Extending dipper lock pin 911/40092 JCB, Ø44.4 x 215 mm

Extending dipper lock pin 911/40092 is an aftermarket pin for JCB 3CX, 4CX, 5CX, 520-50 backhoe loaders; diameter 44.4 mm, length 215 mm. The card also lists 333/G6734, 911/23800.

The pin lets two parts turn against each other and forms a plain bearing together with its bushing. Its life depends largely on regular greasing through the grease nipple. Scoring, a step or ovality on the pin, visible play in the joint and grease that does not come through when the nipple is pumped all show the pin needs replacing.

Specifications

Compatibility and selection

The pin is for the extending dipper lock on JCB 3CX, 4CX, 5CX, 520-50 backhoe loaders. Select it by part number 911/40092 (333/G6734, 911/23800) and dimensions; measuring the old pin's diameter and length with a caliper avoids mistakes. Other pins are in JCB CX series pins.

Fitting

When replacing the pin, measure the bushing bore and, if it is worn, fit a new one from the JCB CX bushings. Grease the pin and bushing before assembly, refit the retaining bolt or lock pin and pump the grease nipple until grease comes through.
