As rotational speeds increase under cutting load, the bushing must maintain concentricity to protect the magneto timing window and prevent uneven stator wear. Service procedures require cleaning of mating surfaces, visual inspection of the crankshaft journal for fretting or scoring, and simultaneous replacement of main shaft oil seals to restore internal lubrication pathways and exclude abrasive particulates.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSTIHL MS 170, MS 180\u003c\/li\u003e\n\u003cli\u003eSTIHL MS 250, MS 251\u003c\/li\u003e\n\u003cli\u003eSTIHL MS 270, MS 271\u003c\/li\u003e\n\u003cli\u003eSTIHL MS 362\u003c\/li\u003e\n\u003cli\u003eFits mid-production serial runs; verify rear flywheel mounting geometry and serial plate dates before purchase.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"STIHL","offers":[{"title":"Default Title","offer_id":58555688354173,"sku":"ST-0000 963 0809","price":0.92,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0565\/9190\/9056\/files\/0000-963-0809_second.jpg?v=1787126335","url":"https:\/\/ripongroundcare.com\/products\/stihl-flywheel-bushing-0000-963-0809","provider":"Ripon Ground Care","version":"1.0","type":"link"}
