DISASSEMBLY INSTRUCTIONS:

1. Remove the transfer case from your vehicle.

2. Remove the bottom access cover of the Dana 300.

3. Remove the rear yoke.

4. Remove the front index retainer, gear, and input shaft of the Dana 300.

5. Unbolt and remove the tailhousing. With this removed, you should have the output shaft exposed with the tapered
bearing still on the output shaft. This bearing is a tough one to remove. The best way to remove it is by using a bearing
puller. Once the bearing is removed, the stock output shaft can be taken out through the front of the transfer case.

ASSEMBLY INSTRUCTIONS:

1. Remove the new shaft from our tailhousing assembly. Be sure to retain the shim race to set the proper end play. The
pocket bearing should be checked on our new shaft to verify that it has been installed.

3. Once the gear, shaft, and
thrust washer are in place,
install the tapered bearing
onto the shaft. This should
be a light press fit.

2. Install the shaft through the front
of the transfer case, through the
slider hub, and onto the stock gear.
You should make sure you lube the
surface between the gear and shaft.
Install the modified thrust washer
onto the output shaft. This thrust
washer is required to obtain proper
gear and slider alignment with the
other components in the transfer case.

4. Once the bearing is in place, install the speedometer snap ring and blue speedometer gear. Install the shim race provided
in this kit ONLY. This kit's shim race has been matched for this specific output shaft & tailhousing. The shim has
a small internal chamfer which fits up against the shoulder of the shaft. Make sure this is installed properly. A stud
bolt must be installed and locktite into the bottom left tailhousing hole of the transfer case. Make sure the bolt does
not go to far into the case and interfere with the Dana 300 gear. Let the locktite dry before installing the new tailhousing.
As the tailhousing is being installed the 3/8-16 nut must be set into the clearance pocket on our tailhousing and installed
onto the stud bolt as the tailhousing is put onto the Dana 300 case. Install the other 4 bolts to secure the tailhousing
onto the Dana 300 case.

5. A very small amount of RTV blue silicone should be used on the tailhousing mating surface to the Dana 300 case.

6. Reinstall the front retainer assembly onto the Dana 300.

7. Install the 1310 non-C.V. yoke, silicone on the yoke splines and nut.
Torque to 150 ft./lbs.

8. Turn the yoke to make sure the unit is not bound up or is not binding.

Speedometer Calibration: There are two factors that affect your speedometer reading; actual tire diameter and axle gear

ratio. The actual tire diameter is usually different than what is printed on the side wall of your tire. For example: A 33 x 11.5
x 15 tire (depending on the brand), may actually measure 32.5" in diameter. Tire sizes vary greatly among the suppliers. Even
the same tire from the same manufacturer can vary as much as 7% in diameter.

This tailhousing offers a speedometer option (sold separately). This tailhousing is designed to fit a stock Jeep (1983-86)
mechanical driven speedometer housing. Vehicles requiring a cable connection for the speedometer can order P/N

301506. The speedometer gear is not included with this housing, but by using the charts above you can select the correct

gear for your tire size and axle ratio.

If your stock cable does not fit this speedometer housing or if you require additional speedometer connections, then we
recommend that you contact Nevada Speedometer at [phone].
