Day 3- Emily
Introduction
- Met John who was sick! Tech support and lab manager.
- Went over groups and what we did last shop:
o Carborator- missing a few parts, hard to salvage, couldn’t find a manual BUT Littman has a tub of old/new carborators! Try out carb on another bike so to learn how to take it off and put it back on.
o Arbour press to remove pin from swing arm and bushings because was so rusty. Used socket to stabilize on press.
o Took apart clutch and transmission, bagged and named parts. Friction plates in good condition. TO DO: Inspect all parts with John.
o Took apart base part of engine
o Fork assembly and categorization, used three jaw chuck in lathe to grip round fork to loosen and pull out spring.
o Wheels- measured wheel offset, important so that chain does not hit tyre. Offset is determined by how the spokes on the wheel are assembled. Took tyres off wheel frame.
o 2 full piston turns for one valve turn. Cam shaft, make engines work better at high or low RPM’s- valves overlap meaning they will both open at the same time- bad for efficiency but is better for scavaging (higher RPM’s).
o Sprockets- condition is based on how symmetrical they are not how clean they are.
- New manual for Quartermasters- Manual 8, closer to the manufacture time of our bike
ZAMM Chapter 3,4,5
- Discussion leader- Noelle
- Motorcycle references (3)
o Tack- measures RPM (revolution per minute of the crankshaft), engine speed. Tack is helpful for gear changing so we can keep track of what the engine is doing. Red line. We have a Speedometer on our bike, measures wheel speed.
- Content (3)
o Metaphor of ghosts- compare idea of laws of science to ghosts, they are both in our head, fantasies, philosophical arguments. Did gravity exist before Newton? Yes, but did the law exist? The law is a human invention, it still existed before the interaction. Ghost like. Related to Plato’s cave analogy.
o Phadreus- all of the thoughts he was thinking that day were not his. Split personality becomes evident. Shock therapy erases some memories, hence the fact he remembers the road and the motel. We cannot be 100% certain that he has been here before, but we can infer this.

o Tools kits:
- Large adjustable open-end wrench
- Ball peen hammer- peening= making a surface rough, strengthens the surface so it is not as loud.
- Cold chisel- used for going into metal (score marks)
- Taper punch
- Tyre irons- used to get under tyre to pull off rim. Hook for leverage.
- Molibdenum spray- penetrating lubricant, seen in the shop (YIELD)
- Impact driver- combines a forward action from a hammer into a quick rotation to loosen or tighten
- Point file- points are metal contacts made of tungsten, when they separate they make a spark. File for filing the points to make them square as sparking vaporises the metal.
o Spare parts:
- Plugs- spark plugs
- Throttle, clutch and brake cables- adjust carborator, release clutch for free wheeling, for the brakes
- Chain coupling link and keeper- clip must be in the right direction so that the chain does not fall apart if it snags on anything
- Cotter pins- metal pin used to fasten two things together
o Chilton’s motorcycle guide mentioned in book is on Blackboard
- Content (4)
o Motorcycle having a personality- each bike even though it is made the same way, responds differently and feels different. Subtle differences in each bike.
o Relationship between Narrator and John- see first moment of active fun with ‘chicken man’ moment. Talks about capturing moments and how once a border is put on it its gone.
- Motorcycle references (5)
o Shimming handle bars- shim stock, using layers of material to stabilize something. In this case, the handlebars are loose and cannot be tightened. Wants to put a shim to make the diameter of the bars bigger so they are tighter. John is ‘above’ this, bought an expensive motorcycle and does not want to taint it with a beer can.
o Nickel and dime sounds- lots of moving parts in an engine, sound comes from things moving around inside the engine. Especially true of old engines.
- Content (5)
o Reality and John’s reality- building up idea of dichotomy between art and science. Get the idea that the Narrator values science above art, this will mature throughout the book, thinks people should know how bikes work.
o Chris revelation- Chris has a mental illness, doesn’t want to seek treatment. Backstory as to why John is travelling with his son rather than his wife as he is worried about his son and sees this as a bonding episode.
o Talks about John not trusting technology but doesn’t want to seek treatment for his son- double standard?
o Phadreus- inadvertently shows value that Phadreus’ character brought.
