7.2.25 When placing the Left Single Bearing Bracket Assembly (Figure 4 item 4) in position, rotate the Pinion
Gear (Figure 5 item 3) so the teeth mesh in the teeth of Ring Gear (Figure 4 item 3).
7.2.26 Install the 3/8-16 x 3/4” Hex Head Cap Screws (Figure 4 item 11) and 3/8” Washer (Figure 4 item
14) into the Left Single Bearing Bracket (Figure 4 item 4) and screw into the Saddle (Figure 4 item 1).
7.2.27 There should be a .005” to .007” gap between the Pinion Gear (Figure 5 item 3) and the teeth of Ring
Gear (Figure 4 item 3). Make sure the Pinion Gears (Figure 5 item 3) of the Single Bearing Brackets
(Figure 4 items 4 & 5) are evenly spaced in the teeth of the Ring Gear (Figure 4 item 3).
7.2.28 Snug the 3/8-16 x 3/4” Hex Head Cap Screws (Figure 4 item 10) with a 9/16” wrench.
7.2.29 Tighten the Socket Set Screw (Figure 5 item 6) in the Sprocket (Figure 5 item 2) of the left Single
Bearing Bracket (Figure 4 item 4) with a 5/32” allen wrench.
7.2.30 Rotate the Ring Gear (Figure 4 item 3) clockwise (as viewed from the front of the machine) check the
entry of the Pinion Gear (Figure 5 item3) of the Right and Left Single Bearing Bracket Assemblies
(Figure 4 items 4 & 5) into the Ring Gear (Figure 4 item 3).
7.2.31 Adjust the Pinion Gear (Figure 6 item 3) of the Left Single Bearing Brackets (Figure 4 item 4) as
needed so that it enters the Ring Gear (Figure 4 item 3) without hesitation.
Note: When the Pinion Gears (Figure 5 item 3) of the Left and Right Single Bearing Bracket (Figure 4
item 4 & 5) enters the Ring Gear (Figure 4 item 3) it should not suddenly pull the Ring Gear. As the
Pinion Gear (Figure 5 item 3) of the Left and Right Single Bearing Bracket (Figure 4 item 4 & 5)
leaves the Ring Gear (Figure 4 item 3) it should not suddenly push the Ring Gear.
7.2.32 Tighten the Hex Head Cap Screws (Figure 4 item 11) on both sides of the Left Single Bearing Bracket
Assembly(Figure 4 item 4) using a 9/16” wrench.
7.2.33 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 Gears (Figure 5 item 3)
of the Left and Right Single Bearing Bracket (Figure 4 item 4 & 5).
Note: The entry of the Pinion Gears into the Ring Gear should be smooth and without hesitation.
7.2.34 Reattach both Tie Rod Handles (Figure 4 item 7) to the Single and Double Bearing Bracket
Assemblies (Figure 4 items 4, 5 & 6) with the Hex Head Cap Screws (Figure 4 item 10 ) and Hex Nuts
Figure 4 item 13) and tighten with a 1/2" wrench.
7.2.35 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 3) 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.
7.2.36 Drill through the Sprocket (Figure 5 item 2) and Axle (Figure 5 item 4) of the Left Single Bearing Bracket
(Figure 4 Item 4) with a 3/16” drill.
7.2.37 Install 3/16”x 1-1/4 long spring pine into the Sprocket (Figure 5 item 2).
