Buyers should check an excavator travel motor by confirming the machine model, old unit photos, flange, bolt pattern, shaft or spline, hydraulic port layout, rotation, condition grade, diagnosis evidence and export packing before ordering from China.
This guide sits between the final drive guide, swing motor guide, swing motor checklist and fitment checklist.
Quick answer: what proof matters for an excavator travel motor quote?
An excavator travel motor quote should compare the exact old unit with the replacement option. Buyers should send machine model, old unit photos, flange face, bolt pattern, shaft or spline, hydraulic port layout, rotation direction, leakage symptoms and part number if visible. PRIMA can compare OEM-type, aftermarket, used and rebuilt options, but the quote should stay conditional until fitment evidence is complete. Export packing should protect the shaft, ports, flange and heavy housing with final photos before shipment.
Buyer Summary
- This page is for buyers replacing travel motors, final drive assemblies or hydraulic drive components.
- Flange, bolt pattern, shaft and port layout matter more than a broad model name.
- Weak travel symptoms can come from more than the travel motor.
- Packing should protect precision surfaces during export.
Which old-unit photos are needed first?
The old travel motor should be documented before price comparison.
Buyers should send wide photos and close-ups of the flange, bolt pattern, shaft, spline, ports, housing and visible numbers. If the unit is still installed, photos from the track frame can still narrow the match.
Model names alone are not enough because the same machine family can use different hydraulic drive layouts. PRIMA should explain the evidence used for matching.
| Fitment point | Evidence | Risk controlled |
|---|---|---|
| Flange | Face and bolt pattern | Cannot mount |
| Shaft/spline | End photo and measurement | Cannot couple |
| Port layout | Hose side photo | Connection mismatch |
How is travel motor diagnosis different from final drive diagnosis?
Weak travel can involve several systems.
Travel weakness can be caused by final drive gear wear, travel motor leakage, hydraulic pump flow, control valve, hoses, brake, oil or undercarriage resistance. Buyers should send operating video and mechanic notes when available.
PRIMA can quote travel motor or final drive options, but the quote should not pretend a guessed diagnosis is confirmed proof.
| Symptom | Evidence | Possible area |
|---|---|---|
| Weak travel | Video and pressure notes | Motor, pump or valve |
| Leak | Close-up photo | Seal, hose or port |
| Noise | Audio and location | Gear or motor wear |
How should condition grade change the quote?
New, aftermarket, used and rebuilt travel motors need separate evidence.
A new or aftermarket unit should show product photos, machining surfaces and packing proof. A used unit should show the actual unit and visible wear. A rebuilt unit should state repair scope and whether inspection or testing is available.
The buyer should compare price only after grade is clear. A low-cost used motor may fit an older machine, but it should not be presented as the same risk level as a new replacement.
| Grade | Buyer reason | Minimum proof |
|---|---|---|
| New/aftermarket | Longer repair horizon | Fitment and QC photos |
| Used | Budget repair | Actual-unit condition |
| Rebuilt | Repairable core | Repair scope and test note |
What export packing protects a travel motor?
A travel motor is heavy and precision-sensitive.
The shaft, ports, flange and housing should be protected. The unit should be stable in a wooden crate or pallet with padding that prevents movement. Final photos should show the selected unit before closing.
If the order includes several drivetrain components, each part should be identifiable in the packing file so the receiving team can compare it with the approved quote.
| Packing area | Proof | Buyer value |
|---|---|---|
| Shaft | Guard or padding | Protects spline |
| Ports/flange | Caps and wrapping | Prevents contamination |
| Crate | Stable support | Reduces transport damage |
Evidence Table
| Buyer question | Evidence PRIMA should provide | Why it matters |
|---|---|---|
| Will the travel motor fit? | Old unit photos, flange, bolt pattern, shaft and ports | Reduces wrong-part risk |
| Is the diagnosis reasonable? | Travel video, leak photos and mechanic notes | Avoids replacing wrong component |
| Which grade is quoted? | New, aftermarket, used or rebuilt evidence | Makes price comparison fair |
| Can it ship safely? | Shaft, port, flange and crate protection photos | Protects heavy precision part |
Key Facts For PRIMA Buyers
- Travel motor fitment should compare flange, bolt pattern, shaft and port layout.
- Weak travel can involve motor, final drive, pump flow, valve, hose, brake or undercarriage resistance.
- Condition grade should be separated from price before order approval.
- Export packing should protect shaft, ports, flange and housing.
Buyer FAQ
Is machine model enough for travel motor matching?
No. Old unit photos, flange, bolt pattern, shaft and port layout are needed.
Does weak travel always mean the travel motor is bad?
No. Pump, valve, brake, final drive or undercarriage issues can look similar.
Can used travel motors be acceptable?
Yes, when actual-unit condition and warranty boundary are clear.
What should packing photos show?
The selected unit, shaft protection, capped ports, flange protection and stable crate support.
Conclusion
An excavator travel motor should be ordered through fitment evidence and diagnosis notes, not a model-name guess. PRIMA's safer quote file compares the old unit, condition grade and export packing before shipment.
