Service Manual for WD10 Diesel Engine intake valve (and exhaust valve) and rocker). (3) Measure the clearance between rocker and valve rod upper surface with feeler gauge. Required intake valve clearance for WD10 diesel engine is 0.3mm; while that for exhaust valve is 0.4mm. If the clearance is too large or too small, you can rotate the adjusting screw to adjust until the clearance meets the requirements. Refer to Fig. 2-9. Adjusting screw Cold-state intake valve clearance is 0.3mm Cold-state Exhaust valve clearance is 0.4mm Fig.
2-9 Intake and exhaust valve clearance (4) After checking cylinder 1 or cylinder 6, rotate the flywheel positively with external force for another 360° to let cylinder 6 or 1 in power stroke, check and adjust other valves. Table 2-4 For exhaust valve equipped with EVB auxiliary braking device, follow the steps below to adjust its clearance: (1) Rotate the flywheel until the piston is in compression stroke TDC. (2) Loosen bolt assembly 2. (3) Adjust valve clearance adjusting screw on pushrod end 10 without compressing exhaust valve rocker sealing surface until the total valve clearance is 0.4mm, and then tighten bolt assembly 2. ( ATTENTION:
In the adjusting process, you should rotate the valve clearance adjusting screw until the feeler gauge is gently infibulated, so that valve rocker piston 5 can be pushed to the bottom and no clearance between piston and piston hole bottom ). (4) Loosen bolt assembly 2. (5) Adjust bolt assembly 2, and insert a 0.25mm feeler gauge between bolt 2 and valve bridge, and tighten lockup nut at last.
