Roll pin 85812306 Carraro, aftermarket

For the backhoe loaders with Carraro axles: roll pin 85812306, an aftermarket part. This is a slotted roll (spring) pin used in the differential.

The pin is chosen by part number according to its diameter, length and end form. When replacing it, check the gears, bushes and bores it works with, since a new pin in a worn bore soon develops play. Small retaining parts such as spring (tension) pins are not reused once removed, but replaced with new ones. Most pins are made of hardened steel with a ground surface, so their dimensions must match those of the old pin exactly.

Specifications

Compatibility

According to the product card, Carraro 85812306 is a pin. Fit is confirmed by the axle or transmission type. Other parts are in Carraro.

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.
