This blog, in addition to the usual maintenance details for classic mini cars, an attempt is made to explain the "whys" and "wherefores" of the various jobs.

If the engine has covered a very high mileage, a partial overhaul may not be very effective. It will probably be necessary to reborc the cylinders

The engine and standard transmission. On later models a sixteen-blade fan is fitted and the latest type of clutch has a diaphragm spring

instead of the coil springs illustrated and fit oversize pistons, regrind the crankshaft journals to take undersize connecting-rod and main-bearing shells and renew the timing chain and sprockets and possibly also the oil pump and the starter ring gear. Un¬doubtedly the most satisfactory course in such cases will be to install a new engine under the service-exchange scheme.
