What's the deal with the front of this steering wheel?
 
2 Attachment(s)
Here are images of the front of two different steering wheels. The first image is of the wheel off my 71. My other two wheels are the same.

The second image is of a wheel I recently purchased. Why is it different, were there two different types? Is it missing the piece per the top image, and does the piece pop off somehow?

All four wheels have the same stamp 9749753

I suspect the wheel in image two is just missing the rim. If so, I'd like to pull one off my other wheel. I took a knife to the perimeter of the rim, but it still doesn't budge. I believe I need to be drilled out where shown in this image. Anyone?

Reason I bought the wheel to begin with (2nd image). Grain looks super or close

Can't for the life of me understand why the "new" steering wheel (Image 2 in OP) doesn't have a rim on the front center. Perhaps it was broke and they removed it. I'm hoping someone knows what's up and can clue me in on what to do. I haven't fully committed to the steering wheel yet, I have to very soon. I'd like to own it, though would also like to know what I'm getting into. The wheel is NOT cheap. For all I know it's toast.

Well I found out it's a dust shield for the turn signal. They're likely attached using molded plastic. The seller thinks he has an extra. Otherwise I steal one off another. Any ideas how to mount one appreciated. I bought the wheel. Pretty expensive man, but the project warrants it, so WTH. I've only seen 1-2 available with this grain, early take-off

Oops. You are right. I’ve never seen that component missing and haven’t a clue as to how to reattach one. Maybe I’m wrong but something looks different about the finish on that wheel - this and the black color on the hub make me think it’s been painted and therefore possibly repaired.

I should be able to tell after I get it. Any signs of repair/paint it's going back. I think you're right about the hub though. I don't think they're painted from factory, though I've seen more with paint than w/o. By the pic. there doesn't appear to be any rust. See what happens.

Incidentally, I believe that wheel just needs to be polished. I bought another some time ago, and unlike the one I pulled off the truck it was dull like this new one. Made me wonder if painted. I sanded it down to I believe 3000 grit, still somewhat dull. Word is white rouge compound and a soft flannel buff are in order in these cases. I just did a half job on a spoke, and the finish is the same as my old one.

These wheels were used in Vans through '78. It could be they changed molds or it's a different jobber at some point post-72

It appears to me that the later (van?) wheels had a somewhat different grain on the rim portion of the wheel. The grain on my original appears "finer"/ sharper than the later wheels. Has anyone else noticed this? Is it just difference in wear? Here are closeups of mine which was covered most of its life.

Could be, but in this case the wheel is simply missing the dust rim. So I get to learn something new I guess.

I agree, there does appear to be some differences in grain. Hard to tell, but the grain on this NOS appears less "fine/sharp" than yours. http://67-72chevytrucks.com/vboard/s...d.php?t=656232

This is absolutely the case. I’ll post a grain pic when possible of a later example. The diameter on the later wheel I have feels larger than the earlier wheel though I’ve not measured either.

Re: What's the deal with the front of this steering wheel?
 
I have a hard time believing the van business, though not saying you're wrong either. The grain on my original wheel looks nothing like the fine grain on Jim's wheel. Most wheels I've seen don't, worn or otherwise. Granted the top of my wheel is warn out, but there's no apparent wear along most of the spokes. Doesn't mean the wheel wasn't replaced at some point, but knowing the history, I don't know why the old man would have pre-1989. Could be the spokes wear out easily too, though I don't know why they would.

Jim's wheel preceded my 71, both likely have the same original casting # (9749753). Perhaps there were variances in molds both before and after 1971ish. That or I don't have a clue, which I really don't;)

Be nice to see more examples of Jim's wheel, and what years they come from. Everything I have is like post #14, and two are mostly smooth on top from wear.

Re: What's the deal with the front of this steering wheel?
 
My wheel (part # 9749753) is the original from the factory unless the dealer had some reason to change it in the months between production and when I bought the truck new in 1969. I put a leather cover on the wheel about 1972 when the truck had less than 25,000 miles. I removed the cover in 2010 at 118,713 miles when I started the restoration. I have looked at the grain many times and wondered what it would look like worn to a level similar to the "good" ones we normally see. Perhaps it would look the same as the others. Obviously, as mentioned above, more than one grain type could have been used with the same part number, but why would mine be unique other than it has very little wear?

That said, I have a spare tilt I rescued from a van that has the part #335212 wheel. I don't recall the year that the van was, but it must have been early 70s since the tilt has a metal gear indicator housing, a truck type indicator lens (both supposedly used only on truck tilts) and a curved wiring connector. That wheel has a pattern similar to what we normally see. I have another wheel which I believe came from my junkyard truck tilt that I will have access to in a couple days. I'll check the part number and post it here.

EDIT: Here's a link to a wheel sold here that both Tony and Pete responded to. It looks to me that my wheel might display this pattern if worn. It also may look like Tony's in post 2.

That piece (dust shield) is attached with molded plastic, perhaps glue as well. They probably probably broke it.

I have my new wheel and "spare" dust cover sitting in a box. I'll show you guys what it looks like when I get to it.

I wondered that too, is it possible all the grains were like yours at some point, and wear caused them to appear as a different grain? But I don't think so, the valleys seem much longer in the "later grain".

If there are two different grains, I'm not so sure it's as simple as "69-72" grain Vs "later van" grain. Might be a 69-70 grain Vs later grain, just guessing here.

Nope, not a clue. I had to grind some of the surrounding area down some, so a dust shield fits flat. No sign a a rust issue anywhere.

"Someone" knows something we don't about these wheels. That or what are the chances there are two early take off wheels missing their dust shield? This is not who I bought the wheel from, but I do see some irony: https://www.ebay.com/itm/1969-1972-O...e/323873411100

The new wheel and the original. You can barely make out the part number on the new one, needs a good polish.

I agree. This other wheel has a major crack (about 1/4" wide) at the top of the hub. I tried to pry it apart with no luck. That dust shield seems molded in. There is zero grain left on the rim. Tony, if you want this wheel for practice, it's yours!

There's absolutely some plastic molding to it. See post 29 (revised) for how I think they're assembled, (edit: Which was wrong, I deleted the post:lol:).

Nice gesture, thanks Jim, but unless that steering wheel is toast I can't do it. You might be surprised what these are going for now, check Ebay, I think there's one available. Imagine that, 69-72 wheels are now rare. I see some trying to sell complete junk for 200ish. Course they're worth $1, but WTH. Just guessing here, but I feel I can sell my old one for $150+, with cracks and major grain loss. Otherwise I'd pull its shield.

Not sure I can pull a shield successfully, but I think so. Heat it up and see where to pry. Drill more spots if I have to, see what happens. If I take my time, I figure success rate is 80/20;). Perhaps their engineering comes in my favor, the only tension on these is vibration.

I forgot to mention, I think I read you can tell part 335212 by the hub, which is missing the 5/16" threaded holes, at least. I believe they all have the later grain. All my wheels have the 9749753 imprint. The # doesn't come up in the parts book, but the replacement (335212) does.

I tested some acetone on my old wheel, which is pretty brilliant as is, and I'm going to say acetone is for last resort. And NEVER on the part number or grain. While it cuts through the muck and perhaps scratches too, you end up having to sand and polish afterwards.

As chemicals go, so far 3M plastic polish and rag works best. At some point I'd like to try white rough & flannel buff like Jim suggests. Tried that once, but I didn't expect the white rough to be hard, thought it dried up:lol:

Upon further thought & reading, I think that "haze" as I called it is plain 50 years of film. Possibly environment related as well, because like I say, the finish on my old wheel is real good, but I never so much as cleaned it in 25 years.

I've seen those prices, but with the hub crack and 6 smaller cracks, I think it's beyond repair and not worth the hassle of selling it. Besides, it was on my true truck tilt column when I found it in the junkyard. I paid a total of $50 for the column and wheel. I think I came out pretty well. Here are some pics. The offer still stands if you change your mind.

I'm going to try my hand at recasting a couple wheels. Mainly because I'm stuck on the odd ball 69 colors.
I have a couple old pieces and figure ill make the mold with an nos wheel then break all the plastic off the donor and see if I can get it to work.
This thread got me thinking that shield was maybe glued in afterwards.maybe a two part deal. Ill probably sacrifice the dark green first. The hope is that the color in the center of the plastic is accurate. Anyways...
It's threads like this that inform me and guide forward momentum. Thanks guys!
Of course being armed with information just makes me more dangerous. Lol

It is a two part deal for sure. That said, it could have been by the same hand, who knows. Molded plastic is dripped into the holes in the shield. The plastic appears to be the same as what forms the wheel. I think the shield is glued in four spots as well, per the indicators. That or they used molded plastic for those spots too.

Re: What's the deal with the front of this steering wheel?
 
I believe the process was to place the dust cap over the plastic studs on the wheel then hot melt (stake) those studs tight. The process might be called sonic welding.

Be nice if that's all, I'll find out when I pull one. There may be one stud only. It's that or one is shorter than the other. The wheel I'm working on only has one, and I can only make out one on my other wheels. If you have a wheel handy I suspect you'll only see one as well. Both holes in the shield are filled, what you reference as sonic welding.

More info, 335212 vs. 9749753:
My 335212 wheel (pics 1 and 2) does have the threaded holes for a puller, but they do not go all the way through the hub. I was successful at getting the dust shield off the 335212 wheel. It was held on at 4 points by some sort of adhesive that's still slightly tacky and a melted plastic stub at the 12:00 position.

I also took a better look at my original 9749753 wheel. It appears to have 4 melt marks that are circled in the 3rd picture.
