Boom....oh dear

[bru]

I just got back from my brothers after wheel removal for a pair of new Metzeler m5's on my RSV Mille, and his bike a triumph sprint in in his garage after a engine blowup, so i thought I'd grab a pic or two for your viewing pleasure....






needless to say he needs a new lump.

 

[Draeger]

That's let go in a rather spectacular fashion.

 

[Sagalout]

Wow, thos old T3 engines are normally bullet proof

 

[PU7E]

What makes an engine blow up like that, lack of oil or just old age?

 

[edd1e]

proper job!

 

[Glaucus]

Gaffer tape will Fix that

Good job, I thought I did well when a gudgoen pin, excited through the side, but that's a whole nother level on top off that.

 

[metbandit1]

That pretty damn good going!

 

[popovich]

A bit of duct tape and she's good to go.
Of course, you have to find the bits first. lol

 

[gillywibble]

Gutted

 

[eidolon]

Looks like it's been smacked with a lump hammer, good work!!

 

[Brackish]

Looks like me in the morning!

But wow I have never seen a bike engine like that. Could it be a chunk of road hit the engine wall at speed and it just went pop?

needless to say he needs a new lump.

He can fix that, tell him to see it as a challenge!.

I actually managed to repair a GSX1100E lump that was almost as bad as that, threw my GSX11 up the road back in 91, bounced it off the kerb engine first, mashed the crank cases, twisted the crank, bent all 4 rods.

Despite scouring all the breakers i couldn't source a decent lump to replace it, i did manage to track down a half way decent crank tho from a proddy racer, thanks to the good folk at SEP in Kegworth who moved mountains in welding & maching the crankcases, i managed to get it back on the road in about 7 weeks, would've been quicker but i broke my left arm at the wrist & elbow when i dropped the bike.

I presume a big end has let go? What I find surprising are the immaculately clean broken edges - no trace of oil. Has it been cleaned up with some kind of solvent since it let go?

 

[bloodiedathame]

My dad has one of these, how many miles had it done?

 

[wazza300]

looks to me like somethings hit it and took out the corner?

 

[lollyhayes]

looks to me like somethings hit it and took out the corner?

Yeah it looks like something hit it and weakened it, then it blew out.

 

[4T5]

Blimey

 

[helpimcrap]

peek-a-boo!

That is impressive!!

 

[VoG]

I presume a big end has let go?

Nah, looks like the crank & big ends still intact, it's the balancer shaft thats let go, that shaft you can see is the balancer shaft, which should have a substantial bearing & sleave sat on the end of it, which appears to have gone walk about in rather a spectatular fashion.

 

[Dogbreath]

I saw the balancer shaft, but doesn't it normally run a roller bearing on the end? The outer race and cage could have escaped when the casting broke apart; if the bearing had seized I'd expect it to be on the end of the shaft still.
