There was an aftermarket fiberglass hood for the B61 and LT models. This topic came up a wile back and I do belive it was said that Mack did tinker with there own fiberglass hoods near the end of b model production. it makes sence as I have seen 2 diffrent virsions for the B61 models.

Nice truck ...keep her running! If no one can help here ....there was an aftermarket company that still offered some parts for the old quads. the company is PAI out of swuanee Ga. Search google for the phone number. they had a few stores here in chicago that sold aftermarket parts but they have recently closed there retail outlets. they may have retail stores elseware?

for the amount of wire in these cabs its not a huge deal to re wire them up. think about it. new guages would have back lit lights on each one or use the old guage where one bulb lights up 2 guages. you have an amp or alt guage/ fuel/water temp/lights/marker lights/ turn signals/ start switch and a few others. to start get a painless wiring fuse panel http://performance.alternatefuelsracing.com/painless.html (12-CIRCUIT UNIVERSAL FUSE BLOCK # 30001) and run the wire your self. I feared if I bought an aftermarket harness that The lenghts would be incorrect and if I had to add soemthing to the truck later there were going to be stray wires anyway. just my .02 trent

first slam your hand in the screen door of your house on the way out to the truck. this puts you inthe correct mood! They can be a Real PITA to get louse. My B had the wheel so rusted on that even an engine hoist could not get it louse, i ended up damaging it and just ended up cutting through it and got a diffrent one. As rob said lousen the nut but leave it on the end of the shaft so that it dont go flying around as it comes louse. put some PB blaster on the splines, put the washer or a bolt down in the shaft to avoid mushrooming the shaft end. try hitting it with a BFH as someone pulls up on it. I have also some times used a bottle jack to aid in braking it louse. Put a 4x4 on the floor, jack on top of the 4x4 and then a 2x4 cut to the correct length to help put bressuer on it as you smack the washer/bolt on the shaft end. some are easy some will make you pull your hair out!!!

Its a great looking mack and I Would think again about selling it. but to each his own. looks like It has many of the factory bells and wistles that everyone wants. and heavy haul. that adds to the price grately. It just depends how bad someone wants it. list it high and if it sells you got a good sale price. If not its still yours to sell later. I would think 50K is about what most people would pay. so try for the big spenders and list it for 60K+ Just a fyi these old rare trucks seam to becoming collector pices. It may be nice some day down the road to just say you have one ....just for bragging rights!!!!

HA HA! thats funny!!! a little 237 pulling like a big v8.. just tell who ever asks that its a 673!!! or just put some v8 emplems on the hood and dont talk about it. Ya we were bummed out a bit about the canceled pull but it would have been a mudslide if they kept going. I told PJ that I was not going to pull with the RS as it would have been a wet repete just like lake County was. If you hear of a pull let us know Trent

thanks for the tips. after more thinking last week I decided to buy it today The trailer is 22' long with a 4 stage hoist. the guy who owned it used it for concrete and said he never had an issue with it gtting stuck. at one time he had side boards and said it would haul a normal load with no problems. That was my only concern as I dont want to get a load of stone and only put 2/3 a load on. The tires are real good but the brakes are real bad so I had to back them way off to get it home. The tail lights need some work as its a rats nest of wires back there. Hopefully in the next month I can get it up to good working order and go haul some dirt. The trailer was located near the White Sox ball park in south Chicago have no clue about the postal trailers? Trent

sorry man... this program I use at work needs the caps lock on all the time. half way thru my typing I notice its still in caps so I just continue just the plane old standard adj slacks. I never liked the automatic type on rock trucks Trent

5.5MPG is avg 6MPG if your good (slow and steady driver)

THIS JOB WAS DOEN WITHOUT DRUMS AND WITH AFTERMARKET PAI COMPONETS, SLACKS WERE $20 A PICE IF I REMEMBER CORRECTLY? BUDD RIMS AS WELL AGAIN THIS WAS OVER A YEAR AGO AND DONT HAVE THE EXACT COST IN FRONT OF ME TRENT

I have never pulled an end dump trailer with low side walls. Besides not able to haul quite as much without side boards is there any other disadvatages to them. Concrete comes to mind as it has a low tailgate as well?? Reason I ask is im looking to buy a trailer and found this one for cheep. The price is right and I dont haul much concrete. Specs Hilbilt Excavator Frameless. air tailgate. newer floor. needs paint and brakes. new hoist and hose. tires 60%

a local shop that I bring my truck to get service done at gave me a good rate last year labor to install all 4 corners was around $230 I belive parts cast was around $400 slacks,shoes (no cores), hardware,s cams etc.. if you went to a dealer bring at least $1500!!! LOL

The air ride dump trailers that I have pulled were frameless and 1/4 framed, and get air from the trailer tanks to supply air to the air bags (just like dry vans do) I can say that an air ride dump trailer rides like a cadillac compaired to springs. Even if the tractor rears are on springs it does not hop around and make alot of noise or buck the truck around. They also seam to stop better and do not wheel hop as easy. some if not all air ride dump trailes should be able to drop the air bags down when you open the tailgate. this is big deal! if the air is in the bags when you raise the box it can go over real easy.! The only need for an extra air line from the truck to the trailer is if the tailgate or other air options are plumbed seapretly from the trailers air system. like the air over electric tailgates as there is no extra hoses to tangel. when I flip the dash switch for the tailgate. a electric valve drops the bags and opens the gate at the same time. If your real trick then you can use an electric tarp on a dash switch. (still have to clean the spread pan!)

another few truck pulls Boone county IL on thursday aug 9th 630 PM http://www.boonecountyfair.com/events.htm Wilmot WI for the kenosha county fair sat aug 18 http://www.kenoshacofair.com/activity.htm they bring loaded (pea gravel) cement mixers to this event and try to keep driveshafts in one pice. 6x6 and 4x6 set ups. some good carnage trent

how far did it pull that night joe?

My old RS did as I expected. It Dident pull great as far as who got 1st position vs last but I was happy as I was not far behind where the 300-400HP club finished. I have the fuel bumped up a little but I dont want to tear it up as the truck is a source of income and a hobby. We were hoping that "Last call" (the R685ST) would pull further than me as we had a big turbo hanging off the side of the engine and the local mack mechanic turn it up before the event. it came up 10 feet short of me wich isnot to bad considering it was pretty much an all stock 237. I think this turbo we put on is either to big to build boost or it was setup to run low boost on a larger engine? All we could get the big turbo to push was 10 psi and it sounded like it was working hard just not creating anymore boost? So we put a 350HP mack turbo on it last weekend and we now get 20 PSI. We will pull again next thursday and see if we made any progress. I put in a call to a local pump shop to see if we cant build up a spare 300HP pump and have some trick injectors made for the engine. if its not to much $$$ we may have some more tinkering to do

What is the APE# stamped on the fuel pump for . is it a calabration for a specific engine. We have a few old spare fuel pumps but have no clue what they came off of. We want to put one on our pulling truck. hoping one is a 300HP model Thanks trent

Brad thats a retired Tanzillo truck #5 That PJ his brother Anthony and I are building for fun and a few laughs. Mr Tanzillo was trying to sell it but he had no buyers for it all last year. So he gave it to us to mess with We tinkerd with a diffrent turbo before the pull but we think it was to big for the little 237 to spin as all it would do is 7 psi. The local mack mechanic turned it way up but still wouldent get the turbo awake. We put a 350 turbo on it from a truck in the yard tonight and it was making 20 psi so we might take it to belvedere (sp?) this thursday for a pull. Were not shure what a stock 237 turbo makes for boost anyone have a clue?? My truck pulled to 220 feet. spun the wheels all the way down the damp track. when the weight came up I stopped but the wheels kept spinning, tried to pull out of the hole in 4th low but the clutch said no so went back to 3rd low "Last call" pulled to 206.66 feet ..... slow out of the gate it started to wake up about 100' mark but the turbo dident want to get up. it powered out in 2nd direct Both trucks have a 6 speed an 4.17 rears. Maxville Trucks with springs get the traction but the air ride trucks can do just as well if they mess with the ride hight valves to over inflate them. There is a guy with 2 E9 superliners with lots of engine work that makes it to 290'+ almost every pull. The hitch is connected to the 5th wheel as seen in the pics. the hitch is 30" off the ground (adjusted) and the chains go to the bottom most part of the sled. Im not shure how much weight is transfered to the tandems when the weight is up?A friend has a 400hpE7 and a 12 speed he does pretty good as he has better gear selection than my 6 speed.Your E9 is a powere house just bring it to a pull stock to get a base line run, then if your not happy start spending mony on injectors and pump work, turbos etc... pick a gear that will get you to about 15-20 MPH if your cluth can handel it. dont pick to low of a gear as you will snap something alot easyer. Just talk to the other guys at te track. if like the guys i pull with they will help you. trent

a few shots from yesterday

lake county fairgrounds truck and tractor pull Friday the 27th located at Rt 120 and Rt45

Rob i was told not to grease up the bushings as it helps push them out faster? i wonder what others think? My opinion is that they should have some lube to help them wiggle on tight turns but thats just my .02 As for the caps i have seen them snap as well (on my truck) i just bought new ones as mine were worn from old age

I bought "mack red" from a local PPG paint dealer. if no one responds to this thread before i get back in town next week i will get the code off the my gallon can. i just walked into the store and they found the code for me. Trent

seen a few black legends but green seams the most popular

check the air lines first to see if they are kinked. If they look kinked or badly worn replace them. then look for a bad air cyl ( I belive the cyl is on the top cover?)that selects direct reverse etc.... If the cyl is good it could be a bad shift fork or bad rails again these parts are accessed through the top cover. My experince with air shift 6 speeds was that you would hear a hard grind if you selected a direct or low when rolling backwards or vise versa. also if I shifted to direct from low when rolling along it would grind kinda loud. at a stop the splitter should easly select the desired range with a soft clunk heard. just my .02
