locked up multifuel 5 ton

[topo]

Sunday I went to get a load of water and had a tire go flat I returned home and changed the flat maybe 1/2 a hour I went to start the truck and nothing just a sound of the solenoid clicking but nothing turning . the next day I replaced the starter and the same thing just clicking . I tried tonight to turn the motor over by turning the drive line between the transmission and transfer case with the transmission in low and high gear and the transfer case in neutral and it won't move . I drained the motor oil and the forward sump I found two split rings I had to pull them out with pliers . there was no other sighs of metal could these have come off of some thing to lock up my engine ? I have charged the batteries and not sure where to go next .

The pic is kinda blurry but it looks like a coil from a spring. Any signs of water in the oil? Look under the filler cap.

 

[FireFighterHill]

To me those look like the rings that hold the Pistons to the Rods

 

[topo]

no water in the oil or milky oil on the filler cap . it is about as thick as a nickel and flat I though it was some kind of a snap ring . the bright mark was caused by rubbing some thing

 

[FireFighterHill]

I guess the correct term is "wrist pin retainer" at least thats what it looks like to me.

I will pull the pan and see what happened thank you Fire FighterHill

 

[FireFighterHill]

If you could get a better up close pic might be able to tell more. The ends of the ring between the gap are they square and uniform or jagged as if they were broken or sheered? Do the ends of the ring have small holes that you would use a pair of Lock Ring pliers to compress them for installation?

While I haven't had a multifuel apart, I can't help but believe that a multifuel wrist pin is bigger in dia. than a nickle. I don't think thats it.

Best thing to do is pull the pan and have a look.

 

[FireFighterHill]

Good Point m16ty

 

[topo]

the ring was just larger then the drain plug hole in the pan so it out of shape from puling it out when I pulled the other ring it came out but was not found . thank you for the help Kenny

 

[Floridianson]

Hope you find it. Could also take of rocker box tops and look see if you had a valve stick or drop?

 

[RANDYDIRT]

Does the oil drain plug hole look altered or repaired? The reason I ask is that that piece looks like it may be part of a Heli-coil that could have been used to repair the oil pan.

Today pulled the rocker boxes and the pan found the other ring still in the pan . these are the only two parts found .the top end is all where it should be nothing missing . is this what holds the wrist pin to the piston ? there was no other metal in the pan .

Here is a pic of the piston c-clip, as you may be able to see it has holes for your snap ring tool. I really doubt this is your issue, as much racket would have occured as this was ingested through the engine. A much more likely scenario is you left the ignition on, and you have hydrostatic lock, which is where the in-tank pump forces diesel past the injectors and fills up the cylinders. Pull your injectors and see if your LDS frees up.

Did you have the drive shaft to the rear ends out ?

thank you for the picture of the piston . I will work on the injectors next I would have thought that after a few days of seating if hydrostatic would have bleed out through the rings . I did not have the drive line out I had the transfer case in neutral . thank you both kenny

UP DATE the washer and split ring hold the idler gear for the oil pump on to its shaft . the gear can not come off the shaft it has been rubbing on the front cover and the oil pan . the end of the shaft has been damaged if I find these pasts in the pan again I will have to replace this shaft by pressing out . I pulled the injectors all good there . I pulled the radiator to be able to turn the engine over it turned fine . I put every thing back together and it fired up and runs fine I also took the ground cables off and cleaned where they mounted to the frame . they may have been my problem all a long . Kenny

Hah! I just fixed that issue before Haspin! You didn't put on a new bearing?

 

[topo]

no new bearing . but I will never try to turn a engine over by turning the jack shaft with a pipe wrench it's best to pull the radiator and turn the crank .

Not says the TM's but if you want to go to all the trouble. I rather waste my time changing out the air in my tires.
