Con rod bearing set (ACL Race Series) - 1B1663HX

The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance Trimetal engine bearings.

• High strength overlay plate with reduced thickness for improved fatigue properties
• Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
• Increased crush for improved bearing retention
• Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
• Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
• 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings.
• Tight consistent wall tolerances to help you maintain consistent clearances.
• Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.

Oil clearances are most accurately measured using micrometres and bore gauges.
Bearing wall thickness measurements are taken at 90 degrees to the partingline (i.e. at the crown of the bearing) using a micrometre with a ball anvil, for use on the curved ID of the bearing.
Vertical oil clearance is best measured by assembling the bearing in its housing, with bolts torqued to specification, then using a boregauge measure the assembled ID of the bearings at 90 degrees to the parting faces.
The mating crankshaft journal size is measured, and subtracting this measurement from the bearing ID bore size,gives the assembled oil clearance.

ACL Race Series performance engine bearings can be assembled with .00075-.001” per 1” of journal diameter (0.020-0.025mm per 25mm of journal diameter) plus .0005” (0.013mm).

As an example for a 2.000” (50mm) journal diameter, 2.000 x .001 =
.002 + .0005 = .0025” (50/25 x 0.025 = 0.050 + .013 = 0.063mm).
Bearings should not be polished with abrasive pads or paper, on the bearing surface, to change the oil clearance!
