Frequently Asked Questions

What is ACL part 8B663H-010?
It is the connecting rod bearing set described on this page in the exact 010 size suffix configuration.

Does vehicle fitment alone confirm the correct bearing?
No. Match the exact MPN, engine code, crankshaft version, journal dimensions, and every size or clearance suffix.

What does STD mean?
STD identifies a standard-size configuration. The crankshaft and housing must still be measured before assembly.

What does an HX or clearance suffix mean?
It identifies an MPN-specific clearance configuration. Never substitute it without measured assembly requirements.

Can bearings be installed without measuring oil clearance?
No. A qualified engine builder should measure every journal, housing bore, and assembled oil clearance with calibrated tools.

Are related bearings or thrust washers included?
Only the components and quantity stated for this exact MPN are included. Main, rod, cam, and thrust components may be sold separately.

Is this product new?
Yes. The condition is new unless the product page explicitly states otherwise.

What should I verify before checkout?
Confirm the MPN, engine application, journal size, required clearance, package quantity, coating or series suffix, and all machine-shop measurements.

Installation Instructions

  1. Confirm ACL part 8B663H-010, the engine code, crankshaft version, journal position, and required size before disassembly.
  2. Have a qualified engine machinist inspect the crankshaft and housing, then measure every journal and bore with calibrated tools.
  3. Clean all oil passages and bearing seats; never install over debris, burrs, damage, or an unverified machined surface.
  4. Check bearing orientation, oil-hole alignment, crush, side clearance, and assembled oil clearance using the engine-builder procedure.
  5. Use the specified lubricant, fastener procedure, and torque sequence, then verify free rotation and oil-system priming before startup.
  6. Monitor oil pressure and inspect for abnormal noise or contamination during initial operation and break-in.
