Q:how do you take the bearings out from the wheel?
There are many ways to look at this particular question. To actually get the entire bearing out of the wheel stick a screwdriver into the round hole of the bearing. Then just pop it out. To actually grease the ball bearings within the bearing, you have to pop off the back shield. I only know that you can do this with Bones Reds. They have a special back that sits in the bearing. Pull this off and you'll have access to the balls in the bearing. If you don't have Bones Reds don't try to take the back off, cause it might break the bearing. After pulling off the back, you can put lube in the balls and then spin the bearing in your fingers to spread the lube. To put the back, back on you need to properly separate the bearings. Then place the back on and replace your bearings into the wheel. Before greasing the bearing, wipe off the bearing with a paper towel, clean the bearings as well before greasing by shaking them in nail polish remover .
Q:How do i put bearings in a skateboard if i dont have a tool?
Best way is just push them in with your fingers or place one in the wheel and slide in on the truck and turn it over and do the other side that works good, they pop in place with a little presure from your hand onto the truck. Good luck
Q:Should I mix Different bearings?
Only if you took out slow bearings and replaced them with faster ones. If all your bearings run well, mixing them will do nothing.
Q:Ford F150 Repair Question. Transmission/Bearings?
2000 ford ,, not old enough to have bad bearings INSIDE the transmission yet.normally the Eng goes before those unless your talking about a stick shift and its the throw out Bering on the clutch. those ware out, the more you hold the clutch pedal down the faster the ware , price for a repair over 1000! you can milk it by putting it in neutral at red lights instead of holding the clutch the throw out Bering disengages the clutch allowing the engine to turn and the car to stop, all the force is on the Bering and it only turns when you press the pedal, you will have to remove the transmission completely to replace it
Q:What are good set of wheels, bearings and spacers for outdoor rollerblading?
If they should b able to help you
Q:How do you change rear bearings on a 94 thunderbird?
rear bearings in the engine or the differential. the two are very different but either one would be a project. the engine, you would have to pull the engine out or pull the oil pan off and deal with it that way. pull all of the main bearing caps and replace them. the rear end is a bit more complex as you have to pull the axles out, pull the carrier and start from there.
Q:how are these skateboard bearings?
these are some crappy brand fake bearings. what you need is Lucky Swiss or Bones Swiss those are the best bearings out there look for those on OKorder and see how much better they are
Q:Why are my new black panther ceramic bearings so slow?
I don't know ,but i say just continue to wait for the break in period.. Break 'em in man. make sure the bearings are installed correctly .. Make sure there in all the way in the chamber of each wheel. Don't tighten the bolt on the wheels to much neither.. Another thing that can help is adding some of that special bearing lubricant.. Or you can also apply motor oil. Dip your finger in oil and gently rub it around the side of the bearings.. Not to much just a little .etc.
Q:Help with bearings!!! Pre Calc Trouble?
the trick with bearings is that a bearing angle is different from a mathematical angle. bearing angles are measured from due north and are positive clockwise. [so east is +90 and west is -90] mathematical angles are measured from due east and are positive counter-clockwise. [so east is 0 and north is +90.] so B is almost due east of A, just a little north of it. so A must be almost due west (-90) just a little south of B (-(90+)) draw the picture, use supplementary or opposite angles to find that A is at a bearing -93 deg = 360-93 = 267 deg from B
Q:how long does crankshaft bearings take to replace on snowmobile?
