OOPS!!!

Operator says he doesn"t know when or how this happened.

does he have ears? dang that sucks!!

Hate that when that happens !

I'd say he did not get much warning as part of the journal looks to be ok,it probably happened suddenly due to the rod cap bolts letting go, there is a 504BDT on diesel engine trader in OH for 3.5K,not cheap but that's this machinery business.

Got a customer that had a 3304 CAT engine, in a rubber tired loader, that had a slight top end knock. After changing injector nozzles, getting the fuel supply lines unblocked (new filters, cleaning nearly plugged line out of the tank, etc), putting in an air filter that wasn't clogged up nearly level full on the pleats, and removing the loose parts shaking around inside what was left of the muffler, I had 99.9999999% of the knock out of it. The remaing knock I simply attributed to a normal diesel knock, as that sounded like what it was.

Got done working on the machine and got in to move it. Put it in gear, reved it up to back it out of it's parking spot, and the engine decided to rev even more on it's own. All I heard was RRRRRRRRRRR...BLAM. When I saw oil all over the tire I knew there was a problem.

Went inside and told the customer I had good news and bad news, which did he want first? He said the good, so I told him I had all of the knock out of the engine. He than asked what the 'bad' was.....So, I told him that it had taken a hole in the side of the block about 'yea' big to finally get the last of it out.

Thankfully he knew the machine was on it's last leg anyway so he wasn't really that upset, and simply told me to go ahead and transfer all the new parts to the other machine so it woul maybe run a little longer.

A week ago Tues. I was combining along and without warning, after a bang, it got suddenly quiet. I shut off all switches, accessories, etc. I set the throttle and hit the starter(thinking maybe the machine has swallowed part of itself and plugged) expecting the 8.3 Case/Cummins to jump to life as usual. All I got was a little chug chug. And it wouldn't quit! Now I was afraid the starter was stuck in, wiring was crossed, whatever, and it was going to burn up! I jumped down, headed back, and saw oil all down the side of the combine. Got up, lifted the hood, and looked in to see a large "cut-away" view of the crankshaft turning. It was running on numbers 1&2! Number three rod was laying outside, along with a couple chunks of the camshaft, and block.
The throttle control was blown off with the side of the block.

Two years ago I did a 1450 B loader that kicked
a rod out like that. It was loading trucks, had
backed out to wait for a truck to back in and was
just above idle when it kicked the rod out with
no warning. Engine was no where near worn out,
bearings looked like new.

Looks all too familiar- mid 90s, 504 in a 2470 Case. Blew the rod out the side driving down the road. Retro-fitted a Cummins 855 into it- still running fine today. Way better than the 504 when it comes to power, torque, engine life.
