DESCRIPTION:

The numerical sequence shown on the illustration is intended as a guide to dismantling K Fig 33. ( T E-26). Before removing and dismantling the pump, check the flow and pressure for each section of the pump (see Section H, Steering and Section S, Suspension – Technical Data). If the values are low, renewal of components such as gears, bearings and housings will not effect a permanent cure. If the pump output is satisfactory but there is external leakage, dismantle the pump for re-sealing only. Note: If the steering flow rate is low, make sure that there is no dirt in the end cover 12 and that the spool 10 moves freely. The size of washer 9 controls the steering flow rate (see Technical Information Bulletin 10/183). For assembly the sequence should be reversed.

When Dismantling Mark housings and covers to ensure correct re-assembly. Remove sharp edges and burrs from shafts to avoid seal damage. Remove all the seals. Keep bearing blocks 25, 27, 38, 40 and gears 26 and 39 together in sets to ensure refitting of the bearing blocks in their original positions. Inspection Clean all the components using a proprietary washing agent (do not use trichloroethylene or similar as this will damage the seals). Dry the components immediately afterwards with compressed air. Be sure to blow out the ports and cross drillings in the end cover 12. Inspect the flow control valve spool 10 for signs of wear or damage. Inspect the spool bore in end cover 12. Make sure the flow control components 1 to 10 are free from dirt. Inspect all components for damage or signs of wear.

It is normal for the gears to have cut a slight track in the body bore on the inlet (large port) side. A groove up to 0.3mm (0.01 in) deep across the full width of the gear teeth is permissible. If the wear is greater than 0.3mm (0.01 in), renew the pump. The bores and side faces of the bearing blocks and gears are coated with Teflon during manufacture. If the coating is worn away, or if the bearing surfaces are scored or damaged the pump must be renewed. If the faces of the gear teeth are damaged the pump must be renewed. DO NOT use any abrasives on the bearing blocks or gears as this would destroy critical manufacturing dimensions It is only worth reassembling (with new seals) if the body, bearings, bushes and gears are in perfect condition.
