Failure Symptoms

The first sign of a failing bucket cylinder is often a bucket that fails to hold its position or drifts downward when under load. This can progress to slow and unresponsive bucket movements, making operation inefficient. If left unaddressed, significant hydraulic leaks can occur, leading to a loss of hydraulic pressure and inability to operate the bucket effectively.

Installation Tip

Ensure the cylinder rod is clean and free of any abrasive material before installation to prevent damage to seals. Do not reuse old mounting hardware; use new pins and retainers as specified.

Service Note

When replacing the bucket cylinder, it is advisable to inspect the hydraulic control valve for the bucket circuit and the condition of the hydraulic fluid.
