Crankshaft thrust washers Suzuki M16A

The Suzuki M16A four-cylinder

The M16A is a 1.6 litre (1586 cc) Suzuki inline four-cylinder with an aluminium block, double overhead camshafts, 16 valves and a timing chain, introduced in 2001. It powers the Suzuki Liana, Swift, SX4, Grand Vitara, Vitara and Jimny, among others, as well as the Fiat Sedici. These thrust washers are offered for this engine in a single version: the original size, uncoated.

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.

The crankshaft is held between these half washers, which limit its movement along its axis. Each time the clutch is disengaged, the clutch thrust pushes it against them, and the thrust face then works on a thin oil film. Once worn, they let the end float grow: the crankshaft moves and its own thrust faces get damaged in turn.

Technical specifications

Technical guide

Only one face of each half washer carries lubrication grooves: it goes against the crankshaft, the plain face against the block or cap. Fitted the other way round, the washer no longer lubricates the crankshaft's thrust face, which then wears very quickly.

On assembly, coat the crankshaft-side face with assembly grease, make sure the half washers seated in the block sit flush, then fit the cap without forcing it and tighten it following the manufacturer's procedure. Finally measure the end float with a dial gauge and check it against the manufacturer's value.
