Front Axle Differential Manual Extract

Product Overview

This comprehensive manual aims to guide technicians through the precise procedure of overhauling and adjusting the front axle differential. The detailed instructions provided ensure an accurate setup, suitable specifically for differentials with planet gears consisting of 12 teeth and sun gears having 20 teeth, with a modulus of 4.1.

Key Features

• Precision in Gear Adjustment: Directions to maintain the correct backlash between planet pinions and side gears.
• Comprehensive Measurement Technique: Instructions for accurate end float measurement using a dial gauge.
• Step-by-step Component Cleaning: Ensures enhanced accuracy in measurements by removing oil traces.
• Shim Installation Guide: Details on fitting shims to the calculated values for optimal gear positioning.

Benefits

• Achieve maximum performance of the differential through precise adjustment and installation.
• Maintain prolonged gear integrity and efficiency by adhering to recommended clearances and end floats.
• Avoid unnecessary wear and tear, thereby extending the lifespan of the differential components.

Usage Recommendations

• Ensure all components are thoroughly cleaned to remove oil traces prior to measurement.
• Carefully follow the procedures to measure and adjust the backlash and end float between gears.
• Utilize a micrometer for precise measurement to ensure correct float adjustment.
• Reinstall gear shims accurately as per the instructions to achieve optimal gear clearance.

NOTE: The desired end float for the left and right sun gears should be approximately 0.25 mm (0.010 in). Variations within 0.20 – 0.30 mm (0.0079 – 0.0118 in) will result in a gear clearance of 0.12 – 0.18 mm (0.0047 – 0.0071 in), ensuring smooth operation.
