Prevention

At removal of a chain it is necessary to use a nazhdachny circle or вулканит, for cutting of coming-out hats of one of chain links.


Soshlifovyvaniye of rivets of one of links of a chain (And) and link removal from a driving chain (In)

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Unscrew spark plugs.
3. Unscrew the mechanism of a tension of a driving chain.
4. Remove the top cover of a driving chain.
5. Remove the top uspokoitel of a chain.
6. Uncover heads of the block of cylinders.
7. Close pure rags a head of the block of cylinders and space under an asterisk ми camshafts.
8. Using a nazhdachny circle or вулканит, сошлифуйте rivets of one of chain links from an asterisk of the camshaft operating final valves (see drawing).
9. Remove fixing plate and a chain link from a driving chain.
10. Being careful, remove rags so that metal shaving did not get to a cover of a driving chain.
11. Using a connecting link of a chain, connect the ends of an old and new chain.

13. After emergence of the end of a new chain disconnect an old chain from the new.
14. Establish a new chain on an asterisk of the camshaft operating final valves, then connect two ends of a chain.
15. Establish fixing plate and расклепайте a connecting link of a chain.
16. Establish the top uspokoitel of a chain.
17. Establish the top cover of a driving chain.
