Default How to remove a connecting rod?

I just blew a connecting rod in my V-Spec and cant seem to get the broken one off (from the pistion). Any help on this issue would be greatly appreciated.

Thanks

Alex

Hi Alex, the top end of the conrod is held on by the wrist pin, remove the small thin clip that is holding the pin in the piston, then push the wrist pin out and the top end of the conrod will come off. Hope this helps.

Take the tires off youre car, then fire up the engine. hold it full throtle for about 30 seconds. The con rod will come out all by its self.

Heres a trick, put the conrod and piston inside a large clear plastic bag such as on Ounce Bag

Then put you hand inside the bag with whatever tool you are gonna use and remove the clip cause if you dont and it goes "Ping" you will never find it again.

if you remove the clip and goes "ping", don't bother finding it. it is never recommended to put used ones back. use a new clip instead.

you're lucky you only blew the conrod. usually if the conrod blows at high rpm, piston n sleeve also goes with it. if conrod broke into pieces,you may wanna check all the internal parts...

when my conrod gave up on me, it chipped the piston that i had to replace the whole P/S/conrod set.

Yeah i ported out my sleeve and didnt replace the ROD that was worn, bad move and here was the result, Sleeve, Piston and Backing plate all got hammered.
It actualy blew up on the starter box at low revs too.

Small screwdrivers, picks, center punches, body clips, unbent paper clips, lots of cussing and swearing...

You don't need to take it out because the piston and sleeve are damaged. I would look carefully at the crank case & main bearing as well.
