Removing Oil Guide Housing: Notes

Information 

• The description only applies when installed. 
• If the oil guide housing is removed when the transmission is disconnected, the oil guide housing must be aligned with the aid of a dial gauge (see section on Aligning oil guide housing with a dial gauge). 
• To remove the oil guide housing, it is not necessary to remove the timing case cover. If the timing case cover is removed while carrying out work later, the oil guide housing must also be removed.
