CATastrophe on a Cat 3516 Marine Diesel
 

Pics of the #4 main engine on the ship I work on. The #4 cylinder had some minor difficulties.:nshock:

Attachment 8609
Injector tip failed and sheared off...

Attachment 8610
beat the snot out of the cylinder head

Attachment 8611Attachment 8612
and the piston

Attachment 8613
which fubar 'd the liner

Attachment 8614
and cracked the crank at the journal....

Attachment 8615
which resulted in stripping the block

Attachment 8616
flipping the block and jerking out and replacing the crank....

Attachment 8617Attachment 8618
few more crank and block pics.

:pca1: dang thats alot of damage for an injector:argh:

yep..........alot of work just from an injector tip :ouch::ouch::ouch:

cool pics man

Either the injector piece or a chunk of a valve got ingested by the turbo on that bank (engine has two turbos, one for each bank of cylinders) and fubar'd it as well. The engine was basically totally rebuilt with all new liners, heads, turbo's, crank, etc.

:ouch:

Ouch!! :ouch: Bet that was a cheap fix

ouch, what caused the tip of the injector to sheer off?

looking at the pic of the head, with three valves messed up, I would bet a valve snapped, taking the tip out and the other two valves as well...... one man sittin in a chair, thousand miles away guess.

:ouch::argh: That is insane!!:argh:

what Ci and numbers does a cat that big put down? Considering some of the guys here have their 5.9's putting down Kenworth type HP and torque figures I'm a little curious and ya have any pictures of the ship that thing powers?

ouch

X2:ouch: ive seen that many times but on smaller motors

If I remember right the Cat 3516C marines engines are made to run 1600-1800 rpm( so they are a lower rpm application than the 5.9 Cummins) and produce 120-160 hp per cylinder. It has been A while since I have looked any of the paper work from the dynos but it seems like thats in the neighborhood I remember,

i recall 3516C being putting out 187hp per cylinder & being 4210 Ci

~3000hp rating @ 1650rpm

*edit*

Sorry, 3000hp is rated for a marine engine that has been modified in a big trawler here in Iceland

OEM is 2,350 bhp

Hey Chief, those are some great pics, but don't you have some z-drives to work on or something??!?:w2:

Hey, go make a round!

nice pics been a while since i have seen carnage that bad. hate to see the repair bill on that particular engine, we had a few 3508 powered 777 haul trucks and the repair bills were quite high when the engine had issues.:ouch:

it was still under warranty, so they avoided a big bill.

Hey Chief... I've seen way too many tips blown off on C7's. Being a FORMER shop forman for a Cat dealer. The great pic's that you posted, reminds me of why one needs to keep track of water in the fuel. Thanks for the pics....

wow.....that's @#$in serious git r dun right there........what in the hell does that thing push on water?

Found this while doing a search - sorry to bring up a REALLY old post, it amazes me that this was still happening - first time I saw this almost EXACT same failure was on a 3508 main in 1999-2000 time frame - it was a valve stem failure - dropped the valve and wrecked all types of havoc
