Timing chain kits from VAICO

Function

The timing chain runs over different gear wheels and slide rails and is kept taut by tensioning elements and chain tensioners. This prevents the chain from swinging or knocking.

What types of timing chains are available?

Timing chains are available in different types of construction, e.g. as roller, pin or toothed chain in simplex or duplex version. Due to constantly decreasing installation space and the need to reduce weight, current engines are almost exclusively equipped with simplex chains, while at the same time increasing power and torque.

This development leads to the fact that the timing chain drive, which was considered maintenance-free in the past with life expectancies of more than 500,000 km for duplex chains, is increasingly becoming a wearing part and an initial change of the timing chain in some engines becomes necessary after only 50,000 km.

How do you recognize problems in the timing chain?

The problems are usually announced by rattling noises from the engine, but can then worsen until the timing is changed and the engine indicator light comes on, or even cause the chain to break, which usually results in major engine damage when pistons and valves collide. In most cases, the causes are elongation of the chain due to wear or a defective chain tensioner.

Repair of the chain drive

When repairing the chain drive, VAICO recommends replacing the timing chains installed in the engine with all tensioners, slide rails and sprockets at the same time in order to overhaul the complete system with matching new parts.
