Crankshaft thrust washers Ford Cosworth YB and Pinto 2.0

The Ford Cosworth YB and Pinto 2.0 SOHC engines

The manufacturer lists these thrust washers for the Ford 2.0 litre Cosworth YB four-cylinder and for the Ford Pinto 2.0 SOHC. It publishes them for all models fitted with these engines. The Cosworth YB is a turbocharged inline four-cylinder of 1993 cc, introduced in 1986 on the Sierra RS Cosworth; the Pinto 2.0 is an inline four-cylinder with a cast-iron block and a belt-driven overhead camshaft.

Thrust washers

The thrust washers take the clutch thrust and set the crankshaft end float. On a modified engine with a reinforced clutch, this thrust increases. The uncoated ACL version is offered in the original size and in an oversize of 0.005 inch (+0.127 mm).

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.
