Step 6. Using Soft Metal (Brass or Aluminum) Pin Strike both ends of Shaft with a hammer and recheck the Bearing Pre-Load, This is to ensure Bearings and components are centered and seated. If Bearing Pre-Load is OK insert Cotter Pin (item # 11) and Bend ends.

Step 7. Output Seal, Put a light coat of Grease on ID of Seal or on OD of shaft where Seal rides. Install the Output Seal using a Seal Driver.

INPUT SHAFT REMOVAL

Step 1. Install Inner Bearing Cup (item # 12) into back of main Housing (item # 1), Make sure Cup is seated into Main Housing.

Step 2. Install Outer Bearing Cup (item # 12) into back of Front Bearing Cover (item # 24). Make sure Cup is Seated into front Cover.

Step 3. Install Spacer (item # 13) onto Back side of Input Shaft (item # 26), Install Spacer (item # 28) onto input Shaft (item # 26) from the front. Install Shims (item # 29,30 & 31) onto input Shaft from the front. For quantity of Shims refer to how many were removed.

Step 4. Install Input Gear (item #27) on to Input Shaft From, Install Outer Bearing Cone (item # 12) on to input shaft and slide down till it seats against Gear. Install Inner Bearing Cone (item # 12) Onto input shaft.

Step 5. Slide Input Shaft with all components down into Main Housing till Inner Bearing Cone is seated into Inner Bearing Cup. Look at Input Gear and Output at this time, Input Gear should not be held up by Outer Gear, if it is it will be required to add Shims (item # 29,30 & 31). If Input Gear and Output Gear Seem to far away from each other remove some Shims (item # 29,30 & 31).

Step 6. Input Seal (item # 25) can be installed now or wait till later. With Shims (item # 20,21 & 22) lower Input Bearing Cap (item # 24) down over Input Shaft. Install Bolts (item # 23) into Bearing Cap and tighten them, Check Bearing Pre-Load and Gear Back Lash. Bearing Preload should be from 12 to 14 pounds of Rolling Torque, Gear Back Lash should be from .016" to .021". If these are not, shims will have to be removed or added to get these readings.

Step 7. Install Top Cover (Item # 18) and Gasket (item # 19), Install Pressure Vent Plug (item # 16) with Sealing Washer (item # 17), Vent Plug must be 5 pounds pressure relief type.

Step 8. Fill Gearbox with Oil, remove Oil Level Plug (item # not shown) on side of Main Housing, Remove the vent Plug (item # 16) and fill with oil till oil starts to seep out of Oil Level Plug, Stop and wait about 20 minutes so oil will have time to seep down around Output Shaft bearings then finish filling with oil, This procedure may take longeer on Cold days or Shorter on Hot days. Always recheck Oil Level after gearbox has been run approximately 1/2 hour.
