NOTE: Before assembling the connecting rods, check without fail the elongation of the ring knurled screws. If the dimension X (38.3 mm) is exceeded, the connecting-rod bolts must be replaced.







11. Check the connecting rods. Determine the length of the connecting-rod bolts.


NOTE: In the case of the connecting-rod version with a 3-ring knurled screw, no replacement is possible. In this case, the entire connecting rod must be replaced. The 4-ring knurled screw is available as a spare part.


Identifying the ring knurled screw







NOTE: The visual difference between the 3-ring knurled screw and the 4-ring knurled screw can only be detected when the screw is pressed out.







1. Identify the ring knurled screw. With the screw pressed in, measure the groove diameter.
