inlarging a hole

[sawmillman]

I got a hold of some 19.5 rims to put on my dodge dually but the centers are about a 1/16 to small to fit over the dana 80 the holes are about 4 1/2 on the wheels.Does anyone have a idea on how to oversize the center hole other than take them to a machine shop and pay a fortune to get it done?

have them milled out to the proper size, i wouldnt risk trying it by hand

This is not something you want to fool around with. If the wheels don't register on the hub correctly you're looking at a prime condition for broken studs. The cyclical loading will fatigue the studs in short order.

For your own safety get the correct wheels or have them properly modified. You'll also find that for liability reasons, "most" machine shops won't touch anything that has to do with trains, planes or automobiles so get the right wheels.

Are they steel or aluminum wheels?

 

[sawmillman]

Steel wheels. They were made for the gm 14 bolt and just a hair of fitting the dana 80 about a 1/16 or less.I have found wheels that fit for about 3 times what I have invested in these that is why I would rather use what i have.

Not for Wheels. Especially on a Truck bearing heavy loads or carrying people you care about. If the Wheels were Hubcentric it would be a different story. I doubt they are though. If this was on an off road crawler or Buggy I would consider using them. I would suggest getting the correct Wheels though.

If you have a drill press and it will reach, then just get a couple bits and some cutting oil. Give it a try. If we are only talking a very slight difference in stud size / not alignment then why not?

Take about 1/64 off at a time. Good luck.

He's talking about the hub center, not the lug nut hole. Big difference.

you need access to a mill
you will indicate in the wheel and then you can do the overbore with a boring head

another option
if you have access to a lathe and the hubs or axles have the meat to do it you could take it off of them instead

I've seen it done, probably not the safest or smartest way to do it but it did work. The guy made a spacer. Jack the rear of the truck up on jack stands, remove one wheel, bolt on the spacer, bolt the wheel onto that. Have a friend put it in drive to spin the tire and use a die grinder to remove the material. He used nice even pressure until it was large enough to clear the hub.

Keep in mind these were for off road only wheels on a rock crawler. I am not telling you to do this, just relaying what i've seen work.

If you find access to a mill, another way to do them if you don't have a boring head is to use a rotary table. Center everything up then move the table the radius-1/2 end mill diameter and cut while rotating the rotary table. You'll probably have to do the cuts in steps until you get to your desired diameter. I had to do the set of wheels that are on my F350 this way. It works rather well. I had to enlarge them 0.325" in diameter. I of course didn't realize they were to small until after I had the tires on them as they were ford factory wheels and were supposed to fit.
