WHERE TO LOOK FOR CHASSIS & ENGINE NUMBERS
on Vintage Bentley cars
 
 
Model Chassis Number Engine Number
3

4½ S/C
Near side of chassis front cross member and gear box front cross member Starter motor housing and magneto cross shaft housing
Near side of chassis front cross member Near side engine bearer arm
8 Ledge on near side of bulkhead Front engine foot just in front of the cylinder block
4 Ledge on near side of bulkhead Nearside top of timing case
 
 

NOTES

The chassis markings have usually been painted over and with the exception of the 4 and 8 Litres will need scraping.

The chassis number is not always stamped on the gear box front cross member in the 3 and 4 1/2 Litres, nor the engine number always on the magneto cross shaft housing.

The chassis number can also sometimes be found on the front axle beam and on the top of the rear axle nose piece but as these parts are easily changeable they are not conclusive.

"S" after the engine number indicates a Service replacement engine.

"SS" after an engine number indicates the Super Sports engine as fitted to the 9' chassis. In 1926 the specification of this engine became the Standard Speed Model engine.
