Japa 370 processor premature bar wear

[gensetsteve]

As far as I can tell it’s not the chain going blunt quickly seems to be the bar wearing before the chain gets a chance to dull. The bar gets a good shot of lube on 6 inch stuff not so sure if you put lots of 12 inch stuff through

I sorted all my problems in the end by fitting a Sugihara Bar, all my problems disapeared.  Bars been on a year or so now and still fine.

Thanks for letting me know . I have checked our machine everything looks spot on unworn and in-line . I am thinking it could be poor quality bars . Might order one up and give it a go

I think Sugi bars are made from Kriptonite whilst others are made by Cadburys .

I have a Japa 370 processor.  I fitted a new chain & oregon pro-light 158SLGK095 bar not long ago.  Cut about 20 m3, never sharpened chain and bar had worn badly, chain slops about and not cut straight.  Turned bar over and perfect agian.  sharpened chain & done another 15-20m3 and bars worn again.  it doesnt seem to be cutting perfectly straight so measure the angle and only out a degree or so.  I canrt see how to get it true again.  Ive never had a problem in the past tho.  Its lubing correctly just wearing the bar groove out so chain does not sit square.  if i cut on the tip its perfect.  Can anyone reccomend anything or recomend a harder wearing bar?    

My mate has just had the same on hilkie pikie. And turned out to be the drive sprocket worn
