9.1.11 If entry of the Pinion Gear (Figure 6 item 3) of the Single Bearing Bracket (Figure 6) and the Pinion Gear (Figure 7 item
2) Double Bearing Bracket (Figure 7) into the Ring Gear (Figure 5 item 3) is satisfactory; tighten the 2
nd
Set Screw
(Figure 6 item 7) in the Sprocket (Figure 6 item 2).
9.1.12 Place the Hex Nuts (Figure 5 item 13) over the threaded holes nearest the center of the Saddle (Figure 5 item 1).
Place the Tie Rod Handle (Figure 5 item 6) over Hex Nuts (Figure 5 item 13) located over the threaded holes in the
Saddle (Figure 5 item 1) and line up with the holes in the Single and Double Bearing Bracket Assemblies (Figure 5 item
4 & 5) and install and tighten the Hex Head Cap Screws (Figure 5item 10 & 11) and Hex Nuts Figure 5 item 12) using a
1/2" wrench.
9.1.13 Rotate the Ring Gear (Figure 5 item 3) one (1) full revolution in the clockwise and counterclockwise direction checking
the entry of the Ring Gear (Figure 5 item 3) into the Pinion (Figure 6 item 3) of the Single Bearing Bracket (Figure 6)
and the Pinion Gear (Figure 7 item 2) Double Bearing Bracket (Figure 7) to insure the entry of the Pinion Gears into
the Ring Gear is smooth and without hesitation.
9.1.14 The machine is now ready for the cutting operation.
9.2 Installation of a New Drive Chain
9.2.1
Remove the Tie Rod Handle (Figure 5 item 6) as described in 9.1.1. With a 1/2” wrench loosen the Hex Head Cap
Screw (Figure 5 item 9) to the left of the Single Bearing Bracket (Figure 5 item 4) as viewed from the rear of the
machine.
9.2.2
With a 1/2” wrench loosen and remove Hex Head Cap Screw (Figure 5 item 9) to the right of the Single Bearing
Bracket Assembly (Figure 5 item 4) as viewed from the rear of the machine.
9.2.3 Tilt the Single Bearing Bracket (Figure 5 item 4) toward the center of the machine and remove the old drive chain
(Figure 5 item 16).
9.2.4
With an 1/8” allen wrench loosen the both Socket Set Screws (Figure 6 item 7) in the Sprocket (Figure 6 item 2) of the
Single Bearing Bracket (Figure 6).
9.2.5
Rotate the Sprocket (Figure 6 item 2) on the axle (Figure 6 item 4) of the Single Bearing Bracket (Figure 6) until it
rotates freely on the axle.
9.2.6 Place the new chain (Figure 5 item 16) over the sprocket of the Crank Gear and Sprocket Assembly (Figure 7 item 4) of
the Double Bearing Bracket Assembly (Figure 7).
9.2.7 Place the chain (Figure 5 item 16) over the sprocket (Figure 6 item 2) of the Single Bearing Bracket Assembly (Figure
6).
9.2.8
Rotate the Single Bearing Bracket Assembly (Figure 6) clockwise while rotating the Pinion Gear (Figure 6 item 3) so
that it meshes into the Ring Gear (Figure 5 item 3).
9.2.9
Insert the Hex Head Cap Screw (Figure 5 item 9) in the hole on the right of the Single Bearing Bracket Assembly
(Figure 5 item 4) and hand tighten only at this time.
9.2.10 With a 1/2” wrench tighten, the Hex Head Cap Screw (Figure 5 item 9) to the left of the Single Bearing Bracket
Assembly (Figure 5 item 4) as viewed from the rear of the machine.
9.2.11 Adjust teeth of the Pinion Gear (Figure 6 item 3) of the Single Bearing Brackets (Figure 6) and the Pinion Gear (Figure
7 item 2) of the Double Bearing Bracket (Figure 7) so they are evenly spaced in the teeth of the Ring Gear (Figure 5
item 3). There should be no more than 005”/ .12mm of play between the Pinion Gear (Figure 6 item 3) of the Single
Bearing Bracket (Figure 6) or the Pinion Gear (Figure 7 item 2) of the Double Bearing Bracket (Figure 7) and the Ring
Gear (Figure 5 item 3).
NOTE: If the desired chain tension cannot be attained it may be necessary to adjust the Double Bearing Bracket in the
same manor.
9.2.12 With a 1/2” wrench tighten Hex Head Cap Screw (Figure 5 item 9) to the right of the Single Bearing Bracket (Figure 5
item 4).
9.2.13 Tighten 1 of the Socket Head Set Screws (Figure 6 item 7) in the Sprocket (Figure 6 item 2) of the Single Bearing
Bracket Assembly (Figure 6) to fix it to the Axle.
9.2.14 Rotate the Ring Gear (Figure 5 item 3) one (1) full revolution in the clockwise and counterclockwise direction checking
the entry of the Ring Gear into the Pinion Gear (Figure 6 item 3) of the Single Bearing Bracket (Figure 6) and the Pinion
Gear (Figure 7 item 2) of the Double Bearing Bracket (Figure 7).
NOTE: The entry of the Pinion Gears into the Ring Gear should be smooth and without hesitation.
NOTE: The Pinion Gear (Figure 6 item 3) of the Single Bearing Bracket (Figure 6) and the Pinion Gear (Figure 7 item 2)
of the Double Bearing Bracket (Figure 7) should be evenly spaced in the teeth of the Ring Gear (Figure 5 item 3).
There should be no more than .005” play between the Pinion Gears and the Ring Gear (Figure 5 item 3).
9.2.15 Reinstall the Tie Rod Handle (Figure 5 item 6) as mentioned in 9.1.12.
