4-5. REEL DISK REPLACEMENT AND HEIGHT

CHECK

• Removal
1. Remove the cassette housing control assembly.
2. Pull the tension band out of the tension arm ass'y.
3. Remove the Supply/Take-up main brake ass'y.
4. Open the hook at the top of the reel disk, and remove the

reel disk.

Note:
Take care so that the tension band ass'y and main brake
ass'y (especially soft brake) are not deformed.

4. Assemble the Supply main brake ass'y.
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 4-6.

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.

Figure 4-4.

Note:
When the tension band ass'y is pressed in the direction of
the arrow for removal, the catch is hard to be deformed.

Figure 4-5.

• Reassembly (Supply reel disk)
1. Clean the reel disk shaft and apply grease (SC-141) to

it.

2. Match the phases of reel disk and reel relay gear, and set

the new reel disk.

3. After checking the reel disk height, wind the tension

band ass'y around the reel disk, and insert into the hole
of tension arm ass'y.
