Install And Weld In Wheel Well - Ar62.20-P-1200-17LF

Model 217 

Model 222 

except code Z07 (B7 armoring on special protection version) 

The following steps are shown on the left side of the vehicle and must be accomplished analogously on the right side in the event of damage.

When MIG welding ( ) prepare welds by grinding down to bare metal with stainless steel brush. Tack weld seams at start and end. Weld seam gap should not be greater than 1 mm, if required, preweld.
