chains

GERMAN ROCKS

How would you tell if a chain is worn or is in good condition by looking at it? ALso how tight is too tight with a chain? Is it better to have them a bit tight or a bit loose?

no on a baler

When a chain wears, the pitch on the chain increases. You can get chain wear gauges for bicycle chains.

Chain stretch and wear (on a Baler)
Chain wear is a normal condition and needs to be checked regularly to ensure proper length is maintained. Over time, the movement of the chain over the sprockets will cause the pins and rollers to wear and become elongated or oval-shaped. When this happens, the pitch of the chain will change because of the increased length.
At only 3 percent length extension, the chain should be replaced to avoid the dreadful clanking of a sudden failure. You can purchase a chain wear gauge that will assist with this task. Regular lubrication will help to extend chain life.

I prefer them a bit loose on the baler, just have a little bit of slack on the longest straight run of the chain. Plenty of oil is the secret to long chain life though
