Can somebody tell me the size of the nut that holds outer cam of peanuts on ch613

Any ideas, cant find anything obvious. Its an E7. Normally the code gives you good idea where to start, but 6 3 is too vague.

My 2001 CH613 used to do that, finally after about a month it started giving me a code. The connector on timing postion sensor was brittle and broke into pieces. As i hit bumps it would lose connection for a second and die, until that day when it finally came apart and wouldnt start back up.. it finally gave a code that day.

I have 96 CH613 E7 427. I am getting codes 6 2 and 6 3. The chart says 6 2 is turbocharger speed. 6 3 is J1708/J1587 link. it will crank and then die like its not getting fuel, wont restart. Have had trouble with connection on fuel actuator before so I went there first. I can unplug connector and replug, it will crank and then die. I realize its probably a bad connection somewhere, and idea where I should start.

You said the engine malfunction lights comes on. To get the code you turn cruise off and hold down the other cruise button untill the malfunction light blinks. Count the blinks, that the fault code..

All cents appreciated.

Thank you, rhasler. We are going to inspect them real careful. I have a couple of good mechanics, just in case one of us miss somethingm the other one might catch it. Thanks for your info, makes me feel like its worth the effort..

Ok I have the casting numbers. The 350 is 239GB5502M and the 427 is 239GB5518M. Help please..

I've heard for years all mack blocks are same. I've have block for '93 350 E7 had electronic injection pump. Now I have 98 E7 427 that has a cracked block, has same style pump. Can anybody tell me if I use block for 350 with all parts from 427, is this gonna work??

It was worn out plungers and barrels on injection pump. Had it rebuilt. Runs like a new one. Thanks for you help.

Rob, would you mind telling me how you mounted box fan to blow thru condensor. I would like to try that. This 105 heat index is tough, to say the least. Thanks

Pretty sharp truck. I have log trucks. Got a 98 with a 460 13spd 442 rears, the one I drive is a 96 with 427 13spd 464 rears. They are pretty much same. My 460 runs couple miles faster than 427. Blame that on rears. Good Luck to you!

Love my mack pack,but my first truck was 1995 Freightliner Classic. Drove it for 10 years. Never had any major problems with it, but I do know why they call em FreightShakers. Duct tape goes on long way on things that rattle till you get time to fix properly. A full roll of Duct tape sitting in floorboard makes a good coffee cup holder in a FL cause if you use the one mounted on dash, you'll get coffee all over everything.
