Well S4 engine locked up on a local club memeber.. and I picked up the engine to take apart and use as a display.. well the front half was perfect, apex seals were like new, housings perfect, rotors had no carbon build up, and looked as if it was reciently rebuilt..still had HYLOMAR on the side plates water seals.

Thats the rotor from the front.. uncleaned fresh out the motor.

Well on to the fun part..






There are alot more picture here.. 25 to be exact.

I don't know the story behind to the damage.. I sent a pm to the prevous owner of the engine and asked what exactly he was doing when this happend. I'll let you guys know as soon as I find out.. but for now.. I figure I would share.

I my guess is he missed shifted.. over revered and damaged the stationary gears, till it locked up.

 

Thats some of the worst damage I've ever seen...

 

Well coming from you, that means alot.

 

holy ****....

 

my sentiments exactly....

i doubt it was a missed shift, it looks like the motor had only been run for less than a few minutes, my guess is faulty assembly, how that is possible to get these results is beyond my ******* comprehension though.

 

One of my engines had stationary gear damage but ddaaaamn, that looks insane!

 

My friend just said maybe it was thrown in reverse by accident! what ever it was...it makes my teeth hurt.

 

huh what you mean thrown in reverse? while driving? in that case he would have broke the tranny if he ever got in gear in the first place.

 

my guess is that he put a brick on the gas pedal and poured sand into the oil fill or he drained the oil out the engine and held it at redline?

 

no, not sand. napalm

 

more like phosphorus...

 

ouch. That must have made one hell of a death cry...

I assume the housing was wiped out by the rotor too, judjing by the apex seal grooves being pinched/folder over shut. Dang.

 

that motor looks like it had less than a mile on it. Maybe he left the gear unbolted?? cant wait to hear the responce of the prev. owner.

 

ever seen a helicopter crash?

bad rotary deaths look similar to low elevation heli crashes...
i love it when i crash my RC helicopter but i hate the price i pay to fix it. parts flying everywhere! lol

 

Wow!!! Let us know what he says...

 

**** pentration happened inside that engine.

 

Wow... I want to know how that happened.

 

i bet thats a serious over-rev with horribly disgusting oil that hadnt been changed in 20k miles

 

Looks too new for that, the rotors didn't even have any carbon!

 

Anybody get a shot of the rear iron housing? I'd like to kn ow if the indexing pin for the rear stationary gear is still intact and in-place.

B

 

well as far as display purposes go, i'd say you made out well! there's a conversation piece

 

Fresh rebuild, start it up, floor it, ZoooOOOMMM, BAM!

 

 

holy ****...what the hell happened there...

 

Nice I'm so curious to know as to how that grenaded like that?????????????
