At the start of each class:
- Unlock toolbox. Your team is responsible for any
missing tools at the end of the day.
- Mount your engine on the mounting plate. It's ok to use just 2 or 3 bolts.
- Make sure you have a Masonite sheet over your worktable.
- Put rags over your work area too to absorb any oil.
- Get a copy of the engine manual from the TA or instructor.
- Locate the following tools in your toolbox:
- All three socket drives (big, medium, small)
- 1/4" socket
- 5/16" socket
- 3/8"socket
- 1/2" socket (long)
- 15/16" socket
- 13/16" spark plug socket
At the end of each class:
- Remove the engine from the mounting plate
- Make sure all tools have been returned to the box (i.e., no empty tool
slots).
- Lock toolbox
- Replace the mounting plate and the bolts where you found them
- Put engine in the tray and on the shelf
- Wipe any oil off the table
Rules to live by:
- OPEN ONLY ONE DRAWER AT A TIME, or the toolbox could fall on you.
- WATCH FOR SHARP EDGES, especially around the open crankcase. You could get
a nasty cut.
- USE NO METRIC SOCKETS, even if they seem to fit. They don't.
- KEEP TRACK OF YOUR TOOLS. They are your team's responsibility.
