How much clearance do your bearings need?

Posted on by Arif Clayton

How much clearance do your bearings need?

As a rule of thumb, main bearing clearance should be targeted between 0.0025- and 0.0020-inch for most street and street/strip engines.

How does a plastic gauge work?

PLASTIGAUGE is comprised of a rod or thread of a compliant plastic material of accurately determined cross-section – either circular or square. The surfaces between which measurement is to be made are first separated, PLASTIGAUGE is inserted (see fig. 2) and the surfaces are returned to their standard position.

What is a plastic wear gauge used for?

Plastic Gauge provides a simple but precise method for the measurement of clearance between fitted surfaces. It is particularly useful for measuring clearance in split bearings or in situations where a feeler gauge cannot be inserted.

How do you check a rod clearance?

Measuring the inside diameter of a main or rod bearing will require a dial bore gauge. The best ones to use are accurate down to 0.0001-inch. With these two tools you can quickly determine the clearances in any engine. Measuring bearing clearance is only valuable if the numbers are accurate so use quality tools.

What is the purpose of plastic gauge?

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.

What kind of engine does a Detroit 60 series have?

This engine comes in 2 configurations: factory reman or in-house reman. The factory reman is remanufactured by Detroit Diesel with all genuine Detroit parts.

What is the model number of a Detroit Diesel engine?

Detroit Diesel Series 60 engines equipped with DDEC II electronic control systems are identified by a “U” in the sixth position of the model number. Example: 6067GU60. Detroit Diesel Electronic Controlled Series 60 engines can be equipped with a variety of options designed to warn the operator of an engine malfunction.

How much clearance do your bearings need?

The Rule of Thumb Generally speaking, bearing clearance should be 0.001-inch for every inch of journal diameter.

What is the connecting rod journal also called?

For extra confusion, the connecting rod journals are abbreviated to rod journals and also commonly called crank pins , or big-end journals . The distance between the center of the main journal and the center of the crankshaft pin is called the crank radius , also called the crank throw .

How accurate is Plastigage?

Tech Tip: Be sure to always use the inch side of the Plastigage package. Most good micrometers will measure down to 0.0001 inch (one ten-thousandths of an inch), which is plenty accurate.

What is a Plastigage used for?

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 measure crankshaft bearing clearance?

For these reasons, bearing clearances are specified as “vertical clearance” and must be measured at 90 degrees to the split line. The best method of measurement is with a dial bore gage that measures the bearing inside iameter when the bearings are installed at the specified torque without the shaft in place.

Why is it important to remove the Plastigage?

Remove the engine sump cover to reveal the big-end and its retaining set-screws. 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.

When the length of connecting rod is small it results in?

When the connecting rod is short compared to crank radius, it possesses greater angular swing which results in greater side thrust on piston. For high speed vehicles the length of connecting rod to crank radius is generally 4 or less.

What do the top two piston rings do?

The top two rings— known as compression rings— are primarily for sealing the combustion chamber. The bottom ring— known as the oil control ring— is primarily for controlling the supply of oil to the cylinder wall, in order to lubricate the piston skirt and the oil control rings.

Does Plastigage go bad?

Does Plastigage go bad? From experience, Plastigauge does have a shelf life and it gets brittle when expired. If your Plastigauge is pliable, use it.
