Dowel pin 115640 Carraro, genuine

Dowel pin 115640 is a genuine JCB part for the backhoe loaders with Carraro axles. This is a dowel pin that aligns two parts to each other.

Pins inside the axle and in the steering joints hold gears, brake plates or joints in the right position and carry load. The differential pin is the axis on which the planet gears turn; brake reaction pins stop the brake plates rotating and pass the braking torque to the axle casing; steering pivot pins are the pivot point of the knuckle joints. A worn pin causes play, knocking and rapid wear of the related gears or bores. Most pins are made of hardened steel with a ground surface, so their dimensions must match those of the old pin exactly.

Fitting

The pin comes new. Before fitting, lubricate it with clean axle oil or grease and slide it squarely into its bore without hammering. Renew the retaining parts (circlips, tension pins, split pins). After assembly, fill the axle with the specified oil and grease the steering pin nipples. Before fitting the pin, measure the bore diameter, and repair an oval or scored bore along with the pin change. For differential pins, also check the thrust washers and inner surfaces of the planet gears, since worn washers increase the gear clearances and make the differential noisy on turns.
