Vespa special tools for oldies

For lovers of the elderly Vespa models up to the GS series or even Wideframes called, we have a nice one Vespa special tools from bgm PRO included in our program.

Main shaft bearing stuck?

Many screw connections on the older Vespa ladies are due to aging, lack of maintenance and standing around forever rotten and sometimes only to be solved with a few deep handles in the bag of tricks.

The end shield for the center mainshaft bearing is one of these cases. The face hole threaded ring made of bare steel had in many cases for decades to establish an intimate connection with the aluminum of the motor housing with the help of acidic, old oil and water.

Our safe special solution

A loosening of this brazen connection sometimes seems impossible. A simple face spanner tends to slip in these cases. We have therefore “built in” the possibility of preloading in our tool.

The key is held under pretension on the threaded ring by the bolt that is supported at the end of the bearing lane of the main shaft. So that can safely reached the breakaway torque required to loosen the nut without the face wrench slipping off.

Even with a very stiff thread, the threaded ring can be loosened without damage. Because the key in the guide has the same thread pitch as the face hole ring, the tool follows the loosening ring with the same preload. It is therefore impossible for the key to slip off.

The tool offers the possibility to use both known wrench sizes of the threaded rings.

Hole stitch of the forehead holes 37 mm suitable for the threaded ring with 28 mm Inner diameter
Hole stitch of the forehead holes 43 mm suitable for the threaded ring with 35mm inner diameter

The tool is driven over the wrench sizes SW22 and SW17. The hard threaded pins are easy to distinguish over their length.
The large pin (L = 25mm) operates the threaded ring with the large inner diameter and the small threaded pin the threaded ring with the small diameter.

Both pens are also available as spare parts just in case.

Depending on which threaded ring is to be loosened, the threaded pins that are not required can simply be “retracted” into the tool.
