The Clevite MPR1 Cle Plastigage is a crucial component in the engine rebuilding process, specifically designed for measuring the clearance between the crankshaft and connecting rod bearings. This Plastigage product from Clevite is a thin, flexible, and heat-resistant material made of a special thermoplastic compound, which enables it to expand evenly when the engine is running. This expansion is used to accurately measure the clearance between critical engine components.
The Plastigage comes in a compact, rod-shaped form, with the clevis end designed to fit snugly onto the crankshaft end of the connecting rod. Its other end is left plain, allowing it to be easily measured with precision instruments once the engine has been run for a sufficient period of time to allow the Plastigage to expand. This expansion will result in a measurable increase in the length of the Plastigage, which is then compared to the original, un-expanded length to determine the clearance between the crankshaft and the connecting rod bearings.
The MPR1 Cle Plastigage from Clevite is suitable for use in a wide range of applications, making it a versatile tool for engine builders and mechanics. It is recommended for use in both gasoline and diesel engines, and is suitable for use with both aluminum and iron engine blocks. The material's excellent heat resistance ensures that it can withstand the high temperatures generated during engine operation, while its flexibility allows it to adapt to the contours of the crankshaft and connecting rod surfaces for an accurate measurement.
Using the Clevite MPR1 Cle Plastigage is a quick and straightforward process. Simply insert the Plastigage into the appropriate location on the crankshaft end of the connecting rod, ensuring that it is seated securely and making contact with both the crankshaft and the connecting rod bearing. Once the engine has been run for the recommended period of time, the Plastigage will have expanded, allowing it to be easily removed and measured with precision instruments. The clearance measurement obtained from the Plastigage is then compared to the manufacturer's specifications to determine if any repairs or adjustments are necessary.
In conclusion, the Clevite MPR1 Cle Plastigage is an essential tool for engine builders and mechanics, providing an accurate and reliable method for measuring the critical clearance between the crankshaft and connecting rod bearings. Its heat-resistant, flexible, and thermoplastic material makes it suitable for use in a wide range of applications, while its simple and straightforward use makes it an indispensable component of any engine rebuilding process.
Clevite MPR-1 Cle Plastigage is a type of piston ring end gap setting material used to ensure proper piston clearance during engine assembly. Here are some pros and cons of using Clevite MPR-1 Cle Plastigage:
Pros:1. Precise Clearance: Clevite MPR-1 Cle Plastigage provides a precise and consistent clearance between the piston and cylinder wall, ensuring proper engine operation and reducing the risk of damage to the piston or cylinder.
2. Easy to Use: The Plastigage material is easy to use and can be removed after the engine has been run for a short time. This makes it a convenient option for DIY engine builders and mechanics.
3. Cost-Effective: Compared to other methods of setting piston clearance, such as using feeler gauges or measuring devices, Clevite MPR-1 Cle Plastigage is a cost-effective solution.
4. Durable: Clevite MPR-1 Cle Plastigage is made from high-quality materials that can withstand the heat and pressure of an engine. This ensures that it will last for multiple engine builds.
Cons:1. Limited Use: Clevite MPR-1 Cle Plastigage is only suitable for setting the clearance between the piston and cylinder wall. It cannot be used for other types of clearance measurements in an engine.
2. Temperature Sensitivity: The Plastigage material can be affected by temperature, which can impact the accuracy of the clearance measurement. It is important to follow the manufacturer's instructions carefully to ensure accurate results.
3. Disposable: Once the Plastigage material has been used to set the clearance, it cannot be reused. This means that it is a consumable item that will need to be replaced for each engine build.
Conclusion:Clevite MPR-1 Cle Plastigage is a useful tool for setting the clearance between the piston and cylinder wall during engine assembly. Its precision, ease of use, and cost-effectiveness make it a popular choice among engine builders and mechanics. However, its limited use, temperature sensitivity, and disposability are important considerations to keep in mind. Ultimately, whether or not to use Clevite MPR-1 Cle Plastigage depends on the specific needs and resources of the engine builder or mechanic.
Recommendation:If you are building or working on an engine and need to set the clearance between the piston and cylinder wall, Clevite MPR-1 Cle Plastigage is a reliable and convenient option to consider. However, it is important to follow the manufacturer's instructions carefully to ensure accurate results and to consider the cost-effectiveness and disposability of the material in the context of your project. If you have the resources and expertise, other methods of setting piston clearance, such as using feeler gauges or measuring devices, may be more suitable for your needs.
This does not replace properly measuring crankshaft journals, housing bores, or bearing dimensions before engine reassembly with accurate micrometers and gauges. Clevite Plastigage Red - 12 Pack, is designed as a final check of total vertical oil clearance during reassembly.
