TIMING CASE AND DRIVE - K.5 Fig. K.8. Adaptor PD67B-1. will ensure that all backlash is taken up at T.D.C. Refit valve spring cap and collets. 2. Fit adaptor PD67B-1 (see Fig. K.8) to the fuel pump gear so that dowel of gear locates in slot of adaptor and shaft of adaptor is towards rear of engine. Secure adaptor to gear using gear securing setscrews. Fig. K.9. Marking Scribed Line on Rear of New Timing Case. 3. Release screw (5) of timing tool MS67B (see Fig N.10) and remove splined shaft. 4. Ensure slotted pointer (2) of timing tool is positioned with slot to front of tool and chamfered sides of slot outwards. At this stage, slotted edge of pointer should be kept well back from front of body. Ensure that flat of washer fitted behind pointer securing screw (3) is located over pointer. 5. Release the bracket locking screw (4) and set bracket so that the chamfered edge is in line with the relevant engine checking angle (see Page B.11). 6. Pressing fuel pump gear and adaptor towards rear, with the fuel pump gear timing mark located correctly with the idler gear timing mark, locate splined shaft of adaptor into timing tool with master spline engaged and adaptor shaft in timing tool with rear face of adaptor abutting front face of timing tool. 7. Move tool forward, complete with gear so that register of tool locates in pump aperture of timing case. If pointer is 180° out, then engine is on wrong stroke and tool should be removed and engine set on correct stroke. Fig. K.10. Removing the Fuel Lift Pump. 8. Slide slotted pointer forward to reach rear face of timing case and lock in position. 9. Take up backlash by turning tool against normal direction of rotation (shown on pump nameplate) and mark the scribed line on the rear of the timing case to coincide with the centre of the slot in the pointer (see Fig. K.9). 10. Remove tool and adaptor from fuel pump gear and fit fuel pump to engine as detailed on Page N.6. To Remove the Camshaft and Tappets Camshaft end float is controlled by a thrust plate located in a recess machined in the front face of the cylinder block. The plate is dowelled to
