Injection Equipment Information
CAV Date Coding Letters

®

Original Table by Andy Selfe, South Africa
The original method of marking equipment by stamping a two-letter code was revised in 1959, and the lettering restarted at NA.
Note that in early 1967, a small batch of equipment was stamped with the letter 'I' in the date code,
which does not appear at all in the 1959 to 1982 batch otherwise, neither does the letter 'Q'.
Letter pairs highlighted in RED are those which have checked out at least in years if not in months to an engine manufacturing date.
