• Clean Rags: Essential for wiping down components and keeping your work area clean.
• Parts Tray: A parts tray is helpful for keeping track of small components and preventing them from getting lost.
• Camera or Phone: Taking photos as you disassemble the clutch can be extremely helpful for reassembly. It's easy to forget the order of components, so a visual record can be invaluable.

Having all these tools readily available will make the disassembly process much smoother and more efficient. Remember, using the right tools is not only about convenience but also about preventing damage to your valuable clutch components. So, take the time to gather everything you need before you start.

Step-by-Step Disassembly Guide

Alright, with our tools all lined up, let's get down to the nitty-gritty of disassembling your OSC Secondary SC clutch. Remember to work in a clean, well-lit area, and don't hesitate to refer to your machine's service manual for specific instructions and torque specifications.

1. Initial Inspection and Cleaning: Before you start wrenching, give the clutch a good once-over. Look for any obvious signs of damage, wear, or leaks. A little pre-disassembly diagnosis can save you headaches later on. Use a clean rag to wipe off any excess grease, dirt, or debris. This will not only make the job cleaner but also allow you to better inspect the components.
2. Loosening the Clutch Bolt: The first step is to loosen the main clutch bolt. This bolt secures the clutch to the shaft. Use the appropriate socket and wrench to loosen the bolt. In some cases, the bolt may be very tight, so you may need to use a breaker bar for additional leverage. Important: Don't remove the bolt completely at this stage. Just loosen it a few turns.
3. Using the Clutch Puller: Now it's time to bring out the clutch puller. Thread the puller into the clutch. As you tighten the puller, it will press against the shaft and force the clutch off. Make sure the puller is properly aligned to avoid damaging the threads. Apply steady, even pressure until the clutch pops free. Pro Tip: If the clutch is particularly stubborn, try applying some penetrating oil to the shaft and let it sit for a few minutes before using the puller.
4. Removing the Outer Sheave: Once the clutch is off the shaft, you can remove the outer sheave. This is usually held in place by a snap ring or a series of bolts. Use snap ring pliers to carefully remove the snap ring. If there are bolts, use the appropriate socket or wrench to remove them. Gently pull the outer sheave off the clutch assembly. Important: Pay attention to the orientation of the sheave as you remove it. This will help you reassemble it correctly later on.
5. Compressing the Spring: This is where the spring compressor tool comes into play. Carefully position the compressor tool on the clutch assembly and begin to compress the spring. As you compress the spring, you'll notice the tension on the retaining bolts or snap ring decrease. Safety First: Always wear safety glasses when working with springs. If the spring compressor slips, the spring can come loose with considerable force.
6. Removing the Retaining Bolts or Snap Ring: With the spring compressed, you can now remove the retaining bolts or snap ring that holds the clutch together. Use the appropriate socket, wrench, or snap ring pliers to remove the fasteners. Important: Keep the spring compressed until all the fasteners are removed. Releasing the spring prematurely can cause damage or injury.
7. Disassembling the Clutch Components: With the retaining fasteners removed, you can now carefully disassemble the remaining clutch components. This may include the inner sheave, spring, rollers, and other small parts. Organization is Key: As you disassemble the clutch, lay the components out in an organized manner. This will make reassembly much easier. Consider taking photos or making notes to help you remember the order of the components.
8. Inspecting the Components: Now that the clutch is completely disassembled, take the time to inspect each component for wear, damage, or corrosion. Pay close attention to the rollers, bushings, and sheave surfaces. Replace any worn or damaged components. Preventative Maintenance: Replacing worn components now can prevent more serious problems down the road.

Reassembly Tips and Tricks

Alright, you've successfully disassembled your OSC Secondary SC clutch, inspected the components, and replaced any worn parts. Now it's time to put it all back together. Reassembly can be just as challenging as disassembly, but with these tips and tricks, you'll be a pro in no time.

• Cleanliness is Next to Godliness: Before you start reassembling the clutch, make sure all the components are clean and free of debris. Use a clean rag and some solvent to wipe down each part. This will ensure smooth operation and prevent premature wear.
• Refer to Your Photos and Notes: Remember those photos and notes you took during disassembly? Now's the time to put them to use. Refer to them to ensure you reassemble the clutch in the correct order.
• Lubricate the Components: Apply a thin coat of grease to all moving parts, such as the rollers, bushings, and sheave surfaces. This will reduce friction and prevent wear.
• Use the Spring Compressor Tool: When reassembling the spring, use the spring compressor tool to safely compress the spring. This will make it much easier to install the retaining bolts or snap ring.
• Torque to Spec: Use a torque wrench to tighten all bolts and nuts to the manufacturer's specified torque. This is crucial for ensuring proper clamping force and preventing loosening.
• Double-Check Your Work: Once you've reassembled the clutch, double-check your work to make sure everything is in the correct place and properly tightened. Rotate the clutch by hand to ensure it moves smoothly.

Common Issues and Troubleshooting

Even with the best preparation and instructions, you might encounter some snags along the way. Here are some common issues you might run into while disassembling or reassembling your OSC Secondary SC clutch, along with some troubleshooting tips:
