Cruzinimage GT550 crank rebuild kit

[Srxburns]

Hi,

I saw on ebay that cruzinimage has a crank rebuild kit that includes all the bearings and the seals to rebuild a GT550 Crank. The kit is $80, has anyone used these kits?

Thanks

Not seen that - it's VERY cheap.

Are the bearings made out of old tin cans?. At that price. I'd be very skeptical. Anything high quality can't be made that cheap.. Besides that, I'm still pissed off at them as their brake line was total crap.

That is kind of what i was thinking and being a crank is something that you don't want to fail with the labor involved taking it apart and rebuilding it. I read the pistons are ok so wasn't sure if anyone used this kit and had any luck.

I read the pistons are ok

Some yes and some no. Someone here recently bought a set of pistons for a 550. He said the wrist pins were sloppy loose -- just fell through the piston hole. Apparently there is no QC, and even if there is do they really have quality calibrated measuring equipment? What some people don't realize is this stuff is made in China, then SOLD through Japan.
I don't know about the bearings, but Paul Miller has the complete seal sets on eBay all the time. Suzuki stuff.

Yep, was me. My crusinimage 550 piston set has loose piston pin holes, whether I try the pins that came with it or genuine. QED the holes are very slightly larger than in genuine pistons. I don't know if it matters. I didn't use these pistons.
Oh, and they were all larger than genuines, 60.99 to 61.00, where the genuines are usually 60.96 to 60.99. Doesn't matter if you're reboring / honing but on on a plated cylinder, even if you've a perfect plated one slightly too small, you can't hone it for correct clearances and expect to hold it true, just too hard a surface (so my plater said anyway).
I'll keep as spares as genuine are a crazy price and, as said, I don't know that the tiny differences matter or not.
Cheers,
Mike
