86 F250 wheels won't fit new rotors (Fixed!)

I'm working on a 1986 (11/85 production date),F250/6.9 supercab 2wd 8800 gvw 3765 ft 5915 rear .Installed new rotors (part # is correct from a number of sources) and the hub is about .125 larger than the wheel,s center hole,the studs line up perfectly.
The original rotors were stud piloted with no hub guide at all. The truck is owned by the original purchaser with only 85,000 kms with all original ford parts and has never been messed with.The wheel code is 16x16k and are 8 stud,not sure where to turn , any help would be greatly appreciated.

Also on the rear,the new adjuster cable guides sit too high on the new, as well as the old,brake shoe shortening the cable resulting in the lock riding high on the adjuster wheel.Again the part# check,s out correct.
Thanks in advance

Are the part numbers Ford, or from the aftermarket sector?

D6TZ-2A176-B Right & D6TZ-2A177-B Left .. Self Adjuster Kits, include lever, cable and etc: 1980/97 F250 w/12" x 3" brakes.

12" x 2 1/2" brakes use different kits.

Rotors listed under front driving axle parts lists, need ID tag number to confirm. There are dozens of different parts lists!

sounds like there is something with the part number.

I get E7TZ 1102-C for the correct ford part number. That is for a 1986

Do you have a dual or single piston caliper? Seems that's one of the changes that occured between 85 to 86.

Old rotors will not have Ford part numbers marked on them. No Ford part numbers marked on parts after 1956, just ID engineering or casting numbers (when applicable).

Where did you get this Ford part number from? I just looked thru dozens of section 30 front driving axle parts lists, couldn't find it.

Then I looked in section 11.1 = front brake application charts:

E7TZ-1102-C (Ford Dealer parts locator system sez: replaced by YC3Z-1V102-CA) = 1984/98 F250 H/D & F350 2WD with dual piston calipers.

Thanks, Bill; Kevin is something of a newbie at this. He was even gonna come visit me a month or so ago but his trip to Denver was canceled.

No offense, Kevin (I'm sure you understand).

If you come and visit me, leave your bra at home. We've got more than enough nuts living here in LA LA Land as it is.

My guess is, Kevin googled it, cuz who else has a 1980/89 Ford light truck parts catalog besides you, Gary, me and the fence post?

I can think of another, but we know he prolly hasn't looked in it, just bought it for ***** and giggles.

I got the parts catalog Bill. Section 11.1 is also where I pulled the same part number you got.

Nowhere near as proficient with it as you all...but learning

Kevin's been answering LOTS of parts catalog questions in the last few months. He's better and faster at it than I am, but that's not saying much - huh?

Not nit-picking or pointing fingers, but the OP did state 2wd, so 2wd part numbers are relevent.

However, having worked in the service dept of a Ford dealer during 83-86, I remember that somewhere along that timeframe, Ford went from using lug-centered wheels with tapered lugnuts, to hub-centered wheels with a conical washer type lugnut. The latter style also had a larger center, so the older wheels couldn't be used.
I believe what has happened here, is that OP was given hub-centered rotors, instead of the lug-centered type the truck had previously.
The fact that the OP says it's never been modified doesn't really mean much, as it could have been done by a 3rd party, before the truck ever made it to the dealer as a "new" vehicle. This would render the parts catalog less than accurate.......
Not all dual rear wheel trucks sold by dealers, left Ford Motor Company plants with dual rear wheel axles.

67 year old eyes missed that.

If truck modified by FoMoCo (as original purchaser requested something that was not an RPO) between the time it left the assembly line and arrived at dealership, it would be a Domestic Special Order and have a 6 digit DSO code.

Domestic Special Order parts are not (usually) listed in parts catalogs, dealer contacts Ford, passes along the DSO. Ford looks up the order number (last 4 digits of DSO), then tells the dealer where the special parts could be obtained.

6 digit DSO also applies to special paint, there would be no color code(s) on the Warranty Plate/Certification Label. Same scenario applies, dealer needs paint formula(s), contacts FoMoCo w/6 digit DSO.

Some 1983/89 F250's came with 8.8" rear axles. Ford never called 'em light duties, but that's exactly what they were. Sterling 10.25 rear axle intro'd 1985.
