860134620 143874 Carraro Brake Disc – Paper Friction Disc for XCMG Wheel Loader Braking System

860134620 / Carraro 143874 Brake Disc — Paper Friction Disc for Wheel Loader Wet Braking & Transmission System

The brake disc (Customer PN 860134620 / Carraro Ref. 143874) is a critical paper friction component within Carraro drive-train and wet braking systems used across construction machinery, particularly wheel loaders . As a PAPER DISC​ in the wet multi-disc brake pack or wet clutch pack, it works in conjunction with steel separator plates and end plates to deliver the reliable friction needed to slow, stop, or hold machinery in place under immense torque, sudden impact loads, and constant gear/direction changes .

Per Carraro's original specification, part 143874 is built to the following exact dimensions :

• Type:​ PAPER DISC (paper-based friction plate)

• Outer Diameter:​ 223.0 mm

• Inner Diameter:​ 71.0 mm

• Thickness:​ 4.9 mm

• Spline:​ 36 teeth, internal spline (36 INT TH)

• Oil Groove:​ 2 PASS

• Material:​ FP (paper friction material)

• Weight:​ 0.75 kg

This part is a direct replacement for Carraro 143874​ and is cross-referenced across multiple OEM platforms. Per Aydınonat Friction Products' Machineryline listing, Carraro 143874 carries the following OEM equivalent references :

Additionally, SourcingAI lists part 143874 as a "Durable Transmission Friction Disc 143874 / 143-874 BRAKE LINING" — a friction & braking product for Carraro applications, new condition, sufficient stock, minimum order 10 pieces .
