OEM المعدات التفاصيل

Identify mechanical or AC drive first, then body, wheel position and assembly

785, 789, 793 and 797F use mechanical transmissions, differentials and final drives. 794 AC, 796 AC and 798 AC use alternators, inverter controls and wheel traction motors. Body, frame, suspension, wheel-end and brake configurations also vary by model, serial number, region and project options. Rated payload alone does not establish interchangeability.

Body floor, front wall, sides, tail edge and flying-rock protection

Official Cat images identify models and installation areas. Generic part images identify categories and do not establish Cat OEM interchangeability. Material options require confirmation against body drawings, ore conditions, wear maps and failure modes.

Body floor liners

Dump Body Floor Liners

Fit loading-impact zones and principal sliding paths during dumping, resisting large-rock impact, compression and abrasion. The image identifies a category, not Cat OEM interchangeability. Check complete model, body type, segment drawing, thickness, holes and connections.

Material Selection:Start with quenched and tempered wear plate. Under heavy impact and large rock sizes, check toughness, weldability, backing support, thickness and total liner mass together.

Quenched and Tempered Wear Plate Bimetallic composite wear plate

View body floor liners →

Body front-wall liners

Body Front Wall Liners

Protect the front wall and floor transition from initial loading impact, accumulated-material pressure and repeated sliding. Check wall angle, stiffeners, liner limits, overlap direction and bolted or welded structure.

Material Selection:Strong, tough wear plate is the principal option. Determine material and thickness from drop height, rock size, effective payload and structural fatigue limits.

Quenched and Tempered Wear Plate

Body side and corner liners

Body Side & Corner Liners

Cover lower sidewalls, floor corners and local sliding-wear paths. The image identifies a category. Left/right positions, plate numbers, edge clearances, overlap and welding limits must match actual body drawings.

Material Selection:Sidewalls require wear resistance, formability and weight control. Confirm material, thickness and coverage from wear maps rather than copying floor-liner configurations.

Quenched and Tempered Wear Plate

Tail-edge and discharge-edge wear parts

Rear Discharge Wear Liners

Tail edges, rear floor sections and discharge edges face concentrated sliding wear and edge impact during tipping. Check structure, wear-band width, segments, weld orientation and interference through hoisting motion.

Material Selection:Start with quenched and tempered wear plate. Assess composite protection in severe sliding-wear zones after confirming impact, welding, weight and maintenance conditions.

Rock-box liners and body guards

Rock Box Liners & Body Protection

Some applications use rock-box liners, canopy rock guards or local replaceable protection. Presence and scope vary with body design. Confirm project body drawings, material density and loading equipment.

Material Selection:Assess wear plate for flat guards. Complex load-bearing parts require structural steel, cast-steel nodes, welding and non-destructive testing checks; hardness alone is insufficient.

Mudguards, rock guards and rock ejectors

Mud Guards, Rock Deflectors & Ejectors

Fit around tyres, frames and platforms to block mud, flying rock and debris and protect pipes, suspension and adjacent tyres. The image identifies a category. Check left/right position, tyre specification, brackets and movement envelope.

Material Selection:Confirm rigid brackets by structural strength and corrosion resistance. Check impact-exposed replaceable plates against wear plate or original elastic materials.

Core frame, suspension, hydraulic, mechanical-drive, AC-drive and wheel-end spares

Group parts by load-bearing structure, drive type and assembly. Do not mix mechanical and AC drive systems. Safety- and fatigue-critical parts require traceable materials, heat treatment, dimensions, non-destructive testing and installed identification.

Frames, cast-steel nodes and body hinges

Frame, Cast Nodes & Body Pivots

Frame rails, crossmembers, cast-steel nodes, body hinge brackets and lugs withstand cyclic bending and torsion. Repair or replacement requires complete model, serial number, base material, welding limits, pin-bore coaxiality and inspection requirements.

Material Selection:Frame plate, heavy cast-steel nodes, pins and wear protection follow different material and manufacturing routes. A wear-resistant grade cannot replace structural strength and fatigue checks.

Mechanical transmissions, differentials and final drives

Mechanical Transmission & Final Drives

785, 789, 793 and 797F use mechanical drives with transmissions, shafts, differentials, final drives, gear shafts and housings. Confirm model, serial number, assembly number, tooth count, module, splines and ratio.

Material Selection:Confirm gears, shafts and splines by heavy-duty drive alloy steel with carburising or quench-and-temper treatment. Large housings and supports require casting-quality, bore-fit and non-destructive testing checks.

AC alternators, inverter controls and wheel motors

AC Alternator, Inverter & Wheel Motors

Diesels in 794 AC, 796 AC and 798 AC drive alternators that feed rear-wheel traction motors through inverter controls. Check model, system version, alternator and motor nameplates, cooling, interfaces and reduction ratio.

Material Selection:Prioritise original electrical parameters and mechanical interfaces for electric-drive assemblies. Then confirm wheel-end gears, shafts and supports by alloy steel, heat treatment, bearing and seal requirements.

Suspension cylinders, steering and body-hoist hydraulics

Suspension, Steering & Hoist Hydraulics

Suspension, steering and hoist systems include barrels, rods, guides, seals, valves and piping. Provide position, bore, rod diameter, stroke, interfaces, pressure and leakage or scoring records.

Material Selection:Confirm rods and loaded shafts by quench-and-temper treatment and surface strengthening. Select seals by pressure, temperature, speed, media and contamination. Model alone does not establish interchangeability.

Brakes, hubs, bearings and seals

Brakes, Hubs, Bearings & الموانع

Oil-cooled wet multiple-disc brakes, hubs, bearings, seals and rim interfaces are safety-critical assemblies. Distinguish mechanical and AC drive, front/rear position, brake type, tyre/rim specification and complete installed version.

Material Selection:Confirm brake friction pairs, gear-shaft parts, bearings and seals separately against original designs and traceable technical requirements. General material descriptions cannot replace safety checks.

Alloy steel for hubs and shafts Sliding supports and bearing copper alloys Wheel-end seal materials

View bearings, bushings and supports →

Body-hoist pivots, pins and bushings

Body Hoist Pivots, Pins & Bushings

Rear body hinges and hoist-cylinder pivots carry heavy oscillating loads and impact through pins, bushings, thrust parts, seals and lugs. Check diameter, length, lubrication holes, locks, bore dimensions and wear.

Material Selection:Confirm pins by quenched and tempered alloy steel and surface strengthening, and bushings by bearing copper alloys, steel-backed composites or original construction. Check fits, lubrication and bore repair together.

Can mechanical-drive and AC-drive Cat mining truck spares be mixed?

No. 785, 789, 793 and 797F use mechanical transmissions, differentials and final drives. 794 AC, 796 AC and 798 AC use alternators, inverter controls and wheel traction motors. Confirm complete model, serial number, drive type and assembly first.

Is the model 797F or 798 AC enough to identify body liners?

No. Provide serial number, body type, liner configuration and segment drawings, position, thickness, holes or welding limits, used-part photos, current material, rock size and abrasive conditions.

How can truck parts be identified without a Caterpillar OEM drawing number?

Start with machine nameplate, complete model and serial number, position, assembly nameplate, photos, key dimensions and material tests. Assess whether catalogues, drawing searches or a physical survey can provide technical confirmation.
