This little guy holds the flywheel onto the crankshaft. It's a pretty simple part, really – it’s just a bolt, but a very important one. It needs to withstand a lot of force because of all the spinning going on in there. It doesn’t really do anything actively besides secure things. Think of the flywheel as being key to keeping the engine running smoothly. It stores rotational energy, and that screw is what keeps it locked down tight to the crankshaft. Without it, the flywheel could wobble or even come loose, and that’s a really bad situation. It’s deep inside the engine, in the crankcase, so you won’t see it unless you’re doing some serious engine work. It’s critical because if this screw fails, it can cause major engine damage. If the flywheel isn't secured properly, it can throw everything off balance, potentially damaging the crankshaft, bearings, or even worse. You’ll notice if one of these goes bad usually through a lot of vibration or a really rough – running engine, but by that point, the damage might already be done. It’s a cheap part to replace as preventative maintenance, and honestly, it’s worth it for the peace of mind. We have a good selection of these on Fixparts Online, and it’s always best to get a quality replacement. It’s one of those things that acts like a shield—small, but protects a big investment.
