Examination
1. Remove the cylinder head cover.
2. Turn the engine crankshaft using the crankshaft pulley mounting bolt and check the condition of the chain along its entire length. If the chain makes increased noise when the engine is running or there is a large axial play of the chain on the sprocket, the chain must be replaced. If there is wear on the chain rollers, the chain must also be replaced.
Replacement
Attention! When removing the chain, it is necessary to use an emery wheel or vulcanite to cut off the protruding caps of one of the chain links.
Removal the connecting link from the drive chain
1. Remove the ground cable from the battery.
2. Remove the fuel injectors.
3. Remove the radiator fan and shroud.
4. Remove the drive chain tensioner mechanism.
5. Using a clean rag, cover the cylinder head and chain in the cover.
6. Using an emery wheel or vulcanite, cut off the protruding cap of one of the chain links at the top of the sprocket.
7. Remove the chain link retaining plate, then remove the chain link from the drive chain (see picture).
8. Remove the rag, being careful not to allow any shavings to fall inside the drive chain cover.
9. Using a link from the new chain, connect the new drive chain to the old one and, while turning the engine crankshaft clockwise, pass the new chain around the sprockets and guides. At the same time, constantly tighten the new chain so that its links are precisely aligned with the camshaft sprocket. Also, constantly maintain tension on the old chain to prevent it from falling off the crankshaft sprocket.
10. After the new chain has come out of the drive chain cover, maintaining tension on both chain runs, remove the old chain from the new one.
11. Install the new chain onto the camshaft sprocket and connect it with a chain link inserted from the rear of the sprocket.
12. Install the locking plate onto the chain connecting link and rivet it. When rivet, support the chain connecting link from the back with a large hammer. Be careful not to damage the chain or the camshaft sprocket.
13. After riveting the chain connecting link, check that there are no metal burrs left on it.
14. Install the chain tensioner.
15. Turning the engine crankshaft clockwise, set the piston of the first cylinder at the top dead center and check that all the timing marks are aligned with the pointers.
16. Install the radiator fan and shroud.
17. Install the fuel injectors.
18. Connect the ground wire to the battery.
