H2: Why Choose the 17A-27-11151 HUP KOMATSU Hub?

Durability in Harsh Conditions

This hub is built to survive the toughest working environments. Crafted from robust alloy steel, it’s heat-treated and precision-machined to resist wear, shock, and fatigue under high loads, typical of heavy-duty dozer operations.

Precision Execution

Each piece is machined to tight tolerances so that bolt holes, mounting faces, and hub bores align perfectly , guaranteeing seamless integration into your final drive assembly without rework or fit issues.

Compatibility & Versatility

The 17A2711151 (also listed as 17A-27-11151 HUP KOMATSU) hub is purpose-built for Komatsu final drive / sprocket hub assemblies. It fits both left-hand (L.H.) and right-hand (R.H.) orientations in certain models, making it a flexible choice for repair shops and parts inventories.

Cost-Effective OEM Alternative

While not “genuine,” we maintain strict quality control to deliver parts that match or exceed original specifications. You save cost without compromising function , and 3GEN Export backs this with reliable delivery and support.

H2: Compatible Komatsu Models

According to available parts catalogs, 17A-27-11151 is used in:

• Komatsu D155AX-5, both left and right final drive hub assemblies

• Komatsu D155AX-5 S/N 70001-UP, for both L.H. and R.H. final drive configurations

• Komatsu D155AX-5 series (as per hub listings)

(If you have access to your Komatsu parts manual or EPC, you can cross-check additional models.)

Because it is part of the final drive / sprocket hub and carrier assembly, this hub is critical in transferring torque to the track sprocket.

H2: Technical Specifications & Details

Below is a speculative but informed breakdown based on catalog listings and typical hub design practices. (Always verify with your engineering team.)

Because the hub is part of a rotating, load-bearing subsystem, its geometry, concentricity, and material integrity are crucial. Any deviation can lead to accelerated wear, noise, or failure in the final drive system.

H2: Detailed Description & Benefits (In Use)

Structural Integrity Under Load

When your dozer is pushing heavy loads, the final drive hub must transmit torque from the planetary gears to the sprocket reliably. The 17A-27-11151 is engineered with internal ribs, filleted transitions, and stress-relief features to prevent fatigue cracks and deformation.

Heat & Friction Resilience

Surface hardness and case-hardening are optimized so that the hub maintains its integrity even under high friction, heat, and cyclic loading. This reduces the risk of wear at contact surfaces, keyways, or mating flanges.

Reduced Maintenance & Downtime

Because of precise machining and strict quality standards, this hub fits directly into the assembly without the need for rework, alignment tweaks, or shimming in most cases , saving you labor and machine downtime.

Interchangeable & Easy Inventory

We provide the hub under both part number variants (with and without dashes) to ensure that customers searching “17A2711151” or “17A-27-11151 HUP KOMATSU” land on the same page. This improves your site SEO reach and reduces confusion for buyers.

H3: Installation Tips & Best Practices

• Always clean mating surfaces thoroughly , remove debris, scale, rust, or old gasket residues.

• Use the proper torque sequence for hub bolts, applying progressive tightening to avoid distortion.

• Check alignment of the hub face relative to the carrier and sprocket mounting surfaces.

• If the hub has a keyway or spline, ensure the mating shaft and key are within tolerance and clean.

• Use new fasteners per Komatsu torque specs , do not reuse old bolts susceptible to fatigue.

• After two to three hours of operation, re-check bolt torque and alignment.
