Most of that series came with .050 or .058 ga chain. Which isn't much help. I think that saw may have a .325 pitch chain on it but I can't find the specs for a P25.
Do you have a Vernier caliper you can check the slot width with?

There's always this test. Make sure the coins are in good shape as the rim on the edge of the coin is the measuring point.
- Penny = .058 gauge
- Dime = .050 gauge
- Quarter = .063 gauge
Cool trick
Thanks for the tip! That’s a great suggestion. Checking the dimensions of both Canadian dimes and pennies I found the following thicknesses: 1.22 mm and 1.45 mm with .050 gauge being about 1.27 mm and .058 gauge being about 1.47 mm.
Nonetheless I would still appreciate if someone could tell me the actual dimensions given that my saw is up north and I was hoping to purchase the chain before I traveled up north next week.
At this point I am wondering if perhaps Oregon lists both gauges as both would be acceptable for the original bar?
regular feeler gauges will tell you the gauge /gap in the bar, if you have chains that you know around try them on the sprocket and see if they seat right.
All three of the gauges are available in .325 and 3/8 pitch. If your saw has been used a lot the rails and groove may be worn considerable past where it should be. Typically a chain that is loose in the bar may cut crooked as it will rock back and forth. Even if it does cut straight, my very limited experience tells me it won't cut as well as a chain the fits the bar properly, Maybe some of the guys who cut a lot could chime in on that point.
Asfar as the chain tension screw, I can't be sure as I have a 1074 and another of that series which is a wreck. The 1074 I have uses a 10-24 bolt, 1-3/4" long,
If you don't have the pin / pawl that slips into the bar, You'll have to look for that on line or make one if you're handy

LMAO Stop it ...
For the chain tensioner I am wondering if something like the following would work: https://www.ebay.com/itm/Bar-Adjust...A-136-137-141-142-Chainsaw-Chain/262773044483 or this https://www.ebay.com/itm/Chainsaw-C...varna-141-142-136-137-530016110-/352304689545 ?
Even if the bolt is not the right size perhaps the pin would be ok?
Maybe you could try that Husky dealer saw shop on Weston Rd to see if he has stock if you're in a rush for it. One for a small Poulan one would be the same.
That would likely work but you may need to file / reshape the pin to work. You might have to cut the bolt as well.
It should be easy to do with basic hand tools.
You could pick one up at a Poulan parts place or a Husky shop. Not sure where you are in TO but there's a Husky shop on Weston Rd, Chain saw clinic. Not cheap but if your in a hurry for it.....

I'm glad to hear you think it may work. I do have a bench grinder and so could easily reshape the pin if that is required.
Even though I don’t live that close to the Chain Saw Clinic I pass by it from time to time as I occasionally shop at the Superstore across the street as it is on my way up north. Oddly I have never had occasion to use it as the Pioneer has been old reliable never requiring any type of service since it was bought over 40 years ago. My Stihl is another matter and for that I use a Stihl dealer close to me in Toronto or up north.
Speaking of which I did speak to my Stihl dealer up north and he was pretty sure he could have his mechanic build me a custom chain that would work for my Pioneer for about 30 bucks. I never asked him about the tensioner. Again he is pretty busy and he couldn’t give me a firm date as to when it could be done or guarantee that he had the right chain for me in the first place.
Looks like I have some calling to do tomorrow.
I only takes 5 - 10 minutes to spin a chain up. I don't know if the Stihl dealer would have a chain tensioner for your saw. Stihl uses a different type.
Stihl chains are very good chains.
Stihl chains are very good chains.
How would you compare them to Oregon?
That's a loaded question as it boils down to personal preference and cost. Oregon and Carlton cutters are a little softer so easier to sharpen and easier on the files. Stihl is harder on files but stays sharper a little longer.
I think Stihl is preferred by most frequent users but is often quite a bit more expensive depending upon where you live. If the guy is offering a Stihl chain for $30 I would go with that over Oregon.
I don't think one is faster than the other as far as I can tell.
If someone was throwing free chains at me I would like them to be Stihl. For the infrequent cutting I do, I like semi chisel chains as I cut some dirty wood and it says sharper longer.
I believe the Stihl semi chisel chain is Rapid Micro.
Looks like I am going to need to buy some extra files as getting an Oregon chain is a moot point since no one can tell me what gauge I need. I will have to wait until I get up north and take it to the Stihl dealer and see if he can fix me up. I’ll ask him what gauge I have. Hopefully I won’t have to wait too long. I was looking at getting some Oregon chain from Amazon for about $20 including shipping but that does not appear to be an option for me at this point in time.
As for the chain tensioner, I went ahead and ordered one from eBay for a grand total of US $1.28 including shipping!! Hopefully at the very least I will be able to use it as a spare.

I just buy the cheap longer loops (Stihl , Oregon ,Carlton , ect ) off internet and spin them whatever size needed. Cheap Harbor freight spinner has worked great . Pin press is not that good but if you notice it you can deal with it . I also found new jaws for this vice !
The Canadian made P26 came with .325 pitch .058 gauge chain from the factory. Same for the 1074 and P28.
Hi Jerry!
I couldn't find any info on the P25 except for Acre's site. It says it came with a .325 as well but no way for me to be sure.
Do you have any info about the gauge of the chain from the factory for the P25?
Hi Tim!
My books and charts say the P25 came with a bar#474254 in 3/8 pitch with Duraguard chain in .058 gauge, it also states other bars and chain could be substituted. Hope this is some help but nothing carved in stone as bars and chain often got swapped over the years since leaving the factory.
by the dealer if the purchaser wished a different size.
