What is the difference between H Series and other ACL bearing series?

The H Series bearings from ACL feature a tri-metal overlay, which is known for its strength and ability to handle higher loads compared to standard bearings. This makes them a popular choice for performance engine builds.

Can I use these standard size bearings if my crankshaft is worn?

Standard size bearings are designed for crankshafts that are still within factory specifications. If your crankshaft has been worn or machined, you will need to use an undersize bearing set, such as ACL's OB Series.

What else should I consider when installing main bearings?

Proper engine assembly is crucial. Ensure your crankshaft is clean and within tolerance, use the correct assembly lubricant on the bearings and journals, and always follow the manufacturer's specified torque sequence and values for the main caps.

Product Details

Doing an engine rebuild on your classic Alfa Romeo with a 1570, 1779, or 1962cc engine? These ACL H Series main bearings are a solid choice for getting your bottom end back in shape. They're designed to handle the demands of performance builds and offer a well-built replacement for your worn-out factory bearings.

ACL has been making engine bearings for a long time, and their H Series is a popular option for builds that see more than just daily driving. They use a tri-metal overlay that's known for its strength and ability to handle higher loads, which is exactly what you want when you're pushing an engine a bit harder. The standard size means they're meant to be used with a crankshaft that's still within factory tolerances, making installation straightforward if your crank is in good shape. If you're having your crank ground, you'd look for an undersize bearing set.

This set includes the main bearings needed for your engine. Make sure to check your crankshaft for any damage or wear before installation, and always follow the manufacturer's recommended lubrication and torque specifications during assembly to ensure these bearings perform as they should.
