Dolmar ps6100 stuck clutch drum

[mcdougy]

Was running the saw today noodling some white oak. I think I heard the rpms rev like I was running low on fuel, then it locked up to a quick stop.
Filled it with gas and it wasn't completely out.
Restarted and the chain was active at idle, So I hit the chain break and it stopped and shut down immediately.
Restarted fine 2 or 3 more times but same scenario...active chain at idle and complete shutdown when engaging chain brake.
Started taking it apart to inspect the clutch.
Can't get the clutch to come off.
Seems like it's really on there, can't even get a wiggle out of it with pliers on the attached sprocket.
Do I need to use a bearing puller?
Any ideas on what a guy should do to get the drum off?
This saw has worked perfectly for the last 7 years till now.
Thanks for the help
Matt

Sounds like your clutch is locked up.

As for the drum. If you have a vise grips big enough you could put the sprocket on the drum and clamp the vise grips to the sprocket like you would a nut, and try to spin the drum. Use the sprocket so as not to smash or crush the drum.

If you don't have a big enough vise grips you could weld a flat bar to the sprocket and use that as a wrench on the drum.

You could also weld a nut to the sprocket so you could use a wrench, impact gun or ratchet to spin the drum.

Just put a piston stop in or some recoil rope down the spark plug hole.

If the drum does not brake free from the clutch you might just have to spin the whole works off as one unit.

Good luck!

As a last resort you could try to drill and tap holes in the drum to match a Stihl flywheel puller.

I would not use excessive force!
You might break the crankshaft in doing so.

The drum not coming off without force applied is a bad sign.

Good luck, take Your time and figure out what happened.

I’m thinking a broken spring is jammed up in there. I’ve had one or two stuck like that. Some careful prying will get it. You could try a puller but be gentle and make sure it’s not grabbing the clutch along with the drum.

What kind and size is your saw? might make a difference. From the comments we are assuming you have an inboard clutch.
(EDIT)
OOPS I read the thread title.

Any of the above sound plausible. I would add hose it with WD40 and give it a few minutes to work first. If the drum is really locked on to the clutch I don’t see why you can’t use a cord for a piston stop and take them both off together?

Could have some of the white oak noodles in there jamming it up.

He got the clutch off, a spring broke.

He is looking for a source to get new parts from.
Check the recent posts in the Dolmar/Makita thread.

Noticed that.
