8.2.9
Move the Right Single Bearing Bracket (Figure 4 item 5) into position on the backside of Saddle (Figure 4 item 1), while
moving Ring Gear (Figure 4 item 3) as needed so the teeth of the Pinion Gear (Figure 5 item 4) of the Right Single

8.2.11 Adjust the Pinion Gear (Figure 5 item 4) of the Right Single Bearing Bracket Assembly (Figure 4 item 5) so there is
.005” to .007” gap between the Pinion Gear and the teeth of Ring Gear (Figure 4 item 3).
8.2.12 Tighten all 3/8-16 x 7/8” Hex Head Cap Screws (Figure 4 item 10) that hold the Right Single Bearing Bracket Assembly
(Figure 4 item 5) in position on the Saddle (Figure 4 item 1) with a 9/16” wrench.
8.2.13 Place the Left Single Bearing Bracket Assembly (Figure 4 item 4) in a vise.
8.2.14 With a 5/32” / 4mm diameter drift punch, remove 3/16” x 1 ½” long Spring Pin (Figure 5 item 11) from the sprocket
(Figure 5 item 2) and 3/16” x 1” long Spring Pin (Figure 5 item 10) from the Pinion Gear (Figure 5 item 4).
NOTE: Save 3/16” x 1 ½” long Spring Pin (Figure 5 item 11) and 3/16” x 1” long Spring Pin (Figure 5 item 10) for reuse
at a later time.
8.2.15 With a 5/32” Allen wrench, loosen the Socket Set Screw (Figure 5 item 7) in the Sprocket (Figure 5 item 2) of the Left
Single Bearing Bracket Assembly (Figure 4 item 4).
8.2.16 Remove the Sprocket (Figure 5 item 2) from the Axle (Figure 5 item 3) of the Single Bearing Bracket Assembly (Figure
5).
8.2.17 With a 1/4" / 6mm drift punch, drive the Axle (Figure 5 item 3) / Pinion Gear (Figure 5 item 4) assembly out of the Left
Single Bearing Bracket Assembly (Figure 4 item 4).
8.2.18 With a 1/4" / 6mm drift punch, drive Axle (Figure 5 item 3) out of Pinion Gear (Figure 5 item 4).
8.2.19 Press the new Axle (Figure 5 item 3) into Pinion Gear (Figure 5 item 4).
8.2.20 Using the existing hole in the Pinion Gear (Figure 5 item 4) as a guide, drill a 3/16” / 4.7 mm hole completely through
the Axle (Figure 5 item 3).
8.2.21 Install the 3/16” x 1” long Spring Pin (Figure 5 item 10) in the 3/16” / 4.7mm hole.
8.2.22 Press the Axle / Pinion Gear assembly into the Left Single Bearing Bracket Assembly (Figure 4 item 4).
8.2.23 Place the Sprocket (Figure 5 item 2) on the Axle (Figure 5 item 3) with the hub of the Sprocket facing outward.
8.2.24 Place the new Drive Chain (Figure 4 item 15) on the Sprocket (Figure 5 item 2) of the Left Single Bearing Bracket
Assembly (Figure 4 item 4) and the Double Sprocket (Figure 6 item 4) of the Double Bearing Bracket Assembly (Figure
4 item 6).
8.2.25 When placing the Left Single Bearing Bracket Assembly (Figure 4 item 4) in position on the Saddle (Figure 4 item 1),
rotate the Pinion Gear (Figure 5 item 4) so the teeth mesh in the teeth of Ring Gear (Figure 4 item 3).
8.2.26 Install the 3/8-16 x 7/8” Hex Head Cap Screws (Figure 4 item 10) and 3/8” Washers (Figure 4 item 12) through the Left
Single Bearing Bracket (Figure 4 item 4) and screw them into the Saddle (Figure 4 item 1) finger tight.
8.2.27 There should be a .005” to .007” gap between the Pinion Gear (Figure 5 item 4) and the teeth of Ring Gear (Figure 4
item 3). Make sure the Pinion Gears (Figure 5 item 4) of the Single Bearing Brackets (Figure 4 items 4 & 5) are evenly
spaced in the teeth of the Ring Gear (Figure 4 item 3).
8.2.28 Snug the 3/8-16 x 7/8” Hex Head Cap Screws (Figure 4 item 10) with a 9/16” wrench.
8.2.29 Tighten the Socket Set Screw (Figure 5 item 7) in the Sprocket (Figure 5 item 2) of the left Single Bearing Bracket
(Figure 4 item 4) with a 5/32” Allen wrench.
8.2.30 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 item 4) of the Right and Left Single Bearing Bracket Assemblies (Figure 4 items 4 & 5) into the
Ring Gear (Figure 4 item 3).
8.2.31 Adjust the Pinion Gear (Figure 5 item 4) 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 4) 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 Gears (Figure 5 item 4)
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.
8.2.32 Tighten the Hex Head Cap Screws (Figure 4 item 10) on both sides of the Left Single Bearing Bracket Assembly (Figure
4 item 4) with a 9/16” wrench.
8.2.33 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 4) 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.
