Pp 475

While I'm looking for a carb for my PP325, I decided to tear into my PP475. Cleaned up the cylinder so its good to go but not sure the piston will make it. Found air filter material stuffed in the carb and likely it made its way into the cylinder. Piston is NLA so I may have to get a Meteor. Other than that saw seems in decent shape.

SAVE YOUR MONEY, dont waste it.

I sold/traded my last OEM 475 piston so cant help you there.

Meteor is the worst choice IMO.

Drop in is a BB372 no work involved.

Open pin bosses 064 is a good choice too.

Help me out with "open pin bosses 064" piston. You are saying that a Husky BB 372 p&c is a drop in? As good perf. As stock 77cc?

Bob,

What he is saying is that the connecting rod, where the wristpin goes is too wide to fit into the piston as it comes to you.

You only have to remove a bit of material to widen the area to fit the connecting rod.

You actually have to remove quite a bit of material to fit the 064 piston on the 475.

Although the 064 piston makes a ton of compression with the stock base gasket, if I was to do it again I think I would try Kevins idea with the BB piston.

Thanks to all u guys for enlightening me. Any recommendations on a good 372bb piston kit?

Nice trio...here it comes..

So, which one cuts the best? By cut the best, the one you would grab to cut all day long. Most wood cut with least effort, less tiring, etc, all the normal factors. maybe even mix tank to cord ratio, and bar oil usage. Overall, best one.

TIA

I'd take the one in the middle. Easy to get parts for and besides that, its not a Sthil. :hmm3grin2orange:
 
I picked up another S25DA and a 3600 this past weekend. Need to locate a muffler(several, actually) for the 25 and an air filter + top cover for the 3600. I thought the compression on the 25 was a little low at 130, but everything looks good and it fired on a prime. The 3600 on the other hand had 170 psi and should be plenty strong. There was some scuffing on the exhaust side of the piston, but otherwise looked good.

Need to get a better pic.

I've got all 3 also, well a Jred 2171 instead of the 372 and frankly the 2171 is ported. When I have the need for that size saw I use the Jred until the chain needs attention then pick up the PP475.

I never take a Stihl with me because those are made for selling, not keeping and running.......

The 475 you got is a bit stronger then a stock 475 as well.

The parts thing is the main deal to me though for a steady user. 475 parts are not as easy to get plus the saw as a whole is a bit fragile compared to the modern Husky.

I got a 475 too. This one is 445 70.7cc quad port like the 65cc little brother. I have only seen 3 so far and 2 of them is right here.

3000fps and me. Funny thing is I passed on the one Roger got and then wished I had gotten it later on.

On the 2171. I rebuilt one of those once and swore never again. No local dealers and no used parts for one, except online at double prices of 372.

If I had to choose between the 3 372.

For some reason this 440 with the DP enlarged deflector and side outlet is a monster in the cuts. 4 stroking at 13.7 stock and clears up as soon as touches wood. I'm impressed. My stock muffler 445 peed a little before the little test session. :msp_scared:

Yeah,


I'll have to vote for the one in the middle too!
Maybe someday I'll get mine running right!!! :D
