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:what skateboard bearings are best?
Best Bearings
Q:What kind of bearings in a haro bmx bike?
Walmart motorcycles could be ok, however the climate used are each from time to time of low high quality, and the bike maximum possibly became assembled by employing some1 who had no guidance there4. all of the excellent of success, be it a walmart bike or no! Timothy :o)
Q:should you replace axle bearings too if your replacing leaking axle seal?
not necessary. check them for wear and decide then.
Q:Fork/bearings not fitting into frame?
In the old days they just put grease, and roller bearings until it was full, then reassemble.Depends on the races.
Q:How much hub bearing play should be in my Buick front wheel bearings?
There should be no play in either the bearings or the tie rods. Grab the wheel at 3 and 9 oclock shake side to side, that is usually tie rods, if it's at 12 and 6 then it's the bearings.
Q:Bad CV's or Bad Front Bearings?
CV joints usually make noise only on hard turns under acceleration. It's more of a low knock knock knock noise. Wheel bearings make more of a grinding sound, similar to the noise made by a brake rotor being ground away by the metal part of a brake pad after the pad material is gone. The wheel bearing noise gets louder as you go faster. Clicking noise can be caused by anything stuck in a tire (stone, nail,etc.) and I've seen brakes make a clicking noise when the pads are loose in the caliper mounts. If you jack the car up, you can try shaking the tire in and out holding it on the top and bottom, or from left to right which will tell you if you have worn suspension parts or a bad wheel bearing. Noises are at times hard to pinpoint. Make sure you check your lug nuts, they can loosen up if not torqued properly. Have a mechanic take the vehicle for a ride, test drives are usually free.
Q:how do i check the main bearings? on my chevy?
Nick... it's evident from your previous question about the engine being locked up, that you have no engine building experience and this question confirms it. I assume that you have invested a lot of money in parts and machine work and it would be bad to mess all that up by a shoddy assembly job. I suggest that you find a competent mechanic and let him assemble the engine. BUT to answer your question.....you will need to find out the clearance specs for the main and rod bearings. Then purchase several sticks of the appropriate sized plastigage. Remove all the main bearing caps and clean all the oil or assembly lube off the bearing and crank. If you put any lube on the upper bearing half, then the crank needs to come out and that needs to be cleaned off. With crank in place and dry, lay a 1 strip of plastigage on each crank journal parallel with crankshaft and slightly off center. Install all main bearing caps and torque to spec. DO NOT rotate crankshaft while plastigage is in place. Remove caps and using the paper that the plastigage was in, measure the width of the crushed plastigage strip. If within specs, you're ok....if not...find out why. Do the rod bearings the same way, 2 at a time and dont rotate crank with the plastigage in place
Q:Maths Plse help ~ Bearings, length & triangular running course?
Q:what kind of bearings go in a bmx rear hub?
They are probably 1/4 or 5/32 diameter balls, but the rest of your question leaves me wondering. The hubs that your bike has are quite OK for the grade of bike you have, and just replacing the bearings will have no effect- or if anything a negative effect- on the operation of the hub. Keep in mind that the bearings run on cups pressed into the hub and on cones that are threaded onto the axle, so replacing bearings on a new bike without upgrading these items is useless. By the way, my guess is that the cups and cones can't be upgraded. I suggest that you leave what seems to be a brand new bike alone and stop trying to improve on something that doesn't need it. If you have some problems, see you dealer and explain it to them- chances are any adjustments will be free (or cheap).
