Dual set-up for my ‘51 8n

Retpopo · Jan 12, 2021

Just finishing a rebuild. Bought a pair of rear wheel hub
adapters part number NCA 1223 A 1. Wheel studs too short.
Do I replace those with 1/2 longer or buy the FDS 118
extensions?

For a dually setup you need the wheel stud extenders, p/n 8N-1142 and the spacer, p/n 8N-1156. Introduced with the 8N and used for all models thereafter, note the 8-Bolt Hole Pattern so they will not work on a 9N or 2N. The Stud Extenders are also used on the rear wheel Pie Weights. Finding some often requires a search. A guy on the other site used to make them but no longer into tractors and sold all of his stuff.

FORD 8N (& UP) REAR WHEEL SPACERS & STUD EXTENDERS:

Thanks Tim. So what I have is for what exactly?

Dean · Jan 12, 2021

Who knows without a photo.

That said, many folks mistake the wheel spacers introduced in 55 for use with PA rims for dual wheel adapters. Indeed, they are often marketed as such by unknowing or unscrupulous sellers.

Does this look like what you have? This is a Ford wheel spacer for use with the power adjust rims used with the X00 and X01 series Ford tractors.

Retpopo · Jan 12, 2021

Mitchford, Yes that’s what I have. Will have to look at a machinist I guess to have them made up. Btw the rebuild went well. Thanks to all who have helped now and in the past

(quoted from post at 19:53:00 01/12/21) Will have to look at a machinist I guess to have them made up.

Here is a starting point - instant online quote from a reasonably priced company that I have used in the past:

One pair CNC laser cut from 1" plate: $245 per pair plus shipping.
Ten pair CNC laser cut from 1" plate: $129 per pair plus shipping

I have a local shop that would probably beat that 10 pair price by a substantial amount. I doubt they would consider doing one.

I have had simple plaate spacers like those processed by ALRO steel supply. They have in house water jet cutting service.
Might check with your local steel supply house.

Kirk-NJ · Jan 13, 2021

Yea, what you have is extensions for the power adjusted rims. They are not dual wheel adapters. Holes were counter sunk and IMO had just enough treads to hold the lug nut on. Adding a center disc under it and as you found out bolt are too short. I suppose you could replace all the bolts on your hubs with longer bolts. It would have to have same tread so lug nut would fit in counter sunk holes. You could than mount your rims and adjust the rim on the center disc in or out and hopefully they don't hit or are too wide apart that you can pick up rocks between them.

All that money and you still have to buy the adapter lug nuts. Might be cheaper to use aluminum plates in stead of steel.

I think you will find aluminum is more expensive. Lug nuts another $100. Plus a grand for tires, rims, and centers. Big wheelin' is not a low budget sport.

I think the dual wheel spacer ring is at least 1.25" thick. I will have to measure mine.

michford · Jan 13, 2021

Depending on how far away from Michigan you are, I may be interested in the power adjust spacers you have.

Kirk-NJ · Jan 13, 2021

Yep tires, rims, center EZ grand if they're firestones

If you don't mind check the diameter of the holes for the lug adapters while you are at it. I may pursue this idea when I get a chance. I was thinking 8 longer replacement studs might be cheaper than using the M/F adapters.

I'll get full dimensions of the spacer ring tonight. I think there would be a fair amount of disassembly work to be able to press out original rear axle studs and press in longer ones as not sure if longer studs could fit for install without a bit of axle shaft disassembly involving the locking collar. Not cheap, but much easier to stick with special extenders to use with spacer ring.

Kirk-NJ · Jan 13, 2021

Yep plate is 1 1/4" thick or maybe a hair longer

Appreciate the dimensions. I suspect I can get the spacers made at a pretty reasonable cost and a pair will ship anywhere flat rate for $14. Work required to swap studs is part of what I want to investigate. I have to pull the axles on my 8N anyway

Another thought was to use the OEM lugs and nuts to bolt the spacer to the hub and OTS male lug nuts to bolt the outer wheel to the spacer. That would require some machine work that i would like to avoid....

For TOH - Dimensions for 1156 dual wheel spacer:
7.88" O.D. x 1.50" thick
4.12" I.D.
(8) 1.25" holes through on a 6.00" bolt circle
.06 x 45 degree chamfer O.D. & I.D.
Break edges of 1.25" holes

Was thicker than I thought, that will change your estimate.

michford · Jan 13, 2021

Modern view show a smiley face instead of an 8 in parenthesis for the quantity of the 1.25" holes, not helpful.

Thanks!!! Dam close to what i sketched up yesterday. Too thick for laser cutting. Maybe use two .750 spacers per wheel and weld them together. Probably 50% more cut time but material per piece is cheaper so should not be killer expensive. Ill run it through the online system tomorrow to get a ballpark number.

Ferguson used 9/16 bolt sizes

Are you the guy from Traverse City who bought my 8N spacers a few months ago? A guy from Utah, Jim Webb used to make them, may have some more on shelf he'd part with, and Steiners used to make them too and also may still have some NOS to get rid of. Anyone interested should contact them. The original poster asked about the 8N dualies.

michford · Jan 14, 2021

Yes, I bought the dual wheel spacers and extenders from you. I recognized them immediately from the picture you posted and thought gee those look familiar.

steve19438 · Jan 15, 2021

do the stud extenders have a part number anywhere ?

michford · Jan 15, 2021

Diagram from factory parts manual shows 1132, but part number list does not show it. I also did not find anything in master parts catalog that references pie weight parts.
