Crankshaft thrust washers Mitsubishi 6G71 6G72 6G73

The Mitsubishi 6G71, 6G72 and 6G73 V6 engines

The 6G71, 6G72 (also as 6G72-T) and 6G73 are Mitsubishi V6 engines; the G6AT is a Hyundai engine listed by the manufacturer. They are fitted to the Mitsubishi Pajero, Galant, 3000GT, GTO, Sigma and Diamante, and to the Hyundai Grandeur and Sonata, among others. These Mitsubishi 60° V6 engines displace 2.0 litres (6G71), 2.5 litres (6G73) and 3.0 litres (6G72).

Thrust washers

Thrust washers take the clutch thrust and set the crankshaft end play. On a tuned engine with a reinforced clutch, this thrust increases. The uncoated ACL version restores the thrust washers to the original size.

Technical specifications

Technical guide

Each half washer has lubrication grooves on one face. This face fits on the crankshaft side, with the smooth face towards the block or cap. Fitted the wrong way round, the washer deprives the crankshaft bearing face of lubrication and wears it quickly.

Before fitting, coat the crankshaft-side face with assembly grease. Check that the half washers in the block sit flush, fit the cap without forcing it and tighten it following the manufacturer's procedure. Then check the end play with a dial gauge and compare it with the manufacturer's value.

The brand

ACL Bearing Company, an Australian manufacturer of high-performance engine bearings since 1949, supplies uncoated thrust washers for these engines.
