It is crucial to check the machine's serial number and the number of hydraulic ports (1 hole) on the old housing.

Related Parts and Hardware

The housing works with the hydraclamp piston. Replacing the housing often involves replacing a damaged or corroded piston. It is also worth checking the condition of the hydraulic hoses supplying oil.

⚠️ Safety Warning

A faulty hydraclamp (leak, cracked housing) causes the kingpost with the entire backhoe attachment to slide sideways uncontrollably during work. This creates a huge risk to machine stability and the safety of people nearby.

Part Role in the Machine and Failure Diagnostics

The hydraclamp is a hydraulic brake that locks the lateral movement of the rear arm on the frame (slide). The lower housing contains a piston that presses the arm against the frame under pressure.

  • › Hydraulic oil leak from around the lower kingpost mount.
  • › Unable to lock sideshift (arm slides loosely).
  • › Visible crack in the housing body (often from impact or frost).
  • › Corrosion inside the cylinder preventing piston movement.

🔧 Expert Guide: Key Installation Tips

  1. Version Verification: Ensure you need the 1-port housing. Older machines had a 2-port version.
  2. Cleanliness: Before installation, thoroughly clean the mating surface of the housing to the kingpost frame.
  3. Seals: The housing comes with the piston seal pre-installed. However, check the condition of o-rings sealing the housing-to-frame connection (if present).
  4. Bleeding: After installation, slide and lock the arm several times to bleed the hydraulic hydraclamp system.

Frequently Asked Questions (FAQ)

How does this housing differ from the 2-port version?

The 2-port version (older type) had separate supply and return or series connection. The 1-port version (newer type, since 2001) is supplied by a single line. They are not interchangeable.

Is the piston included?

No. The set includes the housing and the seal installed within it. The piston must be transferred from the old housing (if serviceable) or purchased separately.
