Additional Thickness Liner Shims for Caterpillar 3306 Spacer Plate Engines |
|
The AERA Technical Committee offers the following information regarding additional thickness shims for Caterpillar 3306 spacer plate engines. This information should be considered anytime block work is being attempted. This bulletin is in addition to TB2959 which was published several years ago. The machinist is reminded of the goal of obtaining cylinder liner protrusion of .0013-.0069” (.033-.1754 MM) for all liners with no more than .002” (.050 MM) difference between adjacent liners. The counterbore depths should be averaged making 4 measurements of each liner and those measurements should not vary by more than .002” (.050 MM). |

Crankshaft Installation for 2007-2021 Detroit Diesel DD13, 15 and 16 Engines |
|
The AERA Technical Committee offers the following information regarding the crankshaft installation process for 2007-2021 Detroit Diesel DD13, 15 and 16 engines. While the installation procedures are similar for all three engines, it’s important to note that three unique crankshafts are used. Description and Operation of the Crankshaft: The crankshaft is made from induction-hardened steel. The crankshaft bearing journals and connecting rod journals are hardened in the boundary layer and then ground. To avoid vibrations, counterweights are cast onto the guideways. The crankshaft is mounted with seven crankshaft main bearing journals in the cylinder block. There are oil holes located at the crankshaft main bearing journal and the connecting rod journal for lubrication. |

Using Technology as an Engine Training Tool |
|
Just like the changes in engine technology that you see coming through the shop door, nothing stays the same for very long. The same can be said about how we learn; technology has allowed more options to accommodate our busy lifestyles with both online training programs and webinars. For instructors in a classroom environment, technology helps keep students engaged and makes teaching and learning more meaningful and fun. Since almost everyone carries a mobile device these days, online learning has allowed schools the ability to offer blended training platforms that allows the students the flexibility to not only learn at their own pace, but also helps to free up valuable classroom time to allow for more hands on training in the shop. For those individuals already working in the industry, online training courses can be taken anytime, anywhere, everyone can access training no matter the location, the only requirement is an internet connection. |
