👍 ok, so is the engine gray or red? My response is for the gray Engine..

That Nails It!!!

The year and model dont jive, however that code is "Engine RPM" The sensor in the flywheel housing, right where the clutch cable is mounted... Un plug the Cam sensor, and try to start the engine. if it doesnt start, the fly wheel sensor, or wires, etc. is bad.. jojo

Has this engine been over-revved? I know..... Dumb Q because no driver will admit it, however, a bent valve can do this.. of course we need to look at the simple things first. I use an inferred temp. gun often to help point to a bad cylinder. It's not fool proof, but if you see a large difference in cyl. temps on the exhaust manifold, high or low,, you can find the cyl. to look closely at.. yes 3+4 will be hotter, but .... anyway... you get it... jojo

Riveting, hard hitting, and precise news coverage!!! Thats a good one.... Keep e'm comin. 👍

several things come to mind, valve adjustment?? Engine brake (if equipped) hanging up??

There have been several times where Biden called her "President"... The amount of damage tat has been done to our country in the last 4 1/2 months is terrible. The workers in this country are the new "Slaves".

Very Diplomatic.... I wish we could hang out and have a beer or few... Jojo

What I cant understand, is that 155 million people "voted" in a country of roughly, 350 million.... The lib's fussed about racism at the pole's, by making it "hard" to vote.... B.S.!!! I should have looked up how many people are'nt old enough to vote, and, in jail, and not citizens..... So, my guess is... roughly half the country cant vote???? how do you get so many votes for the whole election? Jojo...

gaskets valve cover for 673
Joey Mack replied to davehummell's topic in Antique and Classic Mack Trucks General Discussion
P.A.I. makes parts for the 673. I have one in my shop now. I also buy from "AGKits.com". the book i posted was a printout that one of my favorite Mack parts guys printed for me. It's 125 pages.. It is loaded with part numbers, for almost all points on a truck... Joey Mack

you must be pretty good at reconditioning the EUP lines by now,,, 😄 -
Left of the clutch pedal on the triangular bracket with the 2" hole in it... If it doesnt work, its probably unplugged because they are annoying
-
I have never seen that square shape before.. I've been around decades of R's and RD's... is it some sort of R-700 hood?

2000 ch 427 hp low boost
Joey Mack replied to Mackvette1's topic in Modern Mack Truck General Discussion
It comes out of the side of the block, right side around #4+#5.. The 45 degree fitting is a regulator. 80-100 P.S.I. is good pressure. You can put a gauge on it. I have made a few adapters to hook into the fitting and still keep the fitting in place and if you have the fuel sensor in your fitting, making an adapter is easy. just "T" into it, and attach your gauge, and screw the sensor in to the "T" so you dont throw codes or cause any other ECM issues. jojo -

2000 CH613 light make gauges max out
Joey Mack replied to jab002's topic in Electrical, Electronics and Lighting
Grounds.... Pull cluster and clean the ground bolt to the left. It is a 6mm bolt, (10mm socket) If it has the star washer, remove it, buff the paint clean and scrape any heat shrink glue from the eyelets. Do the same next to the fuse panel on the right side. Then clean the ground on the left side of the engine block in front of the starter, also clean the frame ground bolt that is across from the block ground. There will be a #4 wire going from the block to the frame there. Then clean the ground breaker on the firewall that is next to the starter relay.. Good luck, Jojo -
there is a reversing relay on the the top of the intake manifold. It goes to the bimber valve in the front of the injection pump. Just check to see that the air line and fittings are good, sealed, tight,,, etc.. stay simple for a bit. The E-6 is a great engine... Go bull dog!

AC Compressor losing power
Joey Mack replied to ayoarod88's topic in Electrical, Electronics and Lighting
I had another thought. did you put gauges on it and see the high side pressure? if it spikes passed the High pressure setting, it will shut the compressor off too.. -
AC Compressor losing power
Joey Mack replied to ayoarod88's topic in Electrical, Electronics and Lighting
does it have an APADS module? and is it flashing a code? -

Is the evap core freezing up and shutting the system down? Do you see a good flow of water draining from the drain tray on to the ground when the A/C/ is on?
