Which tool would you use to measure crankshaft runout?
Feuling Crankshaft Runout Measuring Tool 9015.
What is Cam runout?
Run-out or runout is an inaccuracy of rotating mechanical systems, specifically that the tool or shaft does not rotate exactly in line with the main axis. Radial run-out will measure the same all along the main axis.
How is crankshaft runout measured?
The amount by which a crankshaft is bent. Runout is checked by supporting the crankshaft in V-blocks or rollers and mounting a precision dial indicator so its arm rides the end of the crankshaft as it is rotated. Runout is measured in thousandths of inches.
What is Plastigage used to check?
Plastigage (also called Plastigauge or Plastic Gauge) is a measuring tool for measuring plain bearing clearances, especially in engines. Plastigage is also used to measure clearances on marine drive-shaft bearings, turbine housing bearings, shaft end-float, pipe flange clearances and pup and pressure system bearings.
What is flywheel cupping?
If so, your flywheel needs to be resurfaced. Glazing and discoloration are signs of wear and can prevent it from meeting the clutch smoothly. “Cupping” is caused by the interior surface of the part being worn down by constant contact with the clutch.
What is crankshaft end float?
Definition of ‘end float’ End float is the amount by which a shaft can move lengthwise. The lubricated grooves allow the hubs to shift if shafts are misaligned or subject to end float.
What are the name of the two measuring tools used for crankshaft straightness & Journal sizes?
Measure the outside diameter of the crankshaft main and rodbearing journals using a micrometer. [Figure 10-11] Internal measurements can be made by using telescoping gauges, and then measuring the telescoping gauge with a micrometer.
