Reworking the :VAS5161/19C :
In place of the :VAS5161/19C , the :VAS5161/19B may also be used. To do this, the following reworking must be completed as follows:
-- Lengthen the long opening to 2 mm as shown in the illustration.
To use this, the guide plate is only attached to the cylinder head with a knurled bolt.
-- Remove the intake manifold. Refer to INTAKE MANIFOLD, REMOVING AND INSTALLING .
-- Mark the allocation of the roller rocker lever and the hydraulic adjusting elements so they can be installed again.
-- Remove the roller rocker lever with the hydraulic lifter and place them on a clean surface.
-- Insert the :VAS6419 in the :VAS6095A .
-- Tension the cylinder head on the cylinder head tensioning device, as illustrated.
-- Connect the cylinder head tensioning device to the compressed air.
-- Slide the air cushion with the lever -arrow- under the combustion chamber onto the valve stem seal that will be removed.
-- Let enough compressed air flow into the air cushion until it contacts the valve plate.
-- Position the : VAS5161/3 on the valve spring plate and loosen the stuck valve retainers with a plastic mallet.
-- Place the : VAS5161/19C on the cylinder head.
-- Secure the guide plate with the :VAS5161/12 .
-- Install the :VAS5161/6 with the :VAS5161/5 in the guide plate.
-- Push installation cartridge :VAS5161/8 into guide plate.
-- Engage the : VAS5161/2 at the engaging device and press the installation cartridge downward.
-- At the same time, rotate the cartridge knurled screw right until points engage in valve retainers.
-- Move the knurled thumb screw back and forth slightly. This presses the valve retainers apart and captures them in the installation cartridge.
-- Release the pressure fork.
-- Remove the cartridge.
-- Unfasten guide plate and turn it aside.
-- Remove the valve spring and the valve spring plate.
-- Remove the valve stem seal with the :3364 .
In order not to damage the valve stem seal -4- during installation, mount the Mounting Sleeve -3- on the valve stem -2-.
-- Lightly oil the valve stem seal.
-- Insert the valve stem seal in the :3365 and carefully press on over the Mounting Sleeve on the valve guide -1- all the way.
-- Remove the Mounting Sleeve.
If the valve retainers were removed from the installation cartridge, they must then be inserted into the :VAS5161/18 .
- The large diameter of the valve retainers point upward.
-- Press the cartridge from above onto the insertion device and capture retainers.
-- Insert the valve spring and the valve spring plate, for allocation. Refer to 32.
-- Attach the :VAS5161/19C onto the cylinder head again.
-- Insert installation cartridge in guide plate.
-- Press the pressure fork down and pull the knurled screw up while turn left and right. This inserts the valve retainers.
-- Release the pressure fork with the knurled screw still raised.
-- Repeat the procedure on each valve.
