Mr. Mark’s Maintenance TipsChain Failure is PredictableWhen measuring 10 links of 6” pitch:Agosto 2005 ”Conveyor Systems That Deliver!”35
Mr. Mark’s Maintenance TipsDo Not Grind Chain Pins The shoulder is in good condition on this pin. It is needed sothat the pin can be pressed into the side bar. The shoulder on this pin has been grinded down.This may allow easier installation but will cause theChain link to wear down at an accelerated rate.When the pin shoulder has been grindeddown it allows movement inside the pinholeon the link, which wears down the inside ofthat pinhole.Agosto 2005 ”Conveyor Systems That Deliver!”36
Mr. Mark’s Maintenance TipsSprocket ReplacementExcellentTime to ReplacePast ReplacementPossibly wearing down chainWhen Sprocket is worn or hooked from 3/16” to 1/4”, it is very important to avoidirreversible harm to the barrel of the chain. As Tramco sprockets are symmetricallymade, after you wear off one side of the tooth, you can turn it over and wear the other side.Agosto 2005 ”Conveyor Systems That Deliver!”37
Mr. Mark’s Maintenance TipsSquaring the Steel Shaft In order to get the maximum life fromyour tail bearings it is extremely importantthat the tail shaft is adjusted in its finalposition completely square with the flangeon the intermediate box. When the bearing is under misalignmentearly failure is possible. That is why it isvery important to square the steel shaftwhen adjusting proper chain tension.Agosto 2005 ”Conveyor Systems That Deliver!”38
