Remove Rotor from Hub [help]

[waywardson]

Hi i recently bought some new rotors for my 1975 manta. well when i took the old ones off i ran into a problem separating the rotor from the hub. seems the 4 screws holding the hub to the rotor are stripped and i have no way of getting them off.

i was wondering if i should buy the entire hubs brand new and if so where would i find them? and if im able to remove the screws somehow would anyone be able to sell me some replacement screws or know were to get them?
thanks in advance

You could get someone to weld bolts onto the striped bolts and remove the rotors that way . HTH

Since they are torx screws they have a round head and welding a large nut to them would be quite easy. Try quenching them with wax or penetrating oil after they are welded, they are almost sure to come out.

I have roughly over 50 of them in stock however are you sure you are using the right tool to remove these bolts? They look kind of stripped to the naked eye however they are substantially strong and decivefull.

These are not torx, you will need an 8mm serrated tool bit, which you can get at NAPA for $7.00. Use the tool bit with a hand impact wrench and they should come right off.

Juan nailed it dead on!
Why not buy the whole kit which I think was around 20 bucks. If you own an Opel you'll need the other bits sooner or later.
Clean out the bottom of the bolt as good as you can and it's not a bad idea to seat the tool with a hammer before any twisting motion is applied.

You could use a drill bit just large enough to fill the space inside the head. When you have drilled enough the head of the bolt will fall off leaving just the stud. Seperate the hub from the rotor and use a stud remover from there.

This was my first thought also. A couple of extra tips to go with Juan's guess. If you don't have a hand impact and don't have a vise large enough to hold the hub you can drop the hub inside of your wheel/tire combo. Between the friction on the floor from the tire and the extra leverage the larger diameter tire will give you, you can easily hold the hub for removal with a rachet. At least that's how I usually do it.
Second tip: Compare the diameter of the replacement rotors to your old ones. I've seen suppliers substitute the earlier smaller rotors for the larger '75model rotors before. They will still bolt on and work but you loose some of the advantage of the larger pads on the '75 calipers

I have used a Vise Grip chain wrench to hold the rotor while torquing the (4) bolts to the hub. It is a handy tool for holding diameters, changing shocks, or stuck oil filters.

I'm with Harold...I turn a tire/ rim over and set the hubs lug bolts down thru the rim and have never had any problem seperating the hub and rotor.

he, he, i can say i cheat. my dad was an Opel mechanic back in the day so i have an impact socket that zips them suckers off quick as anything
