Loader bucket pin 811/80001 JCB 3CX, 4CX, 5CX, Ø44.45 x 219 mm

Loader bucket pin 811/80001 is an aftermarket pin for JCB 3CX, 4CX, 5CX backhoe loaders; diameter 44.45 mm, length 219 mm. The card also lists 811/90483.

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.
