Overview
The Eaton K-D35-200 is a rear master differential install kit for the Dana 35. It includes the bearings and components needed to install an Eaton differential or replace the ring and pinion, all in one box.
Eaton says master kits make a differential upgrade easier because the parts are gathered together. The kit uses premium bearings and components, which Eaton says ensure long life and quiet operation.
Key features
- Master kit with bearings for a Dana 35 rear differential
- Covers all components needed to install an Eaton differential
- Covers all components needed to replace the ring and pinion
- Premium bearings and components, per Eaton
Ring and pinion setup
A master kit is most useful when the ring and pinion are being replaced, because the gear set, pinion bearings and carrier components all have to match. Pinion depth and bearing preload control how the teeth mesh and how long they last. Even a small mismatch can lead to noise, heat or early wear, so the setup should be checked after assembly rather than assumed correct.
Work in a clean area and keep bearings and gears free of grit. Old pinion seals, crush sleeves and gaskets should be replaced rather than reused, and the housing should be cleaned of old gasket material before reassembly. After the first drive, check for leaks, unusual noise and warm housings, and recheck the fluid level once the gears have settled.
- Use new seals and gaskets
- Check the gear pattern after assembly
- Recheck fluid level after the first drive
