ACL 6M5587HX-STD is a main bearing set for the cataloged Audi DAZA, DNWA engine configurations. STD manufacturer size designation; verify the exact engine and assembled clearance.

Bearing Configuration

HX specifies 0.001 inch (0.025 mm) additional oil clearance relative to the corresponding H-STD set on the specified standard-size shaft. It is separate from any repair-size or housing-oversize designation.

ACL’s 2023 application guide places this main-bearing family in five-cylinder EA855 EVO engines DAZA and DNWA. Earlier EA855 engines such as CEPA and CEPB use a separately cataloged main-bearing family. Confirm the exact engine code before pairing components.

Engine Application

Manufacturer / Engine Audi — DAZA
Manufacturer / Engine Audi — DNWA

The engine-family list identifies catalog applications, not universal vehicle fitment. Confirm the exact engine version, crankshaft, rods, block and bearing location. Vehicle names and photos do not replace dimensional verification.

Quantity and Assembly Checks

Confirm the set contents, bearing positions and any separate thrust components against the complete manufacturer number. The photo is representative of the part family.

Measure shaft journals, housing bores and assembled oil clearance using the engine builder’s specification. Check oil-hole alignment, groove placement and crankshaft fillet clearance before final assembly. Catalog standard dimensions must not be treated as the finished dimensions for a different repair size. ACL specifies that abrasive pads or paper must not be used on the bearing surface to alter oil clearance.
