Technical characteristics of the valve timing mechanism (Opel Kadett E)

The engine uses a valve timing mechanism with a side-mounted camshaft, driven by a single-row roller chain. The chain tension is adjusted automatically by a tensioner.

Valve timing*

*With working clearances in the valve drive mechanism of 0.15 mm for intake valves and 0.25 mm for exhaust valves

Camshaft

The camshaft is three-bearing, side-mounted, with a chain drive. The shaft rotates in bearing bushings pressed into the cylinder block bores, the holes of which must be reamed to the dimensions specified in the table. The camshaft is held from axial movement by a steel locking plate inserted into the groove of the front support.

Axial clearance of the camshaft, mm: 0.17-0.43.

Radial runout of the middle journal of the camshaft relative to the outer journals, measured at the centers, mm: 0.03.

Lift of intake and exhaust cams, mm: 6.45.

Camshaft drive chain

The chain is single-row, roller, has 56 links with a pitch of 9.525 mm.

Chain width, mm: 13.
