TUNE UP YOUR WHEELS

CLEAN YOUR SBD WHEELS

  • Clean the outside of the wheel
    • Use 409 or other similar spray cleaner and a scotch bright pad. The red scotch bright pad cleans the best with the least effort, but the others colored pads will work.
  • To clean your wheel bearings you will need some rags, lighter fluid, an air compressor, and a drill.
    • Find a rubber hose to stretch over a bolt and then chuck up the bolt in your drill to spin the bearings.
    • Lay the wheel flat on your lap on some old towels in your lap.
    • The soft rubber hose is placed against the bearing to spin the bearings.
    • Spinning the bearing and flushing it out with lighter fluid will clean the bearings and knock off the loose rust.
    • Squirt lighter fluid in the bearings and blow the bearings out with the air compressor. Continue doing this until the fluid runs clear.

 

 

CHECK YOUR WHEEL SPEED

Check your wheels speed. This does not take into affect the wheel halves being loose, out of round, or out of balance. Obviously if you can see your wheel has one of these defects, you might consider getting another wheel. Do not worry about the wheel being out of balance unless it takes more than a 1/2” washer to balance it. I have found that most out of balance wheels could be balanced with a small thin ¼” washer or smaller. That is not much out of balance and will not affect the performance of the wheel. All wheels are out of balance some.

    • You will need a stopwatch, a one Lb. weight of lead, and the aft axle that is level, tight at the king pin, and the car setting firmly on saw horses or something. Test all wheels on the same axle spindle.
    • Freshly lube wheel with lighter fluid and spin the wheel on the spindle by hand for a few seconds.
    • Stop the wheel and place the one Lb. weight on the top of the wheel.
    • Release the weight on top of the wheel and start the stopwatch. Stop the watch when the wheel comes to a complete stop. Use the same axle spindle and weight to test all of your wheels.
    • A good wheel will roll for 55 seconds to over one minute. I do not like to run wheels that do not test for at least 45 seconds before stopping.
    • Mark the wheels to indicate their speed. Use this information to determine where to place your fastest and slowest wheels.

SBD WHEEL MAINTENANCE

  • Check wheel rubber for ware and looseness, check for cracked plastic around the rubber. If the rubber is bad; I do not think you can get a new one. You may have to replace the wheel. If the plastic is missing, or damaged to where it is not holding the rubber in place, replace the wheel.
  • Check the wheel for out of round. Replace if needed.
  • Check the wheels for loose or missing screws. If the screws cannot be tightened you may want to replace the wheel. To fix a screw that will not tighten, use some epoxy in the screw hole with the screw. Once the epoxy dries, you will not get the wheel apart again. This is a one time fix.
  • If you have a bearing that gets loose, now is the time to fix it
    • Use a punch to remove the bearing as needed
    • Clean the bearing outside and the wheel where the bearing fits.
    • Use sand paper to rough up the bearing outer surface and the bearing hole in the wheel.
    • Use a 5-minute epoxy to secure the bearing in the wheel. Do not get any epoxy in the bearing area.
    • Make sure you push the bearing down flush with the bottom of the hole in the wheel.
