REMOVING EXISTING DRIVE

CAUTION

MAKE SURE ELECTRICAL POWER IS TURNED OFF.

1. Disconnect electrical wiring to drive unit.

2. Refer to page 2-4 of Service Manual for Modular

Dishwashers, for instructions on removing existing drive

unit.

3. Remove bolts and nuts securing drive to table and lower

drive unit to floor. Remove existing drive unit.

4. Remove both front and back drive supports (W-2-14148).

(See fig 1.)

Figure 1. Removing Drive Supports

5. Using a grinder with a cutting disc remove the existing

chain guide (3/16" x 1/2" strip) welded outside the

tables. (See fig 2.)

INSTALLING NEW DRIVE UNIT

1. Determine if machine has clockwise or counter-clockwise

conveyor. Follow directions in fig 3 for drilling holes in

clockwise conveyor, fig 3A for counterclockwise conveyor.

Figure 2. Removing Chain Guide Welded to Table

Figure 3. Drilling Locations for Clockwise Conveyor

2. Run additional threads on all four of the existing rail

studs AS CLOSE as possible to the bottom of the

table. Use the 3/8"-16 thread die (W-0-95576) provided

in the kit. A large adjustable pliers or pipe wrench can

be used to run the thread die up the studs. (See fig 4.)

(A) CLOCKWISE MACHINE

Pack a large amount of silicons sealant around

the 2 studs on the left. Place a split lockwasher

and nut on each stud and securely tighten.

(B) COUNTERCLOCKWISE MACHINE

Pack a large amount of silicone sealant around

the 2 studs on the right. Place a split

lockwasher and nut on each stud and securely

tighten.

Figure 4. Threading Rail Studs

3. Cut off the excess amount of each stud flush with the

nut. (See fig 8.) This must be done to provide clearance

for drive arm assembly (Item 80 on attached exploded

view).

Figure 5. Cutting Off Studs on Clockwise Conveyor

4. Remove front and rear covers of type "D " drive and

place on lifting device. (See fig 6.)

5. Remove drive pawl assembly (Item 83 on attached

exploded view). (See fig 6.)

Figure 6. Drive Assy Mounted on Lifting Device

6. Lift new drive part way into place. (See fig 7.)

7. Reconnect safety limit switch (Item 10 of attached

exploded view). Connect to COMMON and N.O.

terminals. If flexible conduit is not long enough. you may

need a new section of 3/8" flexible waterproof conduit.

CAUTION

BE SURE FLEXIBLE CONDUIT IS RETAINED BY BOTH

CLAMPS (ITEM 19 ON EXPLODED VIEW). THIS HOLDS

CONDUIT AWAY FROM GEAR REDUCER CRANK.

9. Attach drive arm pivot weldment (Item 7 of attached

exploded view) to front of table. Be sure Item 46 of

attached exploded view is placed under Item 7 before

attaching lockwashers and nuts. Apply liberal amount of

silicone sealant around top of hole before inserting bolts.

10. Plug unused hole with 3/8" x 16 truss head bolt. Apply

silicone sealant around hole before inserting.

11. Reinstall drive pawl assembly. (See fig 9.)

Figure 9. Reinstalling Drive Pawl Assy

Figure 7. Lifting New Drive Into Place

8. Lift drive up to the table and fasten, using 3/8"-16 and

1/4"-20 S/S truss head screws as shown. Always apply a

liberal amount of silicone sealant around the hole before

inserting the truss head bolt. (See fig 8.)

12. Check for clearance between drive arm assembly (Item 80

of exploded view) and drive arm slide (Item 53 of exploded

view). You should be able to pass a business card (0.020

shim) between the arm and slide. (See fig 10.) To adjust,

place a shim on one side or the other of the drive arm pivot

weldment. (See fig 11.) Placing a shim as shown in fig. 11

will increase the clearance. Placing a shim on the other side

will decrease the clear-ance (hack saw blade(s) work very

well as shims).

13. Make motor connections. Change motor overloads to

accomodate heavier 1/2 H.P. motor of type "D" drive.

The kit contains overloads for both old and new style

control boxes and for both 208-230V and 460-480V, 3

Phase, power connections. Old style control boxes used

2 overloads, new style use 3. Select and change the

proper overload from the chart listed below. Use the

extra overloads for other service work.

OLD STYLE CONTROL BOX

208-230 Volts Use 2 E34 Overloads

440-480 Volts Use 2 E26 Overloads

NEW STYLE CONTROL BOX

208-230 Volts Use 3 N-17 Overloads

440-480 Volts Use 3 N-11 Overloads

ADJUSTMENTS

1. Operate conveyor. When fully retracted, drive pawl

assembly (Item 83) wilt be approximately 1/2 inch in

back of roller. (See fig 12.)

The stroke of the drive is fixed at 6 inches. The

connecting rod (item 64, page 7) should be adjusted so

that the drive arm assembly (item 80, page 7) clears

both sides of the drive equally. (See fig. 13.)

2. Setting Conveyor Overload Switch.

The following test should be performed on every

Flight-A-Round dishwasher service call, even when

there is no apparent conveyor problem. Machine

damage due to improper setting of the overload safety

switch adjustment nut is not covered under warranty.

Misaligned tracks or other binds in the track wilt make

the overload switch ineffective. Be sure conveyor

flows freely around the table before setting the

switch. Usually, conveyor misalignments or binds can

be easily located. In the event that they cannot,

remove the entire conveyor from the machine. Then

manually push a 4 foot section of conveyor around

the table to locate the obstruction. Fig 14 shows the

side of the drive with the cover removed, exposing the

compression springs.

Location of Overload Compression Springs

Use a testing scale for conveyor overload safety

switch (Pan No. W-0-18410) or a 50 pound fish scale.

To hold the testing scale. Insert a 9-inch piece of 1/2

inch pipe or thinwall through the eyelet of the scale.

Test and adjust the overload safety switch setting as

follows:

(A) Press conveyor START switch.

(B) Position yourself at a curved section of the

Flight-A-Round table, preferably the curve

farthest from the conveyor drive assembly.

(C) With conveyor running, insert hook end of

the scale around the last outboard spacer of

a carrier as shown in fig 15.

nut or loosen the spring compression nuts

until the conveyor stops. (Loosen both

nuts evenly.) Turn clockwise to increase

tension.

(F) Recheck overload safety switch setting and

repeat adjustment until conveyor stops

within the 40 to 50 pound range. Lock the

adjustment nuts in position with the

lockouts. Recheck safety switch setting

after the locknuts have been tight-ened and

readjust if necessary.

FINAL ASSEMBLY

1. Install all covers and check all screws for proper

tightness.

2. Install 4-Inch section of carrier link shield over spot

vacated by type "C" drive cover. You will probably have

to customize here. Usually the carrier shields on both

sides of the drive must be removed, cut back and new

mounting holes drilled. This will provide a mounting

surface for the new shield. BE SURE TO RADIUS ALL

SHARP CORNERS. (See fig 16.)

3. If machine is equipped with one man cost control, it will

probably be necessary to reset the cost control timer.

Refer to Section 13-37 of your Service Manual for

Modular Dishwashers for complete recalibration

instructions.

(D) Pull back on scale, noting scale reading.

Conveyor must stop when scale reading is

between 40 and 50 pounds with conveyor

(E) If conveyor does not stop, turn off the conveyor

and adjust tension of overload arm extension

springs. Loosen the lock-
