Assembling cylinder head

Note: Reusable inner parts of the cylinder head must always be cleaned thoroughly and assigned to their original installation location.





Note: Replace valve-stem seal.

1. Insert lower valve-spring plate, oil valve stem lightly and position assembly sleeve (shim set for valve-stem seals). Either set new valve-stem seal on the assembly sleeve or insert in the assembly driver 9606.








2. Press valve-stem seal with the assembly driver 9606 up to the stop on the valve stem. Take off tool and assembly sleeve.
3. Insert corresponding valve spring(s) and upper valve-spring plate.





4. Fasten assembly head to lever arm. Push sliding sleeve downward to the stop and insert the valve keys. In order to ensure correct assembly, the wedges should be centered. Then push the sliding sleeve back again (valve keys fixed).





5. Position assembly head with the pressure piece over the valve stem and align the assembly head so that it is aligned with the valve. Slowly press the assembly head downwards and guide it with your hand until a clicking sound can be heard. The valve keys are then automatically pressed into the correct installation position.
6. Swivel out the lever with the assembly head and check the seat of the valve keys. Repeat the process if necessary.
