Our tool provides a controlled, perpendicular extraction force that eliminates these risks, ensuring a clean removal every time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Core Product Highlights<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Universal Fleet Compatibility:<\/strong> Custom-sized pulling heads for major 4-stroke series, including <strong>Yanmar, Daihatsu, MAN, and Wartsila-Sulzer.<\/strong><\/li>\n\n\n\n<li><strong>Hydraulic Efficiency:<\/strong> Uses a high-pressure manual hydraulic pump to generate smooth, consistent lifting force, significantly reducing man-hours.<\/li>\n\n\n\n<li><strong>Cylinder Head Protection:<\/strong> Engineered to seat securely on the head surface, distributing pressure evenly to prevent cracking or scratching.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Technical Application &amp; Operation<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Supported Engine Series<\/strong><\/h3>\n\n\n\n<p>We supply customized puller sets tailored to the specific seat geometries of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>YANMAR Series:<\/strong> EY28, EY18, N21, N18, M200, etc.<\/li>\n\n\n\n<li><strong>DAIHATSU Series:<\/strong> DK-32, DK-28, DK-20, DC-17, DL-20, etc.<\/li>\n\n\n\n<li><strong>MAN Series:<\/strong> L32\/40, L28\/32, L23\/30, L16\/24, etc.<\/li>\n\n\n\n<li><strong>WARTSILA-SULZER Series:<\/strong> L20, R22, S20, AS25, etc.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Operational Procedure (Step-by-Step)<\/strong><\/h3>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Selection:<\/strong> Based on the specific engine model, select the correct pulling head and claw pin length.<\/li>\n\n\n\n<li><strong>Positioning:<\/strong> Measure the valve seat ID and place the puller assembly over the valve seat bore.<\/li>\n\n\n\n<li><strong>Engagement:<\/strong> Position the puller claws at the lower edge of the seat or the junction between the seat and the cylinder head.<\/li>\n\n\n\n<li><strong>Tensioning:<\/strong> Turn the screw rod clockwise to expand the jaws until they are firmly engaged with the valve seat.<\/li>\n\n\n\n<li><strong>Extraction:<\/strong> Connect the high-pressure oil hose to the manual pump. Operate the pump handle to apply hydraulic lift until the valve seat is smoothly extracted from the cylinder head.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/sourcingmarine.com\/wp-content\/uploads\/2026\/03\/Hydraulic-extractor-of-valve-seat-for-marine-four-stroke-diesel-engine-1.webp\" alt=\"\" class=\"wp-image-1161\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/sourcingmarine.com\/wp-content\/uploads\/2026\/03\/Hydraulic-extractor-of-valve-seat-for-marine-four-stroke-diesel-engine-2.webp\" alt=\"\" class=\"wp-image-1162\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/sourcingmarine.com\/wp-content\/uploads\/2026\/03\/Hydraulic-extractor-of-valve-seat-for-marine-four-stroke-diesel-engine-3.webp\" alt=\"\" class=\"wp-image-1163\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/sourcingmarine.com\/wp-content\/uploads\/2026\/03\/Hydraulic-extractor-of-valve-seat-for-marine-four-stroke-diesel-engine-4.webp\" alt=\"\" class=\"wp-image-1164\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Why Choose Sourcing Marine Tools?<\/strong><\/h2>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Time Savings:<\/strong> Reduces valve seat removal time by up to 70% compared to manual methods.<\/li>\n\n\n\n<li><strong>Damage Prevention:<\/strong> Eliminates the need for &#8220;hitting&#8221; or &#8220;prying,&#8221; protecting the integrity of the cylinder head landing surface.<\/li>\n\n\n\n<li><strong>Complete Kit:<\/strong> Each set comes in a durable transport case with all necessary hydraulic components and adapters for your specific engine fleet.<\/li>\n<\/ol>\n","protected":false},"featured_media":1196,"template":"","product-category":[6],"product-tag":[],"class_list":["post-1044","product","type-product","status-publish","has-post-thumbnail","hentry","product-category-diesel-engine-parts"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/product\/1044","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\/1196"}],"wp:attachment":[{"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/media?parent=1044"}],"wp:term":[{"taxonomy":"product-category","embeddable":true,"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/product-category?post=1044"},{"taxonomy":"product-tag","embeddable":true,"href":"https:\/\/www.zhutiduoduo.com\/demo\/waimao2\/wp-json\/wp\/v2\/product-tag?post=1044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
