oregon chain

[64treefrog]

I have two old boxes with Oregon chain loops in.

The chains are micro chisel, 72 links but they have 23 on the drive links!

what pitch is this? I believe its 3/8ths but cant find 23 on oregons site

may be a stupid question....

 

thanks

Chain pitch is the distance between the centres of three consecutive rivets, divided by two.

 

Hope this helps.

Old boxes you say. If they were Stihl chains, the 23 could denote pitch & gauge.

2 = .325" pitch

3 = .050" 1.3mm gauge

 

Just because they're in Oregon boxes, doesn't necessarily mean they're Oregon chains.

Cant you just compare it with another chain?

Easy to compare pitch, not so easy to compare guage.

 

Huskie have a 23 chain but its a full chisel.

 

The makers name is often stamped on the ties, but you may need your glasses!

If you have the chain and bar to hand the Mk1 eyeball will suffice, if it fits good, if it fits and wags about a lot bad.

True, if you have the bar.

 

But the inexperienced can easily end up putting a too narrow a guage chain on, then wonder why they cut a curve.

thanks guys

 

they are Oregon (sorry didn't say) 3/8ths 72 link and probably were meant for 056 stihl.

My question was;

did anyone know what the 23 refered to as other Oregon chains have 25 on the drive link.

I thought it would be a simple case of looking on the Oregon site but they don't mention 23.

someone out there will advise me!

The 25 on the rakers means that the (initial) raker setting is recommended to be 25/1000 of an inch - but that has nothing to do with the drive links (or the model number of the chain). There usually is a different number down on the tangs that go down into the bar slots and sprockets, and it is that number that is needed to ID the chain model.

Husqvarna chains are made by Oregon and there is a Husqvarna 23.

H23 is .325", .050" 1.3mm full chisel.

H25AP is .325" .058" 1.5mm and quoted as a 'Micro Chisel'.

 

Have a gander through here:

I think you may well find your answer in there.
