Wheel Reducer Assembly 800345910 / 83513200
This wheel reducer assembly is listed with references 800345910 and 83513200 in the motor grader parts category. The original page described a specific internal gear arrangement and ZL-series loader fitment, but those claims are not supported by the available product record. This revision keeps the verified references and focuses on the physical evidence needed for correct matching.
Before ordering: Send the complete machine model and serial number, photographs of both sides of the reducer, every identification mark, and clear views of the input and wheel-side interfaces.
Do not assume the internal design
A wheel-end reducer can contain different internal layouts, bearing arrangements, splines and sealing systems even when the outside housing looks similar. References 800345910 and 83513200 are the primary catalog clues, while the housing profile, flange pattern, pilot diameters, spline details and overall width help confirm the assembly.

Symptoms that justify inspection
Oil leakage, abnormal wheel-end noise, excessive play, overheating or metallic debris can lead to reducer inspection. These observations do not identify one failed internal part. Bearings, seals, gears, splines and adjacent axle components should be assessed using the service procedure for the exact machine. Record whether the symptom changes with speed, load or travel direction.
Evidence to collect before removal
Photograph identification plates, cast numbers and stamped references before cleaning removes temporary markings.
Record the assembly orientation and each oil fill, level or drain location.
Measure flange diameter, pilot diameter, bolt-hole count and spacing.
Document spline tooth count and dimensions only with suitable tools and procedures.
Inspect the mating hub, axle interface and fasteners for secondary damage.
Preserve oil and debris observations for the technician’s failure analysis.
Installation and commissioning planning
Use lifting support appropriate to the assembly and follow the machine repair instructions. Keep open housings and oil passages protected from dirt. Use the specified seals, lubricant, tightening sequence and fill procedure for the confirmed model. After installation, check oil level, leakage, abnormal temperature and noise during a controlled low-load test.

FAQ
Is this reducer confirmed for a ZL-series wheel loader?
No. The available record places it in Motor grader parts but does not state an exact machine model. Confirm the serial number and original assembly.
Are 800345910 and 83513200 guaranteed equivalents?
They are grouped in this product record. Final supply still requires reference and interface verification.
Can the internal gear design be identified from the exterior?
No. Do not infer the internal arrangement or ratio from housing appearance alone.
What information should I send?
Provide both references, machine model and serial number, installed-location photos, flange and spline views, dimensions, quantity and destination.
Compatibility note: Match the complete assembly to the original machine record and physical interfaces before purchase.
