Pioneer chainsaws

Would it be possible to turn that into a spline sprocket?
Then if I understand correctly any chain could be used given the correct rim.

Lou ,
That is my plan . I just have to find the right donor. I need a 5/8 I.d. in the bearing.

been a while, but that washer don't look right. maybe thinner/smaller one. no spring?

 

[rocketnorton]

[2stroke_shaman]

How much in the end?

 

[2stroke_shaman]

I paid $200. He is selling off a relatives hoard. Guy bought anything he could and just put it all in buildings. He told me he still has hundreds of saws. Even said he has some nos from buisness closings . Then his wife said "we have some really big saws too" I guess the 600 was a little one ! I'm sure I will be buying from him again.

 

[rocketnorton]

pics of the hoard? imo, ya did ok. know nothin of mac 33, xl 12 are good lil saws. had 4. all brought $100., ea. runnin good, w/o tryin... might be undersellin them.

way I see, yer in $50. ea on 33 & 600. good deal.

The clutch is missing springs. I don't have a photo but I think there are a couple types of clutches that fit that saw. The washer also looks wrong. Its been a while since I had one apart.

 

[2stroke_shaman]

I agree springs and that washer is not in it at all . I ordered a new rim and drum for 375 pitch Oregon .

Back to this ... I spoke with Glen at Oregon technical , he was the man for the job . He looked in old info and found me a close solution to this clutch problem . I found one online with the rim $16 to me. ( oregon 17344 fits jonesred and some homelite) it looks like a little trim on the crank and bob will be my uncle.

[Walter Glover]

What part of crank are you trimming?
If it was me I would do the mods to the clutch and leave the crank original. If a roller bearing fit is the issue, a bronze bushing can be used and work well as these saws spend little time idling. Just thinkin

 

[2stroke_shaman]

Agreed , but I only have to trim .008 off dia. where the bearing sits . I wont cut anything till I have all the parts in hand . Ill decide then. The original is 5/8 so plenty of meat left. The threaded part is 9/16-18 LH.

 

[Walter Glover]

That 'journal' may be surface hardened and 0.008" could remove that hard skin IF you can even cut through it. Best of luck eh! Challenges are fun with these ole girls.

 

[2stroke_shaman]

I file checked it . It isnt soft . Im sure it has a case hard layer . A bushing looks to be best . I have some 660 bronze .

I met with the guy about the pioneer 600 and we made a deal for 3 saws. The 600 poped off with a prime so thats good . Compression feels good, really old gas in it. The 20" hard nose and chain are shot The clutch was stuck (or so I thought). I took it off and noticed no springs and this washer in between the drum and clutch .When the nut is tight the clutch/drum are bound together. What should it look like?

The washer is not original or needed. that is the early clutch used and was replaced with a service clutch assy #470789 that used a inner plate and outer plate inside the clutch drum.
Your 600 needs the 425015 inside sprocket washer installed first, sprocket assy and then clutch. your 3 missing clutch springs are # 425012

 

[2stroke_shaman]

Thanks for the info beavers, do you have a pic of the springs installed? Saw came with a Oregon drum # 66758 8 tooth 375 spur . I bought a Oregon 16226 drum 7 tooth standard rim . Should accept a 404 or 375 . As for the washers , if I cant find... measure and create from blue spring steel?

2 day old carb soup here . That stuff stinks. Noticed this. Pro 88 Remington top , pioneer 600 bottom .




The remmington has a much bigger low and choke lever right left differance.

 

[Beavers]

Pioneer made a revision to the shield cover. the metal is now much stronger and has different anti- bumpers on it for a quick id.

 

[2stroke_shaman]

I found a complete nos clutch for the 600 on ebay . # 470789 Thanks for the info .
