Hi Chaps
you might recall that I've recently managed to get an old rattler of an SF2 woken up and back on the road. Well, it's all registered and so far I've covered about 500 miles on it. In the interests of fairness, I should tell you that I've deliberately  been alternating it with my Motobi Tornado as somebody here was recently asking about the differences and I opined that the Benny was more fun. With hindsight, I'm happy to report that the Lav is superior in just about every respect, though possibly just a little too good, I'm used to a challenge!

I've had the usual shakedown issues but one problem persists- an irritating oil leak from under the dynamo belt cover. I 'think' it's coming from behind what looks suspiciously like a sprag assembly, on the end of the crankshaft. Might I be correct in assuming that there's a crank end oil seal and that it's leaking? If so, do I need to borrow/buy special tools to get the sprag off and, please if there's a God, can I whip out the end seal without splitting the cases? I really don't want the hassle of tugging this motor yet, I'd hoped to enjoy some of the summer on it first!

Any suggestions gratefully received.

Cheers
A tutto gas

Yes there is an oil seal behind the starter clutch. Everything is straightforward other than the nut holding the whole mess onto the end of the crank has left hand threads.

The bike looks fantastic Paul.
It makes me feel guilty that my silver road SF2 looks too tatty to put out a pic of; I`d love to send it to Lothars German Finishing School  :D
You are right that these bikes take time to grow on you. You will find that some particular ride will trigger something and suddenly it will all feel very right and then it is too late, you are hooked.
There is the large oil seal shown in the pic in the crankcases that the starter freewheel sits still in (only rotates when the starter spins). There is also a seal outside the needle roller of the freewheel which spins all the time. Both are easy to replace, check that the surface the seals sit on are in good condition.. To remove the starter clutch I cheat and remove the reverse thread 24mm nut and holding my hand to catch it, give a quick dab on the starter, it usually jumps loose (I?ll no doubt be shot down in flames by the real mechanics here). Otherwise any 2 or 3 legged puller should be able to grip the pulley (not the sprocket) and loosen it with a tap from a nylon hammer. If you take it off it pays to check that the starter clutch springs are intact and the plungers are free to move in there. For reassembly you have the freewheel assembled in the starter clutch, make sure the key isn?t sitting proud to snag on it, line it up with the keyway and slot it in place. The nut does not need to be super tight, I carefully torque it to two taps against compression with my trusty nylon hammer to the 10" socket bar (here come those bullets again).
Enjoy the summer

OK, just spoken with the smiling credit card assassin, Richard Slater and the seals have been ordered. Sharpening a wood chisel later, ready to attack whilst repeating the mantra "left hand thread, left han..." I'll keep you posted!

Amazed and really impressed at the traffic on this site, it's a major resource, is there a donations button, or shall I just let you all buy yourselves a pint?

Thanks again.

Paul, I forgot to mention that you remove the startermotor sprocket and chain together with the starter clutch and fit it again together with it.
It dumped a mass of snow here yesterday, just when it felt like spring.....gotta melt soon and let these bikes out.
Ciao

I just drool when I see SF's now!  and that one does look very nice!
Gives me inspiration to get my arse into gear!

The wife wants to ask, which way round does she fit the rubber seal to stop it from leaking? does it go on the outlet valve? or does it go one the starter spindle on the other side?
Managed to make that one work this morning but the she said it was leaking quite a lot after some heavy cranking :D

just a quick thank you. Having received the two seals from Mr Slater yesterday, I  resolved to fit them today. It was all remarkably painless and I appear to now own a non-leaking SF2. This is good news as SWMBO was giving out acres of earache about the oil on her drive!

Thanks again, it's much appreciated. This is such a great resource that I'd go as far as to recommend Laverda ownership to anyone seeking the true path of Triciolore as it just makes life...easier.

Take it easy
