Description
Steel center main strap for small bore engines, comes with longer high tensile bolts. Main top cap needs machining flat, no other modifications required. On all performance A series engines it is essential to ensure accurate and as near permanent location of the center main bearing of the crankshaft as possible. Flexure allowed here, especially at sustained high RPM levels, can cause spun bearings, crank or main cap breakage with severe or mortal damage to 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.
