Q:how to replace front wheel bearings on AWD vehicles?
Remove the knuckle and axle. press the axle flange off then bearing with a bench press.
Q:bearings & grease question?
Bearing manufacturer's recommend 25%-33% fill for the voids in radial ball bearings. They cite shear, and churning as sources of volitalization of the grease which leads to loss of the lightest fractions; and reduction of lubricity. See the source below:
Q:Main and rod bearings?
Proper way is to mic the journals for size. But in many cases you can still read print on back of old bearings. Originally there would have been (std) printed on back of bearings if they are standard or original size. If crank was turned say ten thousands, bearing would have (.010) printed on back for undersize crank and so on for different sizes.
Q:Why do so many large railroads (ie,class I) refuse to let rolling stock that has friction bearings............
Friction = heat Heat = fire possibility Fire possibility - liability of railroad Another item to consider -- roller bearings have been used for so long, I don't think there's anyone left of any railroad that knows how to repair friction bearings.
Q:f-250 changing front wheel bearings?
Well, what's the problem? Do you need to know how to do it? How much it cost? What are wheel bearings? You have tapered bearings. When they go bad you change the inner and outer bearing plus wheel grease seals then get them repacked. Sometimes you can just have them tightened and that fixes it
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).
Q:Condenser fan motor bearings are bad on my home ac unit how can I tell?
best way to check bearing is to take the condenser fan motor (with power off and double checked with a meeter) have the moror sitting with shaft up. hold the shaft and move it side to side. it wont be visible usually but if you feel any give in the shaft then the bearings are bad. However many use the word bearing loosely as many condenser fans use sleeves instead of bearings (cost of manufacturing). The smallest ever so slightly feel of play can show warn or bad bearings or sleeves. I have seen condenser fan motor with bad bearings that passed this test and ran normally until they got hot just as I would about give up on it and when they got hot they your start to slow down or sequel. With most of the motors now days it better to replace the whole motor than just the bearings. If you do not trust your tech then call somebody else. I recommend having a N.A.T.E certified technician as they have higher certifications. also when you call the company ask if their techs are paid hourly, commission or piece rate. many HVAC company's now days are paying their employees on piece rate which means the more parts they change the more they get paid.
Q:what are the best bearings to buy for my longboard?
I okorder.com/
Q:On a big truck that holds a 3 pc. drive line and has 2 carrier bearings, is it best 2 keep the bearings level?
yes you should keep them level,because if you dont,it will wear the bearings.
Q:Does WD-40 still not good for Skateboard bearings?
WD-40 will atract any sort of dirt dust and will slow down your bearings. You should take each bearing apart and place it in something like nail paint remover, then buy some lube from your skate shop! works everytime
