NOTE
• In removing and applying the bolts and nuts marked with “ * ”, a pneumatic wrench or similar pneumatic
tool, if employed, must be used with enough care not to get them sized.
• For * marked screws, bolts and nuts on the table, apply engine oil to their threads and seats before
tightening.
• The letter “M” in Size × Pitch means that the screw, bolt or nut dimension stands for metric. The size is
the nominal outside diameter in mm of the threads. The pitch is the nominal distance in mm between two
threads.
