What is flywheel runout?

What is flywheel runout?

Flywheel Lateral Runout Flywheels provide a clamping surface for the clutch disc, absorb heat, and dampen engine pulses and vibrations before they pass to the transmission. Inspected the flywheel’s surface for scoring, wear, and lateral runout whenever replacing the vehicle’s clutch disc.

What should flywheel runout be?

The difference between the lower measurements and the higher measurements that are performed at all four points must not be more than 0.15 mm (0.006 inch), which is the maximum permissible face runout (axial eccentricity) of the flywheel.

Which instrument is used to check flywheel face out?

Mount the dial gauge magnetic base to the engine flywheel housing. First set the indicator pointer against the friction face of the flywheel near the outer edge (Fig. 2.10(a and b)) and set gauge to zero.

How is flywheel housing runout measured?

Flywheel Face Runout Secure dial indicator base to flywheel housing face. Put gauge finger in contact with flywheel face near the outer edge. Rotate flywheel one revolution. Maximum runout is 0.008″ (0.20 mm).

How do I know if my flywheel is loose?

Loose Flyweel Bolts Torque the bolts in a crisscross pattern according to the manufacturer’s specifications. Loose flywheel or flexplate bolts make a rattling or knocking sound that changes with engine speed. It’s heard behind the engine, where it mounts to the transmission bellhousing.

What are the two instruments used to measure the warpage of the flywheel?

A dial gauge can indicate changes in the target’s warpage or eccentricity in detail. Dial gauges come in two types: the spindle type, which has a stroke of several millimeters, and the lever type, which uses the dial to increase the rotation angle of the cantilever.

What is the spec for flywheel housing face runout?

Maximum runout is 0.008″ (0.20 mm). Secure dial indicator base to flywheel housing face. Position gauge finger so that it contacts pilot bearing bore.

How do you calculate flywheel energy?

Kinetic Energy goes as 1/2*I*w2. For flywheels I =1/2MR2. If we measure w in revolutions per second then the stored energy of a flywheel is approximately 6MR2 x w2 (RPS) For M=140 kg and R=50cm this yields a required w of 500 RPS or 30,000 RPM.

What are the 6 parts of a flywheel?

A flywheel is an energy storage device that is capable of storing kinetic energy in a spinning mass, and the energy stored is directly proportional to the square of the wheel speed and rotor’s mass moment of inertia [36,57]….Flywheel

• Piston.
• Electrochemical Capacitor.
• Flux Density.
• Magnetic Bearing.
• Fuel Cell.
• Compressor.

What is flatness measurement?

When measuring flatness, you are checking for unevenness in the surface, to see how precisely flat a surface is. The most protruding part and the most concaved part must be at a specific distance between two planes that are separated vertically. Sample Drawings. Using a Dial Gauge.

Which tool would you use to measure crankshaft runout?

Feuling Crankshaft Runout Measuring Tool 9015.
