COBRA MECHANICAL QUICK HITCH (45/50MM) SUITABLE FOR CATERPILLAR - 2730799

Technical Specification and Compatibility

A premium, reinforced mechanical quick hitch from the COBRA series. Designed for the rear dipper arm of CATERPILLAR D, E, and F series backhoe loaders (e.g., 428D, 428E, 432E). It allows for instant attachment changes (buckets, rippers). The COBRA model features internal reinforcements to prevent twisting under load and a special shell design that resists clogging (e.g., in clay). The quick hitch is brand new, complete, and ready for installation (does not include mounting pins for the arm).

HIMACORE specializes in providing the highest quality hydraulic parts for construction machinery. Our products, such as hydraulic pumps, motors, and valves, are designed for maximum performance and reliability in the toughest working conditions. By choosing HIMACORE, you are investing in the precision, durability, and operational certainty of your machine's hydraulic system.

Essential for Installation & Use

  • › Mounting pins (45 mm and 50 mm): For mounting the hitch to the machine's arm (not included).
  • › Quick hitch key/bar: Necessary to operate the locking mechanism.
  • › HYPTRON Grease: For regular lubrication of the locking mechanism and pins.

Application in machines

Brand Type / Series / Model
CATERPILLAR (CAT) Backhoe Loaders: 428D, 428E, 428F, 432E, 438, 442, 444

The list above is for reference. You must verify your dipper arm dimensions: Pin diameters (45mm/50mm), widths (205mm/255mm), and pin centers (345mm).

⚠️ Safety Warning

Never operate with a suspended attachment unless you are 100% certain the quick hitch mechanism is correctly and fully locked. Always perform test curls and movements close to the ground after changing an attachment. An unexpectedly detached bucket can cause fatal injury.

Part's Role in the Machine and Failure Diagnostics

A mechanical quick hitch radically shortens the time needed to change attachments, increasing machine efficiency. Its failure or wear mainly manifests as problems with securely attaching buckets.

  • › Growing play (slop) between the hitch and the bucket.
  • › Difficulty locking or unlocking the mechanism (seizing, corrosion).
  • › Visible cracks on the welds or body of the hitch.
  • › Ovalization (egging) of the pin holes for mounting to the dipper arm.

🔧 Expert's Guide: Key Installation Tips

  1. Cleanliness is key: Before attaching a bucket, always ensure the bucket hooks and the inside of the quick hitch are clean (no dirt, rocks, or ice).
  2. Lubricate the mechanism: Regularly grease the moving parts of the locking mechanism and any grease zerks on the hitch (e.g., with HYPTRON grease).
  3. Verify the lock: After every attachment change, perform a safety check: rest the bucket on the ground and try to curl and uncurl it to ensure it is securely locked on both pins.
  4. Check dipper pins: When installing the new hitch on the arm, check the condition of the arm's pins and bushings. Any play in this area will be transferred to the entire attachment.

Frequently Asked Questions (FAQ)

1. What is a COBRA hitch?

The COBRA model features internal reinforcements and a special shell design. It is designed for heavier work and performs better in sticky materials like clay, which could clog standard hitches.

2. Why does this hitch have two different pin diameters (45mm and 50mm)?

This is a characteristic feature of the hitch on CATERPILLAR D, E, and F series backhoe loaders. Unlike many excavators where both pins are the same diameter, the CAT hitch often uses one diameter pin at the dipper end and a different diameter at the linkage. This is crucial for a correct fit and working geometry.

3. What is the difference between this hitch and 1919555?

The main difference is the hitch dimensions, specifically the pin centers. This model (2730799) has 345 mm pin centers and fits the D, E, and F series machines. The 1919555 model has 370 mm pin centers and fits the older B and C series machines. They are very similar, so verifying dimensions is critical before purchase.
