Rotor puller needed

[rustybronco]

Thanks for the effort to make up the Diagram Brian.

I decided to cut the end of a 12mm spark plug just below the hex and remove the ground electrode. That way I can thread it in the end of the crank and give the swing arm bolt a bit more to rest against when I crank down on it. I feel a bit more secure doing it this way than hoping I get enough 'purchase' on the end of the crank by just sticking something else in the end of it and praying it doesn't damage the threads.

The official Suzuki tool for this job is a slide hammer as illustrated in the special tools section of the GS1000 Factory Manual. By the sounds of it the taper has had Loctite applied to it. Mine was the same and it took a lot of encouragement to be removed, but the slide hammer did the job.

In retrospect, I believe mine to be the same way as yours was. Unfortunately I was a bit hesitant to warm it up to remove the rotor and decided to try the inverted 1/4" extension idea someone else had used with success.

You should see the little apparatus I just made up. It's the bottom half of a 12mm spark with a round headed cap screw bonded to the center of the hole with structural adhesive.

It's very professional looking if I do say so myself.

So is the rotot actually off yet???

Yes Dale, But did you get the rotor off. FANCY TOOLS are no good if they don't do the job.

I'm still at work... let me get home first

And of course, pictures?

 

[rustybronco]

Most definitely...

I would be careful with heat at the rotor...heat tends to ruin magnets and may release the adhesive holding them in. And why in gods name didnt you just bring the crank with you to work...thats what work is for. Working on your stuff while everyone else tends to the parts bins!!!!! Tell John I say hello...HA HA.

I wanted to remove the rotor so I could stand the engine on end to finish draining the oil from it. Years ago I would have tiped it up, removed the drain plug and held it over the drain pan, now I have to work within my backs limitations.

I would be careful with heat at the rotor..

That's what I was thinking...

I'll say Hi to John for you.

With the crank removed from the cases, you could easily tap on the rear of it and knock it off the crank. If your gonna use the clutch that Ed sent then no harm no foul in smacking that around.

 

[rustybronco]

Gonna skip that idea, won't take the chance of tweaking the crank out of shape.

 

[chuck hahn]

I wasnt talking use a 10 Lb sledge..LMAO just tap it all the way around the rim of the clutch and work it off. Unless you go Magilla The Gorilla on it, i doubt youll tweek anything.

EDIT..Its the pressing to the taper that makes the rotor sort of GRIP against the crank and thats what makes it so hard to get off. a few taps and she will most likely just fall off on the bench no problem. If i remeber correctly, the torque spec is something like 30 FT LBS on that bolt..wonder if youd better use a new unstresssed bolt as well???

 

[rustybronco]

Hey that's an Idea... I'll slip the bearing puller under it and put it in our 30 Ton press! Got a spare rotor? (kidding!)

Edit... It's a pretty hardened bolt that holds the rotor on.

I used my I.R. impact that puts out 375 Ft lbs of torque on the swing arm bolt and it still didn't come off. I doubt a slight tap will loosen the rotor.

 

[chuck hahn]

Actually I have access to 4 more entire engines...go for it. Only a day or two delay for me to post one to you....LMAO. Video that for youtube!!!!!

 

[chuck hahn]

"...And the guage is reaching the 20 ton range" Then a sudden deafening POW!!!!!!!!

 

[rustybronco]

Have you ever pressed a wheel bearing out of a spindle before? If you have, you'd know how much truth there is to that statement. The first time makes you jump a bit.

 

[chuck hahn]

Dale..I know this from doing 2 of mine. And maybe i got lucky, but i put my home made puller in and just a few taps with the hammer on the back edge of the rotors and they literally just fell off. In fact I have one to do on one of the skunks soon as i get another day off. Gonna go over to Randys and take one of the starter clutches off for on mine.

 

[chuck hahn]

Yes I have..thats why I know the scenario I posted..it puts a ring in the ears for sure.

 

[rustybronco]

If this method doesn't work, I'll pull the crank and give it a try. The bench is a gonna be a bit messy if I do...
