*Always check the unit system and grade of replacement fasteners. Using metric instead of SAE threads, for example, is not in any way acceptable, nor is using ungraded or the wrong grade fasteners. Use caution if using a different fastener strength grade (i.e. using a Grade 8 instead of a Grade 5 fastener); "stronger" isn't necessarily "better". Always use the fastener designated appropriate for your application. Using the wrong fastener could compromise the engine, its parts and/or put one at risk. In some instances, using too "strong" of a fastener may do more harm than good because they were intended to break before serious engine damage could occur. | *Always check the unit system and grade of replacement fasteners.

| + | ===Rod and caps=== | ||
| + | Remember to follow the manufacturer's cylinder numbering system unless they were numbered differently by you or someone else- not all engines had the rods numbered from the factory. | ||
| + | |||
| + | Even if the rods aren't numbered you can still orientate them correctly for what side they go on. This can be done several ways: | ||
| + | *If the pistons are on the rods, they'll have an arrow or notch. This faces forward. | ||
| + | *If you install a rod bearing into the rod and cap, you'll see that it is positioned with one side futher away from the face of the rod/cap. That side faces the crank cheek. Most times the larger chamfer also faces the crank cheek; smaller chamfer faces the other rod on that journal. | ||
| + | *Numbers face the pan rail. | ||

| + | {{Warning}}This has to be correct or severe enginedamage can occur. | ||
