Just Finished a V8 build in January We used PAI kit Very complete kit Half the price of the mack stuff and twice the warranty!

There intent is to make the old mack stuff unreachable buy pricing it out to lunch make it go away ! The dealer is only part to blame their pricing to the dealer is ridiculous as well the dealer is just passing the gouge on! Look else where! Best aftermarket mack parts is PAI in my opinion! excellent pricing compared to the volvo criminals Even for MP and volvo trash parts. AND better warranty!

Yup me too however ,this being an intermittent miss makes me doubt ! vthings happen thou

Range fork loose or broken! Broken axle broken thru shaft

Yup 90s anything

your tool from the inlet sounds like it worked fine a 4 inch piece of 3- 4 inch exhaust pipe ( depending on your cooler) caped off and drilled and taped for 1/4 inch pipe thread and a pressure reg set to 40 psi will do the trick Good known gauge! you can also make the cap not drill it and back feed from where the puff limiter is installed ! once you ares sure its tight then we can talk twisting the dogs tale some more! Just some ideas to giter done!

For logging, you'll likely be looking for a CV713 AI460. Very sluggish power wise. Durable yes, powerful not so much!

That turbo should be putting out in excess of what you need to achieve good boost In my opinion ya need to leak check the whole system to the boost your expecting to run , We have an adapter to put into the After cooler on the turbo side and pressure up the whole system heads and all ya need to bar the engine around a bit to get the valves in the right spot to pressure it up or pull the rockers to close the valves .but its the ultimate way to ensure you have no leaks! Stock coolers tend to crack on the hot side top front! There has been instances where boost can be dumped out the Air drier Depending on how you gave the inlet of the compressor plumbed!! This can happen on the v8 as well but you would likely hear it unless your running straight pipes!

Do you have a pyro plumbed in what temps are you seeing?

It is a large solenoid beside the wiper motor that powers the cab accessories including the computers. Did you replace this sol???? Key to this is next time it happens check to see if the heater is blowing if the heater motor is not working the relay acc solenoid under the dash is toast its under the ash tray to of dash!

Yup how far off the floor does the clutch brake operate ? The clutch brake should be adjusted with the arm on the side of the trans or with the cable yoke It should operate RIGHT ON the floor 1/2 to 3/4 of an inch! Once that is established you need to have 1/2 gap between the throw out bearing and the brake! Free pedal up in the cab is only a rough guess ! Anywhere from 1- 2 inches! Adjusted on the clutch face 5/8 adjuster ! If its a auto adjust you are on your own! they are junk

Wow Im surprised you not having issues with that volume of air going thru that filter I've seen that rubber elbow collapse on the single under hood style with a moderately cranked engine 33 psi boost stock turbo! how ever that may have been a washed filter not great for use with a high volume situation ! The timing idea is a possible cause however the engine has been timed from 17 to 24 for different years and horse power ratings.I have had them not run correctly timed to the number stamped on the pump ! IE: at 17 stamped on the pump very retarded smokey bump it to 19 or 22 OK .! In reply to the original poster, as mentioned you might bump it beyond the pump setting and see if it steps up the game a bit!

Check for boost leaks! are running dual airccleaners? doubt the under hood single will handle the air you need to have well

Yup what he said change it

are you seeing smoke under load? If not check the throttle linkage make sure it's going full on and your getting full stroke 30 is stock boost

They kept only few select things which they charge the the nose for , the mack diffs and the tranys, and some suspension stuf the rest is rebadged Volvo trash ,any of the well engineered mack ideas were tossed to the side of the road and buried.

What type of clutch?eaton pull clutch? 14 inch 15 inch?if you need help please post clearly what your working on?set the clutch linkage so you got a bit of clutch brake first and then adjust the internal ring so you got 1/2 to 9/16ths space between the throwbearing and the brake! If it's Eaton

Is there any way you can build a test gauge to test fuel pressure needs at least 60 psi or better Under load to pull decent run a temp line into the cab with 1/4 plastic line! also have some one check the ambient air temp sensor if its running an odd number the computer may be being duped into thinking there isint enough air to burn the fuel properly!so its holding back!

Correct?

Wet Sleeve for sure!

Yup keep us posted thats what makes it better here!

So this is the the truck that you have been having the pulling issues with? Your posts are rather Vague Bro ! You need to provide info here if you want help! Check the air cleaner take the inlet off the turbo and check the wheel and shaft for movement if these trucks are new to you you may have the wrong muffler on or the muffler could be falling apart inside!Are the engines mechanical or are they electronic!

Engine brake stuck on?

yup with out fuel legal with fuel not so much!

Kev, they showed a bunch of stupid people. That must be the target market! OH WAIT! They are promoting a Volvo! Kind goes without saying.
