The bearings
If you are referring to an internal combustion engine they are also called the 'big ends'. These are the bearings on the crankshaft and connecting rods, the bearings on the other end of the connecting rods are the 'small ends'.
Wheel bearings are small metal rods or balls that are placed between the inside of a wheel and it's axle, in order to reduce friction.
No. Crank and main bearings can be get at by dropping the oil pan, but to get to the small end rod bearings you've got to get the pistons out.
engine bearings failed . do not run engine until bearings have been replaced. (note) count the bearings that came out in the oil and compare that number to the number on your new bearings. any bearings left in the engine can become failed with other parts and harm the engine. Some times, magnets will placed into oil filters.
There is no such thing as outer main bearings. The main bearings go inside of the main caps that hold the crankshaft in the bottom of the engine. To get to the mains you will have to remove the oil pan.
Bearings? They are small round metal things that have little ball bearings inside (hence the name"Bearings"). They sit inside the middle of the wheel. When you are riding, bearings keep the wheel spinning when you aren't pushing the board so that you keep moving and don't stop abruptly.
Ball bearings
On the east coast of England we called them nanniecotes (not sure of the spelling as it is a local word) This was the word used for any lobster that was under the legal size!
Small Town England was created in 1997.
Small layers of the clutches, seals, and bearings wear off with time.
