Walterscheid | PTO Inner Guard Half STH25Z 1500 mm | W2300–W2500 | 113781
Walterscheid 113781 is a genuine STH25Z inner PTO guard half, OEM 1113781, designed for compatible W2300, W2400 and W2500 standard PTO drivelines. This is a complete inner guard-half assembly, not just the yellow plastic guard tube, and includes the support, bearing and retention components required for the compatible 25Z guard system.
The guard half has a published 1500 mm tube length, 185 mm guard-cone diameter (D) and an RP7 guard cone. The profiled STH25Z guard tube is designed to telescope with the corresponding outer guard half while helping prevent the two protective halves from rotating independently.
The assembly includes the 355155 red SC25Z support ring, 158845 green support ring, 087276 SC25 guard bearing / slide ring, 044321 retaining chain and 365305 guard-cone screw. These components are supplied as part of the complete inner guard-half assembly and work together to support, locate and retain the protective guard around the PTO driveline.
Before ordering, verify the original Walterscheid OEM number, STH25Z guard type, 1500 mm length, 185 mm cone diameter and the matching outer guard configuration. Driveline family alone does not guarantee fit because Walterscheid offers different guard lengths, cone styles and 25Z configurations within the same W2300–W2500 families. Part 113781 corresponds to genuine Walterscheid OEM 1113781.
