If it's non catalyst then it's over 8500 gvw and takes the 3" brake shoes.

 

Non catalyst?

 

If there isn't a catalytic converter I think is what he means.

 

oh. No cat, but cant guarantee it left the factory like that. That is one of the first thing removed from most farm trucks (as this was) because it is a fire hazzard when parking or driving in dry fields.




anyway. they have both sizes in stock, just have to order the cables. Will deal with the shoes when I get them apart this weekend.

 

I would bet on 2 1/2" that's what the '90 parts truck (Big Ugly) had also my '86 dually had 2 1/2", the rear in it now has 3".

 

The emissions compliance sticker under the hood would tell you if it was NON-CATALYST.

I knew I had seen that terminology somewhere...






I guess its the 3" shoes for me. Will let you know if I find differently.

 

I'm assuming you have a 10.25" rear and 16" eight lug wheels if it is a "heavy duty" engine compliance sticker.

I know I have the 3" shoes.
Though that may be part of my 'towing package'...

 

Correct. So does this tell me it's a F-250 HD?

 

Don't bet on that Jim, mine is crew cab dually with 460 and C6. It came with 2 1/2" shoes and is the 7400 lb RGAW rating. I now have 3" shoes on the rear as that's what the 93? rear came with. BTW, mine is 10,000 GVW.

 

"Heavy Duty" is over 8500# GVW Bill.
This is what his compliance sticker indicates.

If I had to guess, I would say he has the 3" wide shoes.
But I have been wrong before...

 

Mine states "This engine conforms to U.S. EPA regulations applicable to 1986 model year heavy-duty engines" It also says in big letters NON-CATALYST

 

ic you cant wait, but here is a good place to order brakes and stuff : wundercarparts.com

My last order was Raybestos dually drum's and shoe's delivered for 150$. It would have been 300$+ locally, and not Raybestos.

 

Bill,
This is the 7400# truck? Or the 10k one?
One thing I notice is that my '87 sticker has all that non-conformance penalty legalese, that your '86 doesn't

 

The rear gross axle weight on the door sticker is 7400#, the gross vehicle weight rating is 10K. I suspect the legalese is due to being a 1987 model. Ford may not have had the EFI system for the 460 debugged completely in time for 1987 introduction, same for the 351 HO that year. Both applications seemed like overlaps. On the brakes, Ford may have just increased the shoe width for 87, although the 90 parts truck was an F250 with trailer tow and had 2 1/2" shoes. Maybe it's like Chrysler products, you need the old ones with you to match up?
