AEC ENGINE VARIATIONS
The AEC Spare Parts catalogue divides engines into two sections: A51 or A52. Second column below is the DTO nos. and should be referenced to the tables above.
A51
| A220L | 1/B, 1/2, 1/5 | Engine complete with flywheel (belt tensioner & dynamo) |
| A220S | 1/3, 1/20 | Engine complete with flywheel (right-angle drive) |
| A220W | 1/6 | Engine as A220S with two oil-pressure switches |
| A220Y | 1/7, 1/11, 1/11B | Engine as A220L less dynamo |
| These all had 18" flywheels and were supplied without fuel filter, fuel pipes and electrical installations. I also believe that all A51s originally had winch gear fitted to assist with engine swaps. Further details would be appreciated. | ||
A51
| A220AC | 1/12, 1/14 (24-off), 1/16, 1/17,1/21, 1/22, 1/23 (6-off), 1/25, 1/27, 1/31, 1/33, 1/40, 1/57 | Engine complete with flywheel, twin fuel filter, fuel pipes & fittings and electrical installations (right-angle drive) |
| A220AJ | 1/26 | Engine as A220AC less air compressor and one oil-pressure switch |
| A220AK | 1/51, 1/56 | Engine as A220AC with 3" shorter oil filler tube |
| A220AL | 1/34 | Engine as A220AK with Simms starter motor |
| A220AZ | 1/32 | Engine as A220AJ less fan shaft spacer and with different electrical installations |
| A220BB | 1/55 | Engine as A220AC with Simms starter motor |
| These all had 20" flywheels and were supplied with fuel filter, fuel pipes and electrical installations. | ||
