Similar Housings Can Hide Different Gearboxes
A travel reduction gear may match the machine family yet differ in input spline, motor interface, reduction ratio, output housing, sprocket bolt pattern, bearing arrangement, or carrier design.
One model, several final-drive numbers
Production year, serial range, machine configuration, and replacement history change the installed unit. Include the full model and all available numbers.
Gearbox-only and complete-drive quotes look similar
Some listings show a complete final drive; others exclude the travel motor. Confirm exactly what is included before comparing price.
The visible symptom may have another cause
Weak travel, drift, noise, heat, leakage, or one slow track can involve the motor, brake, valve, pump, hose, track tension, sprocket, or undercarriage resistance.
Left and right are assumed identical
Some machines use the same drive on both sides; others have installation or piping differences. State the required side and compare the old assembly.
Parts selected from tooth count alone
Tooth count is useful but not sufficient. Carrier dimensions, shaft interfaces, bearing seats, gear width, and mating components also need checking.
What settles all five risks
Full model, serial, every number, the required side, and clear photos of the complete unit before separating motor and gearbox.
Confirm What Each Quotation Actually Includes
A complete final drive and a bare gearbox can look identical in photos. Get the supply boundary in writing before you compare a single price.
Start With the Information You Have
A complete part number or only a removed final drive: either can open the check. Choose the route that fits your situation.
Travel Reduction Gear, Travel Motor, or Complete Final Drive?
If the supply boundary is unclear, send a photo showing the complete unit before separating the motor and gearbox. The boundary decides what gets quoted.
| Product | Main Contents | Choose This When | Confirm Carefully |
|---|---|---|---|
| Travel reduction gear | Planetary gears, carriers, ring gear, shafts, bearings, seals, output housing; contents vary | The mechanical gearbox is damaged and the travel motor is suitable for reuse | Input interface, ratio, output housing, sprocket mounting |
| Travel motor | Hydraulic motor, brake, valve, and related hydraulic components | Hydraulic or brake-side inspection points to the motor | Model, ports, displacement and configuration, gearbox interface |
| Complete final drive | Matched travel motor and reduction gearbox assembly | Both sections are damaged or an assembled replacement is preferred | Complete number, machine fit, side, ports, sprocket interface |
| Internal gear parts | Selected gears, carriers, shafts, bearings, seals, or housings | A qualified workshop will rebuild the gearbox | Exact internal structure, dimensions, material and process evidence |
Unsure where the damage sits? Describe the symptoms and send photos; we help fix the boundary before anything is quoted.

Travel Gearboxes for Tracked Equipment
This page focuses on planetary travel reduction units that transmit motor input to the track drive. Final confirmation depends on the exact machine and installed assembly.
Mini and compact excavators
Small packaging and integrated components make full-model suffixes and clear photos especially important.
Standard crawler excavators
Common machine families still use several final-drive references. Confirm by assembly number whenever possible.
Large excavators and mining machines
Unit weight, torque, lifting, oil, and packing requirements need extra review. Supply routes may differ from standard products.
Tracked loaders, drills, special carriers
Drives outside standard excavators need application, machine mass, duty, motor, mounting, and output details, not tonnage-based matching.
Check your machine application
Tell us the machine class, mass, and duty. We confirm whether a model-based match or an application review is the right route.
Search by Machine, Drive, or Part Number
Common inquiries involve the machine brands below and other verified applications. Use brand as the first filter, not the final compatibility decision.
Model not listed? Add the full machine model, serial information, complete assembly reference, and old-drive photos, and we run a manual check.
Compare the Actual Supply Scope
New replacement, genuine, and remanufactured are not interchangeable descriptions. Ask every quotation to state condition, source, included components, inspection scope, and warranty terms.
Gearbox-only replacement
When the existing motor has been inspected for reuse. Confirm whether the quoted unit includes output housing, bearings, seals, plug, and mounting parts.
Complete final drive
When both sections need replacement or a matched assembly reduces interface uncertainty. Confirm motor configuration, ports, side, and output mounting.
Internal repair parts
When a qualified workshop can inspect and rebuild the gearbox. Availability depends on the exact internal structure.
Condition options
New replacement, genuine, or remanufactured, each with its own evidence and warranty scope.
| Route | Useful For | Confirm Before Order |
|---|---|---|
| New replacement gearbox | Mechanical assembly replacement | Manufacturer, compatibility basis, included parts, inspection |
| Genuine / original part | Traceability or original supply requirement | Label, packaging, source, supersession, availability |
| Remanufactured drive | New unit unavailable or rebuild economics preferred | Core, replaced parts, test scope, warranty, core return |
| Internal parts | Workshop rebuild | Dimensions, mating parts, material and process records |
Want a recommendation? Send the machine, symptoms, and budget priority, and we compare the routes for your case.

Protect the Replacement From the Original Failure
One slow side does not automatically prove gearbox damage, and a new unit installed into a contaminated system inherits the old problem.
Before deciding what failed
- Check case drain, pressure, and flow where applicable
- Verify brake release and control valve behavior
- Inspect track tension, sprocket and chain condition, and rotation resistance
- Check external leakage, gearbox oil condition, and debris
Before installation
- Compare every interface and dimension with the old unit
- Inspect the travel motor if it will be reused
- Check sprocket wear, track tension, frame alignment, hoses, fittings, and mounting surfaces
- Remove debris and contaminated lubricant from connected areas
- Verify the correct side and installation orientation
During installation and startup
- Follow the service manual for lifting, fastener torque, oil grade and quantity
- Keep hoses clean; bleed and check brakes as instructed
- Begin operation at low load
- Stop if there is abnormal noise, heat, leakage, vibration, or uneven travel
Keep in mind: A replacement gearbox cannot fix hydraulic supply problems, a dragging brake, or a worn undercarriage. Diagnose first, then order.
Check More Than the Old Part Number
For discontinued or poorly documented drives, one historical number can lead to several routes. Keep the old assembly until the replacement has been fully checked; it may be needed for dimensions, comparison, or a return core.
Superseding number
A superseding gearbox or complete-drive number that replaced the historical reference.
Compatible replacement
A replacement confirmed at interface level: input, output, side, ratio, and envelope.
Gearbox-only route
Keep the existing motor after inspection and replace only the mechanical section.
Complete final drive
The matched assembly when separate matching is uncertain or both sections are worn.
Selected internal parts
Gears, carriers, shafts, and bearings for a qualified workshop rebuild.
Remanufactured unit
A rebuilt drive where a verified remanufacturing route exists.
One Repair, Mixed Batch, or Repeat Supply
No MOQ. A single urgent replacement and a scheduled program follow the same rule: exact identification first.
One urgent replacement
Send the exact drive details and destination. Urgent orders move fastest when the identification package is complete.
Workshop and dealer batches
Provide one line per model: part number, machine, side, quantity, condition, and reference photos.
Repeat supply programs
Confirm stable model records, labels, inspection evidence, and packaging references for reordering.
State the Side Before the Quote, Not After the Delivery
Some machines share one drive on both sides; others do not. One line in your inquiry avoids a very heavy return shipment.
Travel Reduction Gears by Machine and Reference
Example references from commonly requested machines. Exact matching, condition, availability, and lead time are confirmed before quotation.

Confirm Identification Before General Inspection
A complete final drive, a gearbox-only assembly, a remanufactured unit, and an internal gear each need different evidence. Ask which checks apply to the quoted product.
- Product photos and number and label check
- Visual housing inspection
- Agreed interface measurements
- Rotation or assembly checks
- Oil and seal checks where applicable
- Quantity and packing records
Photos are placeholders; replace with real inspection evidence tied to actual orders.
A More Traceable Way to Match a Travel Gearbox
Each claim below is a step you can verify inside the process on this page.
The boundary is checked before the quote
- Assembly-boundary checking: gearbox, motor, complete drive, and parts are separated before quotation
- Multiple identification routes: numbers, machine details, photos, interfaces, and dimensions all count
Repair routes are compared honestly
- Repair-aware options: gearbox-only and internal-parts routes checked when appropriate
- Order-specific description: condition, scope, reference, and evidence stated for the proposed product
Procurement and export stay flexible
- Flexible procurement: one replacement, mixed lists, and repeat model inquiries handled the same way
- Export preparation: protection, labels, cases, and shipment references coordinated with the order
Restrain the Weight and Protect Every Interface
Dense, heavy assemblies punish weak packing. Tell us about fumigation-compliant wood, consolidation, lifting marks, label format, or destination requirements before shipment.
Interface protection
Splines, ports, mounting faces, output housing, and threads capped and protected.
Moisture barrier
Barrier wrapping matched to the shipment route and storage time.
Internal blocking
Stable blocking keeps the unit from shifting inside the case.
Reinforced case
Pallet or wooden case selected for the unit weight.
Product and package labels
Product, quantity, and package labels mapped to the packing list.
Lifting marks
Weight and lifting marks where destination handling needs them.
Compliant wood
Fumigation-compliant wood on request for regulated destinations.
Shipment references
Case, order, and shipment references kept consistent for receiving.
Photos are placeholders; replace with your real packing sequence.
Keep the Installation and Operating Evidence
Warranty terms depend on the quoted condition and the order agreement. Complete records keep any claim short.
Confirm before ordering
- Period, scope, and exclusions for the quoted condition
- Required evidence and the claim procedure
- What the coverage assumes about installation and oil
- Whether inspection or a return core is part of the process
If a problem occurs
- Stop operation when further use could increase damage
- Send the order number, machine, installation date, and operating hours
- Provide oil information, photos and video, and the symptom description
- Add pressure or drain findings where available
- Include inspection results for the motor, brake, sprocket, track, and connected system; do not disassemble unless the agreed process requests it
Replacement or repair is proposed based on the reviewed evidence and the agreed terms.
Send the Drive Details You Have
Start with a part number or several clear photos. We will tell you which information is still needed before a product can be proposed.
Boundary first, then identification, then a quote
- We first review the product boundary and identification details
- We request only the missing measurements or photos
- Quotation follows once the proposed configuration is clear
- Reply within 24 hours, usually much faster

Travel Reduction Gear Questions
The questions buyers ask most before ordering a travel gearbox or final drive.
01Is a travel reduction gear the same as a final drive?
The travel reduction gear is the mechanical planetary gearbox. Final drive often refers to the complete motor-and-gearbox assembly, but supplier naming varies. Confirm what the quotation includes.
02Can I buy the gearbox without the travel motor?
Possibly, when the model is available separately and the existing motor and interface are suitable for reuse. Send both motor and gearbox references.
03Is the machine model enough to identify the drive?
Not always. Some models use multiple drive configurations. Add the serial number, assembly number, motor model, side, and photos.
04What if the number is unreadable?
Send complete-unit photos, casting marks, input interface, output housing, sprocket bolt pattern, pilot, and dimensions.
05Can left and right final drives be interchanged?
Some machines use identical units; others have orientation or piping differences. Confirm the machine and installed configuration before ordering.
06Can you identify internal gears from tooth count?
Tooth count is only one input. Gear width, bore, shaft, carrier, bearing, stage, and mating parts also need comparison.
07Does one slow track prove the gearbox is damaged?
No. Hydraulic supply, motor leakage, brake release, valves, track tension, sprocket, and mechanical resistance should also be checked.
08Should I choose a gearbox or complete final drive?
Choose after inspecting both sections. Gearbox-only may suit a reusable motor; a complete drive reduces uncertainty when both sections are damaged.
09What must be checked before installation?
Compare interfaces, inspect connected components, clean contamination, verify oil and orientation, and follow the machine service procedure.
10What is needed for a quotation?
Send machine details, part numbers, scope, side, quantity, destination, condition preference, and clear photos.
Question not covered? Send it with your machine model and Jeason will answer both at once.
