Upon delivery, the gearbox arrives in a sturdy, wooden-crated package designed to protect the heavy component during shipping—a good first sign for a part of this nature. Inside the crate, you will find:
Notably, installation hardware (bolts, seals for the machine side) is typically not included, as these are usually reused from the original assembly or must be purchased separately if damaged. The build quality upon visual and tactile inspection is impressive; the casting is clean, with no visible porosity, and the machined surfaces are smooth. The input shaft rotates smoothly with the expected resistance from internal gearing. This initial quality check is crucial when deciding if the CAT 167-4049 gearbox pros cons balance favors a purchase.

Safety First: Park the excavator on level, solid ground. Lower the bucket to the ground, engage the parking brake, and shut down the engine. Relieve all hydraulic pressure by moving the control levers through all functions. Disconnect the battery.
Once physically installed, the system requires proper priming and bleeding. Fill the hydraulic tank with the correct fluid type and grade specified for your CAT 3046. Before starting the engine, it is advisable to slightly loosen the hydraulic return line connection at the tank to allow air to escape during the initial bleed cycle. Start the engine and run it at low idle. Slowly operate the travel controls in a gentle, forward-and-reverse motion (with the machine still off the ground if possible) to circulate fluid and purge air from the motor and lines. Tighten any connections once the air bubbles cease. This careful first-time procedure is a key part of ensuring a successful CAT 3046 excavator gearbox replacement.
After installation and bleeding, the gearbox functions identically to the original. The integrated motor responds to the operator’s travel pedal or joystick inputs, converting hydraulic power into mechanical rotation, which is then reduced through the planetary gear sets to drive the sprocket. For daily use, perform a quick visual inspection for leaks around the seal areas before and after each shift. Listen for any unusual noises during travel, such as grinding or whining, which could indicate a problem.
For operators looking to maximize the lifespan of the new unit, avoid “track spinning” on the spot, especially on abrasive surfaces, as this places extreme shock loads on the gears. When traveling on slopes, use controlled, steady speed rather than herky-jerky movements to maintain consistent hydraulic pressure and reduce stress.
Regular maintenance is non-negotiable. Check the gear oil level in the final drive (which this gearbox drives into) according to your machine’s service interval—typically every 250-500 hours. Change the hydraulic fluid and filters at the recommended intervals to keep the fluid clean, as contamination is the enemy of the hydraulic motor. Periodically clean dirt and debris from around the gearbox housing and seals. For a comprehensive maintenance schedule, refer to our hydraulic system care guide.
If you encounter persistent issues after installation, it may be worth reviewing if you made the right choice to buy CAT 3046 travel gearbox from this supplier and contacting their support. For those still in the research phase, you can examine the product details closely on its Amazon product page.

We installed the OKwillBE 167-4049 gearbox on a CAT 317BL with a documented weak travel motor. Our testing spanned three weeks of actual operation on a residential demolition and site grading project, encompassing approximately 120 engine hours. We monitored for performance metrics, reliability, and any signs of premature wear.
In terms of speed and power, the unit restored the excavator’s travel performance to like-new specifications. There was no noticeable lag or hesitation in response. The machine could climb moderate grades and pivot smoothly under load. Most importantly, we observed no fluid leaks from the new unit’s seals throughout the testing period—a critical indicator of manufacturing quality. The operational noise level was consistent with a healthy gearbox, with no grinding or knocking sounds.
The gearbox was tested in varied conditions: traveling over rough, uneven terrain with partial loads, performing precise spotting maneuvers, and sustained travel on flat ground. It handled shock loads from minor track slippage without issue. In muddy conditions, the seal integrity held firm, with no water ingress detected in subsequent oil checks.
The product claims direct compatibility and reliable performance. Our hands-on testing confirmed these claims. It bolted up correctly and functioned as a direct replacement should. While long-term durability over thousands of hours remains to be seen, the initial performance strongly suggests this is a viable alternative, answering the core question of whether the CAT 3046 gearbox worth buying as an aftermarket part.
Weighing these CAT 167-4049 gearbox pros cons is essential for making an informed decision.
When considering a CAT 3046 excavator gearbox replacement, you typically have three main options: a new CAT OEM part, a rebuilt unit from a specialist shop, or a new aftermarket unit like this one from OKwillBE.
| Feature | OKwillBE 167-4049 | CAT OEM New | Local Rebuild Service |
|---|---|---|---|
| Price | ~$9,500 | $20,000+ | $6,000 – $8,000 |
| Warranty | Typically 1 Year (Check Seller) | Full CAT Warranty | 6 Months – 1 Year (Varies) |
| Convenience | Shipped ready-to-install | Shipped ready-to-install | Downtime while unit is rebuilt |
| Core Consideration | None | None | Often requires old core |
| Perceived Risk | New but unproven brand | Lowest risk, highest cost | Depends on rebuilder’s skill |
Choose the OKwillBE 167-4049 if you need a new, ready-to-ship unit faster and cheaper than OEM, you don’t have a reliable local rebuilder, or you want to avoid the uncertainty of a rebuild’s quality. It’s a strong candidate for the best travel gearbox for 317BL owners prioritizing budget and turnaround time.
Stick with a CAT OEM part if your operation is under a stringent warranty or maintenance contract that requires genuine parts. Opt for a reputable local rebuild if you have a trusted shop, want to support local business, and your old housing is in good, rebuildable condition. For a deeper dive into this decision matrix, see our article on choosing excavator replacement parts.
Before you even unbolt the old unit, thoroughly inspect the final drive sprocket and bearings. A worn final drive will destroy a new travel gearbox quickly. Replace companion components if needed.
When installing any new hydraulic component, especially after a failure, consider flushing the related hydraulic circuit. This removes contaminant particles that could damage the new motor.
Don’t skimp on the consumables. Use premium-grade hydraulic fluid and genuine or high-quality aftermarket seals on the machine interface. This small investment protects your larger investment. You can find compatible hydraulic fluids here alongside the gearbox.
For the first 50 hours of operation, avoid running the travel function at full throttle under maximum load. A gentle break-in period allows gears to mate smoothly and seals to seat properly.
Consider sending samples of your final drive gear oil for analysis at regular intervals. This can provide early warning of abnormal wear metals from the gearbox or final drive.
Document the installation date, supplier, part number, and serial number (if any). Track operating hours. This record is invaluable for warranty claims and for evaluating the true lifespan of the part.
