1st post and some guide bar help needed ... :)

Aha! ... I think it maybe A318 I'm looking for:

 

Bar Mount Pattern: 08

I bought one of those "intenz" bars once - it was cr*p and I threw it away long before it was worn.

But I wonder if you could just drill holes in one and use the normal screw tensioner

[eldon]

If you find you can't get the bolts tight enough ensure you are getting adequate chain oil flow as something maybe blocked or faulty.

I once got a saw given and keeping tension was impossible until the penny dropped that the oil level wasn't going down fast enough as the pipe was nipped. This of course needed an entire strip down to resolve but went on to be a good saw for quite a while.

I did a partial strip down, clean up and rebuild as the saw had been lying for what may have been years .... I've got a good workshop here and the head seems to run fine now.

 

The chain was getting plenty of oil ... the problem was it hadn't been sharpened at all for a long time by the looks of it and had been used for cutting up pallets, the teeth were rounded and polished, you could have almost run it on the palm of your hand and just got tickled ...

 

The old bar was very badly burned and worn, not enough slot depth left in a couple of places to fix it.

 

I ended up ordering a new Oregon 18" 180SDEA318 standard bar and a 91VXL chain for it for £35 delivered ....

 

Parts place wanted £15 for the genuine tensioner screw and pawl ..... :lol: :lol: :lol: so I'm just going to fabricate one for about 50p ...

 

The Intenz system makes it really easy to get correct chain tension but I found that it slackened off really quickly too making you want to crank the nuts tighter and tighter all the time.

I hope you get on well with it.

However, there is no way the bar is going to make any difference to your chain tension issues.

The bar nuts hold the tension, not the tensioner so whatever means of tensioning you use the result will be the same.

I'm taking it you've not used an Intenz bar ...

 

In my experience the standard bar tensioning system does contribute a bit towards keeping the chain from coming loose when compared to an Intenz .... certainly the one I'll be making will.

 

Or are you saying that it is the A318 mounting design that is fundamentally flawed or maybe I just need a breaker bar on the wrench to get some more torque ....

[Daniël Bos]

I have actually, but admittedly just for a play at the saw-shop.

 

All I was trying to point out that regardless of the tensioner, the bar nuts should hold the bar.

 

It may point to another issue if they don't.

 

I wasn't suggesting you're limp-wristed or some such, just that there may be another cause than the tensioner.

[Check12]

In the end I wasn't going to waste anymore time on it ... the bar is knackered ... from reading a bit more apparently your supposed to be able to feel the intenz adjuster click when you adjust ... this one certainly doesn't.

 

I am used to using the standard screw tensioner design and the price of a traditional bar is half the price of the intenz ...

 

There are no parts missing from the saw and no other issues ... I'm sure when the new bar and chain arrive it will be fine ...
