Products Description
The transmission's power flow starts at the engine and passes through the hydraulic torque converter and universal joint before entering the transmission through the input coupling and input shaft. From there, the power is transferred through the planetary assemblies and selected clutch members before leaving through the output shaft.
The five planetary rows do not all perform the same job. The first three are connected with forward/reverse control, while the fourth and fifth provide the three travel speeds. This arrangement gives the Mechanical Transmission Gearbox six defined ratios while keeping the direction and speed functions within the same transmission housing.
With 120 kW maximum input power, the unit corresponds approximately to the 160hp mechanical transmission class.

Product Features
- Five planetary gear sets
- Five disc clutches
- Three forward ratios
- Three reverse ratios
- Double-planet arrangement in the third planetary set
- Hydraulic control valve for clutch engagement
- 120 kW maximum input power
- 2,062 N·m maximum input torque
- 2 MPa main oil pressure
- 0.07–0.18 MPa lubrication pressure
The transmission uses two clutches at a time to establish the required gear and direction. For example, forward first gear uses clutches 1 and 3, while forward third gear uses clutches 1 and 4. Reverse gears use clutch 2 together with clutch 3, 5 or 4.
Product Advantages
The Mechanical Transmission Gearbox has clearly defined ratios for both directions, which makes the transmission specification relatively straightforward when matching a replacement unit.
Its five-planetary layout also separates the functions inside the gearbox. The first three planetary rows handle direction-related transmission, while the last two are used for speed changes. The third planetary set is a double-planet design, allowing the output direction to be reversed within the transmission structure.
Another practical point is that the manual provides specific operating and maintenance requirements. Before shifting into gear, the engine should be running normally and both control and lubrication oil pressure should be within the required range.
Product Applications
The T160 transmission can be used in:
- Bulldozer drivetrain systems
- Construction machinery
- Earthmoving equipment
- Transmission replacement projects
- Transmission refurbishment
- Forward/reverse travel systems
- Low-speed working conditions
- Machines using a mechanical transmission
It is suitable for applications where the existing transmission needs to provide three forward and three reverse ratios within the specified input power and torque range.
Customization Options
For a Mechanical Transmission Gearbox replacement, the following information can be used for technical matching:
• Existing gearbox model
• Bulldozer model
• Input shaft information
• Output connection
• Installation dimensions
• Input power
• Input speed
• Input torque
• Forward/reverse ratios
• Technical drawings
• Photos of the original unit
For special configurations, the existing transmission should be checked against the T160 dimensions and operating parameters before production or shipment.
FAQ
Q: What is the maximum input power of the T160 transmission?
A: The maximum input power specified in the manual is 120 kW, which is approximately 160 hp.
Q: What is the maximum input torque?
A: The maximum input torque is 2,062 N·m at 1,100–1,200 r/min.
Q: How many speeds does the transmission have?
A: There are three forward speeds and three reverse speeds.
Q: What are the forward transmission ratios?
A: The forward ratios are 2.080, 1.176 and 0.710 for first, second and third gear respectively.
Q: What oil should be used?
A: The manual specifies No. 8 hydraulic transmission oil. It also states that the oil must be strictly filtered before being added.
Q: How often should the transmission oil be changed?
A: The maintenance schedule calls for an oil change at 600 hours, together with cleaning the oil pan and oil filter.
Q: What should be done if the clutch slips?
A: The manual lists low control oil pressure, a blocked oil filter, blocked oil passages and worn friction plates as possible causes. Corresponding measures include checking the control valve, cleaning the filter or oil passages, and replacing worn friction plates.
Q: Can forward and reverse be changed while the machine is moving?
A: No. The manual states that forward/reverse changes should be made after the vehicle has stopped. Gear changes should be made one step at a time.
