Flat tappet cams are ground with a small angle in the lobes that puts a side load on the camshaft. Without this a camshaft has a natural tendency to move or walk, out of the block when rotating. Roller cam lobes can't be ground that way so engines originally equipped that way usually use a retainer plate to secure them. The camshaft button serves the same purpose, but it does so by contacting the timing cover to prevent further movement.  A worn or missing cam thrust bumper will result in too much end play, resulting in timing issues.","brand":"Mr Gasket","offers":[{"title":"Default Title","offer_id":51746272510273,"sku":"BCZG_1183","price":14.3,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/1289\/6321\/files\/1183.jpg?v=1779252345"},{"product_id":"mr-gasket-cam-button-1181","title":"Mr. Gasket Cam Button","description":"These Mr. Gasket cam buttons are an absolute necessity for roller cam installations and useful to maintain accuracy in any cam installation.
