346xp problem

[PEK]

Hi all, if chain brake used when running it cuts out.
It will not start with brake on but will if brake off.
Clutch looks ok, needle bearing cleaned still no go.
With chain and bar off clutch itself normal direction of travel moves but stiffly and turning it the other way solid.

Could be the shaft under the clutch is worn to the point that putting the chain break on clamps the clutch and the clutch cocks sideways and clamps the shaft and you snub out the engine. I have that in my MS261. You may be lucky and it is the bearing between shaft and clutch, which is easy to fix.

Needle bearing?

But would that stop me from turning it anti clockwise?

Need to check the oiler gear. Make sure the clutch drum is aligned properly within the oiler gear before tightening clutch.

I will try that tomorrow, night time here, thanks

Middle picture is aligned
Bottom is not aligned causing the constant engagement of the clutch and drum

Even though the oiler worm gear looks good, the plastic wears and the worm gets wedged between the drum drivers and the pump.

I'll have to keep that in mind.
Thanks Kevin

Just something out of the ordinary that happens on this model. I’ve never seen it on any other, but on the 346, 351, and 353 I’ve seen it 3-4 times

Switch to a rim sprocket setup.

Thanks to all for advice, doing logs this morning, rain later so will disassemble again later and try and get it sorted. Not being able to turn it anti clockwise baffles me though.

The clutch is reverse threaded. It needs to come off clockwise rotation

Aknutter it was the crank that would not rotate backwards.
Any way all sorted now, took the starter plate off, every thing looked fine on the flywheel, part undone the flywheel nut and gave the shaft a couple of hits with a punch, then noticed bits of hard crap dropping from behind the flywheel blew it out with air tightened up the bolt and all seems good, no cutting out and crank moves anticlockwise and chain moves freely on the bar.
So thankyou to yourself,huskihi,singinwoodmac and henry e.

Does your nickname PEK stand for baker?

No, have been called many things but never a baker. Somebody called me it when I was young and that nickname has followed me thru my life.

Ok...just asking....because pek in Slovene means baker....

I know that Bolivian doesnt sound the same as Slovakian....but at the end....balkan (region) is near....so I tought.....just maybe!
