4.1.5. Attach the chain mounting brackets (6) to the sliding brackets (5) using four M10 x 30mm bolts (9). Use flat washers (10), spring washers
(11) on the nut (12) side only. It is not necessary to tighten the nuts fully until loading the gearbox support. The chain fixing (7) and the
chain hook (8) should be facing to the outer edges of the sliding brackets (5).
