Crankshaft Pulley Key 4-Pack - Fit Honda 90704-634-000 - Compatible with Civic, Accord, Integra, CR-V & More
This reliable 4-piece set is a direct aftermarket replacement for the genuine Honda OEM crankshaft pulley key (part #90704-634-000, Key 4.5X11.0).
This small rectangular parallel key is essential for securing the harmonic balancer / crank pulley to the crankshaft, preventing rotation slippage that can lead to misalignment, timing belt failure, or serious engine issues.
Why Choose This 4-Pack?
Timing belt changes, crank pulley upgrades, or full engine rebuilds often require 1-2 keys per job – extras cover mistakes, future projects, or backups.
Buying in a set saves time and money compared to dealer singles!
