Is '50 190 201' a 500cc part or exclusive to the Atlas?

It's the same... not surprising, as the shift mechanism is identical.

Actually the same spring is used on the 750s and 180 triples, shouldn't be any shortage.

Thanks guys, figured it wasn't an Atlas part as the cylinder head starts '55' so guess that must be the opening sequence if it's Atlas only.

Richard Slater confirmed Piet's wisdom - the spring is common to the 750 and 1000 range....and the 500 of course.

Almost back at square one...

"55" prefix doesn't necessarily mean Atlas.

All gaskets and oil seals begin with "55"... gaskets start at 55 110 xxx (exhaust gasket 55 110 138), o-rings 55 130 xxx, etc.

Laverda has a very simple numbering system, more component/group specific than denoting a particular model.

Cylinder head should begin with "25", as all major engine castings.

What exactly is the problem Nick?

Hi Piet,

The problem is how to replace the small scissor spring 50 180 253 (I think)...How is it possible to install this small scissor spring without removing the clutch?

I have cut a slice out of the retaining washer for 50 190 201 so this thicker spring can be replaced without removing the clutch.

Just spent a couple of hours fiddling to get this sorted and walked away because I know something is going to get broken if I stay with it...

Thanks

Nick,

Just remove the clutch and you'll be finished within 20 minutes, instead of mucking around for hours and getting nowhere...

Hi Piet,

Good advice.

With help from Mrs A got the clutch off and it's almost back together. National Rally on Saturday so will finish the job tomorrow night...

Thanks

Nick :-)
