Chainsaw Sprocket

[sawman39]

Hope someone can give me some advice on this.

 

I recently bought a Oregon chain for a saw, this is the one I bought: [ame=https://www.amazon.co.uk/gp/product/B00665KPX0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1]Oregon 73LPX068E Chain, 3/8-inch Pitch, 68 Drive Links: Amazon.co.uk: DIY & Tools[/ame]

 

 

The chain fits the bar fine as that is the type of chain stamped on the bar, this is the one I have: [ame=https://www.amazon.co.uk/dp/B0029ZQDZ0/ref=pe_385721_51767431_TE_dp_2]Makita 415045655 45 cm/18-Inch Sprocket Nose Bar - Multi-Colour: Amazon.co.uk: DIY & Tools[/ame]

 

However I don't think the sprocket on the saw is correct for the chain, its a 325-7T similar to this: OREGON PRO CHAINSAW SPROCKET DRIVE RIM 11892 .325 7 TOOTH | eBay

 

I'm not even sure what i'm looking for even exists however the chain seems to grind on the sprocket a lot. Can anyone tell me if there is a different type of sprocket available to suit this setup?

 

Thanks in advance....

You need a 3/8 7 tooth sprocket or a different rim drive. What saw do you have as a 3/8 chain is for the bigger cc saws 50cc plus

It originally had the smaller depth bar with what i would call a standard 18" much lighter chain....

You are running a 5/16 pitch sprocket with a 3/8 pitch chain,so change one or the other. You might have a problem finding a sprocket to suit that saw however.
