191-1384 final drive for Caterpillar 305 305.5 306 mini excavator
If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

Component Type: Integrated Travel Motor and Planetary Final Drive Gearbox.
Function: Provides the high-torque output necessary for machine tracking, counter-rotation, and climbing capability in compact and confined job sites.
13-Year Specialized Authority: Supplied by a professional factory with over a decade of expertise in mini excavator undercarriage and transmission systems.
2. OEM Compatibility
Direct Fit Part Numbers: This unit is 100% interchangeable with Caterpillar part numbers 191-1384, 330-7517, 1911384, and 3307517.
Machine Fitment: Specifically engineered for the CAT 305, 305.5, 306 series mini excavators.
Installation Design: Features standard OEM mounting hole patterns and hydraulic port locations (A/B travel ports, plus Case Drain and Two-Speed pilot ports) for a seamless "drop-in" replacement.
3. Technical Specifications and Performance
Motor Type: High-efficiency axial piston motor with integrated two-speed (high/low) capability.
Gearbox Design: Multi-stage planetary reduction system utilizing hardened gear steel for maximum breakout torque and durability.
Sealing Technology: Equipped with high-performance "floating seals" (mechanical face seals) to prevent oil leakage and protect internal gears from mud, water, and debris.
Operating Pressure: Rated to handle the standard hydraulic relief settings of the CAT 305/306 series, ensuring consistent tracking speed and power.
4. Why Partner With a 13-Year Industry Expert?
Technical Precision: We understand the nuances of the CAT mini excavator hydraulic circuits, ensuring our motors match the original displacement and speed ratios.
Quality Assurance: Every final drive undergoes a rigorous bench test, including torque load testing and seal integrity checks, before being cleared for shipment.
Global Logistics: Shipped in reinforced, shock-proof packaging via DHL, FedEx, or UPS, typically arriving within 3 to 7 business days.
Direct Factory Pricing: Benefit from optimized supply chains and competitive wholesale rates, providing a cost-effective alternative to local dealer prices.
5. Essential Installation Protocol
Case Drain Connection: Ensure the case drain line is connected and unobstructed. Excessive backpressure in the case drain can cause the motor shaft seal to blow out.
Gear Oil Maintenance: The planetary gearbox section must be filled with the correct grade of gear oil (usually SAE 80W-90) before operation. Always check oil levels after the first few hours of use.
Hydraulic System Cleanliness: Always inspect hydraulic hoses for debris before connecting. Contaminated oil is the leading cause of premature piston wear in travel motors.
6. Ordering Information
Fitment Verification: Please share your machine's Serial Number or the number of mounting holes on the frame and sprocket to ensure 100% fitment accuracy.
Support: Our technical team is available 24/7 to assist with installation guidance and hydraulic troubleshooting.
