The control spool is in neutral position and is connected to the hydraulic cylinder The volume of leak oil in the control block should be measured at a load pressure of 150 bar and a temperature of 50°C (in hydraulic tank).\u003cbr\u003eBefore checking the control block for leak oil, first check the secondary valves (visual inspection, with valve exchange, if this is required) and the operating cylinder (dummy), as the respective values refer only to leakage from the control spool in the control block.\u003cbr\u003eTo check the control block for leak oil from the control spool, connect a pressure sensor at the respective pressure line between the operating cylinder and the control block (use measuring equipment, if required).","brand":"Uploader","offers":[{"title":"Default Title","offer_id":53602167554379,"sku":null,"price":61.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/2519\/4315\/files\/1-71-1.png?v=1760448368","url":"https:\/\/manualbull.com\/products\/liebherr-r914-compact-r920-tier-4f-compact-excavator-service-manual","provider":"ManualBull","version":"1.0","type":"link"}
