ML40+ and ML+40 Adaptor Plate

When fitting an ML40+/ML+40 in place of an earlier ML40S non-adjustable type either the mountings will have to be remade or an adaptor plate used.

The R4065 adaptor plate enables the existing mounting to be used by placing the ML40Plus further back. This maintains the relative rod-end position.

The plate is either available from ourselves or an engineering drawing can be obtained from the link below for those wishing to fabricate themselves.
