pump<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">On excavators the main pump is almost always a variable displacement <a href=\"https:\/\/www.tfsoleodinamica.it\/en\/catalog\/piston-pumps\/\">axial piston pump<\/a>, often in tandem configuration: two pumps on the same shaft that together feed boom, arm, bucket, swing and travel. It is the hardest-working component on the machine, and when it fails the excavator stops. TFS overhauls excavator pumps from the main manufacturers, including <a href=\"https:\/\/www.tfsoleodinamica.it\/en\/partner\/kawasaki\/\">Kawasaki<\/a> (K3V, K3VL, K5V) and <a href=\"https:\/\/www.tfsoleodinamica.it\/en\/partner\/bosch-rexroth\/\">Bosch Rexroth<\/a> (A8VO), and tests them on the bench before return.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Signs that the pump needs an overhaul<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Slow or weak movements, especially when several functions are combined<\/li><li>Diesel engine losing revs or stalling under load: often the pump no longer regulates the power it absorbs<\/li><li>Abnormal noise, whining or vibration around the pump<\/li><li>Oil running hotter than usual and metal particles in the filters<\/li><li>Increased case drain flow, a sign of internal leakage<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The pump is not always to blame: a relief valve discharging, a worn control valve or a fault in the pilot circuit produce similar symptoms. This is why diagnosis starts from the machine and from measurements, not from replacement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Kawasaki K3V, K3VL and K5V pumps<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On Kawasaki K3V, K3VL and K5V pumps the failure we see most often concerns swash plate lubrication: when it fails, the swash plate seizes, the pump can no longer vary its displacement and the machine does not respond as it should. TFS is a <strong>Kawasaki Authorized Service Centre<\/strong>: it works to the manufacturer\u2019s specifications with genuine parts, and repairs on Kawasaki pumps are covered by a 12-month warranty.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How we work on an excavator pump<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The pump is dismantled, washed and measured component by component: pistons and slippers, cylinder block, valve plate, swash plate, bearings and regulator. Whatever is out of tolerance is replaced, the pump is reassembled to the manufacturer\u2019s specifications and the regulator is set. Testing follows on the <a href=\"https:\/\/www.tfsoleodinamica.it\/en\/services\/test-bench\/\">pump test bench<\/a>, up to 470 bar and 600 l\/min, with a report of the measured values.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One piece of advice we always give: after a pump failure, before refitting it, the circuit must be cleaned and the oil and filters replaced. Metal debris from the failed pump, left in the system, quickly ruins even a freshly overhauled pump. When needed we work directly on site with our <a href=\"https:\/\/www.tfsoleodinamica.it\/en\/services\/on-site-support\/\">on-site support<\/a>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">For a repair service or to verify the feasibility of repairing a specific component, contact the TFS technical team: we will respond within 24 business hours with an estimate of the time and cost of the repair.<\/p>\n\n\n<\/div><\/div>\n\n<style>.kadence-column559_col_sidebar > .kt-inside-inner-col{border-top-width:0px;border-right-width:0px;border-bottom-width:0px;border-left-width:0px;}.kadence-column559_col_sidebar > .kt-inside-inner-col{column-gap:var(--global-kb-gap-sm, 1rem);}.kadence-column559_col_sidebar > .kt-inside-inner-col{flex-direction:column;}.kadence-column559_col_sidebar > .kt-inside-inner-col > .aligncenter{width:100%;}.kadence-column559_col_sidebar > .kt-inside-inner-col:before{opacity:0.3;}.kadence-column559_col_sidebar{position:relative;}@media all and (max-width: 1024px){.kadence-column559_col_sidebar > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}@media all and (max-width: 767px){.kadence-column559_col_sidebar > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}<\/style>\n<div class=\"wp-block-kadence-column kadence-column559_col_sidebar tfs-partner-sidebar\" id=\"tfs-partner-form\"><div class=\"kt-inside-inner-col\">\n\n<h4 class=\"wp-block-heading has-text-align-center\" style=\"color:#305473;\">Contact our representative<\/h4>\n\n\n<div class=\"wp-block-image tfs-referente-photo\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"491\" height=\"491\" src=\"https:\/\/www.tfsoleodinamica.it\/wp-content\/uploads\/2026\/04\/Angelo-Pagano-4_1.png\" alt=\"Angelo Pagano - Titolare TFS Oleodinamica\" class=\"wp-image-268\" style=\"width:80px\" srcset=\"https:\/\/www.tfsoleodinamica.it\/wp-content\/uploads\/2026\/04\/Angelo-Pagano-4_1.png 491w, https:\/\/www.tfsoleodinamica.it\/wp-content\/uploads\/2026\/04\/Angelo-Pagano-4_1-300x300.png 300w, https:\/\/www.tfsoleodinamica.it\/wp-content\/uploads\/2026\/04\/Angelo-Pagano-4_1-150x150.png 150w\" sizes=\"auto, (max-width: 491px) 100vw, 491px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><strong>Angelo Pagano<\/strong>,<br>Owner and Technical Director<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">\u260e <a href=\"tel:+390828301272\">+39 0828 301 272<\/a><br>Customer Support<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">?
