Normal wear (<2 mm)
|
The wear is less than 2 mm/0.08” and the difference between the minimum diameter and the maximum diameter of the lug holes are less than 1,5 mm/0.06” (oval shaped hole). |

Uncertain wear
|
If it is difficult to measure and the estimation of the size of the maximum wear could be more than 2 mm/0.08”, use an X-kit. The kit covers 0-4 mm wear. (The difference between the minimum diameter and the maximum diameter of the lug holes should still be less than 1,5 mm/0.06” (oval shaped hole). |

Excessive wear (2 -250mm)
|
When the wear is large - more than 2 mm - and known, the standard sleeve can be replaced with a specific size. Depending on size of the system maximum reccomended oversize system varies. |

(The difference between the minimum diameter and the maximum diameter of the lug holes should still be less than 1,5 mm/0.06”). if the ovality is larger grind back to or less than 1,5 mm/0.06”). Then install oversize sleeves directly into the prepped bore. |
Any wear but retorque to settle the sleeve is limited or not possible
|
Reduce the need for retorque. Line bore the lugs (also very little wear, less than 2 mm/0,08") to a straight and round hole and use larger sleeves that already fit perfectly in the bore from start. No need for welding and/or boring to original tight tolerance. |

Wear in lug bushings
|
If the lugs have bushings installed, remove them and order a matching size sleeve. The oversized sleeve replaces the bushing. (Expander System should always be used without lug bushings. If the original system have lug bushings the Expander sleeve is standard) |
