Volvo Rear Cam Seal Drift (9995450)

General

Pressing in camshaft seals can be challenging and if not pressed to the right depth or pressed in crooked, they will leak. Volvo used to make a special tool (9995450 or 999 5450), but it is hard to get and if you can get it, it's very expensive.

I took measurements on the actual cylinder head to reverse engineer the dimensions of the tool, since I did not have one either. This tool will press in the cam seal to the right depth and ensure it sits straight.

Versions of the Installation Tool

• Flush: The seal has to be installed flush with the housing according to the official instructions. This is achieved with this variant
• +1mm: If there is an excessive wear groove in the cam, the workshop manual states that you can drive the seal up to 2mm further in to avoid the new seal running in the old groove. This is an intermediate step between flush and +2mm.
• +2mm: Maximum depth allowed according to the workshop manual.

Print Settings

• I used PLA, other polymers will probably work as well (as long as they are hard)
• ≥50% Infill for maximum strength
• ≥3 perimeters recommended
• 0.1mm layer height to ensure dimensional accuracy
• The 7mm hole for the bolt can be tight, you might have to drill it out or run the screw through it a couple of times

Additional Hardware

• You can reuse the original bolt for pressing in the seal.

Disclaimer

When using printed/plastic tools for pressing, there is the possibility that they will shatter or break etc. Be responsible when using the tool and wear appropriate protection. I'm not responsible for any damage or injuries.

It took quite a lot of time to make this tool, so if you're a tool company and want to make a fortune with the tools, perhaps send me some money for filament 😅
