Installation Procedure

1.

NOTE: Care must be taken when installing the O-ring correctly. Ensure it is not twisted or distorted and is properly seated in the correct machined groove of the power transfer unit.

O-Ring(2)@Power Transfer Unit Output Shaft - Install NEW.

NOTE: Walk on the retaining ring to avoid distortion.

2. Retaining Ring(1)@Differential Carrier Assembly - Install NEW.

3.

NOTE: Care must be taken when installing the O-ring correctly. Ensure it is not twisted or distorted and is sitting properly seated in the correct machined groove of the differential carrier assembly.

O-Ring(2)@Differential Carrier Assembly - Install NEW.

NOTE: Walk on the retaining ring to avoid distortion.

4. Retaining Ring(1)@Differential Carrier Assembly - Install NEW.

5.

NOTE: Install the front propeller shaft to the power transfer unit referencing the marks. When the propeller shaft is correctly installed an audible click can be heard from the c-clip. Then ensure that front shaft is fully engaged by firmly pulling on the front tube. Then install the rear by aligning the reference marks and ensure that the rear shaft is fully engaged into the differential carrier assembly, again by listening for an audible click and then by firmly pulling on the rear tube. Do not use leverage to seat or when checking to see if fully seated.

Propeller Shaft(1) - Install.

6.

Install the front of the propeller shaft (1) to the power transfer unit referencing the marks. When the shaft is correctly installed an audible click can be heard from the retaining ring (2). Ensure that the shaft is fully engaged by firmly pulling on the front tube. Do not use leverage to seat or when checking to see if fully seated.

7.

Install the rear of the propeller shaft (1) by aligning the reference marks and ensure that the rear of the shaft is fully engaged into the differential carrier assembly. Listen for an audible click from the retaining ring (2) for proper installation. Ensure that the shaft is fully engaged by firmly pulling on the rear tube. Do not use leverage to seat or when checking to see if fully seated.

8. Prepare the bolts for installation as follows:

1. Remove all traces of the adhesive patch from the bolts and the mating threads using the appropriate tools.
2. Clean the threads of the bolts and mating threads with denatured alcohol or equivalent and allow to dry.
3. Apply thread locking adhesive to the bolts. Adhesives, Fluids, Lubricants, and Sealers

12. Conduct a retention check on the propeller shaft front and rear interface. Place hands around the propeller shaft tube just behind the interface and firmly pull on the propeller shaft tube without using leverage or body weight. The intention is to check that the snap ring has snapped into position, not to forcefully remove a correctly installed propeller shaft. Verify the O-ring is still seated in the groove and the paint marks are aligned correctly.
