Type III Engine and Chassis numbers Like early VW chassis, early Type III engines were just numbered sequencially. The actual engine variety had to be identified visually or by a tag that specified the M-number to which it conformed. Starting with the 1966 model year VW introduced a numbering scheme which identified the engine type by incorporating a letter at the start of the engine serial number. Comments to Jim Adney, jadney@vwtype3.org These later numbers may be used to identify the exact nature of the engine that your crankcase was originally built into. The various engines available on the Type III chassis were: xxxxxx (straight numbered) 1500cc, single or dual carbs, regular or low compression K 0xxxxxx 1500cc, single 32 PHN Solex carb, regular compression M 000xxxx 1500cc, single 32 PHN Solex carb, low compression (M240) T 0xxxxxx 1600cc, dual 32 PDSIT Solex carbs, regular compression P 000xxxx 1600cc, dual 32 PDSIT Solex carbs, low compression (M240) U 0xxxxxx 1600cc, Bosch D-Jetronix fuel injection (M236) U 50xxxxx 1600cc, Bosch D-Jetronix fuel injection (M236/M239) X 000xxxx 1600cc, Bosch D-Jetronix fuel injection (M236/M27) VW Type III Engine Production Survey Model Year 1961/62 4/1/61 12/31/61 7/31/62 Engine number: 1500 33KW 45BHP 000001 013012 065745 1500 30KW 41BHP (M240) 000001 013012 065745 Chassis number: 000001 011041 064739 Model Year 1963 8/1/62 12/31/62 7/31/63 Engine number: 1500 33KW 45BHP 065746 143557 255339 1500 30KW 41BHP (M240) 065746 143557 255339 Chassis number: 066740 138774 221974 Model Year 1964 8/1/63 12/31/63 7/31/64 Engine number: 1500 33KW 45BHP 255340 406183 633330 1500 30KW 41BHP (M240) 255340 406183 633330 1500 40KW 54BHP 255340 406183 633330 1500 38KW 52CV (M240) 255340 406183 633330 Chassis number: 221975 321076 483592 Model Year 1965 8/1/64 12/31/64 7/31/65 Engine number: 1500 33KW 45BHP 633331 816281 1100000 1500 30KW 41BHP (M240) 633331 816281 1100000 1500 40KW 54BHP 633331 816281 1100000 1500 38KW 52BHP (M240) 633331 816281 1100000 Chassis number: 315 000 001 315 105 296 315 220 883 Model Year 1966 8/1/65 12/31/65 7/31/66 Engine number: 1500 33KW 45BHP K 0000001 K 0020000 K 0060000 1500 30KW 41BHP (M240) M 0000001 1600 40KW 54BHP T 0000001 T 0126399 T 0260000 1600 36KW 50BHP (M240) P 0000001 Chassis number: 316 000 001 316 140 226 316 500 000 Model Year 1967 8/1/66 12/31/66 7/31/67 Engine number: 1500 33KW 45BHP K 0060001 K 0076495 K 0098700 1600 40KW 54BHP T 0260001 T 0380413 T 0476124 Chassis number: 317 000 001 317 134 254 317 500 000 Model Year 1968 8/1/67 12/31/67 7/31/68 Engine number: 1500 33KW 45BHP K 0098701 K 0105421 K 0120744 1500 30KW 41BHP (M240) M 0001257 M 0002444 1600 40KW 54BHP T 0476125 T 0517550 T 0574185 1600 36KW 50BHP (M240) P 0002900 P 0004320 1600 40KW 54BHP (M236) U 0000001 U 0063005 U 0093651 Chassis number: 318 000 001 318 103 144 318 500 000 Model Year 1969 8/1/68 12/31/68 7/31/69 Engine number: 1500 33KW 45BHP K 0120745 K 0131969 K 0150000 1500 30KW 41BHP (M240) M 0002445 M 0002879 M 0003544 1600 40KW 54BHP T 0574186 T 0616933 T 0690000 1600 36KW 50BHP (M240) P 0004321 P 0004677 P 0005281 1600 40KW 54BHP (M236) U 0093652 U 0154029 U 0231100 Chassis number: 319 000 001 319 108 899 319 500 000 Model Year 1970 8/1/69 12/31/69 7/31/70 Engine number: 1500 33KW 45BHP K 0150001 K 0157478 K 0173002 1500 30KW 41BHP (M240) M 0003545 M 0003808 M 0004016 1600 40KW 54BHP T 0690001 T 0728613 T 0805013 1600 36KW 50BHP (M240) P 0005282 P 0005913 P 0006080 1600 40KW 54BHP (M236) U 0231101 U 0268080 U 0366020 Chassis number: 310 2000 001 310 2111 451 310 2500 000 Model Year 1971 8/1/70 12/31/70 7/31/71 Engine number: 1500 33KW 45BHP K 0173003 K 0180600 K 0198000 1500 30KW 41BHP (M240) M 0004017 M 0004163 M 0004266 1600 40KW 54BHP T 0805014 T 0854350 T 0933000 1600 36KW 50BHP (M240) P 0006081 P 0006336 P 0006900 1600 40KW 54BHP (M236) U 0366021 U 0412693 U 0502000 Chassis number: 311 2000 001 311 2108 452 311 2500 000 Model Year 1972 8/1/71 12/31/71 1/31/72 3/31/72 8/31/72 Engine number: 1500 33KW 45BHP K 0198001 K 0200870 K 0210510 1500 30KW 41BHP (M240) M 0004267 M 0004378 M 0004424 1600 40KW 54BHP T 0933001 T 0974878 T 1029686 1600 36KW 50BHP (M240) P 0006901 P 0006992 P 0007200 1600 40KW 54BHP (M236) U 0502001 U 0504538 U 0507000 1600 40KW 54BHP (M236/M239) U 5000001 U 5018596 U 5031718 U 5057000 1600 40KW 54BHP (M236/M27) X 0000001 X 0001624 X 0002340 X 0004000 Chassis number: 312 2000 001 312 2066 941 312 2078 248 312 2115 424 312 2500 000 Model Year 1973 8/1/72 12/31/72 7/31/73 Engine number: 1500 33KW 45BHP K 0210511 K 0213993 K 0221000 1500 30KW 41BHP (M240) M 0004267 M 0004449 M 0005000 1600 40KW 54BHP T 1029687 T 1056763 T 1083000 1600 36KW 50BHP (M240) P 0007201 P 0007242 P 0008800 1600 40KW 54BHP (M236) U 0507001 U 0510144 U 0512000 1600 40KW 54BHP (M236/M239) U 5057001 U 5069142 U 5090000 Chassis number: 313 2000 001 313 2058 437 313 2500 000 Compiled from VW production survey data by Jim Adney.
