General

Pressing in the subframe bushings (e.g. 3507923, 3507924) into Volvo P80/P2 subframes is challenging, because they sit very tight, have to be oriented correctly and when pressing on the rubber “crown” or the inside part of the bushing, you will probably damage it.

Volvo makes a special tool for it with the part number 9995457-1, 9995457-4 9995567-2, 9995589-65 which is not available anymore and there is not really an aftermarket alternative.

This is where this tool comes in handy, as it will distribute the force on the plastic and not on the rubber crown and therefore allows to install the bushing without damaging it. Depending on your bearings, they might still be too tight to install them just with the tool. In my case, it was required to apply a lot of preload with the tool and send it home with a rubber mallet.

The cup is required to leave space on the upper side of the subframe since the subframe bushings stand a little proud of the subframe and you don't want to squish the rubber either.

The tool is tested with the SKF VKDS 872002 bushings, but it should fit any other brand as well. It can be used to press in the PU subframe inserts as well.

Versions of the Installation Tool

• With Centering Pin: The centering pin helps to align the tool and keep it aligned while pressing the subframe busing in.
• Without Centering Pin: This is a fallback in case the tool doesn't fit your subframe bushing.

Versions of the Cup

• Long: This is the cup shown in the pictures. It is longer than necessary as it had a second purpose.
• Short: The shorter cup makes the alignment a lot easier, so this is the preferred version to be used. Saves some filament as well.

Print Settings

• I used PLA, other polymers will probably work as well
• ≥90% Infill for maximum strength

Additional Hardware

• Very long M14 screw or M14 threaded rod
• 3x M14 Nuts
• 2x M14 Washers (the biggest you can find to spread the load on the tool)
• Some high pressure lithium grease to grease the rod
• Wheel Bearing Kit for the cup with the 81mm tool (see last picture)

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.

Please consider liking and posting a make if you find this useful 🙂
It took a lot of filament to print the prototypes, so if you're a tool company and want to make a fortune with the tools, perhaps send me some money for filament 😅
