Japa 370 sprocket supplier & Powershap bar

[AndyChalmers]

I have a Japa 300 & 370, I am considdering fitting a Oregon Powersharp bar setup. This way it should make sharpening easier, consistant and less downtime. Both machines are running .325 chains however the powersharp only do 3/8 chains so would need to change the sproket to 3/8. Japa do the 3/8 sprocket hower seem very expensive at £42.40 + P&P + vat. Can anyone else reccomend a supplier, its using a 1:8 european taper & 9 teeth.

 

Also does anyone have experience on the powersharp on a processor?

 

Thanks in advance.

Wouldn't bother with the Powersharp - real waste of time and money. Even our local dealer has been left with old stock and couldn't return it to Oregon after customers gave up on them. It seemed like a good idea but in practice it wasn't.

I found the bar constantly binding up, slowing down during the cuts- changed back to original on Echo 350TES and flew through the job twice as quick.

Chains went straight in the scrap bin, but the bar was ok with normal chains until it wore out about a year later.
