If the wheel is stuck, use a hub puller rather than a hammer to avoid bending the blower wheel. Always sand the new motor shaft lightly and apply a thin coat of anti-seize lubricant; this makes the next motor change significantly easier and prevents the wheel from becoming permanently fused to the shaft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCross-Reference \u0026amp; Compatibility:\u003c\/strong\u003e The 51-101728-05 is a direct OEM replacement for the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e 51-101728-05, 51-24373-23, 51-24373-11, 51-24373-04\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eFasco \/ Emerson Refs:\u003c\/strong\u003e K55HXKNE-9148, MOT-51-101728-05\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRheem\/Ruud Air Handlers:\u003c\/strong\u003e RHLA, RHLB, RHLL, RHLN, RHPL, RHPN\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSeries Units:\u003c\/strong\u003e RHLL-HM2417JA, RHLL-HM3017JA, RHLN-HM2417JA, RHPN-HM2417JA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSpecific Unit Variations:\u003c\/strong\u003e RHLL-HM2417JA, RHLA-HM2417JA, RHPL-HM2417JA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Rheem","offers":[{"title":"Default Title","offer_id":53191640908139,"sku":"662766328899","price":460.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/51-101728-05.jpg?v=1778188037","url":"https:\/\/tophvacparts.com\/products\/protech%e2%84%a2-51-101728-05-genuine-oem-indoor-blower-motor-1-2-hp-208-230v-1075-rpm","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
