Part Number

128-9654 (1289654)

Product Type

Wear Plate - Short Type (OEM replaceable sacrificial wear component)

Primary Application

Caterpillar 120 Series Motor Graders, Caterpillar 12 Series Motor Graders

Core Material

Cat-specified high-strength low-alloy steel with hardfacing alloy welding layer (Cr-Mn-Mo grade)

Surface Hardness

Hardfaced layer: HRC 55-62 (ultra-high wear resistance); Base material: HRC 28-35 (high structural toughness)

Processing Technology

CNC precision cutting → shot blasting → hardfacing treatment → surface grinding → anti-rust coating

Key Dimensional Tolerance

Thickness: ±0.05mm; Flatness: ≤0.03mm/m; Mounting hole position: ±0.1mm (ensures exact fit with fasteners)

Typical Dimensions (Short Type)

Customized short-length profile for compact installation (exact length/width/thickness consult Caterpillar Official Parts Catalog, matched to 120/12 grader’s designated contact points)

Mounting Method

Bolted fixed (matches Cat’s original high-strength fasteners for motor graders; no welding required)

Operating Temperature Range

-40°C to +150°C (-40°F to +302°F) – stable performance under extreme construction site temperature changes

Wear Resistance

Exceeds Cat’s heavy-duty grader application requirements, wear rate far lower than ordinary carbon steel plates

Impact Load Capacity

Withstands dynamic impact loads up to 50 kN (compatible with grading work on gravel/rocky ground)

Installation Tool

Standard hand tools (socket set, wrench) – no special customized equipment required

Net Weight

Approx. 0.2–1.0 kg (0.44–2.20 lbs) per unit (varies by exact short-type dimensional design for different installation positions)
