Note these pages are copied as represented in the manual which differ from what what we know. In particular there is a mix-up in builders between the 117/118s, and 51495-51540 are shown as being built by Cravens. These could either be errors or they could be changes in the orders.

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. We also believe that all A51s originally had winch gear fitted to assist with engine swaps. Further details would be appreciated. | ||
A52
| 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. | ||
