Product Overview
Cat specifies 3P-5955 as a clutch friction disc with a hardened steel core and spiral/radial groove pattern designed to promote cooling. The 101-tooth internal spline provides the engagement geometry for the applicable transmission/clutch pack.
Manufacturer data adds important fitment beyond the original title, including 815/816 compactors, 950/966C loaders and 140G grader applications. Exact transmission arrangement should still be verified by machine serial number.
