Seat slides backward, seat adjustment Options

[Mike1981]

Hello

I just picked up a 1970 914
I was hoping for some advice please

I seems as if the clutch pedal must be depressed all the way to the floor to avoid grinding

However the seat is all the way back to the firewall

When I move the seat forward my legs can easily depress the pedal as well as the reach to the gearshifter is better.

The only problem I have is when pushing in on the clutch the seat detaches from its setting and slides all the way back

I took the seat out oiled the rails and it slides easily by hand

Once I put pressure on it, the seat will again snap out of it setting and slide back

Has anyone had this happen

Could anyone offer a solution?

Thanks

Mike

Just one random idea for the clutch:

You may also want to check to see if the clutch cable tube is coming loose from its welds. It runs through the center tunnel underneath the gear shift and back through the firewall. It's welded in two places to secure it in the tunnel (I believe) and one where it exits the firewall. When mine was giving way (one of the welds broke and eventually the sheet metal at the firewall cracked) I noticed I had to depress the clutch further to the floor. It's a common problem on these cars. When the last weld gives, you'll suddenly have no clutch. I agree the first check is the cable, but if that feels like it has no more than the required slack then I would look at the tube.

One way to easily check is to remove the carpet on the tunnel and lift out the access panel between the seats near the rear firewall. You can also remove the gear shift plate to see if that gives you a good view into the tunnel. Push the clutch while looking into the tunnel. You may see a tube move slightly. That's the clutch tube. If it moves "significantly" when you depress the clutch it's likely one or more of the anchor welds has failed. If that's the case, repair it before you're left high and dry somewhere.

Good luck, Mike.
