What does a PLASTIGAUGE measure?

What does a PLASTIGAUGE measure?

Plastigauge is highly effective for measuring the clearance in large bearings which include Marine Drive Shaft bearings, Turbine housing bearings, Pump and Pressure System bearings. Flatness and clearance in pipe-flanges and cylinder heads are readily checked and measured with standard Plastigauge.

How do you PLASTIGAUGE a bearing?

Tear off a piece of plastigage. Open the paper to remove the plastigage, and place the plastigage across the surface of crankshaft. Position the plastigage in the center of the journal surface. Install the bearing cap and torque the bolts to specification.

Where and how would you use Plastigage?

Plastigauge is a measuring tool used for measuring plain bearing clearances, such as in engines. Other uses include marine drive shaft bearings, turbine housing bearings, pump and pressure system bearings, shaft end-float, flatness and clearance in pipe-flanges and cylinder heads.

How do you remove Plastigauge?

Ideally you should remove the PLASTIGAUGE stripe with a clean oily cloth or industrial de-greasing solvent, but users may be assured that any PLASTIGAUGE left behind is oil soluble and cannot harm the engine in any way.

How do you remove Plastigage?

What color is Plastigage?

What is Plastigage — should it be used – and if so, how do you use it? Plastigage is an accurately made round plastic thread with known deformation properties. It comes in three diameters and colors. It is color coded by size — green Plastigage measures the range .

How do you check bearing crush?

By checking the ‘bearing crush’ the quality of bearing fit is ascertained. Undo and remove one bolt (either one) and, starting with a 0.075mm/ 0.003in feeler gauge, see if the feeler gauge will go into the gap between the cap and block. By using a range of feeler gauges the exact size of the gap can be determined.

What is the difference between bearing crush and bearing spread?

Bearing spread and bearing crush: Bearing shells have a slight larger arc than that of the bearing house. This difference makes shell about 0.005 to 0.02 inch wider than that of the housing bore. Bearing spread comes in use to hold the bearing shell in housing when the engine assembly is performed.

What’s the proper way to use a plastigage?

Plastigage, How to use. Plastigage, How to use. For many years now, there are still a lot of people that don’t know how to use Plastigage, to check the amount of clearance they have in a bearing they want to reset. The instructions say to clean the crankshaft, and bearing before you use the Plastigage.

Which is the most common application of Plastigauge?

Perhaps the most widely used application of PLASTIGAUGE is in the measurement of clearance in plain automotive bearings. This application is described in detail: Remove the engine sump cover to reveal the big-end and its retaining set-screws.

How do you release the big end of a Plastigauge?

Remove the engine sump cover to reveal the big-end and its retaining set-screws. Remove surplus oil and release the big-end shells by unscrewing the set-screws. Apply a smear of grease to the journal and small quantity of silicone release agent to the shell.

What should I use to remove Plastigauge from my car?

Ideally you should remove the PLASTIGAUGE stripe with a clean oily cloth or industrial de-greasing solvent, but users may be assured that any PLASTIGAUGE left behind is oil soluble and cannot harm the engine in any way. home | about | how it works | price list | order online | contact us
