Fel-Pro 36168 Engine Green and Red Plastigage Bearing Clearance Gauge Kit

The Fel-Pro 36168 (Part# SPGR-1) Plastigage Kit is an essential precision measuring tool for checking bearing clearances during engine assembly and rebuilds. This dual-range kit includes both green and red plastigage strips to cover a wide range of bearing clearance specifications.

Key Features:

• Green plastigage measures 0.025-0.075mm (0.001-0.003 inch) clearances - ideal for rod bearings
• Red plastigage measures 0.050-0.150mm (0.002-0.006 inch) clearances - perfect for main bearings
• Made from special extruded plastic thread with accurately controlled crush properties
• Easy to use - simply place between bearing surfaces, torque to spec, and measure the flattened strip
• Measurement scale printed on wrapper for quick, accurate readings
• Oil soluble material cleans up easily during final assembly

Plastigage provides a fast, reliable, and cost-effective method to verify proper bearing clearances on crankshaft main bearings, connecting rod bearings, and other critical engine components. Essential for professional engine builders and DIY mechanics performing engine overhauls, this tool helps prevent costly failures by ensuring bearings are within manufacturer specifications before final assembly.
