Track rod 149437 Carraro, aftermarket

Track rod 149437 is an aftermarket part for the backhoe loaders with Carraro axles.

The track rod transmits the steering cylinder's movement to the hub knuckles and makes both wheels turn together. When the ball joints at its ends develop play, the steering feels loose, the machine wanders on the road and the front tyres wear unevenly. If the rod is bent by an impact, the wheel alignment is lost. A worn track rod is replaced without delay, as it can lead to loss of steering control. Lay the new rod beside the old one to compare the length and taper ends.

Fitting

Before fitting the rod, clean the taper holes in the knuckles and check them for ovality, since a ball joint will not seat tightly in a worn hole. After torquing the nuts, fit new split pins, lock the adjusting nuts and check that both rod ends lie in the same plane. Recheck the nut torque after the first hours of work. When choosing a rod, compare it with the old one for length, thread direction and ball joint tapers, since a rod of a different length can make it impossible to set the toe-in. A bent rod is replaced, not straightened, because straightened steel is weakened and can bend again under load. Watch tyre wear in the first weeks after the change.
