Q:bearing spacers on my Rollerblade spark makes removing bearings difficult.?
He changes a lot of wheels when he sets up a booth at events and can pull bearings much faster than explaining how. Use a bearing tool or other object that fits inside the bearing. Just put it in as far as the bearing and lean it to a side to put force on the bearing. Make a rolling motion around a circle with your hand and the bearing will walk out of the wheel. A cruder, brute force, method is to take a screwdriver handle from a 1/4 socket set and put it into the bearing hole (it will just fit). Then twist sideways until the bearing pops out. Most better quality skates have gone to the 8mm axles and the rolling motion is a good method to learn.
Q:ford fusion engine rod bearings?
You rarely replace just the bearings because usually the crank is damaged or worn as well, and the entire crank kit should be installed. You are talking like .0002 clearance there. Well, it's a ford so give or take an inch or so should be like new. Kidding. Almost.
Q:Changed skateboard bearings to bones reds and it made it worse!?
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:Do needle grease injectors properly lubricate ball joints, tie rod ends, bearings?
Ball joints and tie rod ends are like the joint in your hip. The BALL of your hip rotates around in a lubricated depression. Many BALL JoiNTS and TIE ROD ends have lubricant fittings for grease to get pumped into. It prevents damage to the metal ball and cup. OTher cars are totally sealed. Either way is just fine. I prefer sealed opnes on most cars, but only if they have an UNLIMITED warranty. NO MUSS,NO FUSS!
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:A question a bearings?
Van, Something other than an orienteering course has been setup, because orienteering doesn't use bearings. From point A, the competitor might want to follow the trail until it turns Left, and then continue through the forest 10m to B. From B, the edge of the clearing should be good to run along and then the building on the other side will provide a launching point to find C... Consult a geometry student as those angles and distances might be important to them;-) steve
Q:The guy at the auto shop said my wheel bearings have 'play'?
If it really has play, yes, it's serious. A bearing has to be in pretty bad shape to feel enough play If you trust him, then replace them A.S.A.P. If you don't, get a second opinion--soon.
Q:1996 dodge 1500 4wd do they have wheel bearings or just axle bearings?
Sounds like a ball joint.
Q:How often do you clean your skateboard bearings, and with what?
Longboarders need to keep their bearings in EXCELLENT condition, and this is primarily a longboarding sight. Check it out.
Q:help on this math question about bearings?
Sketch the situation and you have a triangle ABC, where A is the starting point, B is the turn after 10km, and C is the ending points. From the bearings, angle A is 75° (90° - 15°), angle B is 100° (85° + 15°), and so C must be 5°. Side c (opposite from C) is 10 km. Solve for side b (opposite from B) using the law of sines: b / (sin B) = c / (sin C) b = c * (sin B)/(sin C) = (10 km) * (sin 100°) / (sin 5°) Now, put your calculator in degree mode and see if the answer is closer to 113 or 114.
