coal bin auger questions

PostBy: e.alleg On: Wed Aug 01, 2007 12:16 pm

I set up the auger today on my EFM 520 and I noticed there is no bearing on the bin end of the auger. This causes the auger to lay inside the pipe (when there is no coal in the pipe) and seemingly will cause the auger or the pipe to wear out over time. Does the end of the auger need to be supported or am I wasting my time? It might sound like a stupid question but I'm used to working on motorcycles where just about everything is measured to .001" tolerances.

Ours has been like that for 25 years and hasn't worn out yet and doesn't show any signs of doing so. My Grandmother's is even older and the steel pipe on hers wore out on the end but I'd imagine that was also due to corrosion in addition to friction and I don't think hers is quite as heavy gauge. The worm is the only really expensive thing to replace, ours are stainless and I'd imagine most are so the wear is minimal.

Like graphite the coal itself acts like a lubricant too.
