PRIMARY GEAR SHIM 998 110" 112"

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 this and 22A323 are the only size available now from Rover and sometimes only available to customers order as sales are nearly non existant
