Morris Mini-Minor engine
The engine bay of the first production Morris Mini-Minor 621 AOK, and a familiar sight to all Mini owners during the 41 year production run of the Mini, because it hardly changed! Taking up most of the space is the 848cc four-cylinder overhead-valve push-rod A-Series petrol engine producing a mere 34bhp (37bhp gross) at 5,500 rpm maximum torque 44lb.ft at 2,900rpm. The four-speed gearbox with synchromesh on 2nd, 3rd and fourth gears and final drive is mounted under the engine in the sump. The A-Series engine with various power outputs powered all Minis from 1959-2000. The A-Series engine was launched in 1951 by the Austin Motor Company with the Austin A30.
Lets have a look around the engine at other items, the coil and distributor are mounted in front of the engine, just in front of the coil is the front offside headlight allowing easy access to replace bulbs, unlike today's modern cars! To the right of these items is the dynamo. On the right-hand side of the engine is the pressurised radiator, out of view next to the radiator is the windscreen wiper motor, also out of view near the right wing (front nearside) is the car build plate with all the information about the car including the paint code, no VIN plate 60 years ago.
Mounted on the rear of the engine is air filter in the black canister with a wing nut to allow the top to be removed. To the right on the bulkhead is the chassis number BKK 101. Underneath the air filter is the S.U. carburettor (S.U. was a subsidiary of BMC) on top of the carburettor is the piston damper, which screws off to allow the reservoir to be topped up with oil, which would be done periodically. The function of the damper was to provide an appropriate degree of enrichment for acceleration. To the left of these we can see the two hydraulic reservoirs for the braking system and clutch. To the left of the engine is the fuse and relay box, in front of this is the windscreen washer bottle. Just in case you are wondering where the battery is, that item is in the boot. In all everything is easy to get to, unlike today's modern cars!
