Knowledge for the workshop, not for the brochure.
What we know about these units, written down: field procedures with numbers, failure timelines, and the arguments we use when a customer is quoted half price for a copy.
LibraryThe animation library: the whole archiveEvery clip in the training archive, searchable by subject.Read →AnimationsPrinciples in motion: 18 animationsPumps, valves, circuits and hydraulic theory, one idea per clip.Read →Cost of ownershipA copy pump is cheaper once. A genuine pump is cheaper twice.Five years of ownership, measured on the same 20-tonne machine: purchase price, rebuilds, contamination damage and downtime. The numbers below come frRead →Field procedureSet the regulator, then read the case drain.Weak digging power with a healthy engine has two causes: a drifted regulator, or a pump bleeding internally. Four ports and one flowmeter separate theRead →Swing circuitSwing: three tests before you take the motor off.M5X and M2X swing motors are fixed-displacement swash-plate units with a built-in brake and reliefs. Weak swing is usually pressure or brake, not the Read →InstallationMost new pumps die on the first start.A unit that was correct on the bench can fail inside a week if the circuit was not flushed, the suction was not sealed, or the machine was started dryRead →
