Tip Corner:

If you choose to replace your drive seal without disassembling pump completely here is a few tips.

1. Using a medium screw driver and bench grinder create a tool similar to the one picture below. The orange lines show the screw driver shape before grinding.
2. Using a hammer gently tap the screw driver between the rubber part of the seal and the pump drive shaft. Care must be used to avoid damaging the main pump aluminum Housing. (Picture A)
3. Gently push the screw driver down thus prying up on the seal. If the seal appears to be to be bending instead of pulling out you may need to tap it slightly again or move the screw driver to a new position and try from there. You may have to pry from several sides before the seal will be removed (Picture B)
4. With some luck you will have the results found in (Picture C)
5. Clean seal area. Lubricate both inside and outside areas of the new seal. Using the hammer gently tap the seal in with a perfect sized deep well socket. Seal needs to be kept level as it enters the pump. (Picture D)

Please Note: Your fuel injection pump is a very technical devise. Not only does it control your engine it also protects it as well. Repairing your pump yourself is a great way to save money. However, extra care must be used as serious pump and or engine damage can occur. A person repairing their own injection  pump is assuming their own risk.
