Guys,

I'm looking for information on the band that is bolted to the locking spare tire cover and heads south. All I have is the piece that bolts to the cover. My understanding is that I'm missing some other piece. I'm not sure what that piece looks like or where it bolts to. Does it bolt to the spare tire support casting somehow? Anyone have the piece I need laying around?

Thanks much,

Peder

Peder, Here is a sketch of the band. It attaches to the bottom lug of the rear spare tire stand/support.

It looks like this..... not sure if there is a difference between years on the strap, but I doubt it. This may be bent a little.

it uses a twist off type bolt where once you tighten it the hex breaks off leaving a domed head like the one on the back of the lock (like a stove bolt with no slot) There should be a threaded hole on your spare tire rack.

As Don mentioned, it slips over to the spare tire support bottom stud for the mounting of the spare tire rim and is held in place with a thin hex check nut on the stud. there is no twist off bolt in this area.

I was gettihng ready to post the same information. This strap is mounted to spare tire carrier on my cars the same way you and Don described. Also, it seems likely to me that straps would differ on different years based on different tire sizes.

I stand corrected.... I should stick to posting photo's....

Thanks guys, now I just need to find one.

I would suggest putting an ad in the swap wanted section here and on the Early Ford V8 Club website. Also keep an eye on eBay. You may even have to buy the whole assembly just to get the piece you need and then resell what you don't need.

jim1932 · 11-11-2011, 10:29 PM

So anyone know the measurements for the various years?

jim1932 · 11-19-2011, 05:26 PM

Not to hijack the thread, but I thought it was similar interest. Is this hub put together right? Is something bent? Just looks odd, and I never paid that much attention when I took it off.

I've run across the Ford Archives engineering drawings and release forms for both the 40-prefix and 48-prefix spare wheel and tire lock bands used with the locking hubcaps on '33-'34 and '35 passenger car rear-mounted spares and they are very informative (for those interested in such modest subjects). The part numbers were 40-18307 and 48-18307 for the long hook-shaped bands and 40-18308 and 48-18308 for the short bands that attached to the locking hubcaps.

In each case, the 48-prefix bands are very similar to the 40-prefix bands. So similar in fact that Ford designated the 40-prefix bands obsolete at the end of October, 1934 when the 48-prefix bands were released. In other words, the 48-prefix bands replaced the 40-prefix bands for service for '33-'34 rear-mounted spares as soon as the existing inventory of the 40-prefix bands was exhausted.

While they are very similar, there are enough differences that both the short and long bands of each version can be differentiated visually. On the long bands, the 40-prefix version has a much tighter (nearly 90 degree) bend immediately below where it attaches to the spare wheel bracket on the body compared to a more open bend (about 60 degrees) at that point on the 48-prefix long band. On the shorts bands, the radius of the curve in the 40-prefix band is 5 inches compared to a shallower radius of 10 1/2 inches in the bend of the 48-prefix band.

Judging from Jim's photo immediately above, both his bands are the 40-prefix variety.

Unbeknownst to me previously, bands for the '32 locking hub caps were released at the same time as the locking hub caps (mid-May, 1932, much earlier than previously thought). They were numbered B-18307-B (long) and B-18307-B (short); the "B" suffix served to differentiate these parts from those used in the B-18305-A spare tire and wheel lock assembly released earlier in the 1932 model year that was independent of the hub cap.

Judging from the engineering drawing (I've never seen a surviving example of these '32 bands), the general appearance of these bands is the same as the 40-prefix and 48-prefix bands, but they are unique enough to easily differentiate them from the later versions. On the long band, there are no little kinks in the large curvature of the "hook" and the straight portion of the shank of the hook is noticeably longer than on the later versions. It is approximately 12 7/8 inches in height from top to bottom (curiously 1/8 inch shorter than the 40-prefix long band, but an 1/8 inch longer than the 48-prefix long band). The '32 short band is 10 29/32 inches long compared to 10 inches for the 40-prefix short band and 9 3/4 inches for the 48-prefix short band. The curve in the center of the '32 band has a radius of just 2 1/2 inches, making it the tightest curve in the center of any of the three. This makes its straight section noticeably longer than the 40- and 48- prefix versions.

The drawings are full scale, so I will obtain reduced-size copies and include the '32 bands in the next round of "Additions and Corrections" to the 1932 Ford book on the V-8 Club's website.
