When the end-face of special tool and the surface of coupling plate are contacted by inserting special tool into coupling plate, No. 1 cylinder is set at Top Dead Center of the compression stroke. SST: Supply pump tool (09512-2530)
NOTICE When the end-face of special tool and the surface of coupling plate are not contacted, No. 6 cylinder is set at Top Dead Center of the compression stroke. Rotating crankshaft once, reconfirm it with special tool.
