Determine Snap Ring Play
- Install the disc set to the DT 46477
(1) .
- Put the dial gage sensor on the clutch B adjusting ring.
- Feed the compressed air to clutch B via the control valves.
- Set the dial gage to 0.
- Pressurize clutch E via the control valve and read measurement value.
- Repeat the measurement twice with the disc set turned by 120 degrees.
- The average measurement values M1, M2, M3. Measurement value is S.
• | M1 = 0.27 mm (0.011 in), M2 = 0.23 mm
(0.009 in), M3 = 0.25 mm (0.010 in) |
Measuring Installation Space, Clutch B (EB)
- Install the disc set to the DT 46477
(1).
- Put the dial gage sensor on DT 46480
.
- Feed the compressed air to clutch E via the control valves.
- Set the dial gage to zero.
- Lift measurement ring B by hand until it touches the cup and reads the
measurement value.
- Repeat measurement twice with disc set turned by 120 degrees.
- The average measurement values M4, M5, M6. Measurement value is MB.
• | The minimum installation space EB is equal to the height of the ring RB
plus measurement value MB |
Specification
Specification value for the height of the
ring RB is 11.99 mm (0.472 in
• | M4 = 2.36 mm (0.093 in) |
• | M5 = 2.40 mm (0.094 in) |
• | M6 = 2.38 mm (0.094 in) |
• | So, MB = (2.36+2.40+2.38)/3 = 2.38 mm [(0.093+0.094+0.094)/3=0.094 in] |
• | EB = 11.99+2.38 =14.37 mm (0.472+0.094 =0.556 in) |
Measuring Installation Space, Clutch E (EE)
- Install the disc set to the DT 46477
(1).
- Put the dial gage sensor on DT 46481
.
- Set the dial gage to 0.
- Feed the compressed air to clutch E via the control valves.
- Read off the measured value.
- Repeat measurement twice with disc set turned by 120 degrees.
- The average measurement values M7, M8, M9. Measurement value is ME.
• | The minimum installation space BE is equal to the ring height RE plus
ME -- minus snap ring play S. |
Specification
The specification value of the ring height
RE is 20.98 mm (0.826 in).
• | M9 = 2.54 mm (0.100 in) |
• | So, ME = (2.6+2.55+2.54)/3 = 2.56 mm [(0.102+0.100+0.100)/3=0.101 in] |
• | EE = 20.98+2.56-0.25=23.29 mm (0.826+0.101-0.010=0.917 in) |
Determining Adjusting Disc B (PB)
- Install the disc set to DT 46478
(1).
- Using the disc thickness gage, determine thickness ME for the disc set
for clutch B, without adjusting disc, which is located in second highest plate).
- Calculate the test dimension PB - PB = EB - MB
EB = installation space
MB = disc set thickness
EXAMPLE
EB = 14.37 mm (0.566 in)
MB = 11.3 mm (0.445 in)
PB = 3.07 mm (0.121 in)
- Find the disc set's thickness. Refer to
Transmission General Specifications
.
PB is 3.07 mm
(0.121 in) so, the disc set's thickness is 1.8 mm (.070 in).
- Replace clutch B's setting disc 1.8 mm (.070 in).
Determining Adjusting Disc E (PE)
- Install DT 46478
(1).
- Using disc thickness gage, determine thickness MB for the disc set for
clutch E, without adjusting the disc, which is located in the lowest plate.
- Calculate the test dimension PE - PE = EE - ME
EE = installation space
MB = disc set thickness
EXAMPLE
EE = 23.29 mm (0.917 in)
ME = 16.70 mm (0.657 in)
PE = 6.59 mm (0.260 in)
- Find the disc set's thickness. Refer to
Transmission General Specifications
.
PE is 6.59 mm
(0.260 in) so, the disc set's thickness is 5.0 mm (0.20 in).
- Replace clutch B's setting disc (5.0 mm (0.20 in).
