AZB755V8

I got a set from Ebay. Mind you that I like Mack parts but thats what I am replacing torn Mack pins. The quality is good they have a bluish color. They do work and hold the hood, what else are they suppose to do? The only thing is do not tighten them down to much as the pin starts to widen and will not locate the let the hood fall into place. Normal tightening is the key. I'll get them again if needed.

Frame looks a little thick to be a 613. My bets on a 713.

Looks to be in good shape to start with. Good luck and have fun welcome. I like the H in the back ground too.

I got a set of fiberglass fender flares for my Superliner from Australia last year. I like the look as well. Great flares but... bend over for the shipping. UPS charges dimensional weight. Parts where 5kg and $620 later in shipping they were state side. All said it cost $1000 for the flares and shipping. Had I known the shipping cost first I would not have done it.

I got a cut-off. 38k Camalback with 4.42s in Cleveland, Ohio. No air lock just simple Mack. Budds If you have Camalback just swap whole assembly. $500 come and get it, cleaning out the barn.

First time posting photo, hope it works. many to follow. Air throttle springs for E9, inline pump.

That's a smokin deal on on that 300 & 6 speed. Put it in and GO. Pull clutch and air filter would be the big issues. Bet you could get the front mount and not have to swap engine parts. Think it has a wetline pump as well that's worth $ too. Definitely go with the paper. Don't take a chance with the oil bath. Those oil filter went by the wayside with the increased HP for a reason....

That is Dan Thomas's Aussie Valueliner. It original done to the paint and Steering Wheel on the "Right" side. He's got a long, long distance award if there ever has one. Not to mention he is based in Oregon on the West Coast, USA.

Can't say I have heard of a factory 711 Turbo?? All those old turbos made only a few pounds of boost but good for a lot of smoke. They where just plain big as well. The 250 or even a 237 probably does have more power than any 711 did turbo or not.

Lookin at your profile page you have a 1005 which is a early E9. I have both 866 and E9's. My 866 has the large head bolts and the E9's have the small but mine are 1990's vintage E9's. The fact is that your engine has been worked on and has a mix of bolts. Mack is know to change spec at any time. Looking in the overhaul procedures manual it looks like both sizes of head bolt were used on the E9 but only one torque spec. That indicates the same size bolt but with a different head size. Head bolts have been a problem from the beginning and should be replaced when the head is pulled. The small head bolts are the only ones listed now. I wouldn't worry about it until the head is pulled the next time. Don't fix it until it's broke.

Small are the correct ones

Definitely not factory on an E9. Looks like it had some head work done and damages the head bolt threads or broke bolt. Instead of Helicoil insert they taped it to the new larger bolt size.

Well for reliability?? Do you trust stopping every time you hit the air brakes? Same air and cylinder concept as brakes. It just seems a little mushy to me and lags compared to a cable. No real snap... Think there is a air restrictor to slow pressure build-up. If you have a diesel pick-up truck built in the last 10 years your pedal is not directly connected to the pump ether. I went to work on my kids car and the throttle is actuated with a motor and not connected to the pedal at all. There's a switch on the dash for "sport" mode that doubles the movement in the throttle motor.

I believe the air throttle came out with the inline pump around 1990 or so. I don't think many guys liked it but it was suppose to saved a lot of broken drivetrain parts. Even with it the 94 CL I got for parts had clutch, trans (twice), drive shaft and front diff replaced by 400K miles. The E9 is still in great condition though. An E9 is a one driver engine not just give it to the new kid to learn on.... unless you want big broken parts.

1978 the E9 was in prototype as the 1000 and 1005 and not intercooled. In 1979 the intercooled E9-400 went into production and ended in 1999 with the E9-500 in the USA. The engines pre E9 where the ENDT 865@325hp Maxidyne and ENDT 866@375hp Thermodyne. Both were not intercooled. Produced between 1970 and 1978.

The B-75 that I started with back in 96 came from Midland Texas and was the same color. I have seen 4-5 of these off green color trucks for sale over the years.There was a oil field fleet that had these trucks. Anyone know what was the name of the company?

I just restored the tanks and straps on my 53 LTL and used the lace from the same Restoration Specialties. It is as close to original as you will find, good quality and color. If you have the split rivets holding it to the strap they are in the bolt section at Ace Hardwares. Use the spray 3M Super 77 glue to hold the straps in place as well.

The gain in CFM's in the headers is really understandable but all the exhaust still has to go though that little approx 1 1/4 x 2 inch port into the turbo from each side of the engine. Gas velocity is low in the headers and has to accelerate in the crossover tubes and into the turbo. High velocity gas is what spins the turbo not volume. Headers work by scavenging gasses out of the cylinder. This can not be done with back pressure from the other cylinders pushing back on the exiting gas as in a turbocharged E9 engine. Maybe at 4000 RPM's or more but there are just a handful of E9's spinning that at truck pulls. I have raced and had headers on things for 35 years and still do. They don't work on anything until 4-5000 RPM's. I've went back to manifolds on several vehicles and picked up torque and hp at lower RPM's where normally used.

I got an old Holset H5, made before all the billet stuff, its good for 60-62 psi. I have Francis do one now for me. $2300 out the door, my old one was $2800 ten years ago. Be careful to not go too BIG. The Holset is a 3.6 with G trim and comes on at 1800 rpm's. Anything BIGGER is strickly truck sled pulling material and needs a lot of RPM's to spin it and not usable for everday. I want the new one at 1500 rpm's to make it a little more usable for the road but still pull like a freight train! Still a 3.6 but with different trim. I just put on a turbo blanket and wrapped the crossover and exhaust under the cab to keep the heat in the pipes. Any one else noticed a difference doing this? It sure helps keep the floor cooler.

That's a Sweet Fleet plus spares. Hope they go to a good home

Prices, photo?? What is the scoop on the E9? V or Inline pump, Miles, hours, last run? Oil pressure, blow-by out the breather?

Got a radiator out of a 94 CL700 for my Superliner, both the same size and mounts. It has the big intercooler and under it is the AC condenser. I kept the AC condenser to use when the Grilldensor goes bad. It's right from Mack and is protected behind the grill.

I was thinking of log manifolds for one of my projects. I've had leaks as well but did not see what tube headers would do besides make a lot of under hood heat and have to be wrapped like Mack Doctor Jr said. Has anyone looked into square or rectangular tubing. If someone made up sets would there be interest in them and what would they be worth?

I don't understand what headers will do better when installed on a stock engine. If this is about the supply of manifold parts being gone and the only solution is header I get it. I have two Hot E9's one at 1100 plus HP and the other 1250HP both have cast manifolds. Each has work done by Dale Francis and Steve Trivets but I do not see a need for headers even at over 3500 RPM nor did they for this power level. Headers look nice but for stock 1800-2000 RPM I think they would decrease power rather than make more with a stock engine. If I could get 50 plus HP or more I would consider a set. What am I missing? Tubing comes in several wall thicknesses and can get pretty thick. Racing headers are normally on the thin side. Thicker would be better for longevity in a truck.

Saw a post a short time ago. Talking $40K then.
