Pioneer 450

Hi guys. I am new to the forum. I found this site while searching the net for parts for my Pioneer 450. I haven't found parts, but did find this thread that petesoldsaw started months ago. He was looking for pics of Pioneers, so here is mine.

It has the yellow reservoir caps rather than the black caps shown in most photos. It also has the problem that seems to plague all the Pioneers of this vintage; the primer system. You can see that I have repaired the primer button with a bolt, and the sight glass has been epoxied back together. Inside, the inlet valve disc disintegrated and I have cut replacements out of various materials over time. I think that the current one is old inner tube that keeps expanding with time. I should replace it with neoprene, I suppose.

In order to get the pump to prime, I have to fill it with fuel and then tip it with the bar pointing up. Then some vigorous thumb work will eventually get gas to the sight glass, as well as all over the repaired primer button. But, when I see fuel, I know she will fire.

Dad bought this saw sometime in the '60's, slightly used. I put a couple of primer kits in it over the years, so, thankfully, the diaphragm still sucks gas. Neither the carb or mag have ever been touched to my knowledge. I have looked for a reason to abandon this saw, but have been reluctant to as long as I can get it to run. It only gets a few hours of use each year now. It is sure hard to kill these old saws; they take a lot of abuse. The old flocked screen air filter has lost all its flocking. The muffler is rotted out. The fuel cap has lost its liner, so I use a toothpick to keep too much gas from spurting out.

It's not very fuel-efficient, but has lots of low end torque. It is pretty heavy though. It is great for bucking, but is a handful for felling & limbing. Funny I don't remember noticing that 30 years ago. Not too many safety features, as you can see. I still prefer manual chain oil pumps.

Having read much of this thread, I won't even ask if anyone knows where I can find primer parts. However, I did pick up a useful tip from the poster who said that he uses a syringe to prime his saw. I'll remember that one.

Does anyone know of an electronic ignition that they recommend for this saw?

Thanks, stewie.

1074

Well I e-mailed Mike Acres & he responded quickly. However He has been out of the covers for quite awhile. He did say back when he could get them he sold about 25 a year. He also went on to say that lately he's been getting an inquiry for them about once a week. Hmmm...

Nice 450, looks like a good old survivor and good for you to keep it running. The Nova Module would work on that saw, I run a couple of them on old vintage saws that you can`t find points for and they run the saws just fine.

I think this is the filter you need. The guy selling it has parts that he hasn't listed on wbay too.

Petesoldsaw P28

Here's a few pics of the P28 I picked up for $25.00 late last year.It was a one owner saw.The chain was shot when I got it,bar was rusty but it is the original, still had a lot of the original grey paint on it.I put a used muffler on, it was missing form the saw when I got it.Before putting the muffler on I checked the piston and what I could see of the cylinder, there were no scratches or scoring that I could see.That's what you should do right? Cleaned a bit of the dirt off,new gas in it,and it fired up after a few pulls.I think it was a little hard to pull though.How do I tell if the decompresion valve is working properly?Could you guys take a look at the closer shot that shows a metal spacer and bolt under the one bar nut .What is that for? I can't figure it out from the IPL.
Thanks Lawrence

 

[briantutt]

Isn't that piece a safety feature? If you throw a chain it's supposed to stop it? Looks like the bolt makes it a replaceble part incase it gets wrecked in a throw. My 362XP has a similar item on it. It's flat but that's what it's for.

Pioneer 1073 bar tensioner part needed

I am looking for item 104 in the attached diagram for a 1073. Mine has the tab broken of the back that pushes the bar forward I am assuming. Anyone know where to get one?

 

[WesternSaw]

1073 parts

Brian there are many dealers on ebay that would probably have that part.When you do the ebay search type in Pioneer chainsaw parts.A couple that come to mind are Killians Online,Chainsaw Hot wheels the fellows name is Randy and Rottmans in eastern USA.Good Luck

That is your chain catcher, not the stock one but looks like a mod someone has done , should work good though.

P28

Hello Jerry would you happen to have a picture or drawing of the original part? Thanks.Would like to find a service manual for the P28.Would also add that the throttle and the hold for the throttle and the safety lever or whatever it's called is very finicky

[artie__bc]

Artie, the covers all cam into the carb manifold so are all the same. The P26 and 1074 filters and covers are identical.

From personal experience I can say that they are not the same. I helped a friend of mine change his 2071 over from Pioneer carb to Tillotson. The parts came from a junked 2071, which had no cover. The original cover looked like it would fit, but would not because the filter cover fastener pin was either too far to the front or too far to the rear, I forget which. The mounting adaptor for the Tillotson carb is different than the one for the Pioneer one and has the filter cover bracket mounted differently.

EDIT: I'm saying that the P26 and 1074 covers are different, just that if one has a Pioneer carb and one a Tilly, they're different.

Well I have been cleaning and painting up some of the old Pioneers. You may remember this old NU 17 that was rescued from an abandoned logging camp.

Well it looks different now!

 

[briantutt]

Nu 17

Awesome job Does it run too!

 

[WesternSaw]

Nu17

Jerry's working his magic again.Real nice Jerry!
Lawrence

 

[pioneerguy600]

This NU 17 was completely rebuilt with all NOS parts internally. It has a new crank, new bearings and seals, new piston and rings with all new gaskets.New connecting rod and rod bearings on both ends.The starter gear, recoil spring and rope are all new also. The carb is also a NOS Tillotson so most of this saw is new parts.
This saw starts and runs like a new saw would. The front handle is all that is needed to complete this saw.
The RA that I got a couple of weeks back is almost complete now as well, its totally rebuilt mechanically and has been completely stripped of paint,then etch primed and now completely painted this evening. I will post some photos as I took picts of every step of the process for the first time in all of the rebuild/ restore projects that I have done.
