Common Concrete Mixer Truck Repairs: Keeping Your Equipment Running Smoothly

Concrete mixer trucks are the backbone of any construction project, whether you're paving roads, laying foundations, or building large structures. However, like any heavy-duty machinery, they require regular maintenance and repairs to keep them in top condition. Below, we’ll explore some of the most common issues that affect concrete mixer trucks and provide insight into what you can do to prevent or fix them.

1. Hydraulic System Problems

One of the most frequent repairs for concrete mixer trucks involves the hydraulic system. The hydraulic system powers essential components such as the cement mixer chute, which needs to function smoothly to ensure precise delivery of the concrete mix. Over time, hydraulic components like pumps and hoses can wear down due to the high pressure and constant use, leading to leaks or reduced performance.

Tip: Regularly inspect hydraulic lines and seals for wear. Using high-quality parts, like Schwing concrete pumps, will help to ensure longevity and consistent performance. Check out our hydraulic system parts.

2. Drum Wear and Tear

The mixer drum is arguably the hardest-working part of the truck. Day in and day out, it is responsible for mixing and transporting concrete. Over time, the inner lining of the drum can wear down, especially if not properly maintained. This wear can result in uneven mixing or, in extreme cases, breakdowns during operation.

To keep your mixer drum in good shape, check for signs of rust, dents, or thinning metal. Consider McNeilus parts and replacements for high-quality drum components that will stand up to the toughest conditions. Browse our selection of drum components.

3. Cement Mixer Chute Maintenance

The cement mixer chute directs concrete to the right location during unloading. A damaged or misaligned chute can make it difficult to pour concrete accurately, leading to wasted time and materials. Regular cleaning is also essential to prevent buildup that can hinder smooth operation.

Replacing or upgrading your mixer truck’s chute can be easily done with parts from trusted suppliers like Contech parts and replacements. Ensure your chute is well-maintained to keep your project on schedule. Find replacement chutes on our website.

4. Engine Malfunctions

Like any vehicle, the engine of a concrete mixer truck can suffer from wear and tear. Frequent engine malfunctions can stem from overheating, oil leaks, or clogged filters. Addressing these issues promptly is key to avoiding costly repairs and downtime. Regular engine checkups and part replacements can extend the life of your mixer truck.

When you need durable, high-performance parts to keep your engine running smoothly, McNeilus and Contech offer reliable solutions for keeping your mixer on the road. 

5. Chassis and Suspension Issues

Heavy loads and tough terrain can take a toll on the chassis and suspension system of your mixer truck. Worn-out suspension components can lead to a bumpy ride, excessive wear on tires, and potential damage to other parts of the truck. Regular inspections and timely repairs are essential for maintaining a smooth operation and preventing long-term damage.

Preventative Maintenance: The Key to Avoiding Major Repairs

Preventative maintenance is crucial to avoid costly breakdowns. Frequent oil changes, hydraulic fluid checks, and inspections of key components like the drum, cement mixer chute, and engine will extend the life of your truck. Additionally, using high-quality replacement parts from McNeilus, Schwing, and Contech ensures your mixer truck remains operational with minimal downtime.
