3.3 Flat Top & Friction Top Installation
3.3.1 Identify chain and sprockets

Chain identification can be found on the underside of the link/top plate. Sprocket
identification can be found on the face of the sprocket. Detailed information on
each sprocket and chain can also be found in the product catalog.

Check sprocket and wear strip position

Ensure that sprockets, carry and return wear strips are properly positioned.
3.3.2 Sprockets and wear strip position

The distance from the end of the wear strip to the sprocket shaft centerline
should equal 1.50, otherwise the wear strip will interfere with the free articulation
of the chain as it enters the sprocket.

The leading edges of the wear strips should be beveled.
3.3.3 Align drive and idler sprockets

Make sure that the drive and idler sprockets are aligned axially with the center of
the chain. Lock the sprockets in place using the keyway and setscrews.

If multiple strands share a tail shaft, key only one sprocket and allow others to
rotate. Collars should be utilized to prevent axial floating.
3.3.4 Idler Wheel and Sprocket Locations

The idler wheels can only be used in place of tail shaft sprockets on Rex®
TableTop® one piece unit link chains.

Idler wheels should not be used with roller base chains

For proper location and smooth operation, the idler wheels should be mounted
below the top of the wear strips.
3.3.5 Inspect guide clearance in both straight and corner sections

Check the carry and return wear strips at several locations to ensure proper
guide clearance. Check the corner tracks and discs for proper thickness. Make
sure there is adequate clearance for chain TABs. Ensure straight and curved
sections are lined up properly with smooth transitions. Adjust all items as
required.
