MECHANICS MAINTENANCE

Every six months a mechanic should perform the following inspection and maintenance.

CVT BELT

1. WARNING Start the mixer and adjust the speed control lever (Figure 1 [9]) to the lowest speed

(speed 1). Stop the mixer.

FOR SAFETY, DISCONNECT THE ELECTRICALPOWER SUPPLY CORD.

2. Remove the top cover (Figure 15 [4]) per section 2 mechanics maintenance “REMOVAL OF

TOP OVER” on page 2.6.

3. Remove the rear access panel (Figure 15 [5]).

4. Inspect the drive belt (Figure 14 [3]). If the belt is excessively frayed or has a heavily glazed

surface, replace it.However it is generally the best judgement to leave a drive belt in the machine

if it is performing well, even if it shows moderate wear. Inspect the gripping surface of the belt

for excessively glazed surfaces or contamination by grease or oil.

5. heck the belt for proper tension. The outer edge of the belt should be flush to 1/16 inch below

the outer diameter of the upper variable speed pulley when the mixer is in speed “1”. If not,

adjust the belt using the “Belt Adjustment” procedure on page 2.2.

6. Start the mixer and shift the speed control from speed “1” to speed “4” and shut the mixer off.

7. heck the position of the belt on the lower vari-speed pulley. The belt should be flush to 1/16

inch below the outer flange of the pulley. If not adjust the belt using the “Belt Adjustment”

procedures on page 2.2.

Page2.1

Check upper

vari-speed pulley

Check lower

vari-speed pulley

BELT REPLACEMENT

1. Run the mixer and shift to first speed “1” and shut the mixer off.

FOR SAFETY, DISCONNECT THE ELECTRICALPOWER SUPPLY CORD.

NOTE MIXERS WITH POWER BOWLLIFT:

Loosen the four 5/16-18 Kep nuts (Figure 12 [11]) and slide the bracket (Figure 12 [16]) all the

way toward the front of the mixer housing and remove the chain (Figure 12 [10]).

2. With the mixer OFF, shift the mixer to fourth speed “4”.

3. Unwrap the belt from the top pulley. Slide the belt between the top pulley and the speed control

cam (Figure 13 [15]).

4. Remove the belt from the lower vari-speed pulley. NOTE: the bowl slide must be in the lowered

position for the belt to clear the nose of the pulley.

WARNING The pulley flanges are spring loaded. Keep your fingers away from the pulley

while removing the belt.

5. Install the new belt in the reverse of the above procedure. Place the new belt around the lower

vari-speed pulley and pull the belt into the pulley to sperate the flanges of the pulley and allow

installation of the belt on the upper vari-speed pulley.

6. Adjust the belt as described below.

BELT ADJUSTMENT

1. Upper Vari-Speed pulley

a. With the mixer in speed 1, loosen the nuts holding the speed control bracket (Figure []), de-

tent housing [] and strap [].

b. If the belt was riding outside the pulley flanges, tap the bracket lightly towards the rear of the

mixer. If the belt was riding more than 1/16 inch below the pulley flanges, lightly tap the

bracket towards the front of the mixer. Shifting the speed control to speed 2 may help.

NOTE Move both the bracket [] and the detent housing [] the same amount. The assembly

must remain perpendicular to the mixer housing or binding of the speed control will result.

c. Retighten the nuts and run the mixer in speed 1 and check the belt position on the upper

pulley. Repeat the procedure if necessary until the belt is flush to 1/16 inch below the upper

pulley flange.

2. Lower Vari-Speed pulley

Once the upper vari-speed pulley is adjusted the lower pulley must be checked and adjusted as

necessary.

Page2.2

d. Start the mixer and shift the speed control to speed 4 and stop the mixer. heck the position

of the belt on the lower vari-speed pulley. The belt should be flush to 1/16 inch below the

outer edge of the pulley flanges.

e. If adjustment is needed, loosen the nuts (Figure []) and raise or lower the motor using the

nuts on the under side of the motor.

NOTE The base of the motor must remain parallel to the base of the mixer. If the base of the

motor is not parallel to the mixer base the belt life will be reduced and the mixer may shift

poorly.

f. Retighten the top nuts and run the mixer in speed 4 and check the belt position on the lower

vari-speed pulley. Repeat the procedure if necessary until the belt is flush to 1/16 inch below

the upper pulley flange.
