Walterscheid 139345 is a genuine IFM/R 2500 free-motion PTO profile yoke, OEM 1139345, officially classified by Walterscheid as a rotary clearance clutch. Its 60° free-motion mechanism allows limited rotational movement to help align PTO connections when attaching drivelines to tractors and agricultural implements. This makes PTO hookup easier, especially when a PTO brake or implement resistance makes the shaft difficult to rotate manually.

Designed for compatible Walterscheid W2500 Series drivelines, this free-motion yoke features a 36 mm bearing bore diameter (d), 140 mm outside diameter (D) and 135 mm length (L), excluding centering. The assembly features a roll-pin locking connection and incorporates an SC25 protective-guard groove.

The yoke features an S5 star-profile hub designed for connection to compatible Walterscheid S5 outer profile tubing, with nominal tubing profile dimensions of 47 × 61 mm (width × height). Matching W2500 telescoping driveline configurations pair the S5 outer profile with a corresponding S4 inner profile. The 2500 universal-joint family uses nominal 36 × 89 mm cross dimensions. The free-motion mechanism assists with connection alignment and is not an overrunning or overload-protection clutch.

Before ordering, verify the original OEM number, yoke dimensions, W2500 driveline configuration, S5 star-profile connection, roll-pin arrangement and protective-guard compatibility. Matching profile and cross dimensions alone do not guarantee compatibility with every driveline assembly. Part 139345 corresponds to genuine Walterscheid OEM 1139345.
