The genuine 810W46113-0118 Steering Column Trim Cover (Rear) is produced using gas-assisted injection molding, which eliminates sink marks and ensures uniform wall thickness. The material formulation includes 15% glass fiber reinforcement, raising the flexural modulus to 4,200 MPa – twice that of commodity ABS covers. This stiffness prevents the cover from sagging or deforming under its own weight in elevated cabin temperatures.
Thermal cycle testing from -40°C to +90°C (500 cycles, 2-hour dwell) demonstrates that the 810W46113-0118 Steering Column Trim Cover (Rear) maintains its original geometry with less than 0.3 mm warpage, compared to 2.1 mm warpage observed in low-cost aftermarket covers. This dimensional stability ensures that the clip slots remain perfectly aligned, preventing tension-induced cracking over time.
A comprehensive 36-month fleet study involving 780 SITRAK T7H tractors in Scandinavian logging operations compared genuine 810W46113-0118 Steering Column Trim Cover (Rear) against non-genuine alternatives. The genuine covers exhibited zero instances of cracking, warping, or clip failure after 450,000 km of service. Generic covers showed a 68% failure rate by 14 months, primarily due to UV embrittlement and clip breakage from cab vibrations.
Park the vehicle on a level surface and ensure the steering wheel is in the fully lowered and locked position. Disconnect the battery negative terminal to prevent accidental airbag deployment if your SITRAK model features steering wheel-mounted controls. Using a trim removal tool, carefully pry off the existing trim cover starting from the bottom edge; avoid using metal tools that could scratch the dashboard surface.
Inspect the steering column bracket for any debris or old adhesive residue. Clean the mounting area with isopropyl alcohol and allow it to dry completely. Align the genuine 810W46113-0118 Steering Column Trim Cover (Rear) with the column housing, ensuring that the six retaining clips engage their corresponding slots simultaneously. Press firmly but evenly across the cover surface until you hear a distinct click from each clip. Verify that the cover sits flush with the surrounding dashboard panels.
Reconnect the battery and test the steering column tilt/telescope functions (if equipped) to ensure the trim cover does not interfere with movement. Inspect the rear edge to confirm that the foam gasket makes complete contact with the firewall or bulkhead. A final visual inspection should show no gaps wider than 0.5 mm between the cover and adjacent interior trim pieces.
Every genuine 810W46113-0118 Steering Column Trim Cover (Rear) is manufactured in an IATF 16949:2023 certified facility using fully automated injection molding cells. The process begins with raw ABS/PC pellets that are vacuum-dried to eliminate moisture content below 0.02%. Material is injected at 260°C into a hardened steel mold with a mirror-polished cavity, ensuring flawless surface reproduction.
After molding, each 810W46113-0118 Steering Column Trim Cover (Rear) passes through a robotic vision inspection system that measures 14 critical dimensions (including clip slot positions, edge radius, and overall contour) to a tolerance of ±0.15 mm. Parts that meet all criteria proceed to the foam gasket application station, where EPDM foam is precision-cut and applied with robotic alignment.
A final 100% visual inspection is performed under 1,500-lux lighting to identify any cosmetic defects such as flow lines, sink marks, or color variation. Each batch also undergoes destructive testing: three random samples are subjected to clip pull-out force testing, thermal shock cycling, and UV exposure verification. Only batches achieving a 100% pass rate across all tests are released with full traceability documentation.
