Made from high-grade aluminum alloy with upgraded welding for improved sealing, it matches the fit and function of OEM part numbers AR42940, AR42518, and AR3061 for 2.2 GPM units. Note: this unit is intended only for 2.2 GPM pumps and is not compatible with higher-flow SRMW 2.3–2.5 GPM models.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this pump head restore lost pressure and stop leaks?\u003c\/h3\u003e\n\u003cp\u003eThe assembly uses upgraded welding and tighter cast tolerances to improve the seal around internal passages, preventing common leak points.

Using this head on higher-flow pumps may cause damage or leaks because the part is only rated for 2.2 GPM operation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDo not install on SRMW 2.3G28, 2.4G28, or 2.5G28 models.\u003c\/li\u003e\n  \u003cli\u003eCheck current pump flow (2.2 GPM required) before ordering.\u003c\/li\u003e\n  \u003cli\u003eFollow torque specs and seal\/gasket replacement recommendations during install.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for? This JDMSPEED AR42940 pump head assembly is for Troy-Bilt owners and independent service technicians who need a robust, OEM-compatible replacement for 2.2 GPM pressure-washer pumps. Choose this part if you want a cost-effective fix for pump leaks, reduced pressure, or a failing pump head without replacing the entire pump. If your machine is rated above 2.2 GPM, select a compatible higher-flow assembly instead to avoid performance problems.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this pump head work on my SRMW 2.5 GPM model?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This JDMSPEED head is only compatible with 2.2 GPM pumps; it is not suitable for SRMW 2.3–2.5 GPM units.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What is the maximum pressure rating for this replacement head?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The pump head is rated up to 2800 PSI and designed for pumps with a 2.2 GPM flow rate.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"JDMSPEED","offers":[{"title":"Default Title","offer_id":56822197322068,"sku":"B0GQSKN44R","price":68.24,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/jdmspeed-front-view-pump-head.jpg?v=1786971834","url":"https:\/\/gardenluxe.co.uk\/products\/jdmspeed-pressure-washer-pump-head-assembly-for-troy-bilt-rmw-2-2-gpm-aluminum-direct-fit-ar42940-replacement","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
