Intermediate Shaft Seal and Deflector: Installation
| Item | Description |
|---|---|
| 1 | Intermediate shaft seal (part of 7275 kit) - retains red automatic transmission fluid used in the transmission |
| 2 | Alignment washer (part of 7275 kit) - supports and centers the intermediate shaft in the seal |
| 3 | Cover Seal (part of 7275 kit) - keeps dust/dirt away from the intermediate shaft seal |
| 4 | Seal deflector (part of 7275 kit) - keeps dust/dirt away from the PTU input shaft seal |
| 5 | Seal protector (part of 7275 kit) - protects intermediate shaft seal from damage by the intermediate shaft splines during installation. Must be removed before shaft is fully installed |
- 4.NOTE: Do not use force when installing the alignment washer or damage to the washer can occur.
Special Tool(s): Installer, PTU Linkshaft Seal 205-883, Handle, Driver 812.8 mm (32 in) 205-907.
- 5.NOTE: Do not overheat (melt) the seal deflector. Monitor the temperature of the deflector with a temperature measuring device, such as a digital temperature laser or infrared thermometer, while heating. Do not allow the temperature to exceed 100 °C (212 °F). Overheating will damage the deflector. If the deflector is damaged, a new deflector must be used.NOTE: Apply a small amount of silicone brake caliper grease and dielectric compound to the inner lip of the deflector where it installs on the tube inside the PTU before heating. This will ease the installation of the deflector.
Hot air gun. Special Tool(s): Installer, Front Axle Bushing 205-346, Handle, Driver 812.8 mm (32 in) 205-907. Position the deflector on the Installer, Front Axle Bushing 205-346 using silicone brake caliper grease and dielectric compound to retain it to the Installer, Front Axle Bushing 205-346. Using a hot air gun, heat the back of the tool to a minimum of 71 °C (160 °F) and a maximum of 93 °C (200 °F) by concentrating the heat across the back of the installer while rotating the tool. Once the optimum temperature is achieved on the tool, move the heat gun to the front of the tool and heat the inside of the deflector where it snaps onto the PTU shaft until the temperature of the deflector is a minimum of 93 °C (200 °F) to a maximum of 100 °C (212 °F).
- As an alternative method to heating the seal deflector, place the deflector in boiling water for 3 to 5 minutes. Dry off the deflector and install.

General Equipment: 5-Pound Dead Blow Hammer Special tool(s): Installer, Front Axle Bushing 205-346, Handle, Driver 812.8 mm (32 in) 205-907. Install the seal deflector immediately after heating.
- 7.
Make sure the deflector is completely seated all the way around and there are no cracks on the face. The deflector is correctly installed when the face of the deflector is recessed 3-5 mm (0.12-0.20 in) into the pocket all the way around.
- 8.NOTE: A significant amount of residual fluid will collect between the seal and deflector during this repair. This is a normal condition and should not be misinterpreted as a leak after the repair is complete.
Using metal brake parts cleaner, thoroughly clean the deflector and intermediate shaft area of any residual fluid that may have accumulated during the repair.
