ENGINE LUBRICATION
re experiment on oiling cylinders
(a) Found No. 5 Cylinder oiled up
(b) Moved piston from No.5 to No. 6 Cylinder (oil up to No. 6 Cylinder)
(c) Replaced No. 5 piston in 5 cylinder with 6 holes Then oiled up No. 5 cylinder
(d) Changed No.2 piston (which was dry) for No.5 piston and this oiled up No. 2 cylinder
In making changes I always moved the rings with the piston and always left the gudgeon pins alone. Herewith are sizes of cylinders and pistons (See over) following card
