Rear Cylinder 1Rotate the engine so that the rear piston is at Top Dead Center (TDC), compression stroke, so no load is on the valves. 2Using a 3/16″ allen wrench, remove the four screws securing the rear cylinder rocker cover. 3Remove the cover and inspect both O-ring seals. Discard if damaged or worn. 4Push both rocker arms towards the valve end support bracket (A) and using a feeler gauge check the gap between the rocker arms and the pushrod end support bracket (B). NOTE: The Rocker arm end play specification should be between 0.003″ to 0.012″. 5 Compare the measurement to the specification an determine whether adjustment is necessary. If the end play is within specification, adjustment will not be required. Refit the rocker cover (instructions 14 to 15) and carry out the same inspection on the front cylinder . If the measurement is outside the specification, adjustment will be required and shimming will be necessary (follow the remainder of these instructions). Adjustment 6Using a 1/4″ allen wrench remove the 4 screws securing the rocker shaft assembly.Refit the LH support bracket and reposition the complete assembly on the rocker base. Make sure that the three dowels are in place and the slots in the rocker shafts are properly aligned with the mounting screw holes in the RH support bracket. 11Clean the threads of the 4 support bracket screws and apply Blue Loctite to the first 4 threads. 12Fit the 1-3/4″ screws into the LH support bracket (A) and the 2″ screws to the RH bracket (B). Torque all screws in cross pattern to 16-20 foot-pounds. CAUTION: The rear piston must be at TDC, compression stroke, when tightening the support bracket screws. 13Re-check the rocker end play to ensure it is within specifica- tion. 13Lubricate the two O-rings with clean engine oil and refit them in the grooves in the rocker base. 14Refit the rocker cover.
