  1. All, Thank you for the response, it has roto chambers on it now. I'll have to look into the space issue, to see what will actually fit. I remember 20 years ago, there was a place in New Jersey that came up with retrofit kits to convert just about all of the stock applications, from the old wedge brakes all the way through, over to spring brake canisters. It's been soo many years that I lost track of them. I found out about them because I was doing a complete brake job on an R model tandem tractor and it made sense to go the extra expense to change out the spiders, and whatever else necessary, to accept the kit to convert to spring brakes.
  2. Is there a conversion set up on the market to retrofit spring brake chambers to the rear drive axles of my 55 Mack LJSWX, or do I have to fabricate my own set up?
  3. Mack Pro, Thank you for responding, I'm sorry for the delayed response to you. I haven't been on since I last answered you, and I didn't know that you sent more correspondence. Please realize that I really do appreciate you taking the time to answer and help out with my problem. Here's what happened. I said that the truck has been doing this from new, it's been back to Mack at least 8 times for the problem, they kept telling me clogged filters, (bull$&%t). I started to think that it had something to do with the def system, so I asked the driver if the truck goes into regeneration often, he told me the truck only went into regen once since new. I thought that was strange. Last week he got back to the garag, at the end of the day, and while backing into the yard the truck started to regen, It went for 50 minutes, since that time the truck is running perfectly.
  4. Joey Mack, Thank you, I appreciate your response!!!!
  5. After I did the delete, Mack programed it. After putting more time into this, I'm starting to believe that it's something in the DEF department. Still working on it as It isn't a constant problem, it's more intermittent. Thank you all that have responded, it's appreciated. I'm an old dog in a new world, and I'm still feeling my way around all of this computer and electronics garbage.
  6. Mackpro, Thank you for the response, I've been busy and I never had a chance to get on the site to see if I had any replies. I remember doing the delete probably about a year ago, Mack sent me the part and we did it in house. I will have to check the flapper in the filter housing, as I don't think I've ever seen it. We drop the filter, clean the housing and install the new one. I will check that out. Thank You for your time and attention I appreciate it.
  7. Is there a fuel pressure sensor on a 2020 Granite GR64F with 425 MP7, that senses low fuel pressure and causes the truck to loose all power. This problem has been present since new. The check engine light comes on and the truck looses all power. Mack changes the fuel filter, resets the computer and says fuel filter was clogged. The truck runs well for three weeks with new filter then starts all over gain. We clear the computer and reset and the truck runs well, for anywhere from one day to three weeks, repeatedly after reset, without changing the fuel filters. We run beautiful clean fuel, I know the filters are not restricted, ten other trucks and ten other machines, running off of the same fuel, never have a problem, or have a fuel filter changed, for any other reason except a regularly scheduled service interval. Could there be a defective sensor that senses a very light normal restriction and it sets off some kind of fuel shut down?
  8. Is it used as a fuel relay?
  9. Can anyone tell me where Relay # 2MR2149M is used on a 2001 RD Mack with a 460 Engine
  10. What a beautiful looking truck. Fantastic Job well done!
  11. I was following the progress on a beautiful B75 mack tractor. The chassis was stretched and so was the nose and hood. I believe it had a 450 big cam cummins installed in it. I had the thread saved so I could go right to it to check the progress. Somehow I lost it and I can't seem to find it anywhere. The truck was a light purple and the guy was doing such a nice job with it. Does anyone know how I can find that project again. I believe it might have been a 57 B75.
  12. My 98 RD was doing exactly the same thing. I suspected it might be a liner. When I tore it apart it ended up being 2 of the liner seals were hard and crusty like bak o lite.
  13. We have always cut them out with the torch. Take your time , don't go crazy, light blast pressure and you'll be fine. Just wear your protection, the sparks and hot metal only have one way to go and that's right back at you.
  14. By any chance, did anyone ever check the harmonic balance wheel
  15. Thank you for that information, I'll check it out.
