Access and Replace Rod Bearings

What happens here

The presenter and Nathan get underneath the race car to demonstrate how to replace the rod bearings. Nathan explains that the oil pump mounts to the engine block, and the main bearings (which were not damaged in this case) are located at the front of the engine. He then focuses on the rod bearings, which connect the piston to the crankshaft. He shows how to unbolt the two halves of the connecting rod cap, then rotate the crankshaft using a ratchet on the end of the engine to bring each connecting rod into an accessible position. After removing the cap, the old bearing halves can be inspected and replaced. He stresses the crucial step of torquing the bolts correctly to 'stretch' them, ensuring they are securely fastened and preventing them from backing off during high RPM operation (up to 7,200 RPM in this race car). If a bolt is overtightened and stretched beyond its elastic limit, it must be replaced.

Goal: Replace worn rod bearings in the race car engine.
