Installing

Check if the balance shaft can be installed into the cylinder block without forcing it in. If it cannot, the balance shaft must be cooled before installing it.
• Tightening specifications, refer to => [ Balance Shaft Timing Chain Overview ] Balance Shaft Timing Chain Overview.
- Check the installed position of the balance shaft pipe - arrow -:
• The pin on the balance shaft pipe must fit into the groove - arrow -
• Press the pipe slightly together in order to get it into the installed position.
