A little movement is normal but more than that may indicate broken motor mounts.
Generates Power by burning fuel. This Power is then utilised to move Car at different speeds by Mechanical Gears.
Well yes and no. It should more around in a circle when the engine is started. The rotor should not move except a hair with the engine off.
A Reverse Shaft is the shaft which rotates in the opposite direction of the engine driver shaft with the help of meshing of gears mounted on it to the gears mounted on engine driver shaft when reverse gear is applied. The reverse shaft allows the vehicle to move in reverse direction. Sanjay Singh Rathore (ME 3rd year) M.I.T.Mandsaur
Could be as simple as the release button is broken, it is the button you push when changing gears, if it is broken you will not be able to move the shifter.
ALWAYS CHECK THE MOST OBLIVIOUS FIRST, THE AUTOMATIC TRANS FLUID, THE LINKAGE AND DOES IT GO INTO OTHER GEARS?
If you are referring to an internal combustion engine yes they should be tight and not move.
The coolant should circulate through the entire water system.
if you mean it wont move, perhaps you have drained the transmission oil and not the engine oil. this would cause it not to move.
Gears move about an axis, which means they can only move clockwise and counterclockwise, not left or right. That said, if you have two gears, made to rotate by a motor in opposite directions, and interconnected by a chain of an odd number of gears, then the two motors would work against each other. Depending on the strength of the motors, gears, and axles, the mechanism will either break, not move, or move in the direction forced by the dominant motor.
The first skill to being a mechanic is to know cars. basic skills are changing a tire, changing the oil, then you can move on to tune ups, reading check engine codes.
loose bolt on distributer will allow distributer to move worn or stretched timing belt or chain can slip or jump out of timing broken tooth on timing gears If it's an older engine, with points, they just wear out.
