2. New chain,
3. Intermediate link,
4. Outer cover,
5. Oil pump,
6. Pallet.
2. Disconnect the old oil pump drive chain 1. To do this, knock off the heads of the link bolts before removing the chain (arrow) (see figure 2.83). Using a screwdriver (arrow), disconnect the chain by removing one of the links and pressing out the outer cover 3 (see figure 2.84).

3. Attach one end of the new chain 2 to the old chain 3 with an intermediate link 4 with the outer plate 3 (see figure 2.85).
Figure 2.85. Attach the new chain to the old one.
4. Rotate the crankshaft slowly in the direction of rotation until it is possible to disconnect the old chain and connect both ends of the new chain.
5. Disconnect the old chain 1 and connect the ends of the new chain 2 using a new intermediate link 4 (see figure 2.86).

12. Tighten spindle 6 to 30-35 Nm. Rivet the intermediate link pins individually.
13. Check the riveting of the chain link and re-rivet if necessary (see figure 2.93).
