They couldn’t have got that wrong then ….. sledog Unless the dowel was missing no! there is a small possibility the dowel stuck in the fly wheel if thi was sent to the machine shop for grinding and was never put back in!

SLEDOG Posted October 29, 2022 Author Share Posted October 29, 2022 Still chasing original post I put new crank sensor in and I haven’t actually worked the truck to test yet. it does stall when cam sensor pulled and I’m led to believe it should not do that…. sledog Quote Link to comment https://www.bigmacktrucks.com/topic/70625-ai-460-cutting-out/page/4/#findComment-513985 Share on other sites More sharing options...

That said if Your original issue was not throwing up a code it is likely a main power issue that the ECU doesn't SEE as a problem! Relays as mentioned!

Joey Mack Posted October 29, 2022 Share Posted October 29, 2022 yes,,, there should have been codes for the RPM/TDC sensor... (Flywheel sensor) . at first I was looking at electrical/electronic issue. then i learned there was a flywheel housing failure. so i went on a tangent. I am back on earth, and think it is a electrical/electronic.. may be time to check the wires from the sensor to the EECU.. With a Fluke DVOM.. may be broken up-stream or shorted out. these engines can run on one or the other sensor, not very well but will run...

Use it to weed out the bad one if there is a bad one! Do this one at a time and try it! If after you have gone thru all 5 or six with no results then we need to look else where! If you run across one that corrects the problem then bobs you uncle! You have checked engine grounds correct?

SLEDOG Posted October 29, 2022 Author Share Posted October 29, 2022 I just got done taking grounds of and checking. Found a couple issues and wired grounds the way they are supposed to be.

Yup grounds are important ! an odd happening We ran across years ago with a brand new Etech in a log truck that would stop on a hill by the same cedar tree on the same mountain dog trail every once in a blue moon! Started getting quite frequent we consulted Mack and the took the same truck and duplicated the same problem on the Dyno and found it was Voltage spikes at the alternator at a certain RPM their tech happened to spot the surge when the engine quit at one point ! Just a stroke of luck if you ask me ! How ever we replaced the alt and it put a stop to the issue! Electrics can do strange shit! Dam lucky we could have search for that for months! Years! Comes back to what Onyx said experiences!

Onyx610 Posted October 30, 2022 Share Posted October 30, 2022 Electronics do weird shit especially when voltage is low. Think about all the times you had a vehicle do really funky things when the batteries were dead.

Joey Mack Posted October 30, 2022 Share Posted October 30, 2022 I remember in the beginning of this post, talking about grounds and the ACC. relay, and such.. If you look back to page 1 you will see.. so.... now I suggest you test run the truck, and come back with a 'Status update'.. this way, we can stay closer to the issue rather than going out on a limb for ideas, Like The way that I did, after I read about other issues... There are many guys here that give their knowledge freely, and want to know that the help you received was good, and got you back on the road.. Keep on Keepin' on.... jojo 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70625-ai-460-cutting-out/page/4/#findComment-514014 Share on other sites More sharing options...
Vmac3 Posted October 30, 2022 Share Posted October 30, 2022 To verify cam and crank corralation you need an oscilloscope. Another way is to remove both sensors and barr the engine over. The cam gear has two dots drilled into it. It's highly unlikely the cam gear would slip, otherwise we would be picking up engines pieces from the oil pan. Once the two dots are in view, check to see if the missing teeth on the flywheel line up with the crank sensor hole, if not rotate the engine again and line up the dots on the cam and recheck the crank. If they still don't line up then the ring gear has slipped. You will need a mirror and make room to view the cam. It's tight but it can be done.

Don't be offended ! I Brought up the Ground thing Up ! Because I noticed you had mentioned to check them earlier and to confirm He had checked this before wasting any more time chasing shit! Cheap And easy stuff first ALWAYS ! Just A little nudge! 😉 And SLED Keep us Posted Its fun for us to help and its satisfying to get the fix nailed down for us guys! makes it worth coming here!

Joey Mack Posted October 30, 2022 Share Posted October 30, 2022 Im never offended.. we all have similar approaches, and take time to remind the person, posting the question..

Popular Post SLEDOG Posted October 31, 2022 Author Popular Post Share Posted October 31, 2022 I think we got it now guys! Been driving for four hours now with no hiccups. Starts better too. When truck was in shop for broken bell housing they found bad stud on starter so they replaced starter. After that they could not start truck. They changed 135 amp ground breaker. They also left ground wire to frame and motor disconnected and ran there own ground from battery to frame and cab. I put everything back to original per prints. Thanks to all who helped, and a special thanks to Joey Mack! I know you told me to check grounds in the beginning. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70625-ai-460-cutting-out/page/4/#findComment-514165 Share on other sites More sharing options...
