What does the '1.0' size designation mean for these bearings?

The '1.0' in MB534AM1.0 indicates that these main bearings are 1.0mm undersize. This means they are designed to be used when the engine's crankshaft has been machined down by 1.0mm to correct for wear or damage.

What is the construction material of these bearings?

These bearings feature a bimetal construction, utilizing an aluminum base. This type of material is chosen for its ability to handle the loads and heat generated within the engine's bottom end.

Are these bearings a direct replacement for all L18 engines?

This specific main bearing set is designed for the Datsun L18 engine and fits several Nissan models from 1968 to 1974. Always confirm your specific vehicle's fitment and engine code to ensure compatibility.

Product Details

If you're rebuilding the bottom end of your Datsun L18 engine, these bearings are a critical part of getting it right.

This set is designed to fit a range of Datsun and Nissan vehicles from the late 60s through the mid-70s, including the popular 510 models.
