Primary gear thrust washers are made in varying sizes to take up the play.
Standard gap size should be between 3-6 thou. These are for the 850/998/1098cc
engines with
22A1493 Deva bush primary gear. Early 850cc had thinner tail crankshaft and different primary gear. Regret
22A321 and
22A323 are the only size available now from Rover and sometimes only available to customer order as sales are nearly non existent.
