New parts hardness testing QA - yamajason - 04-01-2016
Is this just a waste of money when buying parts from a reputable dealer?

If it is available to you, I would. Rockwell testers are great for transmission gear compatibility and any other type of metal against metal compatibility. Especially valuable in rear gear sets, and camshaft - non-roller lifter sets

I would not waste the money... Unless you are building a race truck. Just my .02.

Unless you have control over the whole manufacturing process start to finish and you know what hardness you're looking for the base metal you're using and the hardness of the rollers on your cam followers you have no clue what you're looking at when they give you the numbers and in first place don't even bother it's a waste of money on top of that engine manufacturers spend millions of dollars an engine tests and simulations and have been in that business for many years they know what they need for hardness and the base metals are using so unless you have a full knowledge for all that you're just shooting in the dark just my two cents

How to check hardness? Easy!
Take a file from HF Tools and slide it over the cam lobe. If file is give up hardness is good enough. If you have streaks on the cam lobe - cam is counterfeit.

The problem with a rockwell hardness tester is that it leaves a ding where you did the test.
