Pioneer chainsaws

[VA Farms]

Hello All,

First off, thanks for all of the knowledge I have learned reading through your posts!

I'm working on a saw that use to be my grandpas. It is a Pioneer 1150 s/n 41485 (serial number could have more digits, but kind of messed up toward the end). It also has 1150 on the air filter cover. Piston and cylinder are toast and the crankshaft end is goober'ed from flywheel removal. Looking on line to research parts, the few numbers I can find don't seem to match up, but I'm sure parts or motor could have been swapped over time. Is it an issue of the parts manual I've found is to new, or other parts swapped in? Is there any cross reference that shows what parts swap between saws? It seems the 1130-1160 are close to the same (maybe no auto oilier on some) and the 1200a and 2270 use this cylinder block, but I'm not sure what other parts interchange. Thanks for any help you can provide!

First off it has-
cylinder block 428190
Connecting rod 427664
crankcase 428190

What I found in the Parts manual (Part Num 430255 dated 11-72) for the 1150 says it should have-
Cylinder block 428512
Connecting rod 471336
Crankcase 471602

The cylinder number 428190 is from a 1200A. Looking through the IPL's there doesn't seem to be much if any difference in the cylinders in the 1100, 1150, 1160 1300 etc
The 1160 and 1150 share the PNs you have shown from the 1150 IPl's
Over time PN's may have been changed but I have no bulletins to explain why.

I'm going to send you a private message which will appear in your Inbox, upper right corner of the screen beside your VA farms sign in name.

It looks like someone thought used motor oil was good for 2 stroke mix . I know it isnt but that is the most crap I have seen inside a saw. Explaines the shot bearings and seals . I have serious doubts any of the internals are much good . It did have 135# comp on a oily p/c . But has a good case that I needed .

crickets.... someone is doing something!

Held my new P41SH in my hands finally!
Will check her over tomorrow in the shop! Yippee

Those saws have tons of torque for their displacement.

Pics

Edit:
Very dirty but everthing quite good condition. 135psi comp with bar held in vise. Excellent cylinder and zero scoring on piston as checked at exhaust port
Two piece ignition has spark
Rotten fuel in tank and toasted that section of fuel line. Fuel cap fits great no swelling evident
Got her ripped apart for a good washup
More later

 

[Walter Glover]

Oh yes this might be my cheapest purchase and overall best bargain
Yippee

 

[Walter Glover]

Back together all clean. Need a carb kit and a chain should be good

Edit:
Need a safety return spring now as it dissppeared on me! Have to make one i s'pose.

Couldnt wait to hear it so squirt fuel and she roared to life haha

 

[Arrowhead]

Nice. I bet it cleaned up great. Even has the original starter handle and the plastic guard on the handle doesn't appear broke. I can send you a spring and a couple nos P41 decals for the side covers. PM me your addy.

 

[Walter Glover]

Thanks Arrow

I doubt this saw was ran much in its life. Very little carbon deposit in exhaust. Bar plates are pristine and all clutch parts are like new. Btw are these pioneer rim sprockets an available size?
Picked up a carb kit after curling this morning. Tomorrow should see it running.

 

[2stroke_shaman]

I'm no expert but I have been playing with clutches lately . I bet it is a standard 7 rim, available in many tooth/size/gauge choices.

 

[Walter Glover]

Thank you. Looks to be regular Stihl sized spline for sure. Just wondering how these torquey saws would run 8 tooth for more chain speed options
