What does the +0.75mm sizing mean for this main bearing set?

The +0.75mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.75mm. This is a common practice during engine rebuilds to address wear or damage on the crankshaft.

What is the construction material of these main bearings?

These main bearings are made with a bimetal construction, which features an aluminum base. This material is chosen for its effectiveness in supporting the crankshaft and maintaining proper oil pressure.

Are these bearings a direct replacement for all Opel 1.7D engines?

This set is specifically sized at +0.75mm, meaning it's for engines where the crankshaft has been machined to that undersize. Always confirm your crankshaft journal size before ordering to ensure proper fitment and oil clearance.
