Did you replace all the orings ect on the return line tubes ?

Bro For Me as being an employee of a mack dealer We go out of our way to be compeditive on those type jobber parts you speak of And Im here to tell ya (some) of that stuff sold is shit. We got into that jazz for awhile selling no name reman and other (new) parts And Me And the rest of the Guys in the service were all over the parts guys to change back to buying parts thru the Parent company!Theres at least you will get a warrenty with the stuff you buy and the quality tends to be some what better. The jobber stuff on the other hand tends to fail more often and you get to keep both halves when it breaks. So the next time you see somthing so cheap sumwhere you can resist remember the old saying Theres likly a good reason. Not always but some times. Also remember part of the reason the captive parts aer so high is the fact that the consumables are being exploited by the jobber types and the dealer has to keep the doors open some how! The profit on those consuables is narrow in part due to this exploitation.So theres no place spread the pain. Just an opinion

Nope your the pig! You will lkly have to by a Head for the compressor the whole thing is over a grand up here! the Head is 400 500.The compressors rarly fail the heads fail a fare bit!

Yup put the rush on that if its still under warrenty!

We use to open up All the thresholds related to rpm in the customer programing to max that is the best you can do it is pretty much imposible to get max horse power where your wanting it and have any torque to go with it !

The Maxidyne engine is 3 times that little Cat engine depending on its treatment the engine will be the least of your worries! Dm is a very tough truck again depending on how its been treated will do what ever it is asked to do! If the price is right do for it!

SOOO ! Did 68 get this Data file in and did it Fix your issue???? Thanx

The LDA will repair the smoke problem to some degree but maybe not the power. Glad ya found the problem Maybe?

Thanx found the head torque 160 ft pounds you gave me the lash,So I'm good to go thanks. May get this puppy running next week!

Hi Guys Need some specs AGAIN ! I got Chucked into the middle of another job of the unknown variety this little unit it is a street sweeper Euro Ford cab !It got over heated and the head cracked so I / We are replacing the head. Has any one got specs on a 170 horse Ford/ New holland six I need the valve set specs and head torque for this little unit it is a street sweeper Euro Ford cab ? Thanx Fred

Let Us Know if this data file thing works Chuck I got a customer that has a similar issue. Thanx

Hope Hes Right!

Yup check for leaks or the turbo your way down on boost!You need to preasure up the intake side of the engine with at least 20 psi to fined leaks properly how are you checking it?

Yup Black smoke on excel

He quoted spec.s, All is good!

Don't quote me on this but with some horse power changes the cam key must be changed yours my be one of these!

See Chuck No Problem there! Were here for ya BUD !

yup that guy made enough money to take a Vacation! Why don't ya drop up my way Chuck I need a vacation! How bout you Rass ? you could use a week in the Sun couldn't ya!

If you unplug it it will code out! The valve is controled by the flow in the mass flo tube the valve really only goes where its told to go the computer does not know if its getting there or not!It would show up on the advance display in diagnostics as not reaching target but won't throw a code for it! put the block plate in, that 68 made ya and try it! If it is the egr valve your floating boost will be gone!

simply put an air switch on the supply line to the limit relay

If the spring idea don't work my best guess is the egr valve sticking! They can and will stick and not code out

Yup What He said!

It looks like you used the old lever, Replace the throtle lever on the side of the pump if the springs re worn it will surge and not return correctly!
