Installing Conditions
Note: |
Gradual introduction of PTFE oil seals (Poly-Tetra-Fluor-Ethylen). Identifying characteristics: no annular spring, sealing lip wider. The sealing lip of this oil ring must not be oiled or lubricated. A plain encased seal of older construction (with annular spring) may be replaced with a PTFE oil seal, but not vice versa.
|
Note: When the camshaft is turned, the crankshaft must not be at TDC. Danger of damage to valves or piston crowns. The rest of the assembly is basically a reverse of the dismantling sequence. Installing toothed belt and adjusting valve timing . |
