Neapco 1-1001 Walterscheid 2100 Series Universal Joint
The Neapco 1-1001 Universal Joint is a greaseable metric U-joint designed for Walterscheid 2100 Series PTO and driveline applications. Built for reliable torque transfer and smooth articulation, the 1-1001 is well suited for agricultural, industrial, vocational, and power take-off driveline systems where this compact metric joint configuration is specified.
Neapco identifies the 1-1001 as an outside-snap-ring (OSR) universal joint with round bearing caps. It uses a grease fitting located in the cross, allowing periodic lubrication to help protect the needle bearings and extend service life in demanding operating environments. Neapco’s dimensional catalog lists the joint with 0.866-inch bearing caps and a 2.157-inch lock-up dimension on both axes.

Fitment Note
Universal joints can appear nearly identical while differing by only a few thousandths of an inch in cap diameter or lock-up dimension. Before ordering, confirm the 0.866-inch bearing-cap diameter, 2.157-inch lock-up dimension, outside-snap-ring configuration, and Walterscheid 2100 Series application. The Neapco 1-1001 is a direct aftermarket alternative to the Dana Spicer 5-3233X for compatible Walterscheid 2100 Series PTO and driveline assemblies.
