 is the size of the chamber 24 square inches and the stroke indicates long or short stroke. I recommend having some experienced help with this for the first time you do it. Quote Selected
