Short Description:

CAT 151-5966 front gear pivot is the supporting base of front gear assembly. It provides rotary support for the gear, transmits torque and maintains gear meshing concentricity for overhaul of heavy-duty auxiliary drive systems.

description

It is forged from solid steel with surface hardening, equipped with locating pin holes and multiple mounting holes. The integrated flange and center hub structure delivers high rigidity and torsion resistance. It acts as the rotating seat for the front gear, limiting radial runout and absorbing impact load during power transmission. Worn or deformed pivot causes uneven gear wear, noise, jumping teeth and gear failure. It fits front gear drive assemblies for Cat heavy-duty machines, commonly used for auxiliary pump and fan drive, built for dusty, high-impact mining and construction sites.

Product Advantages

1. One-piece flange construction keeps stable alignment, controls gear concentricity and reduces meshing noise and uneven wear.
2. Hardened hub surface resists compression and fatigue and stays stable under cyclic torque load.
3. Built-in locating pin feature simplifies positioning and prevents angular offset during assembly.
4. OEM hole pattern allows direct drop-in replacement without extra machining.

FAQ 

Q: What symptoms indicate a failed 151-5966?
A: Persistent gear train noise, rapid uneven gear wear, power fluctuation and repeated seal leakage.

Q: Can I reuse the old gear with this new pivot?
A: It is acceptable after runout and backlash inspection. Replace the gear if teeth are heavily worn.

Q: Can I install it without the locating pin?
A: Not recommended. The pin locks angular position; missing pin leads to misalignment and premature failure.
