Q:Piston and piston bearings change?
there is more to it than that, first of all if you need pistons and bearings then more likely than not there will be excessive wear on the crankshaft, and also you are going that far, the heads should be rebuilt, because putting a new short block, with old worn out heads, invites more problems. Besides, it would be cheaper for you to buy a long block, and have it installed, than pull the motor and take it apart, add a few parts and put back together an undependable collection of old and new and worn parts. Personally I would put a later model 5.4 chevy small block engine, transmission with the wiring harness and computer. this will make a screaming quick firebird, with about the same fuel mileage.
Q:im replacig main/rod bearings small block chevy...the parts store asked if stadard or oversized?
oversized bearings are used to compensate for crank and block wear, the outside diameter is slightly bigger and the inside diameter is slightly smaller.
Q:Needle roller bearing model NK what does it mean?
Is prefix, needle classification of a, NK is not with inner ring, NKI is with inner ring, different brand name is not the same
Q:Replacing rod bearings 3.3 grand caravan 01?
Yes, although doing it right is tedious. Remove the spark plugs so you can move the pistons by hand. Keep track of which rod and which orientation the caps come from. The new bearings really should be plastigaged (green Plastigage, available cheap at auto parts stores) to verify the clearance. The first source has a good description of how to use it - be sure not to rotate the crank with the Plastigage in place or the piece of Plastigage will be ruined. Remember the bearings will look wrong until they are clamped in place - they will look like they are too large. If the crank journals are shiny you should have no problem; if they have black deposits remove them with 600 grit sandpaper shoeshine rag fashion. Take your time; get it right. Before rotating the crank always make sure the connecting rods are out of the way so they don't get jammed. When in doubt, push them up. !!!Never let any pistons come down so far a ring could pop out of the cylinder bore!!! I don't think it is likely but it would be awful. Get pre-lube and put it on the bearings before final assembly. When it is done, let the engine idle at least 15 minutes before driving, and drive it at modest speeds an hour or so before taking it on the freeway.
Q:Why do some roller bearings have tapered bores on the inner rings?
The tapered ones are made to take a side force. .
Q:Im trying to open up my ABEC skateboard bearings?
I just lubed up my skateboard bearings today. Sometimes you cant remove the shield (the yellow-gold part in the picture). If the shield is removable you can take a razor blade and stick it in the tiny gap between the shield and the bearing wall and lift up the shield to expose the ball bearings. you should do it carefully so you can put the shield back when you're done. If you're doing this to lube up the bearings, drop in a couple drops of lube and pinch the bearing and spin it so the lube coats the inside. then brush the ball bearing with a q-tip to remove excess lube.
Q:Do i have to get a new front hub if the bearings are broken?
It depends on what is actually wrong, and how bad it is. If there is a clicking sound coming from the hub as you spin the wheel, it could be a broken bearing. The clicking is caused by the remaining ball bearings rolling over parts of the broken one. Most cycles have cup and cone wheel bearings, but some later top end ones could have a cartridge bearing. If one or more of the ball bearings has broken, and the wheel hasn't been used much since it broke, then a new set of bearings could be fitted. The hub will need to be stripped, cleaned, checked for wear, and if there is no damage, re - built with the new bearings. If the wheel has been used for some time with a broken bearing, then the bearing surfaces in the hub may damaged, and it will probably be cheaper to replace the wheel, rather than fit a new hub. If in doubt, take the wheel to a reputable cycle store, and ask them to look at it, they should be able to advise you on the best solution.
Q:Do I need bearings with seals or sheilds for my longboard?
Some people mistakenly call shields as seals. No one actually uses seals on skates or boards, they create too much drag. If the drag wasn't there, they would be great since they would actually keep water out. It doesn't matter if you get bearings with metal shields or the neoprene coated ones (more likely to be mistakenly called seals. The neoprene ones are all removable for cleaning and lubricating. Most metal shields are removable but occasionally you find non serviceable bearings that have shields that are permanently staked in place. With some work, you can remove the shields on non serviceable bearings by destroying one of them. You only need one shield that is the side of the bearing you see from the outside.
Q:The difference between NK type and NKI type in needle roller bearings
NK and NKI are light series needle roller bearings. The difference is that one with inner ring and one without inner ring. The following problems are shown. Relevant technical data of the model are compared.

Q:Sdg 107cc front wheel bearings size? any cross reference to which others will fit this hub?
All bearings are made in standard sizes. Take your old bearings to an industrial supply that has bearings and they can be matched with something they have on hand. Typically there are some numbers on the bearing that they use find the replacement bearings.
