I can't get to the timing belt to change it. I tried using my Strap Wrench but it just does not have the holding power, neither does my wife.... :oops:

So, Anyone out there with the Special Tools requred or can you direct me to the secret place to obtain said tools?

I have a brand spankin new Goodyear belt ready to go.

I will compensate the loaner, pay shipping and send American Beer if necessary.... :D

Are you having trouble with the flywheel nut? I honestly don't recall whether it's a right or left hand thread :oops: but a sharp smack with a mallet on the socket-wrench handle should do it unless it's rusty. Some folks put the bike in gear and have a helper mash the rear brake pedal to keep things from turning.

You will need the appropriate puller once the nut's off, then I seem to recall needing an outside circlip plier to remove a guide from the crankshaft pulley (behind the flywheel) before sliding the belt onto both pulleys evenly. Yours may be a bit different.

Ok...

Steve, Thanks for the Tip on the Nut. I think I have that covered now.

I also have the appropriate circlip pliers.

The Puller is what I need now. Anyone out there got one rolling around in their Toolbox that I can use....? Anyone, Bueller?

I've heard that KTM uses the same M27 x 1.25 thread on some of their flywheels and their dealers sell the pullers pretty cheap. Hermy used to stock them too, but I think I got mine from NLM. Here are the details:

Sure

What and were is NLM? :?:

I saw that the "club" lends tools, is this still the case? :D

Maybe if I join it would solve my problems....That would be too easy... :oops:

Regardless, I still need a puller! :x

These little faces are ghey! :roll:

Getting plugged in to the Moto Morini Community

Claymore,
There are a few places where the worldwide Moto Morini community converges. Among those are North Leicester Motorcycles. Stuart has done as much as anyone out there to keep these old wonders going. Much of my rebuilt Italian engine came from England :D (your right about the smilies :( ):
http://www.motomorini.co.uk/

Herdan in Pennsylvania. Hermy there likely handled your bike when it was originally imported. He might even remember it! He's the only one there who knows the old Morinis, works part time now and doesn't always respond to email. He's therefore a bit difficult to work with but remains a great resource on this side of the water:
http://www.herdan.com/

The Moto Morini mailing list. This list is based in Australia, and has members worldwide (I think a couple from that part of the US west of the mississippi and east of California):
http://www.smoke.com.au/~ic/morini-list.html

And of course this fine forum. A truly professional website that allows us to share our obsession with the best bikes from Bologna. With pictures and everything!

NLM is North Leicester Motorcycles http://www.motomorini.co.uk

The flywheel thread is common to a lot of Italian bikes. I've heard it said that MZ pullers will work and are only £4. The NLM puller is something like £7.80+vat. People will keep paying £20+ for pullers on ebay. George Lane has started selling pullers made out of a better grade of steel.

The flywheel holder is just a couple of metal strips held together with a bolt and two more bolts to act as pins to fit the flywheel holes. Personally I have a big compressor and an air impact wrench and I never have trouble getting nuts or flywheels off. Battery powered versions are available.

It's important to make sure the puller is screwed ALL the way into the flywheel. Make sure you've taken the spring washer out first and that you've backed the jack screw out. If you have an air wrench then you can just hold the flywheel by hand, otherwise you'll need the flywheel holder. If the flywheel won't release, leave the tension on and warm the flywheel up. A hot air paint stripper does a great job, but watch out for a hot flywheel suddenly popping off.

And try not to get too much heat into those magnets!

A Lambretta dual (double sided) flywheel puller definitely fits. Try www.beedspeed.com

OK...Lambretta dual (double sided) flywheel puller=

27mm 1.25mm Left hand thread and 30mm x 1.5mm left hand thread

I assume that the 27mm x 1.25mm Left hand thread is the correct pattern? Please Confirm.

If so, I think I have enough information to source one on the internet. If not Steve out of PA may have another solution. Thanks Steve.

Getting somewhere, Thanks for all the input Guys.

27 x 1.25 will do the job.
If you can make one or know someone who can there is a drawing here with dimensions
http://www.morini-riders-club.com/thebi ... tools.html

May just be cheaper and easier to buy one though :D

Couldn't tell you the thread size, offhand, but it's definitely not an LH thread, and one side of the Lambretta item fits.

I've got a spare one in my garage; I can send you it if you're stuck!

I think he means the thread on the left hand side!

Left hand side of the big pond???

Seriously, Steve here in the US is sending me a tool to remove the flywheel, Thanks Steve!

If this tool proves to be incorrect, I will ask the masses again for help. Thanks for all input!!!
