tanaka/hitachi CS40ea rebuild.

[nenicu]

Just to see that i know what i'm talking about. Also i work on anything i can,2 stroke and 4 stroke.

 

[TBS]

I wish we could get some of the saws you guys get overthere.

Rechecked and the earthquake piston a mil smaller so that idea is out.

 

[nenicu]

42,5 mm =Stihl MS 250 piston. Similar in shape.

I got my Tanaka 5601.

 

[Conquistador3]

I wish we could get some of the saws you guys get overthere.

And I wish we'd have the spare parts price you get over there.

 

[TBS]

Parts are expensive for you guys over the pond.

 

[TBS]

Hopefully tonight or tomorrow I can get this thing back running along with my Ryobi, plus test the 56cc and 40cc.

 

[nenicu]

What piston you got?

 

[TBS]

Just sticking with the original with a little clean up. I had a new set of rings.

This project got put away for awhile do to other financial priorities and weather but now I've got time on my days off and a muffler so it will be running in wood by Thursday.

 

[TBS]

Well maybe you guys can solve this little problem. As stated earilier i put this saw away for a while, it turned freely, lubed well when stored. Took it out today and it was locked solid!! I did get it freed up but its hard to turn over. Recoil, clutch, and flywheel were removed.

 

[LegDeLimber]

I would remove the muffler and take a look inside of the cylinder,
Before trying to turn the engine any more ( other than enough to look in the exhaust port).
Also take look into the spark plug hole.

Could be that:
a cir-clip has popped out.
Ring locating pin lose.
Ring has snagged.

How about the clutch cover, is it rubbing the clutch?
Is there a chain brake that has been triggered?

Could any bar & chain lube or fuel have leaked into the crankcase?
Was there enough assembly lube used that it may have drained into the bottom?

Just my first thoughts of things to check.

 

[TBS]

All of those items were removed and the engine is seperate from the tanks. I got it freed up.

 

[TBS]

I acquired a complete not runner off ebay this morning and looking at the pictures it just threw a chain and got returned to the store. I'll have plenty of parts with both to make a runner ane One cylinder will be my first attempt at porting.

Anybody know where to buy parts for these Tanaka saws? My CS40ea needs an air filter...previous owner took it off before I got it. Ebay doesn't seem to have one..

Thanks..

 

[TBS]

The other saw came and is in more or less new condition.

My Hitachi/Tanaka saw looks like it's fairly new. First saw I ever worked on that didn't run but there wasn't anything wrong with the saw...previous owner put some kind of fuel in it that wouldn't burn, maybe his kids put Kool Aid in it instead of fuel..
