ACL BMC Mini Inline 4 (997cc, 998cc) .001mm Oversized High Performance Rod Bearing Set

When you're rebuilding or refreshing the engine in your 1962 Austin Mini Cooper, especially if you're pushing a bit more power, the rod bearings are a critical component. This set from ACL is designed for the Inline 4 engines found in the 997cc and 998cc models, and they're .001mm oversized to ensure a perfect fit on crankshafts that have been machined to that specification. These aren't just standard replacement bearings; they're built for high performance, meaning they can handle the extra stress that comes with a tuned engine.

ACL uses a specialized overlay material in these bearings, which is known for its strength and ability to resist fatigue under high loads. This is important because the connecting rod bearings are constantly working under immense pressure and friction as the crankshaft spins. The .001mm oversize is a precise measurement, indicating these are intended for engines where the crankshaft journals have been reconditioned to that exact size. This ensures proper oil clearance, which is vital for both lubrication and bearing longevity, especially in a performance application.

If you've already had your crankshaft measured and machined to a .001mm undersize, this ACL bearing set is the correct choice to get your Mini's engine back together with reliable components. Proper installation, including ensuring the crankshaft journals are clean and within tolerance, is key to getting the most out of these high-performance bearings.
