5.4.1. Belted Chains
1. Belted chains are vital to the safe and efficient
operation of the harvester. To prevent unsched-
uled downtime, Inspect and maintain the listed
belted chains as specified. See the parts manual
for the correct replacement parts.
2. Perform a daily visual inspection on all belted
chains. Repair or replace as necessary.
 Inspect the Web Joiners for wear. Due to the
metal on metal connection in the Web Join-
ers, they tend to wear more quickly than the
rest of the belted chain. It is not uncommon to
wear out multiple Web Joiners during the life
of a belted chain.
 Inspect the webbing for cracks and tears.
 Check for detached, broken, or missing rods.
 Check for bent rods. Use the provided Belted
Chain Rod Straightener to straighten any bent
rods. (See Figure 9)
 Check for loose or missing rivets. Drill out and
replace as necessary.

 The webbing for a Belted Chain has a pattern
of notches and cams. Each notch carries a
chain rod. The distance between the notches
defines the pitch of the chain. (See Figure 10)
 The Web Joiner conforms to the same pattern
of notches and cams which is present on the
webbing. The Web Joiner is designed to fit
over one end of a Belted Chain web and to
connect to the mating side of the Web Joiner
