Replacing the drive sprocket

and drive shaft

WARNING!

Lock out power before proceeding!

NOTE: Before replacing the drive

sprocket and drive shaft, you must

ﬁrst perform the following steps.

1. Remove the top and inside

covers from the drive

module (See Fig. 13 on

Page 16).

2. Remove the drive chain

(See Fig. 24 on Page 23).

3. Disconnect the transport

chain. Refer to page 28 for

the correct chain break

procedure.

4. Remove the transport chain

from the drive sprocket FTC

by pulling it back over the

idler sprockets.

NOTE: For this step you don’t need

to remove the chain completely from

the line. Back the chain just enough

so that the end of the chain clears the

area to be work on.

5. On the sprocket drive FTC

loosen the set screws using

a standard hex wrench.

6. Next move the C-clips

toward the center of the

shaft so that you are able

to slide the sprockets freely

back and forth along the

shaft.

7. Remove the woodruff key

and slide the sprocket to

toward the center of the

shaft.

8. Loosen the set screws

on the collars on ﬂange

bearings using metric hex

wrench.

9. Push shaft towards the

drive sprocket and remove

the ﬁrst sprocket.

10. Next remove the C-clips

from the shaft to remove

the second sprocket.

11. To replace the shaft, push

the shaft from the unit until

so it is fully disengaged

from the module.

IMPORTANT!

Before replacing the shaft, apply

anti-seize grease to the shaft at the

sprockets and ﬂange bearing. Use of

an anti-seize lubricant is imperative.

Failure to use anti-seize may cause

the sprockets and shaft to seize up,

subsequently making them difﬁcult

to remove.

NOTE: Apply anti-seize lubricant to

the hex shaft at all contact points.

NOTE: Apply removable thread locker

such as LOCTITE® to the set screws

when replacing the sprockets.

12. Reinstall the shaft and

sprockets by reversing steps

1-11.

It is also necessary to

measure the spacing

between the drive side

plate and the new sprockets

to make sure that it is the

same on both sides. A visual

check is not sufﬁcient, since

uneven spacing may cause

the chain to bind up and

result in severe damage to

the equipment.

WARNING!

Do not operate the system with any

of the covers removed! Serious per-

sonal injury or damage to the system

may result.
