{"product_id":"336009401","title":"Multiquip 336009401 Crank - OEM Replacement Part for Diaphragm Pumps","description":"\u003cp\u003eThe crank assembly converts rotational motion from the gearbox into the reciprocating motion needed to drive the diaphragm in Multiquip diaphragm pumps. This critical component works in conjunction with the connecting rod and plunger to create the pumping action that moves water through the system. When the crank fails, the pump loses its ability to generate the pressure differential required for operation.\u003c\/p\u003e\n\n\u003cp\u003eThe connecting rod bearing that interfaces with this crank requires greasing every 25 hours of operation according to Multiquip maintenance schedules. Access to the bearing is gained by removing the plunger guard. Regular lubrication of this bearing extends crank life and prevents premature failure of the entire crank assembly. Symptoms of a worn or damaged crank include excessive vibration, unusual noise from the gearbox area, loss of pumping capacity, or complete pump failure.\u003c\/p\u003e\n\n\u003cp\u003eThis crank is specifically designed for the MQD2H diaphragm pump series and maintains the precise tolerances required for proper pump operation and seal integrity.\u003c\/p\u003e\n\n\u003cp\u003eCompatible Models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMQD2H\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Multiquip OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Multiquip","offers":[{"title":"Default Title","offer_id":43066048708656,"sku":"336009401","price":241.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/336009401_7d7bee62-89cb-49db-95b9-cc9322b155dd.png?v=1779813796","url":"https:\/\/cce-industries.com\/products\/336009401","provider":"CCE Industries","version":"1.0","type":"link"}
