rod tube of anodised aluminium with spring to obtain the correct tension. They
are 2-piece and are supplied with all necessary rubbers. Enables assembly
without dismantling the cylinder head and are sold in sets of 8.
pushrod tubes are longer on one side and this side is mounted in the crankcase.
This improvement comes from the racing and rally world and ensures that during
sporting turns no oil can run into the pipes and a temporary oil shortage can
occur at the suction opening, resulting in engine damage. Can also be used on
standard engines for normal use, so that you are always sure of a constant oil
available in metal (BBT 1758), stainless steel (BBT 1758-5) and separable for
assembly without removing the cylinder heads (BBT 1761).
