7.2.39 Stretch the new Side Drive Chain (Figure 5 item 15) by moving the Left Single Bearing Bracket
Assembly (Figure 5 item 4) with a soft face mallet taking care to maintain the .005” to .007” gap
between the Pinion Gear (Figure 6 item 4) and the teeth of Ring Gear (Figure 5 item 3).
7.2.40 Retighten all 3/8-16 x 7/8” Hex Head Cap Screws (Figure 5 item 11) that attach the Left Single
Bearing Bracket Assembly (Figure 5 item 4) to Saddle (Figure 5 item 3).
7.2.41 Tighten the Socket Set Screw (Figure 6 item 7) in the Sprocket (Figure 6 item 2) of the left Single
Bearing Bracket (Figure 5 item 4) with a 5/32” allen wrench.
7.2.42 Install both Crank Handle assemblies (Figure 7 item 2) on the Double Bearing Bracket Assemblies
(Figure 2 item 5)
7.2.43 Rotate the Ring Gear (Figure 5 item 3) clockwise (as viewed from the front of the machine) check the
entry of the Pinion Gear (Figure 6 item 4) of the Single Bearing Bracket Assemblies (Figure 5 items 4)
into the Ring Gear (Figure 4 item 3).
7.2.44 Adjust the Pinion Gear (Figure 6 item 4) of the Single Bearing Brackets (Figure 5 item 4) as needed so
that it enters the Ring Gear (Figure 5 item 3) without hesitation.
Note: When the Pinion Gears (Figure 6 item 4) of the Left and Right Single Bearing Bracket Assembly
(Figure 5 item 4) enters the Ring Gear (Figure 5 item 3) it should not suddenly pull the Ring Gear. As
the Pinion Gear (Figure 6 item 4) of the Single Bearing Bracket Assemblies (Figure 5 item 4) leaves
the Ring Gear (Figure 5 item 3) it should not suddenly push the Ring Gear.
7.2.45 Reattach both Tie Rod Handles (Figure 5 item 6 & 7) to the Single and Double Bearing Bracket
Assemblies (Figure 5 items 4 & 5) with the 3/8-16 X 1-1/4” long Hex Head Cap Screws (Figure 5 item
12) and Washer (Figure 5 item 13) and tighten with a 9/16” wrench.
7.2.46 Rotate the Ring Gear (Figure 4 item 3) one (1) full revolution in the clockwise and counterclockwise
direction checking the entry of the Ring Gear (Figure 4 item 3) into the Pinion (Figure 5 item 4) of the
Left & Right Single Bearing Bracket Assembly (Figure 4 item 4 & 5) to insure the entry of the Pinion
Gears into the Ring Gear is smooth and without hesitation.
7.2.47 Place 3/16” drill in the 3/16” drilled hole located in the flange of the Sprocket (Figure 6 item 2) of the
left Single Bearing Bracket Assembly (Figure 6 Item 4) and drill through the Sprocket and Axle
