How do I go about undoing the bearing carrier on the Appia back axle without damaging it ?

I suspect that there was a special tool "chez Lancia" . The size across the flats is 98mm

Any suggestions ?

Thanks

Have you asked Don Cross. Maybe something in the Appia Consortium?

Is there a "special tool book" for the Appia on one of the CDs?

Unfortunately standard Appia is about 78 mm not 98 as on the van,  apparently the nut is v tight so the chain wrench is unlikely to work, but always worth a try !

I think that I will have to try making a tool, anyone any experience of cutting steel to make a spanner ?

Normally spanners are forged to get their strength. May be machine from 100mm tool steel bar to keep the tube and strength.

Is that just two flats there Simon, I am not sure quite what I am meant to be looking at?

We have successfully made spanners from 6 or 8mm flat. Cut out the two faces at 98mm, keep it as a closed item ie cut a square out of the flat, rather than open ended. The other (easier) way to achieve this, is to cut it as an open ended spanner, but then weld a piece across the open end to give it that extra strength.

Another thought, we have done this as well, is to use a piece of suitably sized piece of square or rectangular hollow section. Cut, say a 100mm length, weld a 'cheek' in to produce the required 98mm across the flats and either weld a bar across the end or onto one side to act as the lever or drill holes in opposite faces through which to pass a bar as the lever.

Good luck however you choose to attack this!!!!

Whatever you do, try and introduce plenty of heat. Heat is a very undervalued tool in the workshop and can save a lot of heartache. Also try to ascertain whether it's LH or RH thread!
