A hard or cracked seal lets air into the crankcase, and the saw runs lean, will not hold an idle and eventually scores its piston. Compare the new seals with the old ones, note which way each lip faces, press them in square, oil the lips, and pressure and vacuum test the crankcase before running the saw.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCRANKSHAFT SEALS - The oil seals that close the crankcase at each end of the crankshaft.\u003c\/li\u003e\n\u003cli\u003eFITS STIHL 028, 028AV, 028WB AND 028 SUPER - Compare the new seals with the old ones before fitting, and note which end each came from.\u003c\/li\u003e\n\u003cli\u003eWHY SEALS GO - A hard or cracked crankshaft seal lets air into the crankcase. The saw runs lean, will not hold an idle or a tune, revs and hangs, and in time scores its piston.\u003c\/li\u003e\n\u003cli\u003eFITTING THEM - Note which way the lip faces, pull the old seal without levering on the bearing, and press the new one in square on its outer edge. Oil the lip before the crankshaft goes through.\u003c\/li\u003e\n\u003cli\u003eTEST BEFORE IT RUNS - Pressure and vacuum test the crankcase once the seals are in. It is the only way to know the leak is gone, and it costs much less than a piston.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lil Red Barn","offers":[{"title":"Default Title","offer_id":68009617817754,"sku":"UW-QTJS-L58F","price":9.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0397\/2346\/6909\/files\/71kqUNGxaNL.jpg?v=1793382841","url":"https:\/\/performancesawsupply.com\/products\/compatible-with-stihl-028-028av-028wb-028-woodboss-028-super-crankshaf-uw-qtjs-l58f","provider":"Performance Saw Supply","version":"1.0","type":"link"}
