Track rod 128/13949 JCB 3CX/4CX, aftermarket, option 2

For the JCB 3CX and 4CX backhoe loaders: track rod 128/13949, an aftermarket part.

The track rod is checked on level ground with the engine running by turning the steering slightly each way: visible play or a knocking sound at the ball joint shows wear. If the ball joint boots are torn, dust and water get in and ruin the joint quickly. The grease nipples on the rod ends, where fitted, are greased at the service interval.

Fitting

Before removing the old rod, mark the position of the adjusting nuts. Separate the ball joint tapers with a proper splitter, since hammering can damage the knuckle bore. When fitting the new rod the tapers must be clean and dry, the nuts tightened to the specified torque and new split pins fitted. After fitting, turn the steering to full lock both ways and check that the rod fouls nothing. The track rod comes new, and its ball joint boots and nuts are checked before fitting.
