The Stovebolt Site Forums The Parking Lot Big Bolts 46 2 ton dual rear wheel spacer

Can anyone tell me how the rear dual wheels should be installed, including the spacers and the nuts?

Hub or stud centric? Particular vehicle?

1946 Chevy 2 ton. Seems to be hub centric. There is a spacer, I am guessing for between the duals. The spacer is flared on one side. Two of my wheels the spacer flared end fits into. The other 4 wheels the flared end does not fit inside the wheels.

Dayton wheels will use a large steel spacer between the inner and outer rims. I think you may be describing a plate with lug holes? that would go on last on the outside dual with the flare cones pointing out. Pictures would really help here so we can give accurate info.

The GM Heritage site shows only disc style wheels for the '46 2 ton trucks. If you have matching wheels for all 6 locations, the rear set-up should be, #1-inside dual directly against the hub, #2- outside dual directly against the inside wheel, #3-torque plate/reinforcement plate with raised cones facing out, #4-lug nuts.

Torque plate goes outside of last wheel, front in this case, nuts register in it. Modern torque plates have 10 bolt holes in them, even though only 5 used in front. Older ones came in 5 and 10.

This is helpful and thank you to all of you.

I have never heard of the term #4 lugnut, so I will have to look into that--I don't have enough lugnuts, so will have to find some replacements.

Also, I find it interesting that the "Torque Plate" fits inside two of my wheels hub opening, but not the other 4 wheels. It makes me wonder if the "bigger" diameter wheels should go on last and the Torque plate flare point inward, inside the wheel hub opening, to make it fit tight?

I have the 5 hole cover for the front, and two 10 hole flared "covers"/"torque plates" for the rear.

I will take some pics.

I was referring to the order of assembly, #1, #2, #3, #4. Pictures would probably be a great help, we may be barking up the wrong tree with the responses up to this point.

Well, I am trying to attach pics. Here goes nothing...

1st pic is the torque plate for the back the cover for the front and two types of lug nuts that came on the truck. The big ones were on the rear the smaller ones were on the front with a lock washer.

2nd pic is the torque plate partially on the rear hub with the flare pointed outwards.

3rd pic is the torque plate inside one of two of my wheels that the flare fits inside. The inside diameter of the hub hole in these two wheels is roughly 4-7/8"

4th pick is the torque plate against one of my 4 other wheels. The flare won't fit inside, but the wheel will fit over the hub. The inside diameter of these 4 wheels is roughly 5-3/8"

Had I known that I had wheels of different hub opening sizes, I would have paid attention when I took them off years ago.

I guess my question is, anyone know why I have 2 of 6 wheels with a larger hub opening than the other 4. Are people sure I should not put them as outside duals and put the flare plate with flare side inward to space these two wheels with larger hub openings?

Now I will hit post and hope the pictures get sent with this note.

It looks like you have a mish-mash of wheels, torque plate and lug nuts. Who knows what has transpired over the years.

But you say that in the 4th picture, where the torque plate won't fit into the wheel hub opening that the opening is 5-3/8" diameter while the other one where the torque plate fits with the flange inside the wheel has an inside diameter of 4-7/8". Did you mean the wheel in Pic #4 is 4-3/8" inside diameter?

Also, the picture of the torque plate and lug nuts shows that the nuts have been tightened down on the flange side of the torque plate, from the scarring. The torque plate has no chamfer for taper seat lug nuts, so those would be the wrong ones to use. It looks like the torque plate should be installed with the wheels that have the larger hub opening to help center them.

It looks like the torque plate with the extended housing is designed to mount modern(‘57 and later) tubeless wheels on earlier smaller diameter hubs, although I am not sure from the pictures if it is extended enough to pick up two wheels, front wheel OK! Saves making a hub spacer, though.

Looks like the spacer could go inside or outside the wheel, increasing the tread slightly.

If I'm reading all this right, you have four wheels with the smaller ID, two wheels with the larger ID, and two torque plate/spacer shims? If yes, then four of the wheels would go to the rear, the ones with smaller hub holes. The two with the larger holes would go to the front, I would guess spacers to the inside which would center the wheels on the smaller hub diameter.

In 1954 GM switched to a 5.25" pilot diameter on the hubs and 5.25" bore in the wheels, from 4.75" in earlier years. (see tech. tips) The hole pattern is the same. Those are the two wheels you have with the larger bore. I have two wheels like that and made two rings to sleeve them so to pilot the wheel on the hub correctly. The plates only go on the outside of the wheels with the radius turned out just under the lug nuts. 5/8 fine nuts from your local truck spring shop work great for lug nuts, because there is no need for piloting. Because the hub and center hole in the wheel pilots them. Hope this helps.

Thanks, everyone.
