Connecting Rods are firstly dismantled, chemically clean and then visually inspected for serviceability. Non-destructive magnetic particle crack testing is carried out on all rods and caps. Close inspection of the overall condition of the rod and the rod cap and mating faces is carried out. Additional checks include checking the rod for bend and twist and comparative length against its partnered set.
The connecting rod is then reassembled, bolts are tensioned so that all critical measurements can be taken and recorded and compared to the OEM Specifications. Connecting rod tunnel resizing can be carried out were the rods does not fall within the manufacturers tolerances for reuse. Small end bushes are replaced as per the manufacturer’s guidelines; this may include press fitting and broaching, induction heating or liquid nitrogen cooling of the bush. The small end bush is then pin bored to ensure the correct clearance between the bush and gudgeon pin is achieved.
