ACL Bearings 5M2817-1.00 Main Bearing Set 1.00mm Oversize for Isuzu

The ACL Bearings 5M2817-1.00 is a precision-engineered main bearing set designed for Isuzu G-series engines including the G130, G161, G161Z, G180Z, and G200Z models produced from 1963 through 1986. This set features 1.00mm oversize bearings specifically manufactured for crankshafts that have been reground 1.00mm undersize during rebuilding or reconditioning.

Key Features:

• Premium bimetal (aluminum-based) bearing construction for superior wear resistance
• 1.00mm oversize specification compensates for material removed during crankshaft grinding
• Engineered with tight wall thickness tolerances for consistent bearing clearances
• Manufactured to OEM replacement standards for reliable fitment and performance
• Complete main bearing set for engine rebuilding applications

ACL bearings are manufactured in Tasmania, Australia with over 70 years of precision bearing production experience. These bearings feature aluminum-tin-silicon alloy composition that provides exceptional strength, excellent load-carrying characteristics, and outstanding seizure resistance. The precise manufacturing tolerances ensure proper oil film formation and optimal engine protection during operation.

Application Note: This oversize bearing set is intended for use with crankshafts that have been professionally machined 1.00mm undersize. The thicker bearing shells compensate for the material removed from the crankshaft journals, maintaining proper bearing clearances essential for engine longevity and performance.
