rasnodgrass Posted April 20 Share Posted April 20 I own a 1962 B61T with an endt 673. Shop was idling truck checking for air leaks when motor shut down on its own as if you had shut it down. No type of unusual noise noticed. When trying to restart would not crank over and battery terminals became red hot. Further inspection determined that something had locked up everything including the drive train. Tried pulling but rear tires were locked.Any suggestions or advice would be greatly appreciated.

Joey Mack Posted April 20 Share Posted April 20 So you pushed the clutch and it won't roll, or turn over?? Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-574141 Share on other sites More sharing options...
rasnodgrass Posted April 21 Author Share Posted April 21 I assume the guys at the shop did but can't say for sure. Just know they tried pulling it after the starting attempt failed and rear tires would not roll. Not sure if clutch was depressed Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-574145 Share on other sites More sharing options...
Joey Mack Posted April 21 Share Posted April 21 if it was out of air or the brakes not released, it wont roll.. sounds fishy to me... 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-574146 Share on other sites More sharing options...
mechohaulic Posted April 21 Share Posted April 21 anyone check to see if engine had oil i it. engine seized ?? a diesel will not just shut down without cause, thanks JoJo , checking for air leaks with engine running ?? normally a mechanic will put shop air to system so as to listen for leaks . hope this shop is reputable / not looking for a customer screwing.

rasnodgrass Posted April 21 Author Share Posted April 21 I appreciate your input. I will check on this with the shop. Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-574155 Share on other sites More sharing options...
mrsmackpaul Posted April 21 Share Posted April 21 Try turning the motor over by hand, socket and breaker bar on the bolt on the front of the crank If it has spring breaks/maxi cans, it won't roll when you tried to pull it Paul Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-574163 Share on other sites More sharing options...
h67st Posted April 24 Share Posted April 24 If it was just sitting there idling when it shut down and now everything's locked up, maybe the input shaft in the trans locked up. Or maybe like you say they don't have the maxis released and the engine's seized.

Popular Post cruiseliner64 Posted April 24 Popular Post Share Posted April 24 (edited) Theres a smell of fish in the air for me on this one.Surely a shop could find out very quickly if an engine had seized??? I dont think a shop would try to tow start a truck without enough air to relese the brakes......

Geoff Weeks Posted Saturday at 12:35 AM Share Posted Saturday at 12:35 AM I can't remember if it was Glenn or Junkyard Dan, who said a Spicer type clutch can tighten up if not locked ( lock tang not bolted in after an adjustment) to the point the engine can't turn? I have never seen it and have to think about what he was saying, something about it spinning the adjustment until the T/O bearing is jammed against the transmission. It would be a "reach" for me to think this is what happened, but if all else checks out, look in the clutch housing. I still think something seized in the engine, but none of us were there when it happened. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-575040 Share on other sites More sharing options...
mowerman Posted 16 hours ago Share Posted 16 hours ago Really never even wanted to comment on this one …. Was hoping for an easy fix…. I should think you would’ve heard or seen or smelled something weird before it quit…. Best of luck ..: bob Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-575115 Share on other sites More sharing options...
Joey Mack Posted 15 hours ago Share Posted 15 hours ago This is an odd one.. Is the transmission stuck between gears , and the clutch is out of adjustment so it's locked up ? Did it just stop running or slowly die out ? Was it loading with fuel and it hydro locked? Im grabbing at straws....

fjh Posted 11 hours ago Share Posted 11 hours ago If it were hydro locked you’d think you could go backwards with the bar if it’s solid it’s likl engine! Didn’t read the whole post mind you!

Joey Mack Posted 11 hours ago Share Posted 11 hours ago Bud, i dont know what to think. Without trying to be a jerk,, My very first thought was that this shop doesnt know how to work with a truck of this era.. a computer truck would have shut itself off. Todays new diesel guys arent taught abought mechanical diesels because the time to educate that is time that can be used to get them to be good with a laptop for diagnostics. The new guys dont know any better.. Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-575121 Share on other sites More sharing options...
mowerman Posted 10 hours ago Share Posted 10 hours ago Well, there’s a lot of them around. Unfortunately, most of them need to be gone through. He might be lucky. Maybe one hole froze up on him. Parts are out there. You just have to search a little bit. Good luck. Hope it’s not anything you can’t handle….

rasnodgrass Posted 6 hours ago Author Share Posted 6 hours ago First of all I want to thank everyone for their input and suggestions.Sure appreciate it. Couple of updates. Oil was drained and found to be clean with no metal detected Starter removed and still would not turn with bar on flywheel. And bar and socket was tried on front of engine. Truck is at a body/repair shop that also changed air lines all hoses and belts. Not truly diesel mechanics. Yes the truck was just idling out of gear and shut down like you had manually shut it down No unusual noise or sound. Would not turn over when attempted to start. Locked. I was not familiar with Hydro lock till it was mentioned in this post. I understand water through the air intake could be one culprit to cause hydroloc. The truck had been parked outside with the air cleaner off due to body work and we have had rain. Now I wonder if this is a possible cause. Any input would be welcomed.

mrsmackpaul Posted 1 hour ago Share Posted 1 hour ago Depending on the amount of rain, would say unlikely for hydro lock However it is possible, especially if were it was unlucky enough to have the aircleaner fully removed and the down pipe running into the motor However I believe it was running, and just stopped while running so to me that rules out hydro locked Paul Quote Link to comment https://www.bigmacktrucks.com/topic/75440-1962-endt-673-will-not-crank/#findComment-575139 Share on other sites More sharing options...
