tire howtoo
Did the other side today and photographed the process.
Get the rim/tire off you should see a hub like this.
In the grease there is a cotter pin.
Axle nut was 27mm for me.
hub slips right off. The tapered bearing comes out of the hub too. Be sure to put it somewhere it will not get dirty
Ok, did some math here. Used paint pen to mark the hub so i could scratch a bit off to make my mark for the punch later. Graph paper was all measured out before hand and cut to show where the lugs will go in relation to the original lugs that i used to hold paper on the hub.
All you need to know if you decide to use my bolt pattern is its 2.9mm from the edge of the hole for the axle. Use some graph paper so you can make strait lines and mark out from the edge like this.
punch your marks so the drill bit will center in the hole.
You need to be DANG sure that your hols are right. Used the caliper to make sure both sides were 4.5 inch apart.
This is still not enough. Then make sure all holes are space equal from each other side to side.
One of my holes was a tad in so i moved it out. Tap a few times then check ....check again.
I could not drill at the same time an take photos on the drill press. Don't use the biggest bit first. Be sure to make the hole with a bit about 1/2 the size as the final. Here is what you get.
Grind the back side to get the casting numbers off so the stud will sit flush then using a step drill lightly widen the hole on the side you just ground the casting numbers off of. About 1 to 2 mill deep will do.
Pull the studs through by mounting the hub on your new rim or using a bushing like I did.
Reassemble, make sure when putting the nut back on the axle you load the bearing. Tighten the axle nut on until you cant turn the hub any more then back it off till it spins with no resistance or play in and out. Then put the cotter pin in and you now have your upgrade.
If you have a euro car and don't want to put a converter in you can also upgrade to turn signals and even a reverse light.
And as always i like to have a box on the front.
