These essential spare parts ensure the connection between the various mechanical components of your construction equipment. Whether you are looking for a bucket pin, transport pin, or pivot pin for your CASE machinery, our selection of reconditioned pins provides the reliability needed for your projects. Discover how to select the right pin for your model and optimize your maintenance budget.
What is a transport pin for a mini excavator?
A transport pin is a cylindrical metal rod that enables the rotation and pivoting of attachments on your mini excavator. This fundamental technical part passes through the articulation bushings to securely connect the bucket to the arm or the boom to the frame.
Typically made from hardened 42CrMo4 steel, the pin withstands the intense mechanical stresses of construction sites. Its diameter varies depending on the machine's tonnage, ranging from 20 to 45 mm for mini excavators. Some models include automatic lubricators that continuously grease the articulation points, significantly extending the overall lifespan.
How to determine the pin and diameter for your CASE?
- Check the exact model of your CASE mini excavator (CK13, CK15, CX20B, CX22B) on the manufacturer’s plate.
- Measure the existing diameter using a caliper: 25mm for CK13, 30mm for CK15/CX20B.
- Verify the center-to-center distance between the two attachment points on the bucket or related accessory.
- Identify whether the original pin includes an automatic lubricator before ordering.
- Note the total required length, taking into account the thickness of the arm (95mm to 130mm).
- Refer to the manufacturer's position diagram to precisely locate pins 8, 9, 10, 11.
- Prefer complete pin-and-bushing kits to ensure perfect compatibility with your CASE equipment.
The pins are mainly compatible with CASE mini excavators from the CK series, including models CK25, CK32, CK36, and CK38. Some pins also fit CASE compact loaders 21F and 121F depending on technical specifications. Compatibility depends on the pin diameter and bucket dimensions, as each model has its own mounting requirements.
Visually inspect the pin to detect any cracks, excessive wear, or corrosion along its entire length. Ensure the surface is free from deep scratches and that dimensions comply with original specifications. Check for deformation by rolling the pin on a flat surface and test the play in the mounting holes.
Used pins allow for substantial cost savings compared to new ones, typically priced 40 to 60% lower. This cost-effective option offers excellent value for professionals who want to maintain their equipment without heavily impacting their operating budget.
Installing a mini excavator pin requires technical skills and specialized tools for precise disassembly and reassembly. The procedure demands correct torque application, use of pullers, and sometimes heating bushings to facilitate fitting. Without experience in construction equipment mechanics, it is advisable to entrust this task to a professional.
The lifespan of a CASE pin ranges between 5,000 and 15,000 hours of operation depending on usage intensity and working conditions. Regular maintenance with proper lubrication can significantly extend its durability. Dusty or abrasive environments reduce service life, while moderate use on standard terrain optimizes wear resistance.
