OUTPUT SHAFT INSTALLATION

Step 1. Install Upper Output Shaft Bearing Cup (item # 12) into Main Housing from the top, Install Output

Shaft Lower Bearing Cup (item # 2) into Main Housing (item # 1) from the bottom, Make sure both

Bearing Cup are seated firmly against housing.

Step 2. Install Lower Bearing Cone (item #2) down over Output Shaft from top making sure it is

completely seated against shoulder on lower part of Output Shaft.

Step 3. Insert Output Shaft (item # 8) into Main Housing from the bottom till Lower Bearing Cone is

seated into Lower Bearing Cup, Slide Upper Bearing Cone down over Output Shaft from the

till it seats down against and into upper output Shaft Bearing Cup.

Step 4. Slide Output Gear (item # 9) down over Output Shaft till it sits against upper Bearing Cone.

Step 5. Install Output Shaft Bearing Adjusting nut (item # 10) Tighten Nut to set Pre-Load on Output

Shaft Bearings. Bearing Preload should be from 12 to 14 inch pounds of Rolling Torque.

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. To Install the 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 INSTALLATION

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 Step 7. on Input Shaft Removal.

Step 4. Install Input Gear (item #27) on to Input Shaft from the front, 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

intoInner 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 longer on Cold days or Shorter on Hot days. Always

recheck Oil Level after gearbox has been run approximately 1/2 hour.
