A. Jenkins –
The measurements of the Woodruff keys appear to be very close to specification.Nicely taped storage container prevented shifting of the keys so that all stayed in their respective bins. They were packed with a piece of corrosion paper to prevent rust.I bought these because it was time to maintain my 50 gallon compressor. I wanted to be ready to address any issues with the pulleys.Also, I help people on the side of the road whenever I can. One case involved a 94 Civic with the Woodruff key sheared on the harmonic balancer. I suspect he had not torqued the balancer correctly leading to the failure. The gentlemen had the tools to do the repair but I didn’t have a replacement key. I will be ready next time.
