Removal
1. Remove the cassette housing control assembly.
2. Remove the Supply/Take-up main brake ass'y.
3. Pull the tension band out of the tension arm ass'y.
4. Remove the reel disk.
Note:
Take care so that the tension band ass'y and main brake
ass'y are not deformed.
Notes:
1. When installing the reel disk, take due care so that the
tension band ass'y is not deformed and grease does no
adhere.
2. Do not damage the Supply main brake ass'y. Be careful
so that grease does not adhere to the brake surface.
• Reassembly (Take-up reel disk)
1. Clean the reel disk shaft and apply grease (SC-141) to
it.
2. Align the phase of the reel disk to that of the reel relay
gear and to install a new take-up reel disk onto the shaft.
3. Check the reel disk height and reassemble the take-up
main brake ass'y.
Note:
1. Take care so that the Take-up main brake ass'y is not
damaged. Take care so that grease does not adhere the
brake surface.
2. After reassembly, check the video search rewind back
tension (see 4-10), and check the brake torque (see 4-
14).
• Height checking and adjustment
Note:
1. Set the master plane with due care so that it does not
contact the drum.
2. When putting the master plane, shift the reverse guide
a little in the loading direction. Care must be taken since
excessive shift results in damage.
Figure 4-4.
Note:
• Check that the reel disk is lower than part A but higher
than part B. If the height is not correct, readjust the reel
disk height by changing the poly-slider washer under the
reel disk.
