Hey I am looking at getting this truck to use to haul with, I don't know much more about it than that it an 80-94 F800 with a diesel motor. The owner would be letting it go cheap which is why I'm looking at it. Are the motors in these trucks any good? I was reading that it could be either a 6.6, 7.8, or a 7.0. If the truck is going to be a big hassle I'd rather know now before I get it. Also when I go look at the truck is there anything that I should make sure to look for? Any common problems with these trucks?

 

1981 thru today: The 8th digit of the 17 digit VIN is the engine code.

 

Cool looking truck. Post the VIN and we can decode it for you. Post the whole door tag and we can tell you a whole lot more about the transmission, axle, paint and body.

The year matters in terms of which version of which motor, that can make a pretty big difference in getting parts and working on them.

The full air brakes are far more reliable and cheaper to fix than the hydraulic I'm told.

 

Could have a Detroit Diesel 8.2L, Caterpillar 3208, Ford/New Holland 6.6L, or a Cummins B5.9.

 

Yeah I will try to get the vin off of it this weekend, it's near my hunting property, so can get the info before then. I really hope it doesn't have air brakes cause then it would require a CDL to operate

 

My guess is closer to a '95, 7.0l turbodiesel, spendy juice brakes.

 

CDL depends on GVWR. 26001 and up = CDL for most uses. (RV and agriculture are two exemptions)

Air brakes might require a test and endorsement on you license. See your state DMV /driver licensing web site for the correct answer.

Having said that, I would expect an F800 to have a GVWR greater than 26000.

 

Yeah I would be putting ag plates on the truck, but a give of 26001 requires an F endorsement and a class c cdl, but it looks to me to be a hundred series which usually have gvws of 26000 and under, the thousand series usually had the higher gvws

 

If it's under 26,000 pounds with air brakes it still doesn't need a CDL.

Looking at it, I suspect they are hydraulic brakes.

 

I am betting on 8.2 Detroit. Has 30,000 gvw at the least. Looks like still riding on 10.00-20s which are hard to come by. Cant tell if single speed or 2 speed R/A. Proably why cheap is engine is no good and you really don't want fix that 8.2. Parts are hard to get. I know I am running one in a 83 800 with hyd brakes. Chasing engine oil leak now.

 

Not to worried about the tires, I can get them by the pallet, just cost about 300 per tire, my other trucks still run 8.25-20 and 9-20. I've heard that the 8.2's are a pain. Also I kinda want to pick it up for the cab. Crew cabs are getting hard to find and that one would be a good one to swap onto a pickup truck.

 

600 up cabs mount different than 350 down cabs do. In my part of the USA you go asking about 8.25 / 900 / 10.00 ya just laughed at. Say mite maybe find caps but that's it.

 

You'll have better luck with metric tires. A 255 tire is roughly a 10" tire.

 

I'd just as well stick with the 10-20's and in Michigan around the farms there are still so many of these trucks that honestly should not be on the road and still are that it's not to difficult to find shops that do split rims and can get the 10-20's, plus you don't have to deal with getting different rims that are 22.5
