4.4.5. Check, removal, installation and adjustment of a gear belt


Surely replace the damaged gear belt.

Besides a camshaft pulley the gear belt rotates also pulleys of water and fuel pumps.


See subsection


1. Remove casings of a gear belt and a pulley of a bent shaft.
2. Remove a weight wire from the accumulator.
3. In the lower part of a case of the transmission uncover a flywheel and coupling.
4. To install the piston No. 1 in VMT, turn a bent shaft clockwise and combine an adjusting tag on a pulley of the fuel pump with the corresponding index on a pump arm.
5. Check that the adjusting tag (A) of a flywheel was combined with the index (V) on a coupling case.
6. Remove the vacuum pump and block the camshaft by means of the special tool (KM-537). If you do not have this tool or it cannot be established, make marks in a pulley of the camshaft and a back casing of a gear belt.
7. Weaken bolts of fastening of the water pump (are specified by shooters) and turn the pump to weaken a tension of a gas-distributing belt.
8. Remove a forward support of the engine.
9. Make the tag specifying the direction of its rotation on a belt.
10. Take off a gear belt.


1. Put on a belt pulleys. Check that the piston of the first cylinder was in VMT, and adjusting tags of pulleys of the fuel pump and a flywheel were combined with the corresponding indexes.
2. Turn the water pump to pull a gear belt, and tighten bolts of fastening of the pump.
3. Remove the tool for blocking of the camshaft and establish a pulley of a bent shaft.
