49.6. Disassembly and Reassembly

(fig. 23.4)

a. General. The preferred disassembly sequence is shown in b

below. However, this sequence can be altered to reach a specific part

for replacement purposes. Do not attempt to replace any part until

it is completely accessible.

b. DisassembIy.

(1) Remove the bottom cover (1) which is secured by four screws

(2) and flat washers (3).

(2) Remove hexagonal nut (4) and lockwasher (5) and separate

the mounting clamp and clamp post assembly (items 6 through

11) from the base plate assembly (35).

(3) Tap out the roll pin (6), and remove, as required, the re-

maining parts of the mounting clamp and clamp post assembly

(7 through 11).

(4) Remove the top cover (12) which is secured by five screws

( 13) and flat washers (14).

Caution: Be very careful when removing the top cover to

avoid breaking.

(5) Variable resistor (15), switch (16) and the diode (17) are

mounted to the top cover. Unsolder as required. Tag the

wires to insure proper replacement. Remove the knob (36),

hexagonal nut (37), and flat washer (38) that secure the

variable resistor; remove the collar (39) and hexagonal nut

(40) to remove the switch.

(6) With a screwdriver, slip the drivebelt (18) off the motor

pulley (25).

(7) Remove three retaining rings (19), and lift off three rollers
