Loosen pulley bolt?
06/20/13 at 13:46:25

Finally time to remove the engine from the frame to place the helicoils in the cilinderhead.
Have all the mountingbolts out, but now I'm stuck with the beltpulley.
There is no movement at all, and the rearwheel is keep pushing forward.

Also I thought the tension uou apply on the pulley when loosenng thebolt is bad for the belt itself? The'tooth' can break off or something?

I already thought of taking the sidecover on the beltside off, butI guess there is oil behind it? Since it doesn't run I wasn't able to take out the oil...
Anybody can confirm that here is oil behind it? Otherwise I can remove it, leave the beltpulley and slide the belt off(it now can't get between the pulley and cover)

Thanks in advance for reactions!

For whatever reason either no leverage or just too tight I needed to use a air ratchet to loosen it. At my local bike shop. Try applying rear break when doing it. Put it in gear.

now the fun begins

front wheel against a wall
in a big gear
apply the rear brake
and a brick in front of the tire
you'll either break it loose or spit the brick out the back
the slick garage floor offerred no traction so I added a strap around the tire to the frame.

another way is to put a socket between the pulley and belt and let it rotate to hit the engine casing. the socket should have straight sides and be small enough to nest in the pulley teeth. Around a 1/4" drive, 9mm socket.

I don't have an impact driver, and in this case wouldn't use it.

BTW, unless you're transferring the belt to anouther engine, leave it be. The engine will come out with it on.

Reply #5 - 06/20/13 at 15:08:12 If you put a ratched on it with a long pipe you can get it loose while standing on the right side with your foot on the brake pedal. Ive done it a couple times now, I use a load bar from a flat bed tractor trailer its a 4 foot long hollow pipe. Im not a very big girl but I can do it with no help at all.

This is a trick I've used loads of times: If you have a side cover off and can see some gears (starter gears maybe) you can stuff a rag between two of the gears and then try the nut. The rag is usually enough to jam the engine and doesn't damage the gears. Occasionally the nut can be tight enough to drag the rag through but it works surprisingly often. You'll have to decide for yourself whether you think this will put too much load on the engine cases. But like I said, It's worked for me many times, including on motorcycles.
A nut gun would be a better option though.
My 2c, YMMV etc.

I had the torquewrench on 180 (!) and it still doesn't come of, every time I give more power the backwheel slips, no matter whats in the way of it... Is there any other way to take it off or does anyone has a better idea to do it?

Reply #10 - 06/21/13 at 12:16:25 You really need an impact wrench... if you can get it to a tire shop, or anywhere with one,... they'll have it off in a second... (probably no charge, or very little)... (bring your socket with you) .. or, you can get a cheapy, electric impact wrench from Harbor Freight for $50 or $60...

Have tried two impactwrenches, both without result... Tried to heaten op the bolt and screw it off, but no movement at all...
Guess I have to keep trying until it comes loose.........

Yep, hope he found it.

pretty sure we've established it has regular threads.
sitting in seat, push forward to loosen, pull back to tighten.
