We've disassembled our Mack engine and taken out a piston and cylinder liner. Everything went well but when we tried to take the cylinder liner out we ended up cracking it. As you can see in the picture the bore tapers and we had a puller that fit on the top of the liner but not the bottom. After we heard it crack (which didn't take much by the way) we stopped and tried to figure out what went wrong. The liner actually needed a custom puller made for it that Jeff had fabricated. We also had some trouble getting out the injectors because we didn't know that you had to slide out the rest of the fuel system first.

| Look at the rust on these passages from sitting. |

| Our cracked cylinder liner. |

| Our piston before removing from the engine. The rings lying on top are called "fire rings" |

| Bore for the cylinder liner. |
 |
| Bore tapers so the bottom is actually smaller than the top. |
 |
| Piston, rod, rodcap, and cap bolts on the table. |
 |
| Our head off the engine with the valves still inside of it. The headgasket is lying on top. |
 |
| Exhaust side with the gaskets still on. Look at the heat marks on the studs. That's how hot this gets. |
