? Michel's Tip (Magickart):

"A needle cage that breaks, it is often a marked crankshaft and a bell to change. Do not play with this room!

My Pro Council: A needle cage should never work dry. Grease it imperatively before each day of rolling.

The secret: Use high temperature lithium grease. Just enough to fill the interstices between needles. Too much fat will project oil on your clutch trim and will save it! "

?️ Tuto: How to replace your clutch needle cage?

1. Disassembly: Remove the tray nut and clutch bell.

2. Cleaning the crankshaft: Use brake cleaner for the range of the crankshaft to be perfectly clean and smooth.

3. Lubrication of the cage: Apply a thin layer of specific grease to the new INA 15x19x17 cage.

4. Installation: Slide the cage on the crankshaft. It must slide freely without any hard point.

5. Reassembly: Replace your clutch bell over, then the washer and nut.

6. Test: Once the nut tight, check that the bell rotates freely by hand with a minimum of lateral game.
