Pioneer chainsaws

[TBone0106]

Sure do. They're visible in the older post now as well. Go figure.

Cool saw.

Thank the Good Lord! I was beginning to be a bit cluster-flustered! :msp_thumbsup:

I like the saw. If you scroll back a page or two, I posted about how I got it, one of the luckiest deals I ever scored on Craigslist. I've just never been a fan of the newer saws with their anti-vibration suspensions and choke-me-to-death mufflers and mousetrap chain brakes. To me, they're like squirming things, trying always to wriggle out of your hands, and ready to bail on you at a moment's notice.

This 3071 is tuned so it's running from a cold start in five pulls or less, and that .058 chain throws Fritos that look like something you'd buy at the pet store to bed your Guinea pig in. It's quieter than my older blue-and-white XL-12, and more powerful and dependable, largely thanks to the electronic ignition and the automatic oiler.

Anyway, thanks for your help with the pics.

It's always great when you get a saw your really happy with.

Speaking of which -- and I'm not trying to hijack the Pioneer sticky -- I think that this year my "dynamic duo" will be the 3071 for felling and rough work, and one of the sweetest li'l saws I've ever put hands on for branching and trimming -- a 1970s vintage Echo CS-315 early model, the one with the single bar stud. It looks like this.....

Yeah, it's Japanese-made, but DAMN! It is one of the finest small saws I've ever held in my hand. Starts on three pulls cold, runs like a scalded dog, and absolutely OWNS that li'l 14" bar and chain.

I like to carve my trees from the bottom up. I figure when the trunk and/or branches get down to 12" or so, Li'l Red will come up to bat. Until then, just stand back while Mr. 3071 tears the place up. :msp_biggrin:

new to me Farmsaw and new to saws in general

Hi Guys.
First time on this sticky thread. I picked up a Farmsaw sunday ($40), nice chisel chain, bar looks OK. Did a compression check but it seemed low to me...90psi. Do these have an auto compression release-yes? Filled it with mix and bar oil. Well it still fires up OK... and it ripped through a big piece of red oak just fine. since at 66cc it is now my biggest running saw.
My question for the Pioneer knowledgeable is. after the cut, I flipped the saw on it's side to try and determine the conditon of the crank seals and it did die.... repeat.... died again. I'm wondering if these are known to have weak crank seals or might it be gas puddleing up in the reedvalve box or crankcase that gets upset when it gets flipped on it's side? Added... it does seem to have a rather long time to idle down until the chain stops moving.....?vacuum leak?
thanks

I'll answer what I can, they do have an automatic compression release (the starter actuates it). The starter rope spool is the weakest point (plastic), and it's almost impossible to find a replacement. Exercise care. I suggest you not disable the compression release to test compression. Maybe if done with a ratchet, mine is a right hand thread.

It does have an auto compression release. Don't try to check the compression by disconnecting that or you may break some very hard to find starter parts

Both are typical signs that the saw has a vacuum leak. If you can vacuum test the saw you should. The seals are not known to be failure prone but the saw is from 1982 so the seals should be replaced.
The seal PN is 428746 for both sides which are not too available. You can still get the Poulan / Pioneer (405, 455, 525, 655) saw seals which are the same under Poulan PN 507428746 for less than $4.00 ea.
All of my reed valve saws have no issue running in any orientation.

I forgot to add that the oil pump worm gear is a press fit on the crankshaft. Measure carefully for location so you can put it back where it was after changing the seals.
I will PM you a link to a service manual you can download. You can find an IPL for the saw at Chainsawr (one of our site sponsers)

Poulan purchased Pioneer long ago.
At that time they prefaced the Pioneer part number with 507. Many Pioneer parts are still available; if you preface the Pioneer part number with 507.

Thanks Tim & Lou
The links and info are well appreciated. Hopefully it will give me a chance to fix this saw up rather than kill it from an air leak.

farmsaw starter parts

Hi Guys
Quick follow up please.
What starter components are particularly tender and breakable?
The actual starter cover or
507430609 starter pulley $6.00?
507429892 starter pinion $2.90?


found Crank seals too 507428746 $3.03?
??? if actually available

thanks
Dave

I just bought those seals a short time ago for my P51. They are still available from Poulan Pro.

I can't say for sure which parts in the starter break but someone will be along who does. An old repair guy told me that the wire 432129 also breaks.

507430609 starter pulley $6.00 on mine. I broke it; the starter rope hung in brush while the saw was running (for very short time). The 507429892 starter pinion $2.90 ate the ends off the spirals. Looking at the parts, I think the pulley the weakest link.
One other part that has failed once or twice is 432129. It used to be you could get a 507432129 replacement, but that is no longer an option. If you have one that's intact to use as a pattern, I think some piano wire could be easily formed to create a spare. The only critical size IMO is the part that wraps around the starter pinion. I think the correct sized socket (need to experiment) would work well. If you make one please let me know what size socket you used.

Clarification:
The 507429892 starter pinion ate the ends off the 507430609 starter pulley spiral flutes. The starter pinion itself appears on harmed.

Stupid! If I edit I get nicked, if I add a post I get rewarded. Plugging up the thread with crap is better?

One of my favourite saws, my P51

24" bar, semi chisel chain (DPX I think)

Nice saw and a very nice pile of saw dust. One of the best saws Pioneer made.

The first unposted vid was more exciting when it chucked a cookie at high speed at the patio sliding door window. Scared the wife.
Today I'm thankful for tempered glass.

Does the 2073 and P 26/28 use the same chain adjuster? TIA
