LUBRICATION OF ROAD SPRINGS.

Owing to the lack of lubrication to the rear end of the off side front road spring on 25-EX., we should like the shackle bolt E.81923 modified with a cross groove to Hs.{Lord Ernest Hives - Chair}465. A similar groove should be made in the rear shackle bolt F.82063.

The modified shackle bolts should be fitted to 25-EX. and the bumper chassis.
