 PERFORMANCE ORDER

  1. Remove the power unit from the car.
  2. Install the piston of the first cylinder in the provision of VMT of the end of a step of compression and uncover the GRM drive (see the Section Removal and installation of a cover of the GRM drive).
  3. Remove the top guide and a natyazhitel of a chain of the drive of balancing shaft (5 on an illustration Components of installation of a chain of the drive of balancing shaft).
  4. Remove a mobile guide.
  5. Remove an intermediate asterisk and a chain (7 on an illustration on an illustration Components of installation of a chain of the drive of balancing shaft).
  6. Make sure that asterisks and guides are in the normal state. Do not forget to check the fixed guide (8 for illustrations Components of installation of a chain of the drive of balancing shaft) which is the general for a chain of the GRM drive and a chain of the drive of balancing shaft. If necessary replace worn-out components.
  7. Pay attention that asterisks of balancing shaft differ from each other. Remove asterisks (9 on an illustration Components of installation of a chain of the drive of balancing shaft).
  8. Check that the plunger of a natyazhitel of a chain is located correctly – if it can be squeezed out completely, turn it on the 180th hail.
  9. Turn a plunger of a natyazhitel of a chain on the 90th hail., press it, and turn in a starting position. Record a natyazhitel in this situation, having inserted, for example, a paper clip into the opening located in the top part of its case.
  10. Establish a natyazhitel from a mobile guide.
  11. Establish the fixed guide (4 on the illustration Installation of a Chain).
  12. Level tags on balancing shaft with tags on the corresponding cases of bearings (5 on the illustration Installation of a Chain).
  13. Lay a chain on an asterisk and stretch it through an intermediate asterisk.
  14. Check the provision of balancing shaft and release a natyazhitel. Make sure that the plunger of a natyazhitel has the small course.
  15. Further installation is made as it should be, the return to an order of dismantle of components.
