hi all I have a 89' silver top td42 in a gq and am wondering if anyone can tell me for sure if it will have the 28mm gudgens or the 30mm

thanks for your help

gudgeon pin hole diameter:

27.992 – 28.000 mm

November 1989 on

27.997 – 28.005 mm

gudgeon pin fit in piston:
- 0.008 - 0.007 mm
November 1989 on -0.003 - 0.012 mm

Gudgeon pin oil clearance in connecting rod 0.025 – 0.045 mm

Piston skirt to cylinder bore clearance:

Factory cylinder liners 0.05 – 0.09 mm

Service cylinder liners 0.09 – 0.13 mm

That is awesome thanks. So which ones have the 30mm ones or have I been mislead about that

later ones with zd30's etc.

oh cool thank you
