Group 17 - Beginner Dirt Bike/CDR
We worked on the reassembly of our dirt bike with group 11. Our group was in charge of reassembling the engine and group 11 was in charge of reassembling the frame and everything else.
- Wrench/Ratchet Set
- P12 Screwdriver
Steps to Reassembling
- *See Group 11 for reassembly of frame
- *Difficulty in Table 3 is measured with 1 being easy to reassemble (little effort) and 5 difficult to reassemble (multiple parts and lots of effort).
How the Product Runs
- Our product did not run before we dissected or after we reassembled it. However, the reasons changed slightly. Although there was still no fuel, a piece to the carburetor was also missing. In order for the bike to function, we would just need to add fuel and reattach the piece. The piece was returned late and therefore didn't give us adequate time for testing.
Differences between Reassembly and Disassembly
- A major difference between the reassembly and the disassembly is how the pieces fit together. During reassembly we had to search through our labeled bags of bolts to find which fit the best in each hole. We also had several problems with pieces not fitting back in place, such as the case of the engine block; it was difficult to line up a couple of the intricate parts with the correct part of the casing. This required a trial and error type reassembly which was time consuming but ultimately everything was reassembled properly.
- For the most part the same tools were used. The only difference is we didn't have to use needle nose pliers to pull off tight pieces.
- We were almost able to completely reassemble the engine. The only thing that we didn't completely reassemble was the Carburetor because the piece was missing. However, the piece was returned.
- To build the bike using the same size bolts and screws. If there was a standard size of bolts and screws it would've been so much faster and easier to reassemble and to disassemble.
- To change the position of the oil compartment to aid disassembly.
- To use better connection between the engine block and the transmissions part.
