Crankshaft flywheel flange runout.
The crankshaft flywheel flange must be perpendicular to the axis of rotation of the crank with no permissible runout. Place a dial gauge on the bell housing and position the tip against the flywheel flange, parallel to the crank axis. (Perpendicular to the flange surface). Zero the gauge. Rotate the crank slowly by hand and watch for any movement. Any runout must be eliminated (because it will be compounded by the radius of the flywheel.)
Flywheel friction face and rim face runout.
With the flywheel now mounted to the crank, Place a dial gauge (magnetic clamp or mechanical clamp) to the bell housing and point the dial gauge perpendicular to the clutch friction face on the flywheel. Slowly rotate the crank and check for variation (runout). Maximum permissible runout is 0.01mm per 10mm of flywheel radius. Thus for a typical 300mm dia flywheel, max runout is 0.15mm (0.006"). (Runout here could cause rapid wear of the clutch splines or the driven plate breaking away from the splined hub due to continual flexing.)
Reposition the dial gauge to point at a smooth piece of the flywheel near the starter gear teeth (rim), once again parallel to the direction of the crank. Slowly rotate the crank and note any runout or warp in the flywheel. The same maximum permissible runout applies here.
Bellhousing (gearbox) runout
Repeat the exercise with the dial gauge clamped to the flywheel/clutch assembly pointing out (radially) to the bell housing locating the dial gauge point on the machined face of the bell housing that locates the gearbox. (At right angles to crank direction). Check for radial run out. Maximum permissible runout is 0.20mm or 0.008".

How can you measure electric motor RPM without a strobe?
Two methods, one uses a dial that is held in the center of the revolving shaft and is directly read off of the dial face. The second method uses a strobe light. The light is focused on the shaft and the dial on the strobe is turned until it looks like the shaft has come to a stand still. The RPM is read off of the meter face of the strobe light.
What has dial-up go to do with ICT?
dial-up is when you have no brordband and you have to dial-up to get on to the internet.
What is the function of the adjusting screw in the Bourdon gauge?
Bourdon gauge is a type of aneroid pressure gauge consisting of a flattened curved tube attached to a pointer that moves around a dial. As the pressure in the tube increases, the tube tends to straighten and the pointer indicates the applied pressure.
What would you use to align something in a four jaw chuck on a lathe?
It depends on the surface finish of the workpiece. For machined surface a magnetic base dial indicator is used. For rough or un-machined surfaces a surface gauge is used.
You are using a dial gauge for alignment. dial gauge is fixed on motor shaft. during checking after every rotation reading changes by 0.02 to 0.08mm. it the problem of dial gauge or motor?
almost the problem in the dial gage
What is dial gauge?
A round gauge with a needle to point at the measure.
How do you check hose excentric by dial gauge?
To check hose eccentricity using a dial gauge, first secure the hose in a stable position and ensure it is free from any bends or kinks. Place the dial gauge on a fixed point adjacent to the hose and slowly rotate the hose while observing the gauge's reading. The gauge will indicate variations in diameter, with deviations from a consistent reading signaling eccentricity. Record the maximum and minimum readings to assess the extent of the eccentricity.
How you calculate deflection of a dial gauge of least count 01mm?
To calculate the deflection of a dial gauge with a least count of 0.01mm, you read the measurement indicated by the needle on the dial gauge after it has been set to the initial position. The deflection is the difference between the initial reading and the final reading on the dial gauge. Deflection = Final reading - Initial reading.
How can you measure by a dial gauge?
first fix the dial gauge at a zero settling level than place the object to be measured below it then move it to touch the thing when it touches mark the reading whether its +vwe or -ve then length equal to =original length+dial gauge reading *least count
How do you measure the dial face of a pressure gauge?
by measuring its diameter
What is the best way to measure the spices in a cookie?
Dial gauge.
How do you line up pump shaft?
To line up a pump shaft, start by ensuring that both the pump and motor are securely mounted on a stable base. Use a dial indicator or laser alignment tool to measure the alignment between the pump shaft and the motor shaft at both the vertical and horizontal planes. Adjust the position of the motor by shimming or moving it until the shafts are properly aligned within the manufacturer's specified tolerances. Finally, recheck the alignment after securing all bolts to ensure that no movement has occurred during the tightening process.
What are the sources of errors while measuring Vernier height gauge?
today i observed errors between puppy dial reading & height gauge dial reading. this was 10μ to 20μ when we go to .1 mm
What does bourdon gauge measure?
A bourdon gauge measures fluid pressure in a system by using a curved tube that straightens in response to increased pressure. This straightening movement is typically converted into a mechanical reading on a dial, indicating the pressure level in the system.
How do manual weight scales work?
They have a spring attached to a dial or needle pointing at the weight on a gauge. Both spring and gauge are highly calibrated.
How do you check impeller back clearance?
By the use of feeler gauge and with dial indicator as possible.
