Kobelco ED160-5 Blade Runner and SK140SRLC-5: blade circuit and engine ratings

The ED160 blade has its own hydraulic circuit

Kobelco built the ED160 Blade Runner around a large angle-and-tilt blade. Its North American brochure describes a dedicated dozer circuit with a separate relief setting. The SK140SRLC-5 instead lists a dozer blade as optional equipment.

Finding a blade on an SK140 does not establish that it has the Blade Runner's six-way front, circuit or dozing capability.

The ED160's single blade lever controls lift, angle, tilt and float. Its blade wings also create a distinction between folded blade width, extended blade width and crawler width. The narrowest of those measurements cannot describe every part of a machine being moved through an opening.

Check the blade's actual position as well as the tracks.

Kobelco gives the Blade Runner different track-shoe and travel figures from the SK140. The ED brochure describes curved shoes for maneuvering while dozing; the SK sheet lists its triple-grouser shoe choices. Keep the specific undercarriage with the machine's drawbar and travel data instead of carrying across the shared engine's specifications.

Equal engine names conceal different front and weight arrangements

Both brochures name the Isuzu AR-4JJ1XASK-02, but separate SAE net power from output without the fan. The larger without-fan figure is not the stated net rating. Torque has the same two conditions.

A comparison that labels one machine by net output and the other by its without-fan number would create a difference the engine tables do not show.

The SK140 operating-weight table then separates shoe widths and repeats the calculation with its optional dozer. The ED160 standard trim already contains its larger blade. Match the attachment basis before interpreting the weight gap as ballast or missing equipment.

The two publications also show different travel-reduction refill quantities while sharing the swing-reduction entry. Their common engine and similar excavating front do not make every gearbox capacity common. Identify the compartment and the correct machine sheet before ordering oil for a service.

The Tier IV Final package uses SCR without a DPF

Kobelco's description identifies a diesel oxidation catalyst and selective catalytic reduction, with a DEF tank, on this updated engine package. It expressly says there is no diesel particulate filter. A seller's account of “DPF regeneration” therefore needs clarification against the actual engine and exhaust installation; it does not follow from this brochure's equipment description.

The iNDr dust screen is another component entirely. Kobelco describes a removable, washable intake screen and offset cooling-air ducts that also absorb engine sound. Cleaning that screen addresses its named cooling-air path.

It is not an exhaust-filter service.

The SK140 launch release also describes Independent Travel, while its brochure explains the division of pump supply between travel and the attachment. Record whether that function is selected when comparing simultaneous travel and front movements. A single-function stationary demonstration cannot establish how the selected travel arrangement behaves.
