I went to the pete dealer the other day for some muffler parts and a speedo sensor. I was surprised how well the parts guys were there. Gave them a vin number and the guy rattled off the part number but doubled checked the computer just to make sure. I had not see a parts guy do that for years. turns out he has worked for Pete,IH and other heavy duty part companys for his whole life.

yep I had that happen as well . its annoying as hell!!! I had a IH with a stanless steel visor do the same thing depending how hot it was out. It even with the center brace installed. Made for some long trips out west in the summer time. And nothing made it stop besides if the temperature dropped. I put a bunge cord on it. stuffed tennis balls between the cab and visor. it just would warp when hot out and vibrate for miles.

I have driven trucks with and without them. I did notice the wind will make them flex if its real windy out and your on the high way.

I saw some pics of this truck on facebook.. Looks great. I remember seeing His fleet of R models pass by my neighborhood when I was a kid. I still live about 2 miles from his old yard in Lincolnshire.

The 5th wheel is a standard height Fontaine that I modified with a bar to pull frameless dump trailers. I never did get around to putting a high mount on so when I pull a Van trailer it is way too close for comfort and if I went thru some twists im sure it would make contact with the fender. If I recall a soda pop can is about the distance between fender and tire with no load on the truck. so yes a 4x4 block will fit between tire and fender. I think the springs squat down about 2" with a good load on it (stock 34K springs) On the truck is low pro 24.5 tires. the size is the same height as a 11R22.5. I never had interference with lowboy, flatbed or dump trailers. I only pulled a van trailer a few times and it was on road only mostly highway but they way I set the fenders up was to be high because the truck was being used for mostly On/off road use. At work im driving a Pete 387 and it has air ride. the fenders sit very close to the tires ....maybe 3.5" off the top of the tires and they dont rub but the axles dont move nearly as much as the Mack does. If I drop the air on the rears i can get 1 finger between the tires and the fender. all the R models I drove with springs were set up for real off road work. they all had fenders mounted higher than what was seen on air ride trucks.

here are a few more pics with trailers. The van trailer was empty you can see the pic with the low boy the front drives are up on the pavement and the rears are dropped down on the gravel.

same here . You will find that when doing this the fenders will sit higher off the top of the tires than say a truck with air ride. Also be careful with the clearance for the trailer bottom if you have a standard height 5th wheel. here is a pic of how high mine are mounted.(click on it to make it larger)

lots of cool pics in that album look at this one....is that Jimmy Hoffa?

found this on another forum... what is the wrecked 6 wheeler?

found this in the old picture vaults I have...

Fingers crossed...

Is this good news for Mack?

its in good hands!. Looking good Ray

I can't remember the last time I saw a u model tractor running around here. Plenty of DM roll offs though

Im currently driving a 378 Pete on air ride. When I pull the lowboy on air ride it's a smooth ride When I pull a 35' wrecking trailer on springs it bucks a little. When I pull a 24' end dump on springs it's like bob tailing on camelback. Air ride trailers make a huge difference in how smooth the tractor rides. The air ride simply takes the bucking out. I drove a r model that had the 3 leaf rear springs and a air ride end dump and it was a very smooth ride. No bucking at all.

Is Carry transit still around. About 10 years ago I think they were some how tied into or racing in the Champ car / Indy car series under the name sigma racing? I think they had a shop down on the south west side (bridgeview) that I would often bring race cars/ parts to. I remember going there and at that time they had a bunch of CH macks used for hauling tanker or bulk tanker...I think the early truck they used to haul the cars to the tracks was a CH mack as I recall it only had two 50 gallon fuel tanks. Not good for OTR trucking... they had to stop in just about every state for fuel.

Larry you have a 237... Glen will the water pump ,pullys etc...off his 673 swap over to the maxidyne ?

The 350s needed more than 5 gears to keep them in the power band. I think minimum was a 7 speed. You could however have the pump set to a maxidyne 300 spec and it would be fine.

is it my eyes or did they also stretch the hood on the V12 Mack? I can see they have some electric fans mounted to it. I suspect that V12 cat is really stuffed in there and they needed all the room they could get. Thanks for sharing

Larry why not put a 300 with a 5 or 6 speed direct? You can still find those 6 speeds laying around for cheep. What is your current rear end ratio? If its in the 3.xx you will have a 70 mph truck with a strong engine and trans... Regardless I think the triplex will be fine with a light load for all your hiway driving you do. It's the heavy off road lugging that people were more worried about with the maxi / 72 series transmissions. I think you will need a different clutch linkage as the B and R models differed. One is a push style the other is a pull style. Also the pullys up front on the engine stick out farther on the maxidyne vs a thurmodyne. Regarding the eBay link "300"..... It looks like a early 237 or older 673. Just looking that it's not inter cooled. The pipe off the turbo goes directly into the intake. The 285 HP were side mount charge cooled and 300 were front mount inter cooled..

Crack the injector lines open and see if it is spitting fuel.. That will tell you if it's pumping.

Please send more pics.....thanks

Drove a few R models with that style pump. 2nd or 3rd was what I used depending how heavy a load was in the box. I prefer the rear mount Mack PTO tho...

Looks normal to me.....

Look for simple things first ... Replace fuel filter, check that the throttle lever has not slipped around the pump shaft, make sure it has full travel...if that's good check for good boost pressure. inspect turbo for broken fins. After that you will need to start looking at the pump and compression levels...
