Hello!

Another question. Do someone know,, where to find-buy a semering-sealing that is placed under the front sprocket?  The sealing rubber is in metal housing. I can't find any picture, but sure you know about what I'm talking about. On laverda-paradies I saw it, but only rubber, without the housing. I made one stupidity when dismantlling froint sporccket , so I broke the housing.

thanks
 
on this link is number 55  https://www.laverda-paradies.de/shop-1000-46-de.html 

but I would need the housing to,, not only rubber. Because is bent  and destroyed, because my stupidity during sprocket extraction.
 
You're referring to the oil seal (Simmerring), standard part. I assume you've damaged the inner sprocket cover and need to replace it or get it repaired. As requested post a photo.

Do the bike and yourself a favor. If you have problems disassembling and installing components seek help from someone with the necessary skills and quality tools. It may cost you more than you'd like to spend, but in the long run will save you a lot of frustration and money. No insult intended!

Regards,

**Edited for removing nonsense**
I would suggest to take Gerald for serious. Next thing I could see happening is that you might bend the fifth gear selector fork when inserting the new sprocket. This would mean that you'll have to split the engine cases to fix it. As a starter, stay away from using brute force or improper tools.
 
That part number 55 does have like a metal housing enclosed in the rubber seal, if you look at your  damaged one I think you will find photo would explain much more if you can do.  chris
 
Hello,
who or what tells you the seal from laverda-paradise has no
metal enclosed?
As you said it's under the sprocket (behind it) it should rather be
No. 57.
Besides from that it's a standard item, not especially built for Laverda.
So if you have a technical supplier or bearing shop near you should be
able to get it there. Dimensions are 45x60x7.
Nevertheless, photos are always helpful...

Ernesto is correct. It's just a standard seal. There is no separate "metal housing" that you refer to. Seals generally have a steel spine encased in the rubber, but some seals have a metal casing on the outside. If your old seal has an external metal casing then I'd guess a previous owner installed the wrong type of seal, which may be why you're having problems with it now.

The inner lip of the seal runs on a steel spacer on the shaft between the bearing and sprocket. That's the only separate piece of metal I'm aware of that's associated with the seal.

You can see in the photo below that the seal has a rubber (or neoprene, whatever) outer perimeter.

Seal ID - TC 12576 45X60X7mm

Cheers,
Cam

Important!!
When you replace the lip seal (Simmerring in German) be sure first to bevel or round off the sharp edge of the hole in the aluminium gearbox housing first.
Otherwise, you will destroy the new seal when you try to fit it.
Good luck,
Steve
