Preloads New earings 8-12 lb. in. ( N m) ** Used earings* 5-8 lb. in. (.6-.9 N m) ** Drive Shaft 3-5 lb. in. ( N m) * earing is considered used if spun under load even once ( under load meaning: with power applied ). **Plus drive shaft preload [3-5 lb. in. (.3-.6 N m)] Example: Drive Shaft Preload 3 lb. in.

10 Driven Gear Shimming (With Load Ring) NOTE: ravo One drives with serial numbers OD and higher use a load ring instead of shims. 1. Install the load ring (a), thrust ring (b), and o-ring into the gear case. 3. Tighten the retainer to the proper preload using the following procedure. a. Tighten the retainer in small increments. a - earing Carrier Retainer Wrench ( ) b. After tightening, check overall gear housing bearing preload at propeller shaft, each time a - Load Ring b - Thrust Ring (.105 Thickness) c - O-ring d - Propeller Shaft 2. Install the later style bearing carrier (41641A8) (a), tab washer (b) in the gear case. a - Lb. In. Torque Wrench ( ) b - Propeller Nut (under socket) c - Rotate Shaft in Direction of Normal Rotation Using a Smooth, Steady Motion c. If you tighten the retainer past the overall preload, replace the thrust ring and start again a - earing Carrier b - Tab Washer c - Inner Tab - Position in V-notch d - Outer Tab 3C-8 - RAVO ONE
