I've changed my mind completeley on this being a Dart inspiration and go with KS assessment of a Euclid. I've seen Euc's that look just like this. KS to the rescue again.

Fjh- Yes the old Mack is dead but there are still plenty of old Macks around too enjoy. As for the new Macks at least they are still around. I'll bash Volvo all day but I still can't bring myself to bash the new Macks to harshly. They do have a lot more cab configuration options now with the new cabs. The only Volvo that I like the looks of is the Volvo VHD axle forward. Take care!

Mine had 2 rubber O rings that were bad.Replaced them from a standard O ring kit,that solved the problem.673 w/ turbo.

I was pulling a dump with marble chips when I lost the cold cap off the right side front duel and when it unraveled it took out the lines to the maxibrake it was a quick pullover about midnight and my flashlight soon quit working this was before cellphones and nothing around for miles away I crawled around and found enough fittings and with the tool box I always carried I got to sleep in my own bed that morning when I got home. Changed a fuel pump on a 3406 on the side of the road and two cummins water pumps on the side of the road countless water hoses and fan belts, fished a set of duels out of the creek down a bank when they parted company from the flatbed I used the Hyab boom to pull the tires up and used the boom to lift the axle up so I could chain it up the driver was impressed with my ingenuity. Got a call the duels on one of the walking floor trailers about come off and the truck was stuck at the rest area that dot used but they weren't working that day I walked the duels off the axle and used a bottle jack to lift the axel up to chain it and used my chain cumalong to pull the tires up off the ground and strapped them to the rear door I had the driver take the loaded trailer up to the next fuel station and we hid the thing out back and went back before light and snuck the truck back to the yard. I pulled the Brockway triaxle home from about 5 miles away with the F model Mack when I rebuilt the 318 DD in it I ran that dump for a few months it was pretty ruff but I was working on a fed rate job so I kept it running $17.65 25 years ago was good money from where I lived. Had a driver miss a shift on a very large hill and twisted up the front drive shaft I went out on call about 75 miles from the shop and found a phone to call the closes truck dealer to see who could repair the drive shaft found a shop and we got the shaft repaired in short order I helped the guy doing the work got back to the truck and the shaft was too long and now it's about 5 o'clock got the shop to stay open got the shaft in place after dark that night the driver hooked up to the trailer and no taillights and when I was screwing around trying to repair the wires up pulls a state cop and says I was watching you all day trying to get this truck home he says if you got 4 ways on the trailer and headlights just go home you guys need a break was the nicest thing a cop ever said to me

Thanks for the insight! I understand it's impossible to predict how long any part will last, but any info will help me understand more about the situation. And any tech tips, like the cam gear key advice, are most appreciated. I'm glad to know PAI is a decent aftermarket option. My dealership tells me that Volvo has completely stopped support for mack engines, and seemingly everything else Mack, save the name.

sell the Mack since it dont fit in there and get something bigger? 🤣

6. If it is a Volvo -- And it is on fire, fan the flames and let it continue to burn. .....Hippy

Hey everyone, One of the most stressful situations for any truck driver or fleet owner is an unexpected breakdown on the highway. Knowing the right steps can save you time, money, and even lives. Here's what you should do: Stay calm and pull over safely — Activate your hazard lights immediately and move as far off the road as possible. Set up warning triangles or flares — Place them at least 100 feet behind your vehicle. Assess the situation — Is it a tire blowout, engine failure, or electrical issue? A quick visual check helps when you call for help. Call a mobile truck repair service — This is where SRB Equipment's mobile repair units come in. Instead of waiting for a tow and losing hours at a shop, a certified technician comes directly to your location and gets you back on the road faster. Document everything — Take photos for insurance and maintenance records. Mobile repair services are a game changer for fleets that can't afford downtime.

no to the ceramic lifters. Without having a crystal ball, I cant say how long the current lifters will last. When your engine was born, the lifters had an issue where they would stop rolling due to a flat spot developing on the roller axle. they are brass. this caused the roller to stop turning and therefore it would damage the cam. With that said.... you have some food for thought on replacing the cam and lifters, or maybe just the lifters. If you do remove the cam gear, keep in mind you have an offset cam key, and its installation direction. For your HP. the white painted end faces forward. As far as PAI engine kits, I have built at least 10 complete builds and used many parts kits. They do a great job. I just talked to a guy whos E-7 Mechanical engine I did 6 years ago, and he is still running good. I have some out there that are older then that... Keep in touch.

Ouch. I think the book calls for a 1 mm. bead of RTV. Good luck..

What make of eight speed mack or fuller? terry

Hi guys I’ve been having issues with my mp8 with the egr. If I unhook the egr valve wire will the truck still run or will it go into derate?

I don’t believe they are available any more. The spring usually brakes inside the valve. unscrew the body. A diesel pump shop should have a replacement spring. Last time I did one I grabbed a few extra springs but who knows where they are hiding now…

I’m looking at a truck with a Mack 9 speed. Can I swap in an 8 speed in the same place. Is there any difference in length between the two?

Since a blown head gasket has led me to an in-frame on my 2000 etech 460 that has 1.8 million on the motor and 750k on the current build, I'm pondering changing the cam and/or lifters. The motor ran great and the cam looks good, but I don't know if it, or the lifters, have ever been replaced. I've read from this invaluable resource, bigmacktrucks.com and it's members, that the lifters can go bad and take out the cams in these motors. Are cam failures common enough to justify going deeper and spending thousands of more dollars? How about lifters without the cam, would that be a better idea? Or even just the eup lifters, as they seem to be the biggest problem? Joey Mack, if you're out there, I read a post from 2022 that said you were using a pai cam and ceramic lifters. Would you recommend that combo for the etech?

That is great. Congratulations.

I think I'm on the right track now. Thanks for all the valuable recommendations guys. I wish the last one in this engine would have had Joey Mack's advice used the silicone a bit more sparingly. It took half a day to pull the liners and I thought I was going to break the puller. They must have used a whole tube on that engine.

Learned that lesson for sure!

Excellent thanks for that …. Well on your way … bob

We made smoke today. IMG_1181.mov

Be sure you use ONLY ethanol FREE gas!!!!!!!

Thanks for the well wishes everyone, first day went well, here's to many more. Hope to see a couple of you at the truck show at the NC Transportation Museum in May!

Is this for American Truck Sim? I play that from time to time, with mods for Mack R's and Superliners of course. Definitely interested to learn more about this mod if so!

Since the Mack won't fit in there, might be a good time to sell it and get something a little bigger and stiffer.

He said "they only blow away if you close the sides in". And Zina said "we need to close the sides in". So they came back and closed the sides in.
