New Chain Problems on Husky 240

[derwen]

Hi, looking for some advice. I have a Husky 240 for light work which has a 14" bar and have just bought an 18" bar and chain to suit from local dealer. The bar is an Oregon and rge chain is a Husky 21. Tried fitting the chain and bar today and all look OK until tried turning the chain after tensioning. The chain moves for a couple of links and then wont budge forwatd or back. If I slacken the tension the chain dropps off the bar. Tried tensioning again and same thig happens. When I turn the saw over to look at the sprocket it looks if the cahin is trying to run from inside of sprocket to out side of sprocket - thought maybe a bent link, but when I lay the chain flat it looks OK. Any ideas, although I'm going back to the delear to see if they can sort, but if there is soemthing obvious that more experienced people on here know could save me a "RED FACE". Fair to say I have only used Stihls in the past so I may be not doing something right. Many thanks

I'd hazard a guess that one is small 3/8ths and the other is .325

 

have a look on the bars and see if you can see anything stamped into then, usually near the saw end.

the 240 runs 91vxl chain 3/8 .050 you are trying to run .325 chain on a 3/8 sprocket, the 18" bar will cause the saw to struggle, it is ok with a 14" or 16". thats why the chain will not mesh with the sprocket.

Yes the small bar is 3/8th and the new bar is .325. The new chain has Husqvarna stamped on it and 21. The new bar is an Oregon, the new chain came in an Oregon box with 21 LPX written on it. Can't find any info on Husqvarna chains. Does anyone know if an Oregon 21 LPX is the same as a Husqvarna 21. Thanks

I asked the delear if I needed to cahnge the sprocket to match the new chain and bar as one was 3/8yh and the other is .325 but he said no. Need to go back and speak to them again.. Thanks for help,

I wouldn't have too much faith in the dealer in that case!

Try contacting Rob D, he's one of the site sponsors on here and runs www.chainsawbars.co.uk

He'll sort you out with the right gear.

You will find an Oregon Micro Lite Pro and 95VPX will run nicely on your saw. Your local dealer sounds like he doesn't know much about saws if he reckons 0.325 bar and chain will run on a 3/8 sprocket of vice versa!

Problems aside, the 18" might be too much for that saw anyway. As you say its a great 'light work' saw on a 14", i love mine. Any heavier work and i'd be reaching for a more powerfull saw.

All the above seconded.

i had a 240 and im sure it was running .325 pixel chain (15inch) and i can remember it cutting well
