kscarbel2 4641 Posted May 18, 2017 A Williams air valve? No longer available? Quote Share this post Link to post Share on other sites
BAD DOG 468 Posted May 19, 2017 Last one I had was on my MH which used the same one as a CL and if I recall I m pretty sure I had to buy the whole slave cylinder for the pedal because they didn't sell a kit anymore that was about 12 years ago . I think I still have a couple used ones not much to them inside just a couple o rings should be able to find o rings somewhere that will match up. Mack has just gotten terrible with anything V8 related . Went to my dealer yesterday to price a crankshaft gear cam gear and seals gaskets and a damper for one of mine they wher just out to lunch . What they were able to fix bs on the computer was priced just totally retarded. Already found a couple other sources so I guess I won't be buying from my Mack dealer .

AZB755V8 596 Posted May 19, 2017 Williams and Bosch make air throttle control valves still. If there are no parts from Mack there maybe directly from Williams? If not there has to be another currant control that can be retrofitted. The air cylinders are available from many sources, not a Mack part, but maybe even a direct fit. Google: micro air cylinders. The other option is to convert the throttle to the old cable type that was used on the older V8's with puff limiter. Quote Share this post Link to post Share on other sites

There intent is to make the old mack stuff unreachable buy pricing it out to lunch make it go away ! The dealer is only part to blame their pricing to the dealer is ridiculous as well the dealer is just passing the gouge on! Look else where! Best aftermarket mack parts is PAI in my opinion! excellent pricing compared to the volvo criminals Even for MP and volvo trash parts. AND better warranty! 1 1 Quote Share this post Link to post Share on other sites
