Crankshaft Refurbishing
Many of you have seen this one before. I apologize if bringing it back offends anyone. Domestickilla gave me a crankshaft, and it's a nice one that I want to clean up and use again. You'll be seeing a lot of it and because of this, this video deserves to be here. I fixed what I broke, and this was my experience. In this video Ballos Precision Machine demonstrates magnetic dye penetrant testing, crankshaft polishing and inspecting the balance of a "butchered" 4g63 6-bolt crankshaft.

Crankshaft Balancing Counter Weight Reduction
This big block Chevy engine is getting a trim job on the crankshaft counter weights because we are installing some .400" longer connecting rods with some very light forgerd pistons. We had to remove a total of 400 grams to get the crankshaft to balance correctly.

Block Preparation Part 1
Preparation for powder coating and Glyptal application. Audio track is an original performance by Rojo Del Chocolate. My block is being powder coated rather than painted. It's just something I do. The GSX had it on the last block so it's getting it again. Since the tools are so similar and the mess is the same, I'm going ahead and preparing it for the Glyptal application as well. These 2 coatings will require being baked separately. The powder coating is baked on at a hotter temperature than the Glyptal, so it's going first. The surface preparation instructions for Glyptal is as follows: Surface to be painted should be dry and free from dirt, wax, grease, rust and oil. Remove all grease and oil by washing surface with mineral spirits. Wipe or scrape off all loose dirt, rust or scale. The last sentence is what's covered in this video. The 2nd sentence happens next (although it's already degreased), and I'll get it back from powder coat with it in the state described in sentence #1 completed. If following these instructions to the letter of the law. Second and third opinions in... the main journal is fine. You'll notice that I didn't coat the main caps, or "suitcase handles". I'm not going to. You bang around on these installing and removing them, and I don't want to risk chipping them once they're coated. They're below the windage area, and there will also be an un-coated main bearing girdle down there. This video covered 25 hours of actual work. Yes, I kept changing into the same filthy clothes every shoot because I wanted it to look consistent. You have to take your time doing this kind of work, and be VERY VERY CAREFUL! If for some reason you're crazy enough to attempt what I do in this video, you do so at your own risk. This is an elective treatment that I've never done, but I am by no means the first person to do it. I'm learning about it just like the rest of you.

Blueprint 104 - The Crankshaft
It's important to know what you've got even before dealing with the machinist. If you want to inspect a crankshaft, this is how you do it. I detail the process of removing the crank and what to measure. All specifications in this video are illustrated with a 6-bolt 4g63 turbo block, but are all actually the same for 7-bolt engines with the exception of the rod widths.
