The Michigan Clark 55 loader is a powerful and versatile piece of heavy equipment, known for its ability to handle demanding tasks on construction sites, in quarries, and in other heavy-duty applications. However, like any piece of machinery, the Michigan Clark 55 can face mechanical issues over time. One such issue involves cracks in the lower steering trunnion flange, a critical component of the loader's steering system. This article explores the nature of this problem, its implications, potential causes, and recommended solutions, while also providing insight into proper maintenance practices for the Michigan Clark 55 loader.
Understanding the Steering Trunnion Flange in the Michigan Clark 55
The lower steering trunnion flange is a crucial part of the loader's steering system. The trunnion itself is a rotating shaft or support structure that allows movement, in this case, enabling the loader's wheels or tracks to steer. The flange is the flat, circular surface that connects the trunnion to other components, like the steering cylinder or the axle assembly.
In the case of the Michigan Clark 55 loader, the lower steering trunnion flange plays a key role in the smooth operation of the loader’s steering system, ensuring precise handling and maneuverability, especially when turning or adjusting the loader's direction under heavy loads.
The Issue: Cracks in the Lower Steering Trunnion Flange
A common problem reported by operators and mechanics is the development of cracks in the lower steering trunnion flange. These cracks can compromise the integrity of the steering system and lead to a series of performance and safety issues. Cracks in this component are often caused by the stresses placed on the flange during operation, especially when the loader is subjected to heavy loads, sharp turns, or rough terrain.
Addressing a cracked lower steering trunnion flange requires careful attention and a proper repair process. If left unaddressed, the crack can worsen over time, leading to a total failure of the steering system. Repairing this component typically involves the following steps:
To avoid the recurrence of cracks in the lower steering trunnion flange, operators should adopt a proactive maintenance routine:
In one case, a Michigan Clark 55 loader was operating on a heavy-duty construction site. The loader was tasked with lifting large loads of material, and over time, operators began noticing that the steering felt increasingly unresponsive. Upon inspection, a mechanic discovered small cracks in the lower steering trunnion flange, likely caused by years of heavy use combined with sharp maneuvers.
Rather than replacing the entire flange, the team opted to repair the crack using welding and reinforced the flange with a custom support plate. The loader returned to full operation, and with regular maintenance checks, the steering system continued to function well for several more years.
Key Takeaways
The Michigan Clark 55 loader is a tough and reliable piece of machinery, but like all heavy equipment, it requires diligent maintenance to ensure that it operates efficiently over time. Cracks in the lower steering trunnion flange can be a common issue, but with proper inspection, repair, and preventative care, these problems can be addressed to keep the loader functioning at its best. By understanding the potential causes and solutions for this issue, operators can ensure that their Michigan Clark 55 loader remains a reliable tool on the job site for years to come.

A common problem reported by operators and mechanics is the development of cracks in the lower steering trunnion flange. These cracks can compromise the integrity of the steering system and lead to a series of performance and safety issues. Cracks in this component are often caused by the stresses placed on the flange during operation, especially when the loader is subjected to heavy loads, sharp turns, or rough terrain.
- Causes of Cracks in the Steering Trunnion Flange:
- Excessive Load Stress: The Michigan Clark 55 loader is designed to handle heavy lifting and hauling tasks, but excessive or uneven loading can place undue stress on the steering system. Sharp turns or abrupt maneuvers can exacerbate these forces, leading to cracks in the trunnion flange.
- Fatigue from Repeated Use: Over time, the trunnion flange can suffer from metal fatigue due to continuous use under high-stress conditions. This can lead to small, hairline cracks that expand gradually, especially in areas of the flange that experience the most stress.
- Improper Maintenance: Lack of regular inspection and maintenance can also contribute to the development of cracks. If the flange is not properly lubricated, or if the steering system is not aligned correctly, it can cause uneven pressure on the component, leading to stress and eventual cracking.
- Material Defects: In some cases, the material used in the fabrication of the flange may be flawed, leading to weaknesses that can cause cracks to form under normal operating conditions.

- Symptoms of Cracks in the Trunnion Flange:
- Steering Issues: One of the first signs of a crack in the lower steering trunnion flange is difficulty steering the loader. Operators may notice that the loader's steering feels less responsive or that it struggles to maintain a straight line.
- Unusual Noises: Cracking in the flange may cause strange noises, such as popping or grinding, particularly when the loader is making sharp turns or under load.
- Visible Cracks: In more severe cases, visible cracks may appear on the lower steering trunnion flange. These cracks can sometimes be seen by visually inspecting the component during routine maintenance checks.

Addressing a cracked lower steering trunnion flange requires careful attention and a proper repair process. If left unaddressed, the crack can worsen over time, leading to a total failure of the steering system. Repairing this component typically involves the following steps:
- Inspection and Assessment:
- Before proceeding with any repairs, the loader must be inspected thoroughly. The crack's size, location, and depth should be assessed to determine the extent of the damage. Small cracks may be repairable, while larger or more severe cracks might require replacement of the flange altogether.

- Welding the Crack:
- For smaller cracks, welding is often the solution. A skilled welder will need to use the appropriate welding technique to fill the crack and restore the integrity of the flange. The welding process must be done carefully to avoid overheating the metal and causing additional damage to the surrounding areas.
- Pre-weld preparation: Cleaning the area around the crack is essential to ensure a strong bond. Any rust, dirt, or debris must be removed before welding.
- Post-weld inspection: Once the crack is welded, it’s important to inspect the repair for signs of weakness, such as new cracks or warping.
