Rolls-Royce 20/25 - dismantle sub frame





The grubby engine sub frame - viewed from the front and above.

rear view


A view from behind and underneath.  Note the two rear flanges that ensure accurate location to the rear block bridge pieces.

frame parts


The parts, minus the lower half-cylinder clamp for the centre.  The bronze bush is an interference fit into the lateral beam.  The steel journal is clamped into the centre bracket by the two 3/16" BSF studs.

The centre hole on the beam has an annular groove machined inside to allow oil to bleed behind the bronze bush and lubricate the steel journal.  Needless to say, the whole system was completely blocked with rust, grease and dirt.
