The bar on my Husq 394 was changed about 8 years ago. So it's well worn. The gauge size printed on the bar tells me it's .058". I've been buying my chains for this saw from Patrick, a parts supplier for 10+ years. Then Patrick introduced his son Paddy to the shop and went off to see the world. Last week I needed a new chain for Husq 394 so I took my old chain to the shop, threw it on the counter and said to the wee fella "give us wan of those lad". He came back 15 mins later with a box containing a chain. I took it home, without checking it, put it on the 394 and went to clear a site the next day. Less than half way through logging a medium sized spruce the nose sprocket disintegrated and the groove on the nose spread like a spread thing. I immediately phoned the parts shop and got talking to Patrick's sister Patricia. "Can I order a new bar for a Husqvarna 394 cutty"? I asked. "Call for it the mara" she replied. I did. I took the bar home and tried to put it on the saw. The gauge was too heavy for the bar, not the nose funny enough, but too thick for the bar! How the **** did it fit on the old bar? It must have been worn enough for it to fit perhaps? The old bar had .058" stamped on it. The new bar had .058 stamped on it! What was going on? I haven't measured it yet with a caliper, because I don't own one, but I'm thinking Paddy sold me a Stihl .063" chain for the Husqvarna.058" bar.
Here's my question; Could the .063" chain have fitted onto a well worn .058" bar and then caused the sprocket nose to fail? If so should wee Paddy be responsible and pay me the €120 I paid Patricia for the new bar? Or should I say nowt, just be more careful and pay more heed to what chain I'm putting on my bar?
The other side of the coin is; perhaps the old bar was ready to crash anyway?
