OEM Piston Wrist pin Bushing - Too small !?

[Nicko500]

Hi all !

I post here because I have a problem with wrist pin bushings bought from Z1 (so it is oem parts)I placed them into my OEM rods, they fit without any problem.

But today I tried to fit OEM piston pin into them.Impossible ! Even with heating them.

I can measure new bush inner diameter at 21.865mm and old at 22.005mm

So what happened ? Wrong size ? Somebody already replaced Pin bushings ?

Thanks for your help !

Finally few days after Z1 replyed me that bushings must be honed !?

Someone can confirm ?
