Pioneer chainsaws

[Howsitgoineh]

Many of the small cc Pioneer saws came equipped with 3/8" chains, the powerheads were reed valve induction and had more torque than piston ported saws make, they could pull the bigger cutters really well.

This is something I was unaware of, all my small frame pioneers run a .325 - they are some of my favourite saws. Plenty of torque, I use an 18" bar on most but have a few 14s and 16s.

I may look at putting a 3/8 drive on a couple of them in the near future now that I know this

Basic question gents:

This 1200A I have recently attained leaks fuel from the fuel cap. Based on the IPL it seems I am missing a gasket under the fuel cap.

I'll just make my own....can anyone advise approx gasket thickness I would need. Probably doesn't really matter, but just thought i'd ask before buying a cork sheet

Duckbill valve. I made one for an old poulan out of a flexible bottle cap off a seafoam container.
They are pretty thin silicone usually, can't say specifically what thickness but it is pliable

Hope this helps some

I'm referring to this gasket in yellow..once again I could make it out of any thickness I guess but I thought I'd ask.

Ah, gotcha. Even a plumbing o-ring would work there
Are you using gasket material, or something like form-a-gasket?
Silicone would work too it's flat like a hose gasket.
No particular reason I am asking, just out of honest curiosity

 

[Little Jerrry]

Hadn't thought too hard about it....I was going to either just cut out a cork gasket or grab an o-ring.

I'm just happy that this saw runs well enough as this is my first old Pioneer saw and parts are few and far between (especially in Australia).

The .325 chain cuts better on high RPM saws whereas the 3/8 cuts fine on older lower RPM saws back a bit further in time most saws ran larger chain types.

P21:Is the wrist pin bearing replaceable? If yes Does anyone know of a procurement source.

I've found the Pioneer/IEL saws to have standard Torrington bearings in the rods. You'll have to disassemble to read the number.

My Pioneer Farm Saw has an O-ring fuel cap seal. I wouldn't be surprised if the majority of Pioneer saws used an O-ring.

Hey Lou, some came with flat gaskets while others had O rings, was model by model specific. The 1200A would have had a flat gasket, pioneer part number 427273.

CB took your advice and the number is y67.checked the torrington catalogue and that # isn't listed.any other options?

 

[cbfarmall]

That doesn't sound like any torrington number. Should begin with a B or J. Got a picture. The other option is to measure bearing. Pin diameter, OD and width.

I have been known to take clear pictures of the bearing numbers with my cell phone camera and zoom in that way to read the numbers.

Wrist pin bearings were commonly Torrington but your best bet is to remove the bearing you have and check to see if there is a makers name on the end of the cage.

Shouldn't have to remove the bearing from the rod to read it but you will probably need to clean it well. Every Pioneer I've take apart had a Torrington in it. Granted, most are older than this P21.

Looks like that saw shares the bearing with most of the small Pioneers 427662.

Picked up this P50 and a 650 today. P50 looks rough but has a super clean piston and cylinder and makes about 125psi and so far I haven't found any broken bits but no spark (will dig into that) and the 650 looks decent but was a package deal so I'm not sure what to do with it.

185cc's of awesome

The 650. Very clean
