Valve guides, intake and exhaust set - Fulvia 2nd series

Valve guides, bronze alloy, complete set for intake and exhaust, suitable for Fulvia 2nd series.

Background:
When replacing the valves, the valve guides should also be checked. Damage to valves can often come from old, worn valve guides. In the case of the Fulvia valves, which are operated by rocker arms, knocked-out valve guides lead to increased radial force transmission on the valve stem. As a result, the valves in the puncture area for the valve wedges can break. If valve replacement is necessary, the clearance between the valve stem and the inner diameter of the guide must not exceed the stated values. If the play is too great or if the valve guide is worn out of round, conical or trumpet-shaped, you must replace it. Source: Kolbenschmidt

Valve guide clearance:
Valve stem diameter / intake valves / exhaust valves
5 … 7 mm / 10 … 40 μm / 25 … 55 μm
7 … 9 mm / 20 … 50 μm / 35 … 65 μm
9 … 12 mm / 40 … 70 μm / 55 … 85 μm
