b. Slide engine gear (1) into flywheel housing damper spline.
c. Align mounting holes in front end plate (5) with holes in flywheel
housing and secure with lockwashers and capscrews.
d. After installing on engine, check engine gear f0r runout. Maximum
eccentricity is . 005 inches at pilot roller bearing.
2. Insert two studs three inches long in two opposite bolt holes in front end
plate (5).
3. Check to be certain that pilot roller bearing (60) is properly installed in
propeller gear insi.de gear case.
4. Start reverse gear housing (3) over the two studs and slide housing over
engine gear (1) right up against flywheel housing. It may be necessary to

pinions in gear case.
5. Install lockwashers and capscrews in holes around flange of housing.
6. Remove the two studs and install remaining lockwashers and capscrews.
