    I am now in my second stint with Mack, having worked in Parts since 2005. I work at A420 Ballard Mack Truck Sales & Service in West Springfield, MA and previously worked in the same location for the last ownership, A466 Springfield Mack.

  1. There are dozens of possible spring weights and configurations. You will need to check with the dealer to see what is specifically in your truck.
  2. Ceramic lifters were phased into production in January 2002 beginning with engine s/n 1Y2008. However, From 07/2002 through 09/2002, ~1100 engines (serial number range 2N, 2O and 2R) were manufactured with steel lifters as well.
  3. This is also why it is so critical to use a proper coalescing air dryer cartridge on US07 and newer engines. Too many people try to save a few dollars by using older style non-coalescing cartridges or not changing them on time (once per year). Failing to maintain it risks not only clogging up the tanks, but screwing up your entire AHI system. From MTPI 561-016: Note: Proper servicing of the air dryer with an oil coalescing media cartridge is critical to the Aftertreatment Hydrocarbon Doser (HC Doser) system. The HC Doser system uses compressed air to purge fuel from the HC Doser nozzle supply pipe and the HC Doser nozzle. This air is also used to continuously cool the HC Doser nozzle and to prevent soot from the exhaust entering the HC Doser nozzle. The removal of oil from the compressed air system is critical to support the function of the air control solenoid valve in the HC Doser dosing module. Oil in the air supply can collect in the valve and cause it to stick, inhibiting the function of the valve. Additionally, oil in the air can collect on the HC Doser nozzle and form deposits which can reduce HC Doser nozzle flow. Coalescing Air Dryer Cartridges should be serviced and replace every 12 months during normal preventive maintenance.
  4. Assuming you are talking about a hydraulic master cylinder/reservoir assembly. There are several options, would need to know the last 6 of the VIN and whether you have disc or drum brakes.
  5. Actuator, yes. Flywheel, no. The flywheel can be turned. If it's not out of spec, it can be cleaned up just fine. If you're paying $10k for a clutch job, you're getting robbed. A clutch and reman actuator are ~$2000 combined. Even with using new hardware for the clutch and flywheel (which you should be, not worth saving a couple dollars by reusing the hardware), that's still only ~$100 more in parts. Can't think of any reason why you are paying the equivalent of 58 hours labor just to have your clutch done...
  6. Bypassing it is not recommended. If it's blowing and you are not 479% certain that it is not a bad breaker, you risk sending the entire truck up in flames. The breaker you are looking for to replace yours looks to be part number 21301448. Mack has 261 of them at their PDCs. This should automatically reset as opposed to hitting the button. If you want one with a button, look at a Bussman CB185 series breaker. You can find the 150A breaker, with a reset button on it, at Grainger under item# 6CJA2, Bussman part number CB185-150.
  7. I just spoke to the original manufacturer of the cover, they told me it is an obsolete part and have no cross to either another number or any reference under the current Mack number.
  8. General questions about this model would be much better answered in the Antique and Classic Mack Trucks General Discussion forum, there are many MS owners that frequent there.
  9. There is not enough information given to answer this question. Assuming the truck has a manual transmission, the answer would be yes ASSUMING it does not have a self-adjusting clutch to begin with. If it has an AMT, the answer would be no.
  10. Things like this are why we always strongly recommend never reusing the bolts. Over the years have had a couple occasions where a customer wanted to save $5 by reusing EUP bolts only to have one come loose or shear. For a couple of years I kept a broken EUP one guy brought back; when the bolt broke, it rattled so hard that it broke into a dozen pieces. Whenever someone protested about getting the bolts, I'd slap that bag down on the counter.
  11. Avon, MA is a former McDevitt location, now owned by Ballard Mack. The Springfield, MA location when they left State St actually moved to West Springfield. In 2010 Springfield Mack became another Ballard location.
  12. Any dealer should be able to print this out for you. Go into the parts department with your exact model and vin, and tell them what you need. The arrangement number I came up with for one of my customers 1994 CH613 trucks was 17MS727P2, although yours might vary slightly. The internal name for this assembly is "ELEC EQUIP INT-BASIC" Good luck!
  13. Antifreeze sold for Class 8 use will normally have the additive already in it. Up at our dealership, we use Houghton Security red antifreeze that already has the nitrite SCA (supplement coolant additive) in it for all shop jobs. By far, this link gives the best information on not only what your coolant needs to have, but WHY.
  14. I had a customer last year looking for the same item for several trucks. Some we had in stock, but others we were told, after a three-week wait, was that they could do it only if the customer wanted to pay $$$$$$$$$$ for tooling setup to make that one part. IIRC, the customer ended up taking a picture of the data plate and had a sign shop make new ones for him. Have you checked with your local dealer to see if they are still available?
  15. Great link. For anyone wondering if the newer trucks can hold up to this kind of load, check page 25 of the newest Bulldog Magazine.
