Show/hide table

The harvester head frame may tip over when it is in the vertical position. Personal injury or death may result if this occurs. Secure the frame to the yoke with a chain or similar restraint prior to working on the harvester head.

Note: Chains should be replaced one at a time in order to maintain the proper orientation of the chains to the feed rollers.

1. Ensure that the harvester head frame is in the VERTICAL position. Fully open the feed roller arms. Secure the frame of the harvester head to the yoke with a suitable chain. Refer to Disassembly and Assembly, "Preparation for Disassembly" for detailed instructions.

2. If the chain is not broken, cut the chain. Remove the pieces of the chain from feed roller (4). The chain is held onto feed roller (4) by having a link of the chain placed into a slot on the front and back of feed roller (4) .

   Note: When the first chain is broken, this chain should be replaced. The chains usually break at the end of the feed roller that faces the harvester head. When you replace a chain, change the direction of all other chains. The end of the chain that was facing the harvester head should now face away from the head.

1. Use Tool (A) to replace the chains.

2. Cut a piece of 161-8209 Chain to the appropriate length.

3. Insert one end of the feed roller chain into the groove on the rear side of the feed roller.

4. Wrap the chain around the feed roller. Keep the chain in the channel of the rubber tire on the feed roller.
