3.1.12. Maslootrazhatelny caps
GENERAL INFORMATION

Worn-out maslootrazhatelny caps can cause the raised oil consumption. Caps can be removed also at the established head of the block of cylinders. However, at the same time compressed air and a lever pusher with the basic device, for example, of Mercedes-11 589 015900, 11 589 186 186 100 and 11 589 256 300 is necessary. If there is no special tool, then it is necessary to remove a head of the block of cylinders.

Below replacement of maslootrazhatelny caps for the 4-cylinder engine is described, and for 6-cylinder – act on sense, using the corresponding tool.

Removal

Prevention

If details of control of the valve are used again, they should be mounted on the same places. Not to mix a detail, manufacture the special panel for their storage.

PERFORMANCE ORDER
1. Remove camshafts.
2. Remove spark plugs.
3. Remove a sheeting of wires of the engine on a forward wall of a body.
4. Fasten a basic crossing point (2) with a mobile detail (7) to bearings 1 and 5 of the camshaft or 20 N. are later to bearings 6 and 10 with the moment than m.
5. Turn in VMT the piston of the corresponding cylinder a wrench with a nozzle. 4-cylinder engine: at the provision of VMT of a belt pulley pistons 1 and 4 stand in VMT. At coincidence of a 180-degree mark of a belt pulley to a basic mark in VMT there are pistons of cylinders 1 and 6. 6-cylinder engine: at the provision of VMT of a belt pulley in VMT there are also pistons of cylinders 1 and 6. At coincidence of a 120-degree mark of a belt pulley – pistons of cylinders 2 and 5; at a 240-degree mark – pistons of cylinders 3 and 4.
Prevention

At turn of a bent shaft highly raise the operating chain that it was not jammed.
6. Hang a lever pusher.
7. Extend a dish-shaped pusher (3) a rubber sucker (diameter of 30 mm), for example, of HAZET 735-2.
Prevention

Do not use for this purpose a magnetic siphon as the surface of sliding of a dish-shaped pusher is magnetized, and subsequently on it the smallest metal shaving is laid that leads to damage of a pusher and cams.
8. Record a bent shaft. For this purpose establish the first transfer and tighten the parking brake.
9. Install excessive pressure at least 6 bars in the cylinder combustion chamber. For this purpose screw in a subconnecting hose (4) devices for check of tightness of the cylinder in a spark plug opening. If there is no control device of tightness, it is possible to make the corresponding hose by me
