I’m working on a older jonsered 49sp and need to remove clutch ,It appears to be keyed and not threaded,Does Anyone Know Where I Can Purchase A Puller For This Or Any Tricks you May Have ,Thanks

I am wondering if any three-point flywheel type puller will work on this.

There was an older thread asking similar question, unfortunately all that is really there is a copy of the IPL, but that still might be a little helpful if you don't have it yet.

Thread 'Jonsereds 49SP clutch install'

Nov 25, 2021

Question on a 49SP I’m working on. How does the clutch install? It looks similar to how a flywheel goes on a crank with a key but what torques it down?

I’ve busted the key on a flywheel install from not torquing down enough so want to make sure I get this right. Thanks!

I just came across a thread over on AS and it shows some home built pullers:

Jonsered chainsaw help. 70e 621 49sp

I'm looking for the right tool to remove some or all of the clutches and flywheels for these saws. I currently have a 70e and 621 and 49sp and they all look to have very similar clutches and don't look to come off like I'm use to removing clutches on Husqvarna and stihl and others. Would like to...

I should just keep looking and post all at once what I find, the AS thread points to this as a possibility:

I don’t think a jaw puller will work ,You can’t pull on the outside because it just springs up ,There Are 3 holes with threads on top of clutch ,I have a HOMELITE flywheel puller with slots but it wont work as when you line up threade holes with slots the center hole for crankshaft doesn’t line up That thread was about how to install it

Sorry, I didn't mean to imply the jaw puller, yeah, there is no room for that. That is unfortunate that the one you have doesn't match up, I think someone on the AS thread said that you need to make sure and pull it as straight as possible. Do you have the ability to make a custom plate that you can drill/machine your own holes, or know someone who can? Unfortunately that might be the way to go unless someone has the right tool somewhere.

A puller would work if outside didn’t spring up ,I might have to check with the local machine shop if I can’t find one

Post a pic of the clutch so I can compare it to a 70.

Make your own from a washer.

I have a car steering wheel puller that works on most of them.
You can pick them up these days quite cheap.
