Screw the sealing pin into the guide plate "VAS 5161/29" 2-. Screw in the adapter by hand "VAS 5161 /11" into the thread for the corresponding glow plug.
Insert the VAS 5161/ZA punch into the guide plate and tap it with a plastic hammer to loosen the valve crackers.
Screw the bracket into the guide plate "VAS 5161/6" with a fork "VAS 5161/5". Insert the mounting chuck into the guide plate "VAS 5161/8" with the "VAS 5161 A/31" bushing installed on it 1-. Connect the adapter via a standard adapter to a compressed air source and apply constant pressure. Minimum pressure: 0.6 MPa (6 bar) excess pressure. Hook the pressure lever "VAS 5161/2" by the adjustable stop and press the mounting cartridge down.
At the same time, turn the rod installed in the mounting chuck clockwise until the fork located on its end enters the gaps between the crackers. Alternately turn the rod first one way, then the other - the crackers will be pressed away from each other and fixed in the chuck. Release the pressure lever. Remove the mounting chuck with the sleeve. Remove the valve spring with the plate. Using the puller "3364" remove the oil scraper cap.
Caution! Risk of damage when installing valve stem seals. Place the plastic sleeve "A" supplied with the new valve stem seal "B" onto the valve stem.
Lightly lubricate the working edge of the valve stem seal with oil. Place the valve stem seal on the plastic sleeve. Carefully press the valve stem seal onto the valve guide sleeve using the "3365" mandrel. Remove the plastic sleeve.
If the valve crackers have been removed from the mounting cartridge, they must first be inserted into the fixture "VAS 5161/18". The larger diameter of the valve crackers should be directed upwards. Insert the valve spring with the plate. Press the mounting cartridge from above onto the mounting device and grab the valve crackers.
Reinsert the mounting cartridge into the guide plate "VAS 5161 A/31". Press the lever and, turning the rod of the mounting cartridge first one way, then the other, insert the crackers into place. Release the pressure lever with the rod still pulled out. Repeat the operation on each valve.
Installation
Installation is in reverse order. Check that all roller valve levers are correctly seated on the ends of the rods and hydraulic compensators. Install the camshaft housing. Install the glow plugs.
