Precision gauge pins used to measure the outside diameter of cam drive gears. 🔩 🇺🇸
These pins allow technicians to quickly compare gear outer diameters without disassembling the drive, making inspection and fit verification fast and reliable.
- Measure over pins to determine gear size differences across model years.
- The '90-'99 gear range was reduced from .006" to .003", while the large gears match the earlier '84-'89 sizes (green and black codes).
- The '90 manual specifies .108" pins instead of .105"; measurements over .108" pins are approximately .012" larger than over .105" pins.
- On '92 engines, stock cam gears interchange with earlier versions, though some outer diameters were reduced by .025".
Follow the published measurement procedure to confirm gear dimensions before replacement or refurbishment.
