B-Series Camshaft Woodruff Key

B-Series Camshaft Woodruff Key

This precisely machined Woodruff key fits into the camshaft timing gear slot to lock the cam gear to the camshaft on Honda B-series engines. It ensures accurate cam timing by preventing the gear from rotating independently of the shaft, which is critical for proper valve timing and engine performance. Over time, worn or damaged keys can cause timing slip or improper alignment during assembly. Replacing this key during timing belt or cam gear service helps maintain accurate cam timing and long-term engine reliability.
