I walked up to the Matco truck. Talked to the Matco man, he never heard of a meteric feeler gauge. He did know the SAE tool has MM on it. The Matco man looked in his book and no meteric feeler he will check into the gauge for me. Anyone have the backlash gear locking pins? As I look at this project I see the backlash gear and I wondered, Are the locking Pins notched or tappered at one end to seat inside the camshaft gear/backlash gear? I want to try and make locking pins from a metal dowel or maybe use an alan wrench to hold the back lash gear??
