Drift up to maximum sag track – 10-15 mm distance measured in the middle of the track between the bottom rollers. Sprocket tooth profile: Check for hook wear pattern at engagement face with the eye. Case drain flow of the hydraulic pump: 1.2-1.8 L/min (baseline) at operating temp when no-load. Boom foot pin boss: magnetic particle inspection (MPI) for radial crack initiation at weld toe. No tolerance to any flaw indication by any person.

303.5E: 3.5 ton of operating weight, dig depth of 3.05 m and auxiliary hydraulic flow of 60 L/min. A smaller footprint is a Balanced ‘Compact’ trade’s balance between digging power and manoeuvrability.

305.5E2: 5.4-ton class, 3.72m dig depth, 77 L/min hydraulic capacity. Ground pressure in abrasive soil is high causing greater wear of the rollers’ flange.

PC35MR: Geometry of zero tail swing, 3.24m dig depth, 3.5-ton weight.

PC60: Operating class is 6 tons, Digging depth is 3.92m, tail is conventional.

SY75C is a 24 MPa hydraulic circuit, 4.43m dig depth, 7.2 ton tier machine.

Discrepancy indicates tampering. Structural weld integrity dye penetrant test of all high cycle fatigue locations – boom foot, stick nose, Bucket link plates. If there is one crack indication, the complete unit will be refused. Cleanliness of hydraulic oil ISO 18/16/13 or better it is necessary. Undercarriage remaining life: The minimum amount of material that is still present on track shoe of grouser, on diameter of the roller tread and on the thickness of the idler wheel flange. Below threshold — negotiate on the purchase or walk away because it will be paid for with the entire replacement cost.

A list of vehicle make, model, condition, year, price and hours is further narrowed using the selection of Country, Brand, Model, Condition, Year and Price. Filters should NOT be substituted for Physical Measurement Protocol.
