MS660 chain oiler issue

[canoehead]

seem to have a blockage somewhere inside the chain oil feed system probably very fine sawdust from milling, because thats when i noticed the problem, (lack of oil flow), not the pick-up tube but inside the body of the saw somewhere, and an air hose wont clear it, and the oil filter wasn't clogged or anything, in-fact it looks pretty clean, any ideas about how i can clear it?

 

thanks

Fill the oil tank with petrol, make sure the oiler is turned to max and use it for a bit, (a spark arrestor is probably advisable, but a bar of fire is very cool as well and does not burn long)

[canoehead]

thanks will try that. and bar fire sounds like either a) a bad juggling act waiting to happen, or b) something that probably occurs out here quite often in the summer.

 

anyway, thanks sounds like a good tip.

I am guessing that you have checked the oiler holes in the bar?

 

I usually just pull the sprocket and clutch off, remove the oiler and clear the blockage with a bit of wire and a blast of WD40.

 

Usually quicker in the long run!

Hi canoehead/Spud,

 

Spud - do you remember my 066 did this and was a right pain? I did the oil tank full of petrol thing, which didn't shift it. Not sure what you did to it in the end?

Yup - exactly as described - strip the kit out and shift the plug of wood chip if the pump is plugged - I do remember your breather was blocked though - you can see the little turd of crap I pushed from it: -

spud,

 

is there an oiler hole behind the clutch assmbly? had checked the one behind the bar and tried air hosing from that side as well, and tried getting a piece of wire in, which only will go so far before it hits what feels like a bend in the oiler duct.

 

thanks rick

The oiler is mounted around the crankshaft behind the clutch assembly - generally fine woodchip is sucked past the pickup filter and ends up compacting in the oil pump inlet hole.

 

I would pull off the clutch - it has a left hand thread so spins off clockwise!
