3. Loosen cap screw and lock nut that secure idler
sprocket (item 5) to frame. Move idler sprocket to re-
move tension from drive chain.
4. Locate and remove master link (item 16) from drive
chain. Note direction of master link clip for assembly pur-
poses. Remove drive chain.

2. Position square key to slot in drive roller shaft and
then slide sprocket (item 3) onto shaft.
3. Fit drive chain onto floor motor sprocket, drive roller
sprocket and idler sprocket. Install master link (item 16)
to drive chain and secure ends with master link clip.
Make sure that the closed end of the master link clip is
facing the direction of chain rotation.
NOTE: Direction of normal roller rotation is shown in
Figure 5 as viewed from right side of conveyor.
4. Check that chain is aligned to sprockets. If alignment
adjustment is necessary, move sprocket on drive roller
shaft as needed.
