Leaky clutch side crank bearing

[NathanInAdelaide]

Hi all. Probably a stupid question but if i have a leaky crank bearing do i have to crack the case to replace the bearing? Or is there a way i can seal it up without removing the crank?
Cheers, Nathan

All bearings will leak, its the oil seal that stops the leak and they can be changed out on most saws without taking the chassis apart. What saw are you working on?

All bearings will leak,

haha

Even my high speed muffler bearing?

Working on an 075, but think I have a similar problem on a few old saws here.
Will see if I can find info on oil seals. Thanks

Ok so I have done some more testing and it looks like it is the seal on the selector for the bar oil.
Couldn't hear exactly where it was coming from and when I got to the crank seals they were ok (soapy water test!)
Any advice on this one? Haven't had a chance to look at pulling it out to see what the seal is and it is bedtime here.
Cheers

Hi again,
I have replaced the two o-rings in the oiler control knob. Still seems to leak here? Any one got any suggestions?
The two o-rings I replaced are the 9646 945 0780 and 9646 945 049.

The other thing is that when I pressurise the case the oiler drive worm pops out? This shouldn't happen right? Not sure how I am supposed to get it to 7 odd psi?
Any advice?

Cheers
Nathan

Ok so it looks like the oiler just spins and lets the worm pop out? Is this ok?
Cheers
