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.

Fitted on either side of a main bearing, the half washers hold the crankshaft in its axial position. They work every time the clutch is disengaged, when the clutch pushes the crankshaft against them. A worn washer lets the end float increase and the crankshaft shift, at the expense of its own thrust faces.

Technical specifications

Technical guide

The lubrication grooves, present on one face of the half washer only, must face the crankshaft; the plain face rests against the block or cap. A reversed washer starves the crankshaft's thrust face of oil and damages it quickly.

Before fitting the cap, apply assembly grease to the crankshaft-side face and check that the half washers in the block are flush. The cap goes on without forcing and is then tightened according to the manufacturer's procedure. Finish by checking the end float with a dial gauge, to be compared with the manufacturer's value.

The brand
