  2. I was at the museum a little over a year ago. They had alot of files there for that vintage. It was a bit of a bummer to find out they were lacking in the files for trucks built at the former Oakville, Canada plant.(VIN #'s starting with 2M2N) Mack Canada and Toronto Branch disposed of alot of files and drawings rather then sending it all down to the museum when they downsized Canadian operations. I Know a guy from the inside that was really upset with that. He did all he could to covince managment to ship it all back to Allentown. Huge let down for Canadian die hard Mack fans. Good luck though.
  3. Our 1985 Mack R688st sitting outside of our shop.
  4. I have noticed the same with our 2005 CXN and 2006 CHN. both are EGR and as noted in all our engine spec sheets the sweet spot is 100 rpm higher or more in comparison to non EGR e-tech engines. One truck has an 18 the other a 13 fuller trans.. runnning in the second last gear(split) at 62mph both trucks have seen a slight fuel milage improvment when hauling full loads. (rear ends are 370's)(22.5 tires)(overdrive trans) Both trucks have over 500 miles and smoke alot less on each shift when shifted just above 1600rpm. Turbo vane/egr valve burp issues we had when shifting have dissappeared since changing shifting patterns. both turbo's are original. The 2005 is a 355/380 the 2006 is a 460xt. The 460xt is a dog.
  5. I spoke to the Mack Canada marketing rep. back when the Titan was being rolled out. He told me Mack at the time, were looking at adding a 36 inch sleeper factory sleeper to the Titans list of options. ( The sleeper would be similar to the Kenworth sleeper option.) He also said at the time there were no plans of offering larger sleepers like mid-rise sizes etc. only flat tops. That was a while ago. I was at the Mack test center about a year ago. They were making it sound like because of the economy and low demand on the TD model they were holding off on the development. (Huge Bummer) From what I can gather so far, you can order a Mack sleeper seperate from your dealer (fully dressed). If you have an awsome body shop like we have at a Mack dealer not to far away from us it can be mounted and look like factory. (A little cut and paste) Of coarse at a cost.$$$ At the dealer I speak of, they add and remove mack sleepers fairly regularly. They removed one for me. The Titan cab is pretty much the same set up as the other cabs from Mack that can have a factory sleeper added. That Titan looks awful with that sleeper. To make it simple all Mack would have to do is bring over the sleepers from Australia. Some of them look better then ours.
  6. Keep an eye on the coolant color/texture. At an almost all mack fleet I worked at we had lots of (plate type) oil cooler failures. probably over 1/4 of our 1999/2000 model year trucks (over 100 macks in the fleet) had the coolers replaced and an updated coolant bybass hose installed. We also had 4 engine blocks that the casting dust was not cleaned out properly causing the dust to settle in the air compressor coolant passage, causing cooling system problems to the compressor.( would melt the plastic air line for unloader signal at the compressor) It will look like dirt in the coolant and our trucks didn't have the cooling system filters to strain it out in time. If the color/ texture of the coolant doesn't change I would suspect liner/head area problems aswell. How is the engine temp on a hard pull etc? is the cooling system building up pressure faster then normal, before the engine temp. comes up?
  7. If you have the breather on the front right side its and E-tech engine. If the breather tube comes from the valve cover its a good old E-7. The E-7 was in the start of '97 and E- tech near the end of '97. Depending on which motor you have, you can have different problems. Which motor is it? Have you tried putting a new plug in the filler tube? ( don't take that the wrong way) It's happened to me, and while driving it blew some oil out. Is the oil level normal? (E-tech problem)
  8. I hope I wasn't misunderstood. The old man was saying the HFB70 box is NOT the right box for that series of R model. The SGP49 is what it should call for made by ross. Mack part # 20QC4257P2 Hope that helps.
  9. My old man worked at Mack in the parts dept. for 30 years. He says the HFB70 box is a late 80's heavier box. You should require a SGP49. part # 20QC4257P2
