not something I would want to hit head on!! nice truck

I worked at UPS for 4 years back when I was in High school. I was told that the reasons none of the trucks or package cars had mfg names was that they did not want to show favortism or advertise another mfg name. I worked on a dock next to the maintence bays and back when the CH macks had handels in place of the dog some of the drivers would remove the handel and place the dog back on. Some drivers even bought and put the OEM lettering back on the truck disregarding company policys. If you look at some of the CH macks they likely have a dog or handel in its place but no "mack" lettering across the grill. The F and MH models at the time also had no dogs. Some of the new packagecars I think are freightliners chassies? I havent looked close but I did see a few stickers with the FL name on it. not shure who builds the bodies. Trent

nice pics matt~ noticed the nice looking valuliner in the background as well Trent

THIS ONE BARRY?

I used an R model lower box and plan to incorparate a B model cover to it. Trent

"I could bleed out the air already in them." IS THIS ON A B OR R MODEL? REMOVE THE HOSE FROM THE VALVE ON THE SEAT. IF AIR IS ESCAPING THE HOSE YOU HAVE AIR TO THE VALVE, THE VALVE MAY BE BAD. JUST FOLLOW THE LINE TO WHERE IT CONNECTS TO THE AIR SYSTEM. I HAVE NEVER HAD AN ISSUE SO CANT SAY WHERE THAT LINE GOES TO. SOME TRUCKS RUN THAT LINE BACK TO UNDER THE DASH WHERE THERE ARE AUX PORTS FOR ALL THE MISC AIR CONTROLS

Thanks for the kind words folks. I dont think im shy about my Hourly rates. I charge $75 an Hr for the dump truck and $85 for the lowboy. sometimes its per load if I can cut a good deal and get rid of it quickly. I "rent" both the trailers from my old boss and longtime friend.(he was the first to hire me when I was 21) sometimes I throw him some green other times I just move a machine or some truck loads of clay for him. It works out good for both of us. Im only plated for 73,280 so I cant haul large machines legaly. I work a 9-5 job so right now its just weekends,travel days that I get off from my M-F job and vacations. I know what you are saying about the job market. I see some guys charge cut throat rates, then pay for a driver/fuel and at the end of the day then dont have any cash left to put into the truck. its a shame I think im on par because if I get contracted out thru a friend I charge him $70 hr and he gets a $5hr cut for finding me the work. I dont mind do in that as it pays fine and it still keeps the marked steady for the next guy. what are the rates like up in WI? Thanks again Trent

well I finnaly bought commercial plates, insurance, and started a small company recently. Hope she will like to learn new tricks. here are a few pics of the dog at work.

Dave I think most of the active members here have followed your saga for the past 1-2 years. I feel your pain hope that engine is salvageable. keep us posted Lets see I was busy all this week replacing stuff I replaced a front drive shaft, and this new one has a real nice vibration. It needs to come out and balanced again replaced the old torq rods but one bolt is broken off and stuck in the trunion crosssmember(under 5th wheel) broke an antenna off from a low tree limb. the good news is I bought commercial plates recently and there paid for along with the parts that I have replaced. hope to stay in the black now for the rest of the season. knock on wood! Trent

Terry, I thought "GK" was for gliders???

RD600K? is it possibly a glider kit??? that would explain the small 237 engine in a new frame.

Nice pics packer! Bulldog : it looks like a small cab before the change over to the larger cab in 72-73. also the hood is not tall like the later RS was. I think the tall RS hoods came out during the change over in 72-73 as well Trent

are you welding the bungs to the end of the tank or on the sides? I had a welder friend of mine install both bungs on the sides for a cleaner look and to hide them. we welded a stiffner plate to the sides where the bung went thru to reduce the flex from road vibrations. let us know how it turns out

the tip turbine set up would seam almost as simple of a project as moving everything for an frontmount IC. The turbo may need to be clocked diffrently but other than that pretty much would be all bolt on. If it converted the engine to a true 285. Would the HP rating max out the cooling capasity of the small rad.??? Not shure when the rad support braces were changed but another thing I notice is that the air ride cabs(that I have seen) do not use the "X brace" that bolted to the cab. I had helped work on a mid 80s R that was built with a solid mount cab. We were converting it to an ride cab and removed the X brace. We bought the later style rad braces but they did not fit as the front shock absober mount was installed diffrently. we ended up making our own brackets.

that engine looks like an rebuilt early maxidyne... 237??? judgeing by the crossover pipe from the turbo to the intake (no intercooler or turbine charge cooler) The problem I see installing an intercooler on that truck is how the radiator is installed, most of the R models I have see with the IC had the radiator moved back a few inchecs to accept the thickness of the IC. This will effect the space allowed for the fan/belts etc... I think the IC cores are about 3 1/2 thick. if you have a spacer plate on the fan that can be removed to place the fan closer to the engine thats a good sign it may work?.however you will need to get diffrent pullys that are offset to accept a tighter fit? also if the truck has A/C or shutters that takes up even more fitment room. might have to sacrifice something? Trent

one thing I would recomend, as you are scratch buildng the system, is to add a 2 line wet kit. this would allow you to pull lowboys if you ever need to move one. something good to have and easy to install with all new parts.

I dont remember the min amount of hyd fluid I needed for short dumps but I think I was told 40-45 gal min? I added about 5-7 gals more because I used the large 126 gal pass side tank and was worried about it sucking dry if I was dumping on an incline. Most of the trucks here in the city use the pass side tank for hyd fluid regardless of the size. The tractors set up from the factory for a dump tractor would have a amall 50 gal pass wet tank and a 100-120 fuel gallon tank on the drivers side. my opinion is anyone trying to save weight would just use the pass side tank for hyd and have only 1 fuel tank. my 2nd B had a rectangel wet tank mounted behind the cab. it was pretty small but I guess it did the job with short trailers? never did use that tank but it was small! I have also seen many trucks have 2 fuel tanks of the same size and then the wet tank behind one of them, any choce is fine but I would rather use the frame rail space for something more usefull. on my RS I was able to put a 24" long tool box on the drivers side rail. Was a much better idea than a wet tank located there. Trent

Well, I added 40-45 gallons of hyd fluid in my 126 gal tank and it dumps and works just fine with low boys and short dump trailers. The amount of fluid capasity needed is dependant on the hyd piston. I havent pulled a long dump but would suspect it needs more fluid than a short dump because of its hight travel? are you running 2 fuel tanks right now? what size are they? if you have 2 large tanks you could convert the pass side to the wet tank. or if you want to be real trick. have a shop seaparate the pass side tank for fuel and hyd fluid. something I considered but dident want to spend the $$$ on. im not a fan of the top of frame mounted tanks that sit behind the cab. ugly in my opinion Trent

details please !!!!

Hello and welcome to the site Insurance....http://www.racensur.com/ ...pretty cheep if you use it for shop and show only plates.... go to to your DMV and ask for antique plates. if the truck is an anteque I dont think you need a CDL to drive. Diffrent states have diffrent laws. Check at the DMV. I will say It does help to have one if you get pulled into a scale house. you wont need fuel tax stickers,log books or that other commercial junk with antique plates. Again just check with local laws to be shure in your state. In IL You need a truck with air brakes to take the tractor/trailer CDL test. not shure if traile needs air brakes or not.

Could it be a timing issue after the rebuild?? did you mess with the timing or anything that would upset performance. I guess what im saying is check with the simple stuff that you can perform. fuel press,boost leaks, etc... if all checks out dig deeper into engine programs and computer stuff. the price for an engine hp "upgrade" is pretty steep here in the US as well. I know that you guys get higher HP upgrades than us over here . whats the cost for a engine code scan at your dealer dealer? that may be a cheep option

crank or rod bearing would be mu guess? did the knock change when you let up on the peadal? sorry for the bad news Trent

I know you could get a Cat in a superliner, and I belive the ultraliner and superliners shared the same frame???? someone will know for shure for me, I would drive a old mack engine before a new cat was under the "dogs house"

I see your point Brad, and its a good one. I think many people are afraid that Volvo will do to mack, what they did with White trucks. I agree that mack is better off built under volvos name than to not be built at all. Volvo is a strong company,so thats good thing. I just hope they dont suprise us with "bad news" I hope the MP8 is as good as some have said. I have heard it compaired to the old maxidynes "can feel the power band" the elec versions of the E7s shure were not known for grunt. I also think it will be a very good move if they put the big HP (600hp?) engine in the mack for the heavy haulers and low boy trucks. 405hp is not huge power that most owner operators look for. dont get me wrong 405hp is plenty for me but there is a market for big hp engines, and mack is completly out of that market currently. cross my fingers

Scott the cans were pretty cheep $5-$7 dollars if I remember correctly. i think 2 cans did the dash and interior cab steel. I have not found the meterial used for the panel faces. I ended up getting some panels out of a parts truck that was in fair condition. It does seam odd that you cant get interior parts for the truck when it was discontinued a few years back. I tried looking up parts for a few year old R,RB,DM, etc... had no luck will all those vin numbers? I even tried for the R model ledgend and had no luck. Trent
