Rod bearing let go... nasty.

[Roo]

took 'ski out this evening, was out for 20 minutes before it completely just died. would barely turn over, and no starting.

from the start there felt like a *slight* loss in performance, but I had just redone some steering components so I was concentrating on that thought more...

got it back to shore and pulled up in my backyard, pulled the head off real quick and yep, this motor is DONE :frown:

long story short, bearing started to slowly shred, tossing peices into the combustion chamber through the intake ports, causing them to act like ping pong balls between piston and dome. things got HOT! notice he discoloration! sleeve cracked on two sides, rod/crank/piston damage, dome damage.

don't know what caused it ... gaskets look great, no bolts of any kind missing... good gas, tons of lube...

which route to go now... for what it was this thing was snappy! sucks that it let go in the of middle summer instead of winter :bs2:

summer saga:

-front nose peice ripped off
-battery terminals broke
-steering cable broke
-steering privot bolt broke
-driveshaft coupler broke

gotta get back in the water ASAP, summer is over fast :brap:

ill post the build when it starts...

some pics of the beat up 'ski... covered in sportbike stickers from my other money pit hobby of track racing. hides scratches and nasty gelcoat nicely.

Same thing happened to me. I little bit of corrosion on the inside of the rod where the bearing rests caused it to come apart. Looks pretty knarly.

Have the same problem with my ADA motor. I have been down for 3 weeks now. I was told that too much heat will cause the bearing carrier to eat itself and then the bearings will follow. I really don't know myself but If my piston looked as good as yours I would have pulled the chunks out of it and let'er rip.

[Roo]

Were you guys able to reuse/rebuild your crank, and just get new rods/pistons/sleeves?

Matt - no ******** man! i'll get back in the game soon enough... you guys are cool as hell, tons of fun to shred with! and help me out with douche bags on sit downs and dive bombing segals.

Anything? Update?

 

[Roo]

Anything? Update?

yep - completely tore the motor apart. bottom cases also have a nice small crack, and are nicely scored.

looks like some items of mine are going to get sent to Lehr tomorrow after i make a few more phone calls.

got everything down to a bare hull today for some treatment :sneaky:

Shooot. I blew a hole through my cases the size of a golf ball. You got off easy...however, that sleeve crack does suck. :bigeyes: You can probably weld up those cases.
