5.6. Removal, installation and дефектовка a flywheel

Flywheel remove for replacement of a back epiploon of a cranked shaft, for replacement at damage of a gear rim and for surface grinding under a conducted disk of coupling.

It be required to you: the tools necessary for removal of a transmission and coupling, and also a face head on 17 and the big screw-driver.

1. Remove a transmission (Removal and transmission installation see) and coupling (Removal and coupling installation see).

2. Mark in any way a relative positioning of a flywheel and a cranked shaft.

THE NOTE The flywheel can be established on a cranked shaft only in one position as one of apertures in a flywheel and cranked to a shaft is located asymmetrically (has angular displacement), however for simplification of installation of a flywheel is recommended to mark a relative positioning of details.

3. Turn out five bolts of fastening of a flywheel. Thus by means of a screw-driver keep a flywheel from проворачивания, having screwed preliminary one of bolts of fastening of a transmission.	4. Turn out the sixth bolt and remove a flywheel.

5. Check up a condition of teeths of a rim of a flywheel and in case of their damage replace a flywheel.

6. Replace or repair a flywheel if on surfaces прилегания a conducted disk of coupling or a flange of a cranked shaft there are risks and teases.

7. To check up and repair a flywheel it is possible in a workshop having the special equipment. The palpation of a flywheel measured on a gear wreath, should not exceed 0,5 mm. For removal deep рисок and задиров a surface прилегания a conducted disk it is possible прошлифовать, thus the layer of removed metal should not exceed 0,3 mm.

8. Establish a flywheel and all removed knots in sequence, return to removal. A carving of bolts of fastening of a flywheel grease анаэробным with a carving clamp, preliminary having degreased bolts and carving apertures under them. Tighten bolts in regular intervals cross-wise the moment 35 Нм (3,5 кгсм) and in addition tighten on a corner 30–45 .

GOOD ADVICE Whenever possible at each removal of a flywheel replace bolts of its fastening new.
