PP 655 BP
« on: January 05, 2016, 09:54:20 am »
Looking for any advice or things to look out for, replacing the piston on my recently acquired 655bp. It is indeed a bp, pulled the muffler and can clearly see the boost port on opposite side of the cyl.  But was noticing that it had a standard piston in it. From what I have been able to gather, early BP's were this way. Latter ones utilized a piston to take further advantage of the BP's function. Open skirt on the piston on that side. I have got a new piston here for it. Just not sure when I'll get started on it.

I have not even started the saw. And probably doing more work than is necessary, for what little gain might be achieved. Don't know. I figured what the heck. If thats what they finally came up with for this saw, then I will do it also.  ;D These Pioneer based saws are new territory for me. So any things a newbie needs to know about these when dismantling or putting back together would be appreciated.



Gregg,

That's a nice looking 655!

You won't be able to tell which piston is in it till you have the cylinder apart. The only difference is the piston skirt bridge is knocked off on the BP piston so the lower portion of the boost port will be open longer. You can easily mod the non BP piston to be the same.

Nice looking saw Greg.   I really don't know a lot about these saws myself having never taken one apart.   From what I understand though these
saws really run good.   Pretty cool.   Take some pics when you tear it down so we can have a look of what is inside the baby.

Thanks for the info! DUH! I guess it would be easy enough to modify the piston thats in it.  I think I will go with new piston though. Don't trust my "modding" skills.

Will do Roger. I bought this saw from Bob, (rdunshee).  He said it starts and runs great. But he never cut with it. I will certainly do some cutting with it. Can't wait.  I have got to run several of these saws at GTG's, so I know what they are like!  LOL JUst never owned one, till now.
I think while I'm at it, I will put a full wrap handle & dual spikes on it too. Decals also. I certainly don't NEED a saw like this, but should make for a good GTG saw if nothing else.

Gregg,

To see a clean one, they are certainly impressive.
We should share what we know... someone may learn...

Nice Gregg.

If you don't have the manuals I am attaching links to that series and the large P series Pioneers which really compliment each other.
If you need any special info, a friend of mine collects P60's and has has them torn apart right down to pieces and restored so I can ask him.
If you put crank seals in it, Be carefully pulling the oiler gear and make sure it's position is carefully measured so you can get it back in the same place.

The adapter / reed block to carb are fragile and often crack. They are getting hard to come by so be careful with them.

Don't leave the fuel cap screwed in when you're not using the saw. If there's any ethanol in the gas the cap will swell at the threads and can be very difficult to get off and restore.

Use the decomp when you start it. They can be a tough pull and kick. Not smooth like a 5200.

The P series are generally pretty easy to work on.

Thanks for the tips & manuals Tim. I think Bob said he had replaced the oilers, and they work well. So hope not to have to do anything with them. I'll have to check the fuel cap tomorrow. I never would have given that a thought. I will take some pics when ever I get to this thing. Dang cold weather is not conducive to me out there working on a saw.  LOL  I know...gettin to be a wuss in my old age. I do have a big 150,000 btu kerosene heater I could run I guess, if I can't wait and get ambitious.

The only part that I would like to replace, is the recoil starter assembly. The cover is kinda rough shape, but works well. So I will probably be looking for one of those. I found one that looks like will swap, but have to repaint it yellow and swap the internals. Its Pioneer green. But thats for down the road and warmer weather.

Thanks again for the advice! Eh!
Gregg,

These saw were also built off the Pioneer-Partner P-65 saws.
When they closed the plant in Canada, most of the parts ended up in our warehouse.
