Product Reassembly Plan for Group 26
Product Reassembly Plan
The process for reassembling the pressure washer is almost the same process as disassembling although it in reverse. If one can disassemble it, one can reassemble without much hassle.
Does your product run the same as before you dis-assembled it?
- After re-assembly the engine continues to move with hand cranking as it did when we received it. There are some minor issues which would prevent it from running at this time. Damage to several gaskets (which appeared to be aged to begin with) and a lack of oil which was removed and disposed of during dis-assembly. As well several hoses were misplaced. Getting the product into a working state should be as simple as adding new oil into it, new gaskets and replacement hoses.
What were the differences between the disassembly/reassembly processes?
- The disassembly/reassembly processes were mostly the same for our group. When the product was being disassembled, our members took precaution to write down the correct sequence of events if they made any mistakes so that others would not have the same problems.
- Almost the same set of tools was used during the reassembly process. The only tool that was not needed was the rubber mallet. The tools necessary are a basic metric socket set (only the 8mm, 10mm, 12mm, 13mm, and 22mm sockets are needed), and open-end wrenches. The optional pair of pliers can also be used but the funnel is not needed any more to drain the oil from the engine.
- Our group was able to reassemble almost the entire product. The engine is reassembled and mounted back onto the frame. We are just missing a couple of hoses.
Are there any additional recommendations your group would make at the product level (operation, manufacturing, assembly, design, configuration, etc.)?
- One design change which would increase the life of the pressure washer would be to have any exposed metals either covered with plastic shielding, or coated with a highly durable paint. This would reduce rusting and other damage to the engine and washer in general, extending its operational lifetime. This would require a fairly minimal cost increase weighed against a good potential lengthening of the products life.
- During dis-assembly of the product, we noticed that several of the gaskets were in poor condition. A sturdier material for the gaskets may be in order, as well as a slight increase in the width of walls to better prevent them falling apart. Again this would increase costs slightly, but should also improve the functional life of the product.
