Today we make a huge step on the LS1 for the RX-7!! We finish up all the cleaning, and install new main bearings. I go through the torque specs and sequence for all the bolts that hold the crankshaft in! What should we install next??
I was curious do you then put the rod bearings on after what you did cause you mentioned main bearings and I didn’t know where you put the rod bearings at?
Yes that is correct. The main bearings are the ones I installed. The rod bearing attach to the crank in between each of the main bearing caps. I did a video about that process as well.
I did have it honed out to match the piston set as well as a light decking of the block and cylinder heads. In the later videos you can see me getting the rotating assembly balanced, crankshaft polished, and the camshaft journals honed as well.
I got it off the snap-on truck at one of the jobs I used to work at. They go for around 5-600 dollars but they are the best and most consistent to use. If you build more than one engine I'd say it's worth it. You can buy them on their website as well!
Once you torqued the bolts to their yield point, those bolts were permanently stretched and cannot be reused. You technically destroyed those bolts during your initial measurement process after you removed them. You do not need to torque those bolts fully when checking clearances. "Torque to Yield" bolts are just that. They get torqued to their yield point and remain that way until they are removed and then must be replaced. They cannot be reused.
I was about to say if they are torque to yield they need replacement once they are removed. Makes checking clearance extra expensive. That's why I just get ARP studs.
