LUBRICATION OF REAR SPRINGS.
Owing to the lack of lubrication to the rear end of the rear springs of 25-EX we consider the capacity of the swivel pin F.82108 should be filled with a piece of wood, provision being made for a duck for the oil.
A similar arrangement is used on the brake actuating shafts.
