Post subject:  Seat runner woe

2CV has suffered a minor setback.

After complaints from passenger of a moving passenger seat, I took a look and the front bolt that fixes the outer runner has sheared off flush with the floor.

The bolt screws into a the box section on the floor pan so is going to be a swine to sortout.

Has anyone got any advice? What type of bolt is it? Is it M7? Has anyone sucessfully removed one of these?

Cheers

Matt

I think they visabally poke through the floor. Iirc and they do then put two nuts on and wind out

Matt,
M7, into a captive nut welded just below floor level.

If you have a look, there's another hole in the runner, just behind the front one.
Drill down through the top hat section below and fit a longer bolt (40mm?) with a
spreader washer on the bottom end, until you get hold of an M6 drill and M7 tap
to try and reclaim the original thread.

It should be M7. Usual choices really, if you can, centre dot the middle of the broken stud, drill it 3mm, then 6mm (i think) then re tap the hole., or use an e-z out or similar. I'm a big fan of using heat on rusted broken studs.

Cool I'll try and drill it out this weekend.

Does anyone have a couple of spare M7's I could have for beer tokens?

looking at the bolt it looks quite rusted in there so lucky me is victim of a member of the too tight for copperslip brigade.

Matt,
a common or garden M8 will be OK for the through bolt ( as long as you don't go to B&Q to buy it).
