Classic Austin Mini LUBRICATION - Oil pumps
Created: January 24, 2001
Essential to the well being of every engine is its oil pump and oil. Much in the same way as the heart and blood is deemed relatively important to us humans! It’s also another of those greatly misunderstood and, unfortunately, misrepresented subjects connected to engines.
Created: January 19, 2001
This is another of those subjects that crops up on the message board frequently. I am constantly surprised by the number of engine builders - or people who charge other folk for building engines at any rate - that never hand out such an information sheet. It seems pretty daft to me that having taken a wad of money off of a customer for an engine you've lovingly put together, you'd want to help that person get the very best out of the engine.
Centre Main Cap Strap Fitting Instructions, CMS10
Created: December 05, 2000
This strap is used to give support and strengthen the centre main bearing cap on small-bore engines (850/998/1098cc). It helps counter the problems caused at higher rpm where crankshaft flex (‘whip’) causes the standard cap to move (‘shuffle’) leading to bearing failure and possible breakage of the main bearing caps. In particular, where higher rpm than standard will be the norm – i.e. in excess of 6,000rpm. Especially where this is for extended periods.

1275cc A Series Engine Color Schemes, Sprites & Midgets
Created: June 19, 2000
Only engines bearing a 12CC engine no. prefix were painted in British Motor Corporation Engine Green (the color somewhere between sage green and olive green applied to the power units in most BMC motor vehicles, including all the Sprite and Midget variants prior to 1967). This equates to roughly the first year of 1275 production.
Water pump toothed belt drive, C-AEA536
Created: January 30, 2000
This system has been designed and developed for use primarily for racing where a positive drive system is demanded to avoid fan belt loss problems caused by out of line pulleys and ill fitting belts.
Toothed belt drive for charging system C-AEA536A
Created: January 30, 2000
The large alternator/dynamo pulley is driven from the water pump pulley by a separate belt, thus ensuring the vehicle is still driveable should the charging system belt fail as the water pump will still function. Do not over tighten belt. Correct tension is when you can easily twist the belt through 90°.

Crankshaft Oil Seal Adapter
Created: January 30, 2000
Remove the flywheel, back plate, sump and the half-round cover, secured to the block by 3 bolts, above the main bearing cap (MBC). Carefully clean up the rear block face area adjacent to the MBC (Fig. 1 A); removing all traces of gasket, burrs, etc.; also the outer, horizontal edge of the flywheel mounting flange on the crank. This is where the new oil seal will seat; it will need to be checked for damage and carefully polished smooth with wire wool or fine emery.
