Buying guide and details

Main bearings hold the crankshaft in the engine block, on an oil film. The set is chosen by engine code and by journal size: STD for a factory crankshaft, 0.25 or 0.50 after regrinding.

How to read the size

  • STD: journals at the factory size.
  • STD HX: journals at the factory size, with 0.025 mm more oil clearance than the STD set. It is not an upgrade: the clearance is set by the journal and the bore.
  • 0.025, 0.25, 0.50: journals ground that much under the factory size.

Before you order

  • Choose the size from the journal measurement made by the shop that machined the crankshaft.
  • ACL sets are sold sealed by the manufacturer: check the part number and the size before you open the set.
  • The rod bearings for the same engine are in rod bearings. Crankshaft thrust washers are here too.
