Gate 2: Preliminary Design Review
Causes for Corrective Action
The dissection of the GM V-6 Engine went very smoothly with a few minor problems. Our project plan worked out exactly as planned. The dissection took three weeks, and everyone was able to be at the lab on Wednesdays after class to work for an hour to an hour and half. The biggest challenge faced was setting up a time with the group thirty-four, and communicating with them at first. To overcome this, Meredith Canty from our group and Parth Kalia from group thirty-four exchanged emails since both are project managers. Both groups met at five on Wednesdays to work together on the dissection of the engine.
While dissecting the engine the groups realized that there were tools that needed to be acquired that were not offered in the lab to finish the dissection. The two tools needed were the pulley puller and the valve compressor. To get the tools needed, group thirty-four did not really offer any communication or effort into getting them. So it was left up to our group to find the tools. Andrew went to see if the Society of Automotive Engineers had the tools, and if we could use them. However, their tools were specially designed and could not be used, so Meredith tried to see if her father’s business had the tools. Her father’s business did not have them so Brett went home and got the tools needed to finish off the dissection.
Once we had the tools, the valve compressor was used to remove the valves. Then we went to use the pulley puller and realized the bolts were not long enough. To fix the problem, Brett and Derek went to Lowes to buy longer bolts. The bolts worked and the dissection was completed on Monday October 26th. For the small problems that did occur, every member was willing to help out and resolve it as fast as possible to get the dissection done in time. The group works very well together and there are no problem areas in the group.
Product Dissection Plan
The table below documents the procedure that was taken to dissect a GM V6 engine. Each step includes the part that is to be removed, which tool(s) will be used, and how difficult the step is on a scale of 1 to 5. Any additional concerns about removing the part are made in the "Notes" column.
Difficulty Scale
| 1 |
Quickly and easily removed by hand |
| 2 |
Quickly and easily removed using tools |
| 3 |
Easily removed, but time-consuming or repetitive |
| 4 |
Required moderate force, skill, or special tools |
| 5 |
Required excessive force and time |
The Dissection Process
