Q:skate board bearings?
8 bearings are in a long board and that means you only need to buy one new set of bearings if your also wondering (8 per pack)
Q:can i use finger acetone to clean my bearings?
?!?!?! NO! Finger acetone cannot be used to clean bearings. You can clean bearings with a few things, I can only remember WD-40 at this point of time. Remember to completely dry the bearings before adding the correct lubricant and re-capping them.
Q:what can i use to clean longboard bearings?
Windex works like magic
Q:How to take bearings off of skateboard wheels?
Take your wheel off and put one bearing onto the truck end pull downwards on the whell and it should pop out. This might take some time but pull swiftly and dont be scared to use some force you will need to.
Q:are Tensor Oust Moc 7 Bearings, Abec 9 Tolerance good skateboarding bearings?
The ABEC scale isn't very accurate for measuring how fast a board can go, hopefully we will one day get a scale that is accurate. You're Bone Swiss bearings probably do go faster, when you're riding your board, challenge him to a race, either you'll win or you got ripped off.
Q:What are some fast skateboard bearings bearings?
If you can spend a lot of money, bones swiss ceramics are the best bearings out there, but run around $120-160. Any bearings that cost around $20 or more are fast, but brand-wise the highest quality are bones. By standards, bones reds are the highest quality for the price. Almost every skater uses bones reds. They cost $20 and are better than flip, panther, and other bearings at the same price. They are quite a lot faster, and a lot more durable as well.
Q:should you replace axle bearings too if your replacing leaking axle seal?
As stated above, check them while replacing the seals. A lot of the times, you can just repack them as long as they're in good condition.
Q:Will my Bones Swiss longboard bearings rust if they get wet?
37 seconds after cleaning and re-lubing. Haven't been broken in yet. Make sure the shields are not dented. they should be flush with the outer race of the bearing. Test: setup Bones Swiss bearings Trucks: Indy Wheels Santa Cruz OG Road riders 75mm 79a I prefer Pig Swiss over Bones, had some that were cleaned and ready for a spare set.
Q:How much would it cost to replace the rod bearings in a 1987 Pontiac Fiero?
Engine would have to come out of the car to replace rod bearings so there would be a fair amount of labor involved in just getting the engine out. Its also unlikely that just the rod bearings are bad, usually if the rod bearings are bad so are the rod journals on the crank and then you have to wonder about the rest of the engine. If you like the car otherwise I would figure on getting a rebuilt engine. Price out a rebuilt engine and then the cost to install it and use that number to decide if you are going to buy the car. If you do get the car take it to a shop and have em pull the motor and have a look at it. If its worth fixing have em fix it if not you are not out anything extra since you would have had to remove the old one to install the rebuilt one anyway.
