My D6 steering clutch is leaking oil and I would like to replace the oil seals. In a manual they call for using a oil seal retainer tool to remove the oil seal retainer. The manual states to use (oil retained removal tool) part number (8B2893). The picture of the tool in the manual is not very good. Is this a tool that a person can make and if so, how would you go about it. Would you also use the same tool to replace the oil seal. If you can not tell, I really have no ideal where I'm heading with this project. I can use any help that can be provided. Sometime these manuals, assume a person has a lot more knowledge then they do, thanks for your time.
