Ratech 500 Ring and Pinion Gear Marking Compound

Ratech 500 is a specialized gear marking compound designed for proper differential setup and installation. This half-ounce compound comes with an application brush and is essential for checking ring and pinion gear contact patterns during differential rebuilds.

Key Features:

• Professional-grade marking compound for accurate gear pattern verification
• Includes application brush for easy use
• Half-ounce size (0.5 oz) provides sufficient compound for multiple differential setups
• Compatible with all ring and pinion gear sets (GM, Ford, Dana, Chrysler, Toyota applications)
• Essential tool for ensuring proper tooth contact and correct pinion depth

When rebuilding or installing new ring and pinion gears, proper contact pattern is critical for gear longevity and noise-free operation. This marking compound allows technicians to visualize the contact pattern on gear teeth, ensuring correct pinion depth, backlash, and bearing preload before final assembly. Simply apply the compound to several gear teeth, rotate the pinion through the ring gear, and examine the pattern to verify proper setup.
