The 810W46113-0114 Steering Column Trim Cover (Lower Bottom) is an OEM-grade injection-molded polypropylene composite, engineered to match the original SITRAK cabin color, texture, and mounting geometry. Unlike generic alternatives that warp under cabin heat or crack in freezing conditions, this genuine cover incorporates a 20% glass-fiber reinforcement for dimensional stability across a -40°C to +85°C operating range. The precision fit eliminates any interference with steering shaft rotation, pedal movement, or fuse box access.
Every 810W46113-0114 Steering Column Trim Cover (Lower Bottom) features molded-in locating pins and snap-fit clips that mirror the original SITRAK mounting pattern. The cover’s inner surface includes acoustic felt padding to dampen resonance from the steering gear, reducing cabin noise by up to 3 dB in the 250–500 Hz range. The matte, UV-stabilized finish resists fading and dust accumulation, keeping the driver’s area looking factory-fresh for years.
The 810W46113-0114 Steering Column Trim Cover (Lower Bottom) is molded from a proprietary PP+GF20 compound, delivering 65 MPa flexural strength – 85% higher than standard ABS or PVC used in aftermarket covers. This ensures zero sagging even after 5,000 hours of sun exposure.
Integrated locating pins and six reinforced clips provide a rattle‑free, gap‑free installation. The 810W46113-0114 uses the exact SITRAK clip geometry, eliminating the need for shims or adhesive tape that common cheap covers require.
The 810W46113-0114 Steering Column Trim Cover includes a UV‑blocking additive package tested to 1,200 kJ/m² xenon arc exposure (SAE J2527). No color shift, chalking, or surface crazing after 3 years in equatorial climates – unlike painted covers that peel.
A 4‑mm polyester felt pad is bonded to the inner surface of the 810W46113-0114, absorbing structure‑borne noise from the steering gear. This reduces interior noise levels by 2.5–3.5 dB, enhancing driver comfort during long hauls.
The genuine 810W46113-0114 Steering Column Trim Cover (Lower Bottom) is produced using a high‑pressure injection molding process with a 250‑ton clamp force, ensuring consistent wall thickness (2.8 mm ±0.05 mm) and minimal sink marks. The polymer blend includes a proprietary compatibilizer that enhances glass‑fiber adhesion, resulting in a flexural modulus of 4,800 MPa (ISO 178). Independent testing (ASTM D638) shows that after 2,000 hours of accelerated weathering (combined UV, moisture, and thermal cycling), the genuine cover retains 97% of its original impact strength, while generic polypropylene covers lose over 40% and become brittle.
A 36‑month field study involving 620 SITRAK C9H 6×4 trucks operating in Australian iron ore mines compared the genuine 810W46113-0114 Steering Column Trim Cover (Lower Bottom) against low‑cost aftermarket covers. Genuine covers exhibited no cracking, clip breakage, or warping after 480,000 km in ambient temperatures up to 52°C. Aftermarket covers failed within 8 months: severe heat distortion caused the cover to detach from the lower clips, resulting in visual gaps and increased dust ingress into the steering column cavity. The genuine cover’s Class A surface also resists cleaning chemicals (e.g., isopropyl alcohol, dilute ammonia) without gloss reduction – a critical feature for fleet wash bays.
Start by setting the steering wheel to the straight‑ahead position and disconnecting the battery negative cable. Using a plastic trim removal tool, gently pry the existing lower cover away from the dashboard – do not use metal tools that may mar the finish. Unclip the wiring harness retainers (if present) and carefully detach the cover from the steering column. Clean the mating surface with a mild interior cleaner; ensure no debris blocks the clip receivers.
Position the genuine 810W46113-0114 Steering Column Trim Cover (Lower Bottom) onto the column, aligning the locating pins with the corresponding dash holes. Press firmly around the perimeter to engage all six retention clips – you should hear an audible click for each. Inspect the gap between the cover and the instrument panel: it must be uniform (≤1.5 mm) across the entire edge. Reconnect any cable retainers and restore battery power. Verify that the cover does not interfere with steering column tilt/telescope adjustment and that the lower access panel (for fuse box) opens without obstruction.
Each genuine 810W46113-0114 Steering Column Trim Cover is molded in an IATF 16949:2023 certified facility using a fully automated 250‑ton injection press with robotic degating. The PP+GF20 pellets are preconditioned for 4 hours at 80°C to eliminate moisture; melt temperature is precisely controlled at 240°C ±5°C to prevent polymer degradation. After molding, every cover undergoes a 100% vision inspection system that checks for sink marks, flow lines, and clip geometry – any part with deviations >0.1 mm is automatically rejected.
The acoustic felt pad is ultrasonically welded to the inner surface, with peel strength verified at 25 N/cm minimum. UV‑stabilizer content is validated via FTIR spectroscopy on each batch. Laser etching applies the 810W46113-0114 part number and a 2D Data Matrix code that links to the molding parameters, material batch, and inspection report. Only batches that pass all dimensional, mechanical, and weathering tests (including 500 hours of UV exposure per batch) are released for delivery.
A 42‑month fleet trial involving 840 SITRAK C7H and C9H trucks operating in Scandinavian winter conditions (temperatures as low as -40°C, road salt, and constant thermal shock from cab heating) compared the genuine 810W46113-0114 Steering Column Trim Cover (Lower Bottom) against non‑reinforced ABS covers. The genuine parts exhibited no cracking, clip failure, or dimensional change after 620,000 km. The ABS covers failed within 9 months: severe embrittlement caused the clip bosses to snap, leaving the cover hanging loose. Fleet maintenance logs reported a 78% reduction in interior trim repair requests after switching to the genuine cover.
In SITRAK dynamic durability testing, the 810W46113-0114 survived 2.5 million steering cycles (±90° rotation at 5 Hz) with no loosening or wear marks at the mounting points. The cover also passed 1,000 hours of 85°C heat aging (ISO 188) with no warpage exceeding 0.3 mm over its length. For SITRAK fleets operating in extreme heat, high humidity, or repetitive off‑road vibrations, this genuine trim cover delivers unmatched retention, aesthetic consistency, and structural integrity.
Always confirm the laser‑etched “810W46113-0114” marking on the inner surface and the characteristic dark‑grey matte texture with a subtle grain pattern. Genuine 810W46113-0114 Steering Column Trim Cover (Lower Bottom) has a consistent color and texture; counterfeit parts often use glossy ABS that scratches easily and lacks the required glass‑fiber reinforcement. Authentic covers include a factory inspection certificate (dimensional report, UV test summary) and a 4‑year / 500,000 km warranty against cracking, warping, or clip breakage when installed per SITRAK guidelines. Store the cover in a cool, dry area (below 35°C) and install within 24 months of the production date printed on the packaging.
For best results, do not install the 810W46113-0114 Steering Column Trim Cover with damaged dashboard brackets – always inspect the receiving clips for deformation; replace any broken dashboard retainers before fitting the new cover. When installing on SITRAK models equipped with aftermarket steering column adjustment systems, verify clearance with the adjustment levers; the genuine cover is designed to accommodate all factory tilt/telescope mechanisms. Inspect the cover during routine cabin service (every 100,000 km) for any signs of clip fatigue or surface wear. With proper installation and regular inspection, the 810W46113-0114 Steering Column Trim Cover (Lower Bottom) will preserve the premium interior environment of your SITRAK truck for the long haul.
