Dealer Letter #116

SUBJECT: 18 H.P. ENGINES PRODUCED WITH .020 OVERSIZE CYLINDER BORES WITHOUT BEING IDENTIFIED

Gentlemen:

You will recall in June of 1963 (SB-#957) you were informed of new motors being produced with .020 oversize cylinder bores and would be identified with the stamping of "OS" immediately below the serial number on the cylinder numbering plug.

Erroneously several 18 H.P. engines were produced and shipped without the "OS" stamp but do contain .020 oversize cylinder and pistons. They are as follows:

FD-18E #2452152 to and including #2452625

FDL-18E #2454090 to and including #2454189

Please make a special note of these engines and their respective serial numbers and in the event you have any of them in stock, sold and delivered or if you receive them later, you can properly identify your records accordingly when attempting to service them at any time in the future.

Your special attention and cooperation please.
