Torque Specifi cations
The following tables list the tightening torque for the major fasteners requiring use of a threadlocker.
Letters used in "emarks" column mean:
AL: Tighten the two clamp bolts alternately two times to ensure even tightening torque;
EO: Apply engine oil;
L: Apply a threadlocker to the threads;
Lh: Left-hand threads;
MO: Apply molibdenum disulfi de oil solution(mixture of engine oil and molybdenum disulfi de grease in a
weight ratio 10:1);
R: Replacement Parts;
S: Follow the specifi ed tightening sequence;
Si: Apply silicone grease (ex.PBC grease);
SS: Apply silicone sealant
