Breaking in a New Chain Saw Chain

[djauto]

Dexron II or III?

Don't act stupid on this one, you know only to use Mercon on the pre 78 chains and Dexron III works on all 79 and later chains. Dexron II can be used though on 79 to 94 chains if Dexron III is not available.

oke:























If you are new to the site, just run the stinkin' chain with oil in the saw and don't worry about it. If you feel the desire to soak it, then by all means soak it. I don't.

This sounds a bit like OCD to me.

Dexron II or III?

tsk tsk.

Dex II and III don't officially exist anymore so you have to use Dex VI which is backwards compatible. :greenchainsaw:

Now wait a second, dont confuse every one, do you mean Dex IV, Dex V, Or Dex VI?

And runnning Dex II, III or any others when specs call for Mercon can be a bad idea.

+1 Never heard of anyone (or manufacturer) recommend any breakin procedure for saw chains. Use'm till they need sharpening, then sharpen them.

See page 34 of this Oregon manual...pretty close to the OP's method...

Holy shmackerolly...What a load of extra work!

Put the new chain on, tighten it a bit more than normal, start it up, run it no load for about 30 seconds, make sure its throwing oil, retighten and...

GO TO WORK

And that should be the end...

I wonder if any of the guys here have ever used a torque wrench on their
bar nuts?

Pretend like I have...

 

[skid row]

Over the years my nuts have been torqued a few times.

 

[stihl sawing]

24lbs per nut.

:jawdrop:
Thats some big nuts

LOL, Yes they would be. I have no idea how much torque you need. I just tighten them till i think they are right.

 

[Darkness77]

Does anyone used the supplied screwdriver socket thingo to tighten thier bar nuts? I use a socket, It seems much tighter on the nut.

I use a ratchet and socket too.

I use a ratchet and socket too.

After years of over tightening the nuts on the Dolmar with a 1/2" drive ratchet the studs broke. On inspection they seemed to be stretched. I now use a Stalwhille flexi socket wrench. Its a lot shorter than the ratchet and is a nice tool to use as well.

Yup, Know what ya mean.you can tighten one up too much. I also use a shorty ratchet.

I always treat my new chains in a bucket of liquid nitrogen. The affect is transformation from austenite to martensite which increases their strength and hardness. Just do a search under "cryogenic hardening".

Once you do it just throw away the silly files and jigs and chains will stay sharp for years and years.

I wonder how a pair of 24 lbs nuts would perform after they were "cryogenically hardend"?

 

[Darkness77]

My guess is they would explode upon touching anything worth hitting.
