Fire wall grommet
 

Just wondering......while making repairs to the firewall on a 31 Pick up, I filled the worn out GAV/Choke rod hole as it was quite ragged. I know from experience the repop grommets are not the sized right for the original Ford hole, so I would like to know how large to drill the choke rod hole.
Does anyone know the actual size of the reproduction grommets they are supplying?

this help?

I think the one pictured in Gary's post is the upper grommet for the support under the tank. As I understand it, Ford did not use a grommet in the firewall just one on the choke rod on the engine side of the firewall held in place by a metal cup washer and the spring. See part #14760 in Brattons catalog. If you want to use the non-original grommet supplied in the kit Brattons can probably give you the measurements.

The cup washer and spring also had a small leather washer against the firewall.

you are correct that for the upper bracket! My mistake read it wrong. Age does that Ha.

Isn't Farrell talking about the diameter of the actual hole the choke rod is fitted?

Re: Fire wall grommet
 

Yes, it's the size of the firewall hole I need.

This is the choke rod grommet that came with my kit. I know the leather washer and metal cup washer go in the engine compartment against the spring. However, this grommet is said to go on the firewall (inside?). If that is the case, how it is held against the firewall? Or does it also go on the engine side.....this grommet, leather washer, metal cup washer, then spring.


Sometimes the simplest things get over analyzed.....


On another grommet issue, any tips on how to install the speedometer grommet? I slit the grommet and am struggling to get it installed. I did similar things for the headlight armored cable.

Measure the hole. It may be easier to go to home depot than drill a hole. I forgot to put a choke rod set on my last order. I dug into some drawers and found a grommet that was a perfect fit for the lower and home depot had something to go in the top.


Walkerlakeprinter silicone spray will ease a tough to place grommet. The grommet I used I put on the engine side.

Re: Fire wall grommet
 

I don't think that one goes on the choke rod if you use the leather washer and metal cup.

I have used that type of rubber on my choke rod with a flat washer. I put the rubber part on the firewall side, but don't use the leather or cup washer.

It does go into the riveted plate that the starter rod goes through on a 30-31.

Thanks, I think that it must be for a 1930-31. The kit says it is for 1928-1931, so that would explain it.

walkerlakeprinter that rubber grommet is for the starter switch rod 30-31
