Related Parts and Hardware

When replacing the lock, we recommend checking the condition of the outer handle (with key), the inner handle, and the door gas strut, which prevents slamming.

⚠️ Safety Warning

A faulty door lock poses a serious risk. It can lead to the door opening unexpectedly during travel or operation on a slope, which risks the operator falling out of the cab. It also protects the machine from theft and vandalism.

Part Role in the Machine and Failure Diagnostics

The 121/13400 lock is a latching mechanism hidden inside the left cab door. It is connected by rods or cables to the inner and outer handles and (in some cases) the key barrel. Its job is to securely latch the door in the closed position and release the latch when a handle is pulled.

  • › Door will not latch or "catch" the striker.
  • › Unable to open the door from the inside or outside (handle feels loose).
  • › Having to slam the door repeatedly to make it close.
  • › The lock jams, especially in cold weather.
  • › Door opens on its own during travel (due to vibrations).

🔧 Expert Guide: Key Installation Tips

  1. Verify Side: Ensure this is the left-hand (LH) lock, intended for the driver's side door.
  2. Remove Door Panel: Accessing the lock requires removing the inner door panel (trim).
  3. Adjust Linkages: After installing the new lock, correct adjustment of the rods/linkages connecting it to the handles is crucial.
  4. Lubrication: It is recommended to lubricate the moving parts of the new lock with grease before installation for smooth operation.
  5. Adjust Striker: Check the position of the striker (latch bolt) on the cab frame. Minor adjustments may be needed for the door to close perfectly.

Frequently Asked Questions (FAQ)

How do I know if I need a left or right lock?

The side is determined from the operator's perspective sitting in the cab. This lock (121/13400) is for the door on the operator's left side.

Does this lock fit newer 3CX/4CX models?

No. This model (121/13400) is for older model machines. Newer machines (e.g., post-2010) typically use a different lock mechanism (like 123/02451).

Does this kit include handles and a key?

No, this product is only the internal lock mechanism (cassette). The outer handle, key barrel, and inner handle are all sold separately.
