2004 G22 engine pulley removal

staufson

I recently purchase this car from an auction. It was missing a starter generator which I installed and it cranked right up! It ran maybe 50 yards before it started making a clanking noize in the engine and then it ceased up. Oil was up to normal levels before I ran it.

After taking the engine out and pulling the piston cover I found the piston arm had snapped at the rod. Any idea what could've caused this. The rod looks to be in good condition. I am now trying to get the engine pulley off and I've tried everything from a puller to a longer bolt to pull it and even wedging shims behind it. I have noticed a hex head screw deep in the shaft. Is this the solution?

Thanks in advance!

There is a special pulller bolt to remove the primary clutch sheave!! About 40 bucks!!

Or take it to a Yamaha dealer, and have them remove!!

Got it off with a make shift puller, pb blaster and a rubber mallet. Does anyone know what the small pump looking device is inside the block is. It has a a single wire coming out of the block. It wasn't connected and I'm thinking that's what caused the piston arm to break. I think it goes to the starter generator.

Thank you for the response!!

If it's the blue wire, it's for the low oil level switch. All it does is turn on the light.

That's it....any other ideas why the piston arm would break around the shaft? I'd hate to get it together and it do it again....
