- Q: For a skateboard. Which are better?
- Bones Reds try and get ceramic bearings keep maintenance on them every month and don't worry about ABEC ratings cause it counts for nothing and you will have bearings for at least a year or two depending on where and how you skate.
- Q: Ok so my bearing shields recently got bent inwards and i researched it up online and it says that dirt and other stuff can get into the bearings easier and since im sort of a lazy guy i dont want to do the whole cleaning process so can skateshops clean bearings for you like with a dissolvent or something if you paid them a few bucks and also do you think that skateshops can also flatten out your bearing shields as well thanks if you answer
- Yes, they can/ should be able to do that there. Since you said in your other question that you have ceramic bearings, the cost of this cleaning/repair would be alot cheaper than new bearings. I would take it in and see how much they charge, what they suggest, and how confident they are that they can fix it. If they charge alot then just ride them till you notice a decrease in performance. Then take them in and get them cleaned. If they don't charge much and sound like they can easily straighten out the cover, then ya, go for it.
- Q: The serpentine belt in my car came off somehow and I found it in the driveway (this was a few days after it had been replaced) and my dad told me to drive my car to the automotive place without it and if it overheated just to pull over, let it cool, and then keep going. it did overheat and I pulled over, but called AAA and had them tow me, now the guy fixing my car told me my alternator bearings have failed, and that it wasn't like that when he did the belt before. Was this from the drive there? or from something else?
- renewing a belt will often put a strain especially if over tensioned on a bearing set in an alternator. it may well be the initial belt failed due to bearings on way out and having a new belt simply hastened that effect. in either case the alternator is defunct. very unlikely ( impossible maybe) to show the new belt was overtightened. I would just wright it off as bad luck. the overheating will occur if you drive without a belt as most belts also drive the water pump ,hence no cooling.
- Q: I want to take care of my bearings and was wondering what the best lubricant for them was
- ky jelly
- Q: what is the best bearings company for my skateboard?
- bones swiss
- Q: So i have a longboard and the bearing it came with died on me. Changing my bearings for the first time, i had no idea what i was doing until i look to youtube. I did as they said but something fell out. It was my speed ring. So i changed themas i was told and i put the ring back on before the bolt. I dont know what i did but now it spins very fast but slows down IMMENSLY within 10 seconds of a spin test and stops abruptly. What happened? (note: i skated in the rain... Stupid me)
- Well if they are newer bearings you need to break them in what can take awhile depending on how much you skate... it can take a good day to a month or so just break them in and get them going... and from what I read online never use WD40 on them
- Q: i need to change the bearing on my hyundai accent front passinger side, i got it all apart and see i need a press. would it be easier to replace the whole hub i so how do i go about doing it ? any link to diagrame etc.. would be appreciated
- It would be easier to take it to a machine shop and have them press out the old bearing and press in the new or to purchase or rent a hub shark so you can do it yourself (provided you have a compressor and impact).
- Q: Are Rush Bombers good skateboard bearings?
- No the bearings to go with are red swiss bearings. They are sick and last forever.
- Q: So, I guess I need to drop the subframe, crossmember and suspension.I can't get the oil pan out...If you know anything, help!
- Make sure to take the side bolts out of the oil pan. Believe there 12 oil pan bolts 6 side bolts. You can do the rod bearings in the car meaning take the cap off(Do only 1 at a time mark an arrow pointing to the front of the engine if there are no marks on it) But only do one at a time. Rotate the crank so the rod is a straight shot to you, take cap off. Push rod up enough to remove install new bearing. Make sure to put bearings in one way, only fit one way. After installing bearing onto rod, make sure it is flush pull down on the rod itself to seat it in place. Do not use the rod cap the bolts to seat it first. Then once the rod looks like it is in position, then place cap on toque to specs. Then rotate crank if possible to go to next one. Do the next one in line, dont skip around or you may loose track BUT!!!! If you are doing this for the knocking noise at engine start-up, its the piston slap is what is causing that noise it is normal per GM
- Q: how do u clean skateboard bearings?
- you take s socket wrench and loosen the nut and take it off and take off the washer , than the wheel than the other washer . Don't lose ur washers !!! Do this to each wheel . Take about 8 Qtips or more or less depending on how dirty ur bearings are , take the Q tip and rub the dirt off of the bearing . Each side and in the insides .
