Alten Gearbox Repair & Remanufacturing

An Alten gearbox is a device that transfers power from the motor to the screw of the extruder, which is a machine that melts and shapes plastic materials. An Alten gearbox is an essential component of the extrusion process, but it can also face some challenges over time. Continuous use and external factors can lead to wear and damage, affecting the efficiency and safety of the gearbox. That’s why you must know how to use and maintain your Alten gearbox properly and when to seek professional repair and remanufacturing services.

Common Causes of Gearbox Failures

Before we explore the solutions for gearbox problems, let’s understand why they occur in the first place. Some of the common causes of gearbox failures are:

• Dirt and contamination: Dust, debris, moisture, or foreign particles can enter the gearbox and cause abrasion, corrosion, or clogging of the gears, shafts, seals, bearings, or other components.

• Lack of lubrication: Lubrication is vital for reducing friction, heat, and wear between the moving parts of the gearbox. If the lubricant level is low, dirty, or incompatible, it can increase friction, heat, and wear, leading to premature failure.

• Misalignment: Misalignment occurs when the gearbox is not properly aligned with the motor and the screw of the extruder. This can cause excessive vibration, noise, or stress on the gearbox components, resulting in damage or breakage.

• Operational errors: Operational errors refer to mistakes or negligence in using or maintaining the gearbox. For example, overloading, overspeeding, improper installation, incorrect settings, or insufficient inspection can all lead to gearbox failure.

These causes can manifest in various symptoms, such as leaks, cracks, noises, vibrations, overheating, or reduced performance. If you notice any of these signs, you should act quickly and seek professional help before it’s too late.

The Alten Gearbox Repair Process

The first step in solving any gearbox problem is a thorough inspection. This involves assessing the condition and functionality of the gearbox components and identifying the root cause of the failure. Based on this analysis, a free estimate is provided for the repair cost and time. The repair process then involves using advanced tools and techniques to fix or replace the faulty components and restore the gearbox to its original efficiency. Some of the tools and techniques used are:

• Line boring: Line boring is the process of machining or enlarging a hole that has become worn or distorted over time. It is used to repair damaged shafts or housings of the gearbox and ensure proper alignment and fit.

• Reverse engineering: Reverse engineering is the process of recreating or improving a product by analyzing its design and functionality. It is used to repair or upgrade gearboxes that have missing or outdated schematics or specifications.

Benefits of Gearbox Remanufacturing

Sometimes, repairing a gearbox is not enough. You may need to remanufacture it to give it a new life. Remanufacturing is the process of rebuilding a gearbox from scratch by replacing all its worn-out parts with new ones and optimizing its design and performance based on its usage patterns. Remanufacturing has many benefits over repairing, such as:

• Extending the lifespan of the gearbox

• Improving the efficiency and reliability of the gearbox

• Reducing the environmental impact of discarding old gearboxes

• Saving money in the long run by avoiding frequent repairs

Case Study: Successful Alten Gearbox Remanufacturing

To illustrate the value of remanufacturing, let’s look at a real-life example. A local manufacturing unit had an Alten gearbox that was showing signs of strain after years of service. They contacted Extruder Gearbox Repair, which is a leading name in machinery maintenance. Our experts didn’t just stop at repairing the visible damage. We went beyond that by analyzing the entire system, identifying weak points, and implementing upgrades. After remanufacturing, the client witnessed a 30% improvement in efficiency, proving the worth of comprehensive Alten gearbox rebuilds.

Choosing the Right Service Provider

The quality of your gearbox repair or remanufacturing depends largely on your choice of service provider. When selecting a service provider, you should always look for industry certifications and adherence to standards. But that’s not all. You should also look for additional benefits, such as:

• Emergency service: You never know when your gearbox might fail. You need a service provider that can respond quickly and provide 24/7 emergency service.

• Free pick-up: You don’t want to waste time and money transporting your faulty gearbox to the service center. You need a service provider that can offer free pick-up and delivery of your gearbox.

• Expertise: You don’t want to entrust your gearbox to amateurs or generalists. You need a service provider with specialized expertise in gearbox repair and remanufacturing and who uses reverse engineering in their toolkit.

Preventive Measures and Maintenance Tips

The best way to avoid gearbox problems is to prevent them from happening in the first place. By following some simple preventive measures and maintenance tips, you can keep your gearbox in top shape and avoid costly repairs or replacements. Here are some tips to follow:

• Regular checks: You should inspect your gearbox regularly for any signs of wear or damage, such as leaks, cracks, noises, vibrations, overheating, or reduced performance. If you notice any of these signs, you should seek professional help immediately.

• Lubrication: You should lubricate your gearbox regularly using the right type and amount of oil for your gearbox. You should also change the oil regularly according to the manufacturer’s schedule. This will help reduce friction, heat, and wear between the moving parts of the gearbox.

• Alignment: You should align your gearbox properly with the motor and the screw of the extruder to ensure optimal operation and prevent vibration, noise, or stress on the gearbox components. You should also check for any loose or missing bolts, nuts, washers, screws, or other fasteners that may affect the alignment.

• Settings: You should adjust your gearbox settings according to the manufacturer’s instructions and specifications. This includes following the recommended operating parameters like speed, torque, temperature, pressure, and load. You should also consult the manufacturer’s manual or website for any troubleshooting tips or solutions.


An Alten gearbox is a key component of the extrusion process but can also face some challenges over time. By following the right approach to maintenance, repair, and remanufacturing, you can keep your gearbox running smoothly and efficiently for years to come.
