Installing Crankshaft Sealing Ring For Pulley/Vibration Balancer

Information 

Sealing rings become damaged as a result of improper fitting. Do not oil sealing rings on the running surface and do not pull sealing rings off the plastic sleeve.

Information 

• If the joint flange on the pulley or the surface on the crankshaft stub is slightly rusted, polish the rust off with a special polishing pad. 
• If there is bad corrosion or deep grooves, replace these components.
