Loosen 3/8" flange lock nut(#1) and drive tensionsprocket (#2). Remove drive chain (#3) from speedchange sprocket (#6).2. Remove 5/8" nut (#4) and 5/8" flat washer (#5).3. Pull idler sprocket (#8) away from drivenchain (#7) and remove driven chain.4. Rearrange speed change sprocket (#6) so that thelarger 35 tooth sprocket is in front of the smaller 19tooth sprocket as shown.5. Secure sprocket with 5/8" flat washer (#5) and5/8" - 11 nut (#4). Tighten nut to correct torque.6. Drive chain (#3) should be 73 pitches long and drivenchain (#7) 92 pitches long. If driven chain has 101pitches, remove 8 pitches from it and add those 8pitches to the drive chain.7. Replace 93 pitch driven chain (#7) first and then the73 pitch drive chain (#3).8. Make sure idler sprocket (#8) is pressing against thedriven chain.9. Retention drive chain (#3) by pressing down on idlersprocket (#2). When tensioned properly, tighten 3/8"flange lock nut (#1) to maintain that tension.Low Range Speed Change & Chain PitchesFigure 3-52493535T SprocketIn Front Of19T SprocketNo. 40 Chain64 + 8 + Offset Link= 73 Chain PitchesNo. 40 Chain92 + Offset Link= 93 Chain Pitches3782164 5
