Vehicle Fitment

Clevite Plastigage (MPY1) provides a reliable, precision method for performing a final check of total vertical oil clearance during engine reassembly. This yellow-coded gauging material allows technicians and engine builders to verify bearing fitment before final torque-down, ensuring the lubrication system operates within required tolerances.

Designed for professional use, Plastigage acts as a critical secondary verification step. It identifies potential assembly errors or out-of-spec components that might be missed during initial measurements. Note that this tool is intended for final verification and does not replace the need for measuring crankshaft journals, housing bores, or bearing dimensions with precision micrometers and dial bore gauges during the machining phase.

• Brand: Clevite
• Series: Plastigage
• Manufacturer Part Number: MPY1
• Color Code: Yellow
• Quantity: 12 Pack
• Function: Measures vertical oil clearance for main and rod bearings

Clevite Plastigage Green (MPG1) offers a proven, cost-effective method for the final verification of total vertical oil clearance during engine reassembly.

While Plastigage is an industry-standard tool for validating assembly tolerances, it is designed as a secondary check. It should be used in conjunction with—not as a replacement for—precise measurements of crankshaft journals, housing bores, and bearing dimensions taken with micrometers and dial bore gauges.

• Manufacturer Part Number: MPG1
• Color Code: Green
• Quantity: 12 individual measurement strips
• Function: Measures vertical oil clearance for main and connecting rod bearings
