-- 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 shown.
-- Connect the cylinder head tensioning device to 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.
-- Fasten the : VAS5161/19C on the cylinder head as shown using the : VAS5161/12 .
-- Insert the : VAS5161/3 in the guide plate and loosen the stuck valve retainers with a plastic mallet.
For the Intake Side
-- Install the : VAS5161/6 with the : VAS5161/5 in the center threads on the : VAS5161/19C .

-- Engage the : VAS5161/2 on the : VAS5161/6 .
For the Exhaust Side
-- Install the : VAS5161/6 with the : VAS5161/5 in the outer threads on the : VAS5161/19C .
-- Press down the : VAS5161/8A and at the same time turn the knurled thumb screw on the : VAS5161/8A to the right until the points engage in the valve retainers.
-- Move the knurled thumb screw back and forth slightly. This presses the valve retainers apart and captures them in the installation cartridge.
