3.11.7. Directing plugs of valves

1. Check up a backlash between directing plugs and a valve core, having measured diameter of the valve and an aperture of the directing plug. An assembly backlash for new plugs: 0,022–0,055 mm – for inlet valves and 0,029–0,062 mm – for final valves; as much as possible admissible limiting backlash (at deterioration)
0,15 mm.
2. If the increased backlash between the directing plug and the valve cannot be eliminated valve replacement, replace plugs of valves, using оправкой А.60153/R (1 – оправка А.60153/R).
3. For replacement of two directing plugs of inlet and final valves of cylinders № 1 and № 4 turn on two hairpins of fastening of the case of bearings of a camshaft as they disturb to installation оправки.
4. Запрессовывайте directing plugs with the put on lock ring against the stop rings in a plane of a head of cylinders.
5. After запрессовки develop apertures in directing plugs development А.90310/1 (for plugs of inlet valves) and А.90310/2 (for plugs of final valves). Then прошлифуйте a saddle of the valve also finish width of a working facet till the necessary sizes as it is specified above.
