2 BEGINNING MAKE SURE YOU 1. WILL BE ABLE TO RETURN THE TOOLCART to its ORIGINAL CONFIGURATION [ie, study the toolcart] 2. Know how to use all the tools [ASK if you are not sure] 3. KNOW WHAT YOU ARE LOOKING FOR [as in DATA and RESULTS] 4. Have safety glasses 5. Are aware of the dangerous steps 6. Have a plan for any difficult steps 7. Have necessary cleaning materials Lets begin! Manual Transmission

3 Transmission Manual Transmission 3

4 Remove housing bolts Manual Transmission 4

5 You may need to use pry bars and screwdrivers to remove cover Manual Transmission 5

6 Reverse gear mounting bracket Manual Transmission 6

7 Remove reverse gear mounting bracket bolts Manual Transmission 7

8 Remove reverse gear mounting bracket bolts Manual Transmission 8

9 Remove reverse gear Manual Transmission 9

10 Shift mechanism access cap Manual Transmission 10

11 Remove shift mechanism access cap Manual Transmission 11

12 Remove differential subassembly This process involves several steps Manual Transmission 12

13 Operation Remove ring gear Manual Transmission 13

14 Manipulate shifter linkage to observe motion Manual Transmission 14

15 Remove shifter mechanism bolts Manual Transmission 15

16 Remove shifter mechanism bolts Manual Transmission 16

17 STOP NOW ask an instructor, programmer on duty [POD] or technician to supervise the next step. Failure to do this will result in a 5 MARK PENALTY in the performance grade. Manual Transmission

18 Remove shifter mechanism (slide out) Manual Transmission 18

19 Keep your finger on the hole to prevent ball and spring from being launched Manual Transmission 19

20 Do not lose any of the small parts Manual Transmission 20

21 Remove differential subassembly Manual Transmission 21

22 Examine differential subassembly Manual Transmission 22

23 Examine shifting mechanisms Manual Transmission 23

24 Observe motion of different parts Manual Transmission 24

25 Bonus: what is the physical difference between a Spur gear and a Helical gear? Observe Understand the different mechanisms Sketch parts (i.e gears, bearings) Manual Transmission 25

26 Observe Understand the different mechanisms Sketch parts (i.e gears, bearings) Manual Transmission 26

27 MIDDLE You have finished disassembly Make sure you have 1. Accumulate as much data as possible 2. Analyze and synthesize as many results as possible 3. CLEANed and ORGANIZed before resuming assembly Now on to reassembly Manual Transmission

28 Replace gear assemblies Manual Transmission 28

29 Replace gear assemblies Manual Transmission 29

30 Ensure mating parts line up and smooth rotation is possible Manual Transmission 30

31 Replace differential subassembly Manual Transmission 31

32 Replace differential subassembly Manual Transmission 32

33 STOP NOW ask an instructor, programmer on duty [POD] or technician to supervise the next step. Failure to do this will result in a 5 MARK PENALTY in the performance grade. Manual Transmission

34 Replace PART (For more details see step 36 & 37) Manual Transmission 34

35 Adjustment will be required to successfully insert the ball and link (For more details see step 36 & 37) Manual Transmission 35

36 Clarified view of the PART Manual Transmission 36

37 Replacing the ball and link may be difficult and might require several minutes Manual Transmission 37

38 Replace shifter mechanism Manual Transmission 38

39 STOP NOW ask an instructor, programmer on duty [POD] or technician to supervise the next step. Failure to do this will result in a 5 MARK PENALTY in the performance grade. Manual Transmission

40 Bonus: what is the purpose of the ball and spring? Use a screwdriver to hold down ball and spring Manual Transmission 40

41 Slide in shifter mechanism Manual Transmission 41

42 Pliers may be required to rotate and slide the shaft Manual Transmission 42

43 Replace shifter mechanism bolts Manual Transmission 43

44 Replace shifter mechanism bolts Manual Transmission 44

45 Replace reverse gear and shaft Manual Transmission 45

46 Reverse gear located behind differential subassembly Manual Transmission 46

47 Replace reverse gear mounting bracket and bolts Manual Transmission 47

48 Operation Replace ring gear Manual Transmission 48

49 Ensure gears are properly engaged Manual Transmission 49

50 Replace transmission housing and bolts Manual Transmission 50

51 Ensure no optional parts remain on workbench Manual Transmission 51

52 END BEFORE YOU LEAVE Make sure you have 1. CLEANed and ORGANIZed your area. 2. Returned all tools as you found them. 3. HAD YOUR DATA SHEETS SIGNED for AUTHENTICITY TIME FOR A NAP Manual Transmission
