Instruction. Make sure that already working camshaft bearing shells are not mixed up in places (take note of the label).
Make sure that the pushers are not mixed up, to do this, mark on the back side with a waterproof felt-tip pen.
Remove pushers from guides. Fold the pushers in the order they were removed on a clean bedding with the working surface down. Insert pin -VAS 5161/3- into pusher guide. Knock out with a plastic hammer firmly seated crackers of all valves. Unplug electrical connectors -2- for glow plugs. Other -pos.- are ignored.
Unscrew all glow plugs with SW 10 joint wrench -3220-. Set the piston of the corresponding cylinder to "bottom dead center".
Screw adapter -VAS 5161/11- into the corresponding glow plug socket by hand. Screw in universal hitch -VAS 5161/6- with a fork (MB) -VAS 5161/5- into the threaded hole in the cylinder head. Insert guide sleeve -VAS 5161/16- into tappet guide of removed valve as far as stop. Mounting position of the guide sleeve: The serrated surfaces are transverse to the direction of travel. Insert assembly cartridge -VAS 5161/15- into guide bush. Connect adapter -VAS 5161/11- to compressed air hose using standard intermediate piece.
Minimum pressure: 6 bar overpressure. Position fork -VAS 5161/2- on universal hitch -VAS 5161/6- and push assembly cartridge downwards. At the same time, turn the knurled screw of the mounting cartridge to the right until the ends fit into the valve cotters. Slightly turn the knurled bolt back and forth, due to this, the valve pins are unclenched and captured by the cartridge. Release the pressure fork. Remove mounting cartridge. Remove the guide bushing, valve spring plate and valve springs. Press out pin -arrow- of puller -3047 A- with a beard and remove striker.
Attach bottom part of extractor -3047 A- to oil seal. Secure puller -3047 A- with a punch or cotter pin tool as shown in the illustration. Position assembly lever on puller -3047 A- and remove oil seal arrow-.
The set of new valve stem seals includes a plastic sleeve -A-. Push the plastic sleeve -A- onto the valve stem to prevent damage to the new valve stem seal -B-. Lightly oil the sealing lip of the valve stem seal. Push the oil seal onto the plastic bushing. Carefully press valve stem seal with valve stem seal tool -3129- onto valve guide. Remove plastic bushing.
If the valve cotters have been removed from the assembly cartridge, they must first be inserted into the assembly tool -VAS 5161/18-. The larger diameter of the valve pin points upwards.
Insert valve springs, valve spring plate and guide sleeve -VAS 5161/16-. Press assembly cartridge -VAS 5161/15- onto assembly tool from above and engage valve cotters. Insert assembly cartridge -VAS 5161/15- into guide sleeve -VAS 5161 /16-. Push down on the pressure fork and pull up the knurled bolt while turning it to the right and left, the valve cotters will be inserted. Unload the pressure fork while the knurled screw is still pulled out. Install pushers. Install distributor. Install glow plugs.
Instruction. After installing the camshaft, the engine must not be started for about 10 minutes. Hydraulic tappets must be deposited (otherwise the valves will come into contact with the pistons). After working on the valve train, rotate the engine by hand at least 2 revolutions to make sure that no valve is in contact with the piston.
