Q:Problem With Longboard/Skateboard Bearings?
Don't just let them sit in the solution, you have to shake them around to get the crud out. You can get a Bones Bearing Cleaning Kit, or make your own (Google is your friend here). If I haven't cleaned my bearings in a while, I usually rinse heavily with water to get thick dirt off, then put them in a 90% alcohol solution (50% is a bit low, that's half water) in that Bones cleaning it, shake for ~10 minutes, and then do it again, then wait until they dry (put them on a heat vent or something), then two drops in each bearing and I spin them to make sure they're quiet before re-assembling the shields and whatnot. If they're still noisy, I put another drop of lube in.
Q:Yamaha SR 125 Headstock bearings?
The reason for this is that EVERYBODY replaces old ball and race bearings with tapered bearings, even on my antiques, as they are far superior, last longer, and require little or no maintenance.
Q:Where can I get my PWC trailer's bearings repacked?
your marine service shop should be up to the task of maintaining your marine trailer too. if they arent, you shouldnt be going to that shop to begin with. any normal car mechanic should be able to handle it too. its actually a very easy job, if you dont mind getting grease on your hands. wheel bearings are wheel bearins are wheel bearings..... and there are also places that deal more specifically with trailers. they would be able to handle your marine trailer maintence too. i would suggest you add a set of bearing buddy caps to your shopping list for parts. they have a fitting on them that allows you to pump grease into them without popping them off. and a spring that forces the grease through the bearings and out the wheel seal (if over pumped you will ruin the wheel seal). just pull off a little plastic cap, check that the spring is half compressed and you will have no bearing worries ever again. if the spring is ever getting relaxed, pull out the grease gun and give it a few pumps. bearing buddy caps claim to be a final solution to keeping the bearings full of grease and working properly. IF used properly and kept full, that claim is true.
Q:Front tires making awful noise, told it was the bearings. How do I change the bearings? Dodge pickup 1999 4x4?
First take the wheel off, and see if it is the bearing that's causing the annoying noise. If it is the bearing, proceed with taking off the center hub nut cap. You can pull that off by wedging a flat head screwdriver between the hub and the cap. After that, you will need to pull out the cotter pin that prevents the nut from backing off with a pair of needle nose pliers. Then take off the nut and pull the hub off. Inside the hub is a bearing. Take it out and inspect it. If it's bad replace it. If it's still in good condition, Remove the old grease and re-grease it with wheel grease. Make sure you put tons of grease on it. Put everything back together the same way you took it off, but don't over-tighten the hub nut when you put it back on. If it's too tight you could possibly burn out the bearing. Good luck.
Q:In skateboarding, What does ABEC mean for the bearings?
Pretty much nothing. It is a measure of precision for high speed machinery where vibrating shafts are a problem. Way higher speeds than wheels on skate boards or inline skates. In some cases, higer abec ratings can cause extra drag in the bearings because of the smaller gaps inside the bearing. Some companies (Zero Drag, Bones, Twin Cam) have designed their best bearings to have lower drag by not meeting even the ABEC 1 standard but with the tolerances close in the areas needed to make them run true in your wheels.
Q:Need some help with Bearings in Yr 11 mathematics?
Three figure bearings are really quite straightforward in that it simply means that all bearings are measured clockwise from North. Examples N 35 ° E = 035 ° SW = 225 °
Q:98 Dodge pu - had overhaul , new crank shaft & bearings, still loses oil pressure.?
ok so have you considerd the oil rings being worn? you didnt state if you did top end just crank and bearings so my thoughts are, that your top end is tired, you also didnt mention if it smoked at all, that would be an indication of worn rings. Just because you replaced your oil pump doesnt mean that you didnt get a faulty one, get a compression test done and that will let you know if it is rings.
Q:Cleaning out my skateboard bearings?
first of all NEVER use things like hyd. peroxide or sewing machine lube or WD-40. it clots up, collects more dirt and actually can cause more friction between the ball bearings and the shell. and absoloutly never use water, unless you want rusted shackles. only use actual skateboard lubricants, top kind out there right now is Speadcream by Bones.
Q:Bones Swiss Ceramics vs. Black Panther Ceramics longboard bearings?
I beleive they are the comparable bearing. Bones website calls the comparable bearing Swiss ceramic and Swiss ceramic labyrinth. Si, i could circulate with those that are the low-priced. in spite of the shown fact that, ceramic bearings are actually not cautioned for highway skating. The ceramic balls can not face up to the extreme results of touchdown from super heights. they are basically used for longboards the place speeds can attain in far greater advantageous than 50mph. in case you will concern your bearings to extreme landings, then decide for the labyrinth if used in a dusty or grimy ecosystem, and the standard Swiss if used indoors, or the place there is little dirt.
Q:Can wheel bearings cause humming noises?
If I member correct you have a air cooled v.w. if so it could be the steering damper. super beetles are bad for shakeing. hard to keep wheels balanced.
