Companion Flange: Service and Repair
Companion Flange Installation
If companion flange has been removed, put new alignment marks B and C on it. Then, reassemble using the following procedure. (Perform step 4
when final drive and propeller shaft are separated from each other. Also perform step 4 when either of these parts is replaced with a new one.)
1. Erase original marks B and C from companion flange with suitable solvent.
2. Measure companion flange vertical runout.
3. Determine the position where maximum runout is read on dial gauge. Put mark (shown by B in figure) on flange perimeter corresponding to
maximum runout position.
4. Measure companion flange surface runout.
5. Determine the position where maximum runout is read on dial gauge. Put mark (shown by C in figure) on flange perimeter corresponding to
maximum runout position.
6. Position companion flange and propeller shaft using alignment marks A and B. Set the marks A and B as close to each other as possible.
Temporarily attach bolts and nuts.
7. Press down propeller shaft with alignment mark C facing upward. Then tighten the lower nut to specified torque.
8. Tighten remaining nuts to specified torque.
