clutch cover removal tool

[basketcase]

This is FYI.
I had to pull my clutch cover and needed the special tool to push out the end of the crank. They were kind of expensive on line so I decided to make my own. Well it turns out that a M22 x 1.5 is a odd size thread. So i sourced a wheel stud for a big truck at NAPA. Turned down the end to .620 diameter x .530 long. Then turned a .370 diameter x .125 long. And put a 10 deg angle on the .370 diameter. Lock a small pair of vice grips on the knurl, put some grease on the tip and the threads and.......viola......clutch cover removal tool.
I know, I know....I'm doing things in inches. Thats the way I've been taught and old habits die hard.

____ I'm providing a zoomed-in view of your pic, so as to allow for better 2nd.click-expansion.
If you're agreeable, I'll substitute it for your original-pic, (instead of leaving the improved-shot posted here in my post).

Thats perfectly fine with me Bob.

The first time i tried to download the pic it was too big. So i had to reduce it. So thanks for making it bigger for me.

The next time i'm welding stuff, I'm gonna weld a nut on the end so I dont have to use the vice grips anymore.

____ I was tempted to just go-ahead & do what I've now done but, thought I ought to ask first, (cuz otherwise it may've been a bit upsetting).



" The first time i tried to download the pic it was too big. So i had to reduce it. "

____ In order to show the subject-itself large enough to be well seen, such a normally-pictured entire pic as you originally tried to up-load is then too large to be accepted, as all of the included excess-area of the pic wastes data-space. _ But after the excess-area has been cropped-away, then merely the subject of the pic alone, can then be shown sufficiently large-enough. _ (So it's nice to have digital-picture software with a cropping-feature.)



" I'm gonna weld a nut on the end so I dont have to use the vice grips anymore. "

____ Rather than doing that, you could possibly instead add a pair of lug-nuts and jam them TIGHTLY together (nearest the outer-end), so that you could then wrench on just the outer-nut (pretty-much as if it was welded-onto the threads, [as it becomes pressed even tighter against the inner-nut]).


Glad to Help-out,

I used a plug that had been abused by a previous owner looked like a chisel had been used to remove it. I brazed a M8 nut into the centre bored a 6.8 hole through the nut and plug then ran a 8mm tap through both.
I shall have to run a die down the bolt or find another with a longer thread. I like your idea of machining a locating nipple on the end may well copy that idea.

I have 2 tools for removing the clutch cover.

I had a boogered up plug too that i was going to sacrifice. But then i found the wheel stud and the plug was saved from spending the rest of its life in the tool box.

Is the top one a slide hammer?
And the bottom one is a claw hammer! I would be afraid of cracking my irreplaceable cover.

Yes, a slide hammer is effective and safe. You don't have to touch the crankshaft.
The claw hammer was what I used to use exclusively until I made the slide hammer. I never had a problem with that method. The point of effort is at just the ideal place, as the back of the hammer levers against the clutch, the cover easily comes free. The only unwanted effect is slight marking on the inside face of the clutch cover. Our bikes have become so precious, even that is an inexcusable sin now!
Of course, all tools have to be used intelligently for good results.

As I recall the clawhammer method is illistrated in one of the Mick Walker books so it's a tried and true method. This works OK if the interference fit of the crankshaft in the outer support bearing (housed in the clutch cover) isn't too tight. If this interference fit is tight, the claw hammer method risks breaking the clutch cover. Good practice is to heat the cluch cover around the inspection plug which will either expand the bearing enough to easily slide off the crank or the bearing will come out of the clutch cover. Matt
