It is always best to replace the chain and sprockets together. Otherwise, the stretched-out chain will quickly shorten the life of the new sprocket. Likewise, worn sprockets will stretch a new chain at an alarming rate.
TOOLS REQUIRED: • Red Loctite • Lint-free rag • 14mm socket • Impact wrench • 8mm T-handle • Torque wrench • 6mm Allen wrench • Fine-grit sandpaper
WHAT YOU NEED TO BUY: • Chain • Rear sprocket • Countershaft sprocket
TIME TO COMPLETE: 45-60 minutes
REPLACING A CHAIN & SPROCKETS WITH CHARLIE FLIPPEN
• Needlenose pliers • Chain measuring tool • Circlip puller (optional) • Chain breaker (optional) • 14mm open-end wrench • 32mm open-end wrench • Straight blade screwdriver
STEP 1 With the bike on the stand, loosen the sprocket bolts while the rear wheel is still on the bike (with the chain attached). This allows the sprocket bolts to loosen easier. By no means should you completely remove the sprocket bolts until the rear wheel is off the bike.
STEP 3 Remove the chain master link clip, followed by the master link. Remove the clip with a twist of a straight blade screwdriver, because it’s usually faster and it doesn’t damage the master link. Once the mas- ter link is removed, carefully remove the chain and set it aside. Do not throw it away, as you will need to measure the chain.
STEP 2 With the wheel still on the bike, remove the counter- shaft sprocket engine guard. Loosen the counter- shaft sprocket bolt, but do not completely remove it. If the countershaft sprocket uses a circlip, leave the circlip in place until Step 9.
