    Not at my fingertips, no. Mack engineering explained this to me years ago.

    I can’t help but laugh.  Your telling me I’m wrong and your reasoning is because ‘a guy told you so years ago.’  It fits very well with the last post about “not believing everything you read.” 

    I’m just trying to get the correct information out there.  There are people here that are looking for an answer (me included) and I’d hate to see bad information be spread.

    Produced by Wagner for Mack, they have significantly more force, a requirement for a 20k axle versus a 12k axle.

    That Volvo wants to charge you $744.85 for a $200 component should be a crime.

    Volvo doesn't want you operating a 1996 vintage truck. And they want to rinse their hands of "American" Macks.

    Do you have any information on this?  I disagree with parts of this statement. A type 30 roto-chamber has the same force as a standard type 30 brake chamber.  Area of diaphragm in sq/in times pressure.  I was under the impression the main reason behind roto chambers is packaging.  Roto chambers use an elongated diaphragm which “rolls” on its self while traveling the length of its stroke. This allows a smaller overall diameter while still having a large surface are of the diaphragm. 

    Now back to your statement, they may have more force for use on heavier axles but not do to it being a stronger chamber.  It’s due to the fact that you can fit a type 36 or 50 chamber on the steer.  

    To sum it up a t30 roto has the same force as a t30 standard. A t36 roto has the same force as a t36 standard.  It’s physical size that is the difference. 

  3. All the switches are lit up internally. The hole in the top right is for my cell phone mount that’s not shown.  The wiring is identical if you use the correct switch bodies but it is necessary to change the connectors to match.  Here is the finished product after lettering.  Hopefully I’ll get it mounted this weekend.

  4. Thanks for the kind words.  To answer a few questions; no speed control because this panel is going in one of the E9 powered CL’s.  I realize I used the wrong trucks panel as my example.  The reason there are 3 “pto” switches is because I run a neutral lockout as well as a dual pressure pto.   Unfortunately I was not able to get a factory labeled switch for those purposes so there will be decals.  I should have the finished product tomorrow so it will make more sense.

    If your valves are working right, there should never be an air passageway from the exhaust manifold to the atmosphere (other than out the stack). There may be a intake or exhaust valve open, but never at the same time.




    In some engines this is true but more often than not there is valve overlap. Meaning both intake and exhaust valves open.   This is common for cooling the exhaust valves. Also heavily used in emissions engines. 

    Ive never had luck with that cement. It looks good when it dries and you have such high hopes, but then after 2 miles it’s right back to square one.

  6. Looking to sell one of my projects. I bought this with intentions of making it a flatbed truck but there is just not enough time in the day anymore.  Truck has 85,000 original miles on a e7 engine. Motor is in beautiful shape. Mack 5 speed, 44k camelback (needs bushings),  drives and shifts nice. Was a recycling truck in a small town. Cab is rusted in rear corners.  Would like to sell whole But willing to part out if necessary.  I’m looking for $4200, that’s what I have in it at this point.

    I got the part numbers for the 2019 pinnacles but that’s all I ever got, although I love the new pinnacle headlights, I just couldn’t justify spending the $1200 my mack dealer wanted for the set.    Maybe later down the road I’ll impulse buy a pair and share some pictures with you guys, but all in all, I only have about $120 and a little bit of my time into these headlights I made.  

    If you don't mind what part number did you come up with for the headlamp assembly on the new pinnacle?   My dealer doesn't have a full assembly part number, only individual pieces. I'm curious if they will fit in the CH/CL hood.

  8. I have experience with these Roush propane engines and let me tell you, they are junk. I do a lot of work for propane distributors and they buy them for tax credits.  One of the 2017 F550’s just got a replacement engine at 40k miles. They get about 4 miles to a gallon which equates to 150 mile range.  All the guys carry a spare 100lb tank just in case.  It has 2 speeds, idle and floored.  Another truck had a liquid line that feeds Roush’s rail blow off going down the highway. Driver couldn’t see and the whole area was blasted with propane. Lucky there was no fire.  

    About the only good thing is cheap fuel. 

  9. I live right down the road from where this happened.  This was a stupid decision on the part of the bus driver.  The emergency turn in the median is very large and I've seen many a cars do a uturn. I would never have expected a school bus to try that though.  The company  who operates the dump truck are notorious for being over weight and driving like maniacs. They cut in and out of traffic like race cars. So it was poor judgment on both ends here and a lot of kids are suffering for it. 

    This accident really breaks my heart.
