CAUTION:
To prevent severe damage to the crankshaft Damper Installer, thoroughly clean the damper bore and the crankshaft nose before installing damper.
Position the damper on the crankshaft.
CAUTION:
The Damper Installer is assembled in a specific sequence. Failure to assemble this tool in this sequence may result in tool failure and severe damage to either the tool or the crankshaft.
Assemble the Damper Installer (special tool #10387, Installer, Vibration Damper) (2) as follows:
1. Install the nut onto the threaded shaft.
2. Install the roller bearing onto the threaded shaft making sure the hardened bearing surface is facing the nut.
3. Install the pressing cup (2) from the A/C Hub Installer (special tool #6871, Installer, A/C Hub) onto the threaded shaft.
4. Coat the threaded shaft with MOPAR® Nickel Anti-Seize or equivalent.
