Repairing a 100 Tonne Jack Cylinder Rod - A Comprehensive Overview

💡The 100 tonne jack cylinder rod is commonly used in the mining industry to lift heavy machinery.

🔧The rod is prone to damage from dents, scratches, and worn-out threads, which require repair and re-manufacturing.

🛠️The repair process involves re-chroming the rod, machining it to its final size, and tapping new threads.

🔩Attention to detail is crucial to avoid mistakes during the machining process, such as drilling and tapping the hole for a grub screw.

👨‍🔧The professionalism and expertise of Cutting Edge Engineering ensure high-quality repairs at a competitive price.

What causes dents and scratches on the rod?

—Dents are typically caused when the extended jack rod comes in contact with components like diffs, wheel ends, or trailing arms. Scratches result from rotational force when there's incomplete contact between the cylinder head and the machine being lifted.

Why is re-chroming necessary?

—Re-chroming is essential to restore the smooth surface of the rod, protecting it from further damage and ensuring optimal performance.

Can worn-out threads be repaired?

—Yes, worn-out threads can be repaired by machining the rod to remove the damaged area and then tapping new threads.

What is the role of the grub screw?

—The grub screw is used to lock the piston from turning on the rod, preventing potential issues like galling and damage during operation.
