Quality Assurance Process

Our agricultural gearboxes undergo rigorous quality checks before shipment. These checks include:

Appearance Inspection

The gearbox is visually checked for any surface defects that could affect its performance or lifespan.

Dimensional and Assembly Check

We measure the dimensions of the gearbox and its components to ensure they meet the specified tolerances. The assembly is also checked to ensure it is correctly done.

Functional Testing

This involves checking the gearbox’s rotation for smoothness and accuracy of the transmission ratio.

Noise Testing

We test the gearbox under load to ensure it operates within the acceptable noise levels.

Clearance and Lubrication Inspection

The gearboxes are inspected for proper axial and radial clearances. The lubrication system is also checked to ensure it is functioning correctly.

Sealing Inspection

The sealing of the gearbox is inspected to prevent oil leakage and dust intrusion.

Selecting the Right Gearbox for Your Machinery

Several factors need to be considered when choosing the right gearbox for your farming machinery. These include:

Power Requirements

The gearbox should be able to handle the power output of your machinery. A gearbox with insufficient power capacity can lead to premature failure.

Input/Output Speed Ratio

The input/output speed ratio needs to match the requirements of your machinery. An incorrect ratio can affect the machinery’s operation.

Torque Requirements

The gearbox needs to handle the torque produced by your machinery. If the gearbox’s torque capacity is too low, it can lead to gearbox failure.

Reduction Ratio

The reduction ratio is the ratio of the input speed to the output speed. This needs to match the requirements of your machinery.

Life Expectancy and Durability

The gearbox should have a long lifespan and be able to withstand the harsh conditions of farming.

Compactness and Weight

The gearbox should be compact and lightweight to avoid adding unnecessary weight to the machinery.

Environmental Conditions

The gearbox should be able to operate in the environmental conditions where the machinery will be used.

Maintenance Requirements

The gearbox should be easy to maintain to reduce downtime and maintenance costs.


The gearbox should provide good value for money. It should deliver high performance and durability at a reasonable price.

When to Replace Your Gearbox

It’s essential to know when your gearbox might need a replacement. Some signs to look out for include:

Increased Noise

If your gearbox is making more noise than usual, it could be a sign of worn-out components.

Oil Leaks

Oil leaks can indicate a problem with the gearbox’s seals, which might necessitate a replacement.

Drop in Reduction Efficiency

If the gearbox is not reducing speed as efficiently as it should, it might need a replacement.

Damaged Gears or Bearings

If the gears or bearings in the gearbox are damaged, a replacement might be necessary.

Difficulty in Rotation or Jamming

If the gearbox is difficult to turn or gets jammed, it could be a sign that it needs a replacement.

Vibrations or Shaking

If the gearbox vibrates or shakes during operation, it could indicate a problem that might require a replacement.

Steps to Replace a Gearbox

Replacing a gearbox involves several steps:

Shutdown and Disconnect the Power

Before starting the replacement process, it’s important to shut down the machine and disconnect it from the power source.

Remove the Old Gearbox

The old gearbox is removed from the machine.

Clean the Working Area

The working area is cleaned to prepare for the installation of the new gearbox.

Install the New Gearbox

The new gearbox is installed in the machine.

Connect the Drive System

The drive system is connected to the new gearbox.

Test and Adjust

The machine is tested to ensure the new gearbox is working correctly. Any necessary adjustments are made.
