Pioneer chainsaws

[cbfarmall]

You see that and it's no wonder some saws overheated and scored.

 

[ML12]

wow. well done. what paint and paint method are you using on those?

engine enamel and 2k clear on top. Holds up pretty well

 

[flatsfisher]

looks fantastic. I recently did 2 Macs with 2-part epoxy primer and 2-part automotive urethane. no clear coat. 2 coats of each.

Ha ha! That’s a good amount of 40 year old gunk!

Making progress. Saw is now 1 lb lighter

 

[cbfarmall]

Wow, hard to believe that's the same saw. Homelite had problems like that with their 925s. I remember a divider on the clutch to help keep gunk from traveling across the case.

So was that a whole teardown to get it that clean, or just a lot of brake clean and compressed air so far with a teardown yet to come?

 

[xl130]

WD40 and air air compressor for about 30 minutes. At least half of that oil soaked saw dust ended up on my face!

Not going to go all the way into it. Top end is in great shape.

Just a good tune up. Cleaned the exhaust and exhaust port. Pulled the clutch , fuel system and ignition. Staring at the seals and it seems silly to not change them now . Anyone know the replacement seal number!

CR5926 and Dichtomatik 15X25.5X4.5TC. Have to use a thin enough seal on the PTO side else it will protrude and drag on the clutch.

Do you need one of each or are they the same both sides

I’m looking to for a bearing for my P50. Unfortunately it has a lot of play on the drive side shaft bearing.

I was told that CR 6202-C3 open was that correct replacement. When I look that up on Motion Canada it gives a few options with that part number. Can anyone confirm which one is one the options is the correct one??

CR5926 for the flywheel side, Dichtomatik for the PTO side, one of each.

Some of those designations aren't familiar. Generally, you want an open bearing but alot that I buy have shields and seals that I pop out. I see an electric motor rated bearing which you should probably stay away from. They sell a plastic caged bearing. Dealers choice there.

This one here looks to be the best option I guess. Alm others are electric motor quality.

6202-c3 is in the list and it’s open with a steel cage

 

[xl130]

Lol.wrong link. This one looks the best.

SKF 6202 TN9/C3

 

[pioneerguy600]

That is the one you want for a chainsaw gasoline engine, the -c3 designation is for heat expansion gasoline engines create.

 

[xl130]

I did some reading on the SKF resources in an attempt ti better understand a bearing code. For SKF 6202 TN9/C3, The TN9 designation refers to the material that the bearing cage is made of and the C3 is the heat tolerance exactly as PG600 confirmed!

I guess it would be helpful to know what an engineer would use for a two stroke engine. Possibly the TN9 material is not recommended for the application of a two stroke engine.

This is from the SKF website.

I've always just used brake cleaner. I don't know why WD40 never occurred to me. Need to give it a try. It certainly wouldn't evaporate as fast!

As for compressed air, one of these changed my life. I'll never use another air/blow nozzle. Pretty much doubles your effective nozzle pressure and has a built in regulator valve in the trigger action. Can go from a super gentle wisp to damned near cutting yourself with the pressure. A face shield is highly recommended when using one. The only drawback is it needs a decent sized tank to keep the compressor motor from constantly running. My 30 gallon tank seems to keep up pretty well.

Looks similar to what I use now. That one may it’s a bit more powerful though. I’ll putting on my Christmas list for the wife

This is the one I picked up and Canadian Tire awhile back. The tank does run quite a bit though when I run the nozzle for long periods.

Works great for cleaning saws and blowing out brake parts when changing pads and other parts. Will absolutely decimate most Pioneer paint!!

Well don’t think I’ll be doing the seals at this time! Dichtomatik isn’t available until June 2023! Think I’ll need to find another seal manufacturer or a different supplier!
