Put three pieces of 0.060 inch (1,5 mm) diameter solder (Item 2) [Figure 70-100-11] on the top of the piston. Use grease to hold them in position.

NOTE: Position the solder so they do not touch the valves.

Turn the piston to bottom dead center.

Install the cylinder head and tighten to the correct torque in the correct sequence. (See Cylinder Head Removal And Installation on Page 70-100-1.)

Turn the crankshaft until the piston exceeds T.D.C.
Remove the cylinder head.
