Backhoe bucket pin 911/12400 JCB 3CX, 4CX, 5CX, Ø44.45 x 347 mm

Backhoe bucket pin 911/12400 is an aftermarket pin for JCB 3CX, 4CX, 5CX backhoe loaders; diameter 44.45 mm, length 347 mm.

Pins like this work under heavy shock and bending loads: during digging and loading all the force passes between pin and bushing. Lack of grease, a damaged dust seal and sand in the joint speed up wear. As play grows, the hydraulic cylinders and mounting lugs take the shocks too, so a pin that has lost diameter is best replaced without delay.

Specifications

Compatibility and selection

The pin is for the backhoe bucket joint on JCB 3CX, 4CX, 5CX backhoe loaders. Select it by part number 911/12400 and dimensions; measuring the old pin's diameter and length with a caliper avoids mistakes. Other pins are in JCB CX series pins.

Fitting

Before the new pin goes in, inspect the lugs for cracks and ovality; replace the bushing if it is worn. Drive the pin in square with light blows, fit the retainer and grease the joint. Repeat the greasing after the first working hours.
