Now, install a similar 90 degree bell crank to the right side. Install the steel elevator bell crank (2002-161 Bag #3) on
the right side elevator axle (2002-153 Bag #3). We suggest that you file a flat on the elevator axle where the set screw
makes contact. Put a 3x3mm set screw in the steel bell crank. Do not tighten the set screw very tightly yet, because the
exact angle will be adjusted later. When permanently tightened be sure to use a drop of locktite on the elevator bell
crank. Fit the swashplate anti rotation bracket (2002-077 Bag #3) between the upper side frames. Fit two M3x35 bolts
through the frames and the bracket. Secure them with two M3 nuts. Do not overtighten as this will only distort the
frames.
Clutch Bell Assembly
Roughen the inner surface of the clutch bell (2002-127 Bag #4 or #4M) with #220
grit sand paper. Then, clean off the debris. Trial fit the clutch lining (2002-129
Bag #4 or #4M) to the clutch bell, make sure it fits snugly. Once you are
satisfied, then remove the lining and permanently glue it back in using JB weld
Epoxy, or slow CA glue. Fit the clutch bearing (2002-131 Bag #4 or 4M) and
block (2002-081 Bag #4 or #4M) in-between the upper side frames. The ball
bearing should face downward. Use two M3x35 bolts to secure the bearing block
in place. Insert the clutch bell in the clutch bearing. It is recommended to apply
a little locktite to the pinion shaft where it inserts into the bearing.
The Pro Master has the addition of a top start system. This system is assembled
and installed as a complete unit. Start by sanding the inside of the clutch bell
(2002-303 Bag #4M) with 220 grit sandpaper to aid the bond when installing the
clutch lining. Thoroughly clean with solvent. Trim the liner so it fits snugly in the
bell. Remove and reinstall using JB weld epoxy or slow CA to hold the liner in
place. Press the 4x9x4 ball bearing (2002-103 Bag #4M) into the inside of the
clutch bell. Lightly grease the start shaft (2002-306 Bag #4M) and insert into the
clutch bell from the bottom. Take the double bearing block with ball bearing
(2002-307 bag #4M) and slip over the pinion shaft. It is advisable to use a little
Locktite on the pinion shaft where it makes contact with the ball bearing. Clean
off the end of the start shaft and slide the adapter (2002-304 Bag #4M) in place.
Install the set screws that hold the adapter in place. Take note that one of the set
screws must seat on the flat on the start shaft and Locktite must be used. Slide the
assembly into place and secure the bearing block to the frames with two M3x35
screws and nuts. Take note that the heads of these bolts must be on the same side
as the Y shaped collective bell crank.
