Standard

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).     X
 
 

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).  X    

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.     X  
  (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.      X  

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)    X X
