Cl713 likly has a Cummins in it! Check the rear output yoke for tightness! These were quite an issue behind the Cummins ! If it’s tight remove the top rear shift lid and check the shift fork bolt ! If it’s tight then the back section of the trans may have to com off and neew synchro plates installed!

Ahh I’m a bit out of touch on lumber prices i I just pull up a log and make my own stuff! 2/4 2/10 2x 8 cost about a buck a foot to make including fuel and logging costs! Not wear and tare on the equipment thou! And me!😞

Yup good thought Joe ! That said had this happen many times ! Shit got in the injector on installing of the line just my observation! AC engine particularly bad for this because of all the crap in the way !Replace the injector! Good to go! Cylinder not getting fuel! just sayin!

If you have bad compression I think it would be smoking! Do you have blue white smoke or excessive blo by? if not go with the bad injector theory!

does the engine have an engine brake?

The ground breaker can simply be by passed to get out of a pinch! Also if it does turn out to be the relay ! Make sure you’re given a constant duty relay cole Hersey is a common replacement and they make both and look identical!

i second the relay

yup another smart move in the name of saving a few pounds! At least they could have keyed these, Nope!

Kevin posted this years back sheds some light on the relationship! The mack V8 was molded around the scania V8!

Wow never seen a mid liner in a rd! Seen a fare few scania engines back when scania was associated!

TLC is EVIL!

the bottom oring has been deleted its a not necessary oring the only orings needed are the ones that seal the fuel from getting out of the steel line and the top oring to keep the oil in the engine! I have seen the older injectors used that has 3 oring groves on the return they deleted the bottom oring ! as Joey mentioned the groove half way down the injector is an assembly point!

yup start at the beginning ! the primer getting hard is odd there should be fuel returning to the tank at that point!

The Mack store will give you a blank stair unless you happen to run across a parts man in a wheel chair and hearing aids ! 🤣 Appears to me someone has put in an extra check valve on the fuel return under the stop lever there ? remove that number 6 line fuel should flow when you pump the primer up! The other thing is stick your finger in the hole where the pump came from and feel around in there I have seen this idler gear fall off ! it is held on by a c clip! it runs off the governor drive! I have also seen this gears idler shaft so worn the gear flops around a lot I would usually check this if I have a pump off as you have there! I really sounds to me like you got a restriction on the inlet side from the tank! By what your describing!

Not a Guru! An observation! How ever frost on the elbow can indicate a low charge ! Should be sweating a little just a bit damp!

wouldn't happen to be a 4:17 or 4:42 ratio would it ! ? couldn't hurt to check both diffs! just saying!

Second that Joey ! I have saved a lot guys swearing they had a trans problem , from spending big bags of money by simply looking at diffs first before taring into tranys as they have wanted!Go with what you know first!

I think judging by what you have said here the injector got some shit in it on install rust or or something the injector is fouled!

bar the engine over till you see the hole in the adjustment hub in front of the gear on the pump dead center in that opening and then check to see if the timing marks are any where close to the pointer! if the timing is within the numbers on the damper your timing is close enough to run 17 -24 ish! if the timing marks arn't close pull the compressor and and check the gear same with the power steering pump!

Pull the cap two screws right front that will expose the rack clean it first as mentioned!

So i am confused you took out an auto and are replacing with an auto? or took out a standard ? Just mentioning a clutch switch jumper if the standard was removed!

yup thanx for following up with the fix !

Most of the engines are fairly quiet these days ! Detroit 60 is quiet as well ! Exception being the x15 in my opinion sounds like it may fly apart at any moment when taking off from a stop loaded! thought it was a one of thing, but they all sound like this Very curious why! May be a compressor sound or fuel sound duno!

pull the VECU from under the dash and check the plug to it these sometimes get water in the plug from a leaking windshield!

Nope the cam gear is a shrink fit on the shaft ! Unless you have a hefty puller it isn't coming of in frame! the cam code may have to due with front cover flexing check it closely for cracks seldom the issue how ever worth checking! make sure your motor mount id in good shape!
