Product Description<\/h2>\n\n\n\n

Sourcing Marine<\/strong> provides a superior alternative to traditional pneumatic valve grinding. Our manual reaming tool is specifically designed for the maintenance of 4-stroke diesel engine cylinder heads. It solves the common industry problems of uneven seat wear, poor sealing, and low maintenance efficiency.<\/p>\n\n\n\n

The 4-Step Precision Reaming Process<\/strong><\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Our toolset includes four specialized reamers to achieve a factory-standard finish:<\/p>\n\n\n\n

    \n
  1. Angle Reamer (No. 1):<\/strong> Matches the exact sealing angle of your valve seat to remove deep corrosion and carbon deposits.<\/li>\n\n\n\n
  2. Width Adjustment (No. 2):<\/strong> Used to trim the seat profile and manage the overall width of the sealing surface.<\/li>\n\n\n\n
  3. Contact Finisher (No. 3):<\/strong> Specifically grinds the precise contact face where the valve spindle meets the seat.<\/li>\n\n\n\n
  4. Top-Surface Refinement (No. 4):<\/strong> Adjusts the upper boundary of the seat to ensure the contact width remains within the optimal 2.5mm\u20133.5mm<\/strong> range.<\/li>\n<\/ol>\n\n\n\n

    Technical Compatibility<\/strong><\/h3>\n\n\n\n

    We provide customized tool dimensions tailored to your specific engine model. Our kits are widely used for:<\/p>\n\n\n\n

      \n
    • YANMAR:<\/strong> All medium-speed 4-stroke series.<\/li>\n\n\n\n
    • DAIHATSU:<\/strong> DK, DC, and DL series.<\/li>\n\n\n\n
    • MAN:<\/strong> L+V 20\/27, 23\/30, 28\/32, and 32\/40 series.<\/li>\n\n\n\n
    • WARTSILA-SULZER:<\/strong> AS, AT, and Z-type engines.<\/li>\n<\/ul>\n\n\n\n

      Operation Advantages<\/strong><\/h3>\n\n\n\n
        \n
      • Consistency:<\/strong> Avoids the “running-away” effect of pneumatic tools, ensuring the seat stays concentric to the valve guide.<\/li>\n\n\n\n
      • Longevity:<\/strong> By controlling the cutting depth, you preserve more material on the seat insert, allowing for more overhaul cycles before replacement is needed.<\/li>\n\n\n\n
      • Ease of Use:<\/strong> The tool is designed to be inserted directly into the valve stem guide bush, ensuring perfect alignment every time.<\/li>\n<\/ul>\n","protected":false},"featured_media":961,"template":"","product-category":[14],"product-tag":[],"class_list":["post-951","product","type-product","status-publish","has-post-thumbnail","hentry","product-category-specialized-tools"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/product\/951","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/media\/961"}],"wp:attachment":[{"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/media?parent=951"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/product-category?post=951"},{"taxonomy":"product-tag","embeddable":true,"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/product-tag?post=951"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
