Installation

Note: Be sure to replace the front crankshaft oil seal with a new one after each removal.

Caution: To ensure proper sealing, contact surfaces must be clean, dry and free of grease (avoid any fingerprints).

1. Using a cleaning agent, clean and degrease the contact surfaces of the crankshaft with the front oil seal, as well as the seat for the front crankshaft oil seal.

Note:

• This type of seal is very fragile, so a special tool must be used to install it.
• To prevent leaks after installation, only the protective element (7) may be touched when installing the seal. Touching the seal itself (8) is strictly prohibited.

2. Insert the threaded rod (9) of the oil seal press tool (Mot. 1586) into the crankshaft.
