Installation of the retaining ring. Place the end of the retaining ring into the retaining ring groove in the piston. Using a small screwdriver press the retaining ring in place. Move around the pinhole in a circular pattern to spiral the complete retainer into the groove. Make sure the retainer is completely in the groove as it will unwind and lead to failure.\u003c\/p\u003e\n\u003cp\u003e* SOLD AS A SET OF 4\u003c\/p\u003e","brand":"Keith Black Pistons","offers":[{"title":"Default Title","offer_id":48116646215867,"sku":"KB-RRN-81-4PK","price":31.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0540\/5448\/6203\/files\/KB-RRN-81-4PK.jpg?v=1784544903"}],"url":"https:\/\/adelaidehdonline.com.au\/collections\/keith-black-pistons.oembed?page=3","provider":"Adelaide HD Bike Works","version":"1.0","type":"link"}
