{"product_id":"2842351307","title":"Multiquip 2842351307 Piston Ring Set 0.50 Oversize - OEM Replacement Part","description":"\u003cp\u003eThis oversize piston ring set restores compression and engine performance in Multiquip rammer engines that have been rebored 0.50mm beyond standard specifications. When cylinder wear exceeds service limits, the engine requires machining and installation of oversize piston rings to maintain the 2.4 HP output at 3,600 RPM specified for these tamping rammers. Proper ring seal is critical for maintaining the 600-695 blows per minute impact rate and 1,650-2,250 lbs. per blow compaction force that defines rammer performance.\u003c\/p\u003e\n\n\u003cp\u003eThe MT55F and MTR40F\/MTR40SF rammers utilize air-cooled 4-stroke single cylinder engines with 51mm bore and require precise ring-to-cylinder clearances for optimal compression. Loss of compression results in reduced impact force, difficulty engaging the automatic centrifugal clutch, and inability to maintain the factory-set 3,600 RPM operating speed. This 0.50mm oversize ring set is engineered specifically for engines that have been professionally rebored to restore original compression ratios.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Multiquip rammer models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMT55F\u003c\/li\u003e\n\u003cli\u003eMTR40F\u003c\/li\u003e\n\u003cli\u003eMTR40SF\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":43067097546800,"sku":"2842351307","price":156.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/2842351307.png?v=1779817002","url":"https:\/\/cce-industries.com\/products\/2842351307","provider":"CCE Industries","version":"1.0","type":"link"}
