FAQ

Q1: How do I confirm this coupler fits my Bobcat E32?
A: Please measure the outer diameter of your old coupler. It should be exactly 150mm. Also, count the internal spline teeth. This part has 50 teeth. If both measurements match, it is a direct replacement for your machine.

Q2: Is the nylon material strong enough for heavy digging?
A: Yes. This is a professional-grade nylon composite specifically engineered for heavy equipment. It acts as a “fuse” to protect the engine and pump from shock loads. It is stronger than standard rubber and designed to withstand the high torque of mini excavators.

Q3: What is the installation procedure?
A: Installation is straightforward. Align the splines of the coupler with the hydraulic pump shaft. Then, bolt the flange of the coupler to the engine flywheel. Ensure all bolts are torqued to the manufacturer’s specifications. No special tools are required. We recommend replacing the bolts if they are worn.
