The ATC J-35906-A Cam Gear Pilot is a precision alignment tool designed for installing and aligning the camshaft gear on Detroit Diesel Series 60 engines, compatible with both early (old) and updated (new) cam gear bolt designs.
During camshaft gear installation, maintaining perfect alignment between the camshaft and gear is critical to ensure proper timing and prevent component damage. The cam gear must be installed squarely onto the camshaft while maintaining correct positioning relative to the timing train.
The J-35906-A functions as a pilot guide, helping center and support the cam gear during installation. This allows technicians to:
- Align the cam gear precisely with the camshaft
- Prevent cocking or misalignment during installation
- Ensure smooth engagement of gear teeth
Improper installation methods can lead to:
- Misaligned cam gear
- Premature gear wear or noise
- Incorrect timing relationship
- Damage to camshaft or gear mounting surfaces
This tool is specifically designed to work with both old and new bolt configurations, making it suitable across different Series 60 engine variations.
