Used in combination with Valve Sping Compressor V5034. Can be clamped in a vice. This tool stops the valves from moving while pressing the valve spring down. Made from beech.

The cylinder heads of the different models have different depths of the compression room, which is why the valve -blocking plate is supplied with a plastic block with an M10 threaded rod: this allows different heights to be set.

The M10 threaded bushes are placed in such a pattern that the cylinder heads of all 1 cylinder and 2 cylinder models can be tightened with 2 crosswise placed cylinder head bolts
