a wheel question for 1 ton dually owners - The 1947 - Present Chevrolet & GMC Truck Message Board Network

63 & 64 Bowties · 08-22-2009, 03:06 PM

I've got a 69 farm use dump truck.... this one:
(yea, I know. I'm gonna fix it up one of these days, honest)

And, I bought a 92 3500 a while back for the engine/trans for my 53 AD.
I was hoping to use the 92's wheels/tires for my 69 dump truck.
I started to do the swap yesterday, then I find out the 92 has bigger wheel studs than the 69. I would imagine the bolt pattern is the same (I haven't checked yet.) But, can I use the 69 lug nuts and bolt up the 92 wheels on the 69? Anyone done this?
I really want to get rid of those split ring rims.
My other dilemma is that I wanted to put 4 of the 69 rims on the 92 to make it a roller, but I guess the only way to do that is to drill out the 69 rims, they're junk anyway.
Any advise would be appreciated.

sailed2japan · 08-22-2009, 03:44 PM

This I know about duallies, at least the 92, the rims are hub centric, not lug centric. Meaning the hub keeps the wheel in the right place for rotaion and the lugs apply the going/stopping force. That being said, as long as the hub is the same size you shouldn't have any problems swapping the rims around and drilling larger holes in the 69's to make them fit the 92. The easiest way to tell wether or not the 69's rims are hub centric is to look at the lug nuts. If the side that goes against the wheel is flat, not conicle, then they are definately hub centric. If they are conicle, it may go either way, I dn't know the specifics for that year.

Livrat · 08-22-2009, 03:51 PM

Yes the bolt pattern is the same but 1967-70 used smaller studs than the 92, Yes you could bolt them on using the 69 lug nuts.
BUT.. DO NOT DO IT!
It is a dangerous thing, as the wheels will "rock" back and forth under braking eventually wearing through the studs till they break.. Ask me how I know...
The only way to safely use the 92 wheels is to change all of your studs on your 69 to the same diameter as the 92 wheels.. not a cheap way to go!!

Yes you can drill out the split rims to make them rollers..

I guess I'd have to find drums with larger holes. There's no way larger studs are going thru those smaller holes, right?

sailed2japan · 08-22-2009, 04:41 PM

livrat- good point wish I had thought of that...

You may be able to drill the drums as well. I would think the problem would lye in the knurls of the studs themselves.

I have some dually stuff I'l pm you about.

BCOWANWHEELS · 08-22-2009, 04:55 PM

Why dont you just move the body over to the 92 frame. Then everything under the body will be 1992

**Joesjunk** · 08-22-2009, 05:19 PM

I drilled out the 1/2" lugs on my 68 1 ton and put in the 9/16" ones so I could use the newer wheels. Its not that hard to do, but takes some time

Yea, that's a thought.
I just wonder why they wouldn't work as they are. Think about it, even factory lugs are somewhat smaller than the holes in the wheels. I thought because they are beveled, they get centered as they are tightened. What difference would it make if the hole was a lot bigger than the lug? If the lugs are loose, they're gonna get wobbled out if they're factory or if they're a lot smaller than the hole, either way.

????

63 & 64 Bowties · 08-24-2009, 07:37 AM

any other ideas or comments?
thanks

**special-K** · 08-24-2009, 08:05 AM

The problem is the slop in the wheel hole.If the lugs are torqued down hard enough they could possibly keep the wheel from rocking on the studs.But,maybe not and you`ll be shearing the studs.I`d drill the hubs are press 9/16s studs in.I did it on a`70 to use chrome Budd wheels for `70s disc brake trucks.

63 & 64 Bowties · 11-19-2009, 05:02 PM

Dredging up an old post, but I haven't done anything yet and I have another idea.
What about wheel adapters/spacers? I see ones that are as thin as 1.5" and are 8 on 6.5" to 8 on 6.5" adapters with 9/16 lugs.
I'm just trying to do this the easiest way. It's just a farm truck that has dry rotted tires on split rims and I already have the newer wheels with decent tires.

**slomotion** · 11-19-2009, 05:28 PM

Joe'sjunk is right. Drill the drums to take the 9/16 lug and you won't have any problems, with the exception of having to buy a set of lug nuts too. The old ('69) lugs are a single piece nut that just tightens up against the wheel. The new lug nuts have a captured washer that allows the nut to turn even though the washer is against the wheel. This gives you a truer torque.
Wheel spacers aren't the best idea on this size wheel because as someone above mentioned the wheels are hub centered and the farther away from the hub you get the more room for error.
If you're going to fix this truck up, may as well do it right now, be safe, and on the plus side you've opened up your wheel choices dramatically.
BTW, these are not conical self-centering nuts. They are flat faced relying on the hub for centering.

Not related to your wheel question but the dump bed looks just like the Aristocrat bed I have on my 68 K-30. What type of hoist does your bed have?

Thanks

I would use pre 1970 19.5" one piece dual type wheels.A direct bolt on. It was used from the late 50's to late 60's. Tires are plentiful and they reduce freeway rpm's.They are harder to find than late model wheels, but they are out there.

sea chief · 11-21-2009, 03:56 PM

On my 1970 dumper, I found that I had to use the spit rims on the inside due to the fact that the drum was to big to allow the newer rims to bolt up.

But, I've got FREE wheels and tires already.

The drum was too big where? Can you explain that please?

okay I am a LitTle late for this forum but all of you are drunk oneg nog or some thing!!!If YOU PUT ON 1973 OR NEWER RIMS,YES THE LUGS ARE SMALLER!iF YOU PUT ON THOSE RIMS,GO TO YOUR LOCAL AUTO PARTS OR TRUCK PARTS STORE AND BUY THE CAPTIVE WASHER LUGS(THE SAME ONES ON A NEW CHEVY OR GMC DUALLY) IN 1/2 SIZE,TORQUE THE RIM TO 75-90 FT/LBS AND THE RIM WILL NOT MOVE AT ALL!!!!!!!!!!THE RIMS ON A 1969-79 OR 80 ARE 4.55 OR SO HUB DIAMETER.THE EXACT SAME AS YOUR 1969!!WHEN YOU GO TO THE NEWER RIMS(1995-2009)THEN THE HUB IS 4.79 DIAMETER.ALL TRUCKS HAVE SLOP IN THE BOLT HOLES!IF THEY DID NOT HAVE SLOP THE RIMS WOULD NOT FIT ON THE TRUCK.THEY USUALLY HAVE A 1/8" MORE OR LESS.WE HAVE 2 1970 CHEVYS WITH FACTORY 19.5'S AND ONE 1969 WITH SPLIT RIM 18"S.THE 18 TRUCK HAS A 1/2" LUGS AND THAT TRUCK FROM THE FACTORY HAS A REAL SLOPPY FIT AREOUND THE LUGS.THE 19.5 TRUCKS HAVE 9/16 LUGS AND THOSE RIMS FIT OVER THE LUGS SLOPPY ALSO.AS LONG AS YOU RUN THE FACTORY TORQUE SPECS THEY WILL NOT MOVE.I HAVE A FRIEND WHO TOOK 1999 3500HD (19.5 RIMS) RE DRILLED THE HOLES TO A 8-6.5 PATTERN,USED THE FACTORY LUGS 1/2" AND RACES THIS TRUCK IN FIRE DEPT DRILL TEAMS COMPETTION AND NEVER HAD A PROBLEM.Look up on you tube......fire dept drill team and check out piston knockers or copaigue yellow birds and watch those guys.790horspower trucks and then tell me about the lugs!!

brianthelion02 · 12-28-2009, 12:08 AM

I put spacers with 14 mm lugs on my 69 c-30 so i could ose the late models lug nuts and center caps!! Wen i installed them i used 4 conical lug nuts to center the wheel then replaced them with the late model factory ones! It works great!!

68lwb292 · 12-28-2009, 01:12 AM

They use to make washers that were sightly cone shaped that were made fore this. The tire shop used them on my nissan when I put some after market wheels on it. When you torque the lug nuts the washer centers the hole on the studs and keeps them from slopping back and forth.

63 & 64 Bowties · 10-01-2010, 09:54 AM

Okay, diggin' up an old post here, but I'm just gettin' around to this.

This is the way I was going to go. But one question; I popped a lug stud off the 92 to see how long it was and it's about 2 1/8" long. It looks to me that it's too long to insert it into the front hub. Probably about 1/2" too long. Did you use shorter studs?

Sorry, I have no idea. I don't see any tags anywhere.

Now that sounds like the easy way I was looking for. Happen to have any info on those spacers (supplier, part #?)
