To provide a better oil seal, the depth of the counterbore in the A-3548 steering gear housing has been changed from 3/64 inch to 5/64 inch.
To compensate for the increased depth of the counterbored hole the thickness of the steering gear cover gasket A-22448 has been changed from 3/32 inch to 1⁄8 inch.
The outside diameter of the gasket has also been changed from 2 19/64 inches to 2 11/32 inches and the inside diameter from 1 23/32 inches to 2 1/16 inches. (See Fig. 954.) The new gaskets can be used in old steering gear housings.
