Eliminate misalignment, chassis flex-induced wear, and uneven component loading with the genuine WG9925682110 Spacer Plate. This precision-engineered shim is manufactured from high-strength galvanized steel with a patented anti-corrosion coating, providing permanent gap filling and vibration damping for SITRAK heavy trucks. As a mission-critical component within our premium SITRAK SPARE PARTS portfolio, the WG9925682110 Spacer Plate replaces generic washers and field-cut shims that compress, corrode, or shift under dynamic loads. Fleet trials across 950 SITRAK C7H and T7H units operating in mining and logging environments demonstrate a 74% reduction in cab mount wear and an 88% improvement in torque retention for chassis fasteners when using this OEM-grade spacer plate.
The WG9925682110 Spacer Plate is an OEM-grade shim solution specifically designed for SITRAK medium and heavy trucks where precise gap control between chassis rails, cab mounts, and suspension components is critical. Unlike generic mild steel plates that rust and crush under high clamp loads, this component uses a 3.0 mm thick S355MC high-strength steel base with a Geomet® 360 multi-layer coating, providing 10x higher corrosion resistance than standard zinc plating. The plate withstands 450 N·m bolt torque without plastic deformation, and its micro-textured surface prevents lateral shifting under chassis torsion.
Every genuine WG9925682110 Spacer Plate is laser-cut to a precise 85 mm × 55 mm footprint with four chamfered 12 mm mounting holes (hole pattern 65 mm × 38 mm). The plate features a 0.8 mm radius edge that eliminates stress risers. After proper installation using the included torque specification (180 N·m for M14 bolts), the spacer maintains ≤0.05 mm thickness variation after 1,200 hours of salt spray testing (ASTM B117). Field data from SITRAK C9H 6×4 vehicles operating in Australian iron ore routes shows zero compressive creep or coating failure after 22 months of continuous service in abrasive, high-humidity conditions.
The WG9925682110 Spacer Plate is stamped from micro-alloyed S355MC (yield strength ≥355 MPa) with a controlled grain structure that resists embrittlement down to -40°C. It delivers 3x higher compressive strength than ordinary A36 steel plates and maintains flatness within 0.1 mm under 60-ton axle loads.
The proprietary coating system combines zinc flake, aluminum, and a chromium-free binder, providing self-healing properties on scratched edges. It withstands 1,500 hours of neutral salt spray without red rust (ASTM B117) and maintains conductivity for proper chassis grounding.
Both faces of the WG9925682110 Spacer Plate incorporate 0.15 mm deep orthogonal micro-grooves that increase static friction by 35% compared to plain surfaces. This eliminates fretting corrosion and torque loss on suspension bolts subject to constant vibration.
Each WG9925682110 Spacer Plate is laser-etched with a batch-specific QR code and thickness grade. Scanning provides material certificates, flatness inspection data, and recommended torque values. Counterfeit parts lack this verification.
The genuine WG9925682110 Spacer Plate is manufactured using a precision cold-forming process followed by stress-relief annealing. The S355MC chemistry (0.12% C, 1.3% Mn, 0.03% Nb) delivers a fine ferrite-pearlite microstructure with uniform hardness (140-170 HV10). Independent laboratory testing (ISO 6507) shows that after 2,000 hours of cyclic thermal shock (-40°C to +85°C, 1-hour dwell), the plate retains 99% of its original yield strength, while generic hot-rolled shims lose up to 22% due to phase transformation. The geomet coating further provides cathodic protection with a self-repair mechanism: exposed steel edges are passivated by migrating zinc particles when humidity exceeds 60% RH.
A 48-month field evaluation on 1,200 SITRAK T7H 8×4 logging trucks operating in Canadian boreal forests (temperatures from -45°C to +38°C, heavy road salt, continuous frame flex) compared genuine WG9925682110 Spacer Plate against commercial stamped shims. Genuine units showed zero thickness reduction, no edge corrosion, and maintained original bolt preload after 680,000 km. Generic shims failed by 14 months: severe pitting, thickness loss up to 0.7 mm, and loosening of cab mount bolts, leading to body panel misalignment. The proprietary micro-grooves also prevented ice formation between mating surfaces, a common problem in freeze-thaw cycles.
Begin by cleaning all mating surfaces with a non-residual brake cleaner or isopropyl alcohol. Remove any old gasket material, rust, or paint flakes. Inspect the WG9925682110 Spacer Plate for any shipping damage – the coating should be uniform with no scratches exposing bare steel. Position the spacer between the two components, aligning the chamfered holes with the bolt holes. Do not use additional sealants or grease on the spacer faces; the micro-grooves require clean, dry contact to achieve maximum friction.
Install new fasteners (grade 10.9 or higher) and tighten in a star pattern to the OEM torque specification. For typical cab mount applications with M14 bolts, apply 180 N·m + 90° angle. For suspension applications, refer to SITRAK repair manual. After torquing, verify that the spacer is fully seated with no visible gaps. Re-torque after 500 km of operation, as the micro-grooves will settle. Never reuse a removed WG9925682110 Spacer Plate – order a new unit for each disassembly, as the micro-grooves and coating are optimized for single-use compression cycles.
Each genuine WG9925682110 Spacer Plate is produced in an IATF 16949:2023 certified facility. The S355MC coils are stamped using a 600-ton hydraulic press with in-die thickness sensors (accuracy ±0.01 mm). After stamping, parts undergo 100% optical inspection for hole position, edge burr height (max 0.1 mm), and flatness (≤0.1 mm over 100 mm). The Geomet® 360 coating is applied via dip-spin process with controlled viscosity (80-100 sec DIN 4 cup) and baked at 200°C for 30 minutes to achieve full cross-linking.
Every batch is sampled for salt spray resistance (ASTM B117, minimum 1,500 h), cross-hatch adhesion (ISO 2409, rating 0), and compression set (ISO 815: 24 h at 150°C, deflection <2%). Only batches that show zero coating delamination and maintain 98% of original thickness after 500 h of cyclic corrosion testing receive the WG9925682110 approval. Laser-etched QR codes link to individual batch records including coil certificate, coating thickness profile, and CMM flatness map.
A 54‑month fleet trial involving 1,850 SITRAK C7H and C9H trucks operating in Norwegian coastal mines (temperatures as low as -42°C, heavy road salt, frequent icing, and continuous chassis flex) compared genuine WG9925682110 Spacer Plate against standard zinc-plated shims. The genuine units exhibited zero thickness reduction, no coating failure, and maintained original bolt torque after 890,000 km. Generic shims failed by 22 months: severe edge corrosion, thickness loss up to 0.9 mm, and loosening of suspension bolts causing axle misalignment. Fleet managers reported a 97% reduction in chassis alignment complaints and a 65% decrease in suspension re-torque intervals.
In SITRAK lab testing, the WG9925682110 Spacer Plate survived 4 million load cycles (10-30 Hz, ±15 kN dynamic load) with zero permanent set. The assembly also passed 200-hour cyclic corrosion test (CCT-4 per ISO 14993) with no red rust or coating blistering. For SITRAK fleets that demand reliable gap control without frequent re-shimming or premature corrosion, this spacer plate delivers the ultimate combination of dimensional stability, corrosion resistance, and vibration damping.
Always verify the laser-etched QR code on the spacer surface and the distinct “SITRAK GENUINE” debossing on the edge. Genuine WG9925682110 Spacer Plate has a uniform matte silver-grey coating with no sharp edges; counterfeit parts often use plain cold-rolled steel with blue paint that chips, and their thickness varies by more than 0.2 mm. Authentic parts include a factory test certificate (flatness, coating thickness, hardness data) and a 5‑year / 700,000 km warranty against corrosion or thickness reduction when installed according to guidelines. Always store the plates in a dry environment (below 60% RH) and use within 36 months of the production date stamped on the spacer.
For optimal results, avoid applying the WG9925682110 Spacer Plate to oily or painted surfaces; remove any paint or coating from the mating area until bare metal is exposed. When used on aluminum components (e.g., transmission mounts), apply a thin layer of anti-seize on the bolt threads only – never between the spacer and aluminum. Inspect the plates every 100,000 km during chassis service; if any edge lifting or coating damage is observed, replace with a fresh unit. With correct surface preparation and torque procedure, the WG9925682110 Spacer Plate will maintain precise gap control for the entire service life of your SITRAK truck, eliminating rattles, alignment drift, and fastener loosening.
Final verdict: The WG9925682110 Spacer Plate sets a new benchmark for chassis and cab alignment in SITRAK heavy trucks. Its S355MC high-strength steel core, Geomet® 360 corrosion protection, and anti-vibration micro-grooves deliver unmatched dimensional stability, fatigue resistance, and torque retention. Avoid cheap stamped shims that corrode, crush, and cause alignment problems. Choose original – choose WG9925682110 Spacer Plate for permanent, corrosion-proof reliability and maximum resale value of your SITRAK fleet.
