NOTE: Do not overheat (melt) the seal deflector. Monitor the temperature of the deflector with a suitable 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: 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.
Position the deflector on the special tool using silicone brake caliper grease and dielectric compound to retain it to the installer. Using a suitable heat 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).Use Special Service Tool: 205-346 (T95T-1175-C) Installer, Front Axle Bushing., 205-153 (T80T-4000-W) Handle.
