 1. Place a Countersunk Washer (172) over each of the 5-40 x 1/2"

Flat-Head Screws.

 2. Position the engine in the Chassis (19) and line up the holes in

the Engine Mounts (164) with the slots in the Chassis.

IMPORTANT NOTE: Use a Thread-Lock compound on the

threads of the screws in the Engine Mounts to keep them from com-

ing loose.

 3. Thread the 5-40 x 1/2" Flat-Head Screw (173), with the Washers

in place, all the way into each of the four holes in the Engine Mounts.

Be sure all the Countersunk Washers fit down inside the slots in the

Chassis. Do not fully tighten the Screws yet.

 1. Adjust the Gear mesh between the Clutch Bell (159) and the

Spur Gear (91) by sliding the Engine Mounts (164) in the slots of the

Chassis (19). In order to function properly, the Gears should be as

close as possible, but still have a small amount of backlash (space

between the Gear teeth). You should be able to rock one Gear back

and forth slightly while holding the other one steady. Be sure to

check the Gear mesh all the way around the Spur Gear.

 2. Once the engine alignment and Gear mesh are correct, tighten

all of the Screws (173). Re-check the Gear mesh after all the Screws are

tight to ensure the Engine Mounts did not move.

Place a piece of paper between the Clutch Bell Gear

and Spur Gear, Slide the engine forward until the paper is pinched

between the Gears and Tighten the Engine Mounting Screws. This

will give a small amount of space between the Gears for proper mesh.
