what size bit to remove vw bug wheels

Lug Bolts often are incorrectly called "basics". For the 1967 Beetles these bolts are 12mm X i.50 thread with a 9mm head.

Over-tightening the lug bolts non uncommonly results in stripped drum threads. Or, perhaps it is just the years of loosening and retightening the steel bolts that eventually wears the soft cast atomic number 26 threads.

Once the threads in a drum hole have been stripped, the car should non be driven. The lack of one lug commodities can bring nearly failure of the remaining bolts due to the undue stress placed upon them.

An obvious solution is to buy a new drum. But, as with many other Volkswagen Beetle situations, there is a good solution which will salve that drum!

But, first, allow's talk almost some tools which volition make this job possible. If you don't own the tools which we volition discuss, or don't want to own them, you may be able to find a shop or VW friend to exercise this repair for y'all. My VW friends and I accept found it difficult to locate a shop with the proper tools to do this chore.

An alternate idea would exist to purchase the tools, and then to take the drum and the tools to a qualified machinist to have the work done.

You will need the following:

• 1. Drill Bit—31/64th inch
• 2. Tap—14mm X 1.50 Thread. Use the taper or plug (or "spiral") tap
• 3. Die—14mm X i.fifty Thread
• 4. Lug Commodities from a 1968 and afterwards Beetle, Type three or Karmann Ghia (United states specs)
• 5. Tap and Die Kit with the proper tools for using the Tap and the Die
• 6. Heavy duty bombardment-powered or electric 3/8ths inch Drill Motor or a Drill Press
• seven. Light oil or some other drilling-aid fluid—even WD-forty
• 8. Torque Wrench

Compare the 12mm lug commodities and the 14mm lug commodities—both in bore and in length.

Remove the offending brake drum. Time to practice a little cleaning of information technology, anyway. Maybe even to paint the outside so that it will resist rust better. The bandage iron holds pigment well. If you were in a bustle, you COULD do this job leaving the drum on the axle. This is not advisable since it leaves metal shavings in there with the brake shoes.

Showtime y'all volition need to drill the stripped hole to the next size. Wanting to leave every bit much "meat" as possible for the new threads, we are going to utilize a 31/64th bit. A ½ inch fleck will work but will remove likewise much metal and can result in weak threads when the hole is tapped.

Drill the hole cleanly. Usually it is piece of cake to hold the drill motor directly while drilling, but be every bit careful as possible to get a good, directly pigsty. If you have a drill press, this process will exist easier.

Now, for the 14mm X 1.50 tap. Install the tap into the proper handle from your tap and die kit. Once again, taking care to hold the tap straight, tap the new threads into the hole. You can utilize a light oil, or even WD-40, to help the process.

Clean the new threads well using compressed air, if yous have information technology. If not, a small toothbrush or other device will piece of work. Computer-cleaner canned air will work.

Apply a wire wheel or another cleaning device to thoroughly clean the threads of the 14mm lug bolt which y'all take selected every bit the replacement bolt. Rusted bolts will not torque smoothly.

Lay the wheel over the drum and install the 14mm bolt into the newly threaded hole. The bolt may beetle through the pulsate a bit. If so, this protrusion should be removed so that it will non bear upon whatsoever of the braking machinery as the drum turns.

A bench grinder works well to shorten the bolt, simply a hacksaw besides volition piece of work. Secure the bolt head in a vise and cut to remove the tip of the bolt.

In one case the excess has been removed, I like to run a die over the threads and so that they will be straight. If no die is handy, use a modest file to straighten the threads at the tip and then that the bolt will turn into the pigsty smoothly.

One time you are satisfied with the commodities length, reinstall the drum onto the axle.

In the The states, the 1968 and onward, Beetles, Karmann Ghias and Type 3s have the 9mm head just equally exercise those of the 12mm bolts for the "wide-five" drums. Every bit a quick fashion to recognize the larger bore bolt and hole, use a spot of paint or fingernail polish to mark the bolt and the hole.

With the automobile still on a jack stand up, position the bike and screw all 5 bolts in past hand until the beveled shoulders have seated. I use a socket at that point to tighten all of the bolts, going diagonally from bolt to bolt. Tighten until all are well secured but not all the same torqued, due to being off the footing.

Now, we come to avoidance. Torque the 12mm lug bolts properly. Don't use a big wrench or socket bar and stand up on it! Use care and likely yous won't have a repeat performance. Lug bolts for the "wide-fives" (5-lug) '67 rims should be mitt-torqued to 72 ft/lbs. (14mm X i.50 bolts should be torqued to 87-94 ft/lbs). The paint-dot will help you to remember which is the 14mm bolt.

Lower the bicycle onto the ground and torque the bolts, going diagonally from one bolt to the other until all are properly torqued. Maybe you lot have a more than modern torque wrench than mine!

And, there you have it—one salvaged v-lug drum. Plus, you take a kit for the next stripped thread situation. If you have a close-knit VW club or group, mayhap y'all have communal tools. In my case, I lend this tool kit to my VW friends so that they won't have to purchase the set themselves.

I purchase used lug bolts at swap meets someday I see them. I find them to be handy for situations where I am working with a auto that is missing one or more. Deport a couple of each size with you in the corner of your road tool kit and you'll be thanking yourself when you're down the road. Your VW friends will be thanking you too…when they become stranded and find that yous take just what they need to get going over again.

Special Mention: I desire to give thanks fellow-Texan James Anderson for starting me on this journey. Soon, James is working to complete the restoration of a blackness 1967 Protrude.

My wife, Neva, and I accept been driving and working on VWs since 1976. In fact, we raised our family unit in these cars. Now, we are retired and enjoy VWs equally a hobby. The '67 Beetle always has been our favorite year. We own a '67 Beetle and a '68 Karmann Ghia.
