Your rear shock eyelet hardware should always provide a snug fit between your shock and bike frame. When excessive play develops, this condition can lead to costly damage to your shock eyelets if not serviced appropriately. Preventative maintenenace of the eyelet hardware can help prevent damage to your shock.



2-Piece Reducer

img/help/page251-lSANk8/reducerproc_001_599x430-m.jpg

The two piece reducer hardware assembly is made up of two reducers, pressed into either side of a DU bushing that is pressed into the shock eyelet.

img/help/page251-lSANk8/reducerproc_001_599x430.jpg


img/help/page251-lSANk8/reducerproc_002-m.jpg

Step 1

Use a standard bolt extractor (EZ-Out or similar) to remove the two reducer pieces. Press the bolt extractor into either reducer with a counter-clockwise twisting motion, then pull while continuing to twist counter-clockwise to remove. Repeat for the second reducer.

img/help/page251-lSANk8/reducerproc_006.jpg


img/help/page251-lSANk8/reducerproc_005-m.jpg

Step 2

Remove the reducer from the bolt extractor by gently clamping the reducer and rotating the tool clockwise. If planning to reuse the reducers, make sure to avoid clamping them too tightly in your vice to keep them round.

If your reducers fit tightly in your DU bushings and remain round after removal, they can be reused. Small internal marks on the reducers from the bolt extractor are fine.
