Harmonic Balancer Install Question
1-What do I use to measure the depth of the nose of the crankshaft in the bore of the harmonic balancer? The digital micrometer I have doesn’t really work for measuring depth.
2- When I removed my stock HB bolt, there was an oily substance behind the bolt in the crank. It seemed lightweight to be engine oil, but it was dark. I am pretty certain this was the first time the HB bolt had been removed as there was a ton of orange-looking thread lock all over the threads and head of the bolt. Thoughts?
