It is sourced directly from Wacker Neuson as part number 5100038544 and fits the RD12A-90 crankshaft assembly location.\u003c\/p\u003e\u003cp\u003eCrankshaft replacement is typically required when inspection reveals excessive journal wear, scoring, cracking, or bearing failure that results in abnormal engine noise, vibration, or loss of compression. Because the crankshaft operates under continuous high-load cycling in compaction equipment, proper installation must include verification of bearing clearances, correct torque on all fasteners, and confirmation that oil passages are clear before reassembly. Always follow the engine teardown and rebuild procedures outlined in the applicable Wacker Neuson service manual to ensure correct alignment and fit.\u003c\/p\u003e\u003cp\u003eCompatible models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eRD12A-90\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43398762987568,"sku":"WACKER-5100038544","price":864.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5100038544.jpg?v=1784074558","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-crankshaft-5100038544-for-rollers","provider":"CCE Industries","version":"1.0","type":"link"}
