I am in the process of setting myself up to rebuild 180 cranks and would like to communicate with anyone who has done this.I am scaling my drawings for the jig from some pictures i got from the web unless some kind person has actual details I could use.I need to know what sort of hydraulic press power will be required as I will purchase one for the workshop.I am open to any tips from anyone with actual experience.I have a test rig were I can revolve the crank between centres to check phasing etc so hopefully I can get things right.Thanks.
 
Thanks Cosi.I am new to Laverdaforum so please excuse my ignorance.I am an Italian bike nut from my teenage years and I am 55 yrs old now,so you could say its an addiction.I am an automotive machinist by trade and I am one of those strange people that likes to do all my own engine work.I have come to really enjoy the Laverdas over the past few years,especially the triples.I have rebuilt ducatis,benelli's and 1 Moto Guzzi,but the Laverdas have become my favourites.I have three triples and am looking to purchase a fourth in the next few months,a 3CL.I am interested in rebuilding my own cranks and getting more of these great bikes back on the road,it surprises me just how many triples there are sitting in sheds not being used for one reason or another.Two of my triples are ex Aussie bikes and I have been known to attend some of your swap meets(Ballarat and Bendigo)and I have always found our Aussie neighbours to be very helpful, and customs have had a few surprises at some of the goodies I have managed to get back to NZ.If you are not bored rigid by now I would be very surprised!!Cheers Lynn.
 
Attention the owner of that rebuilt crankshaft on Laverdamania is a buddy

He sold his bike, and the new owner has had trouble with the crankshaft

A priori, it lacked a notion of alignment

I think it's need more information on the reassembly
 
Where are you in NZ Lynn ? Got your own business ?

If you're interested in doing roller cranks I can point several customers your way...

Of late years there's been a lack of the skills needed to do roller crank work in NZ, a lot of the race stuff is sent overseas to do.
I'd really like to find someone here who can do good work at affordable prices.

Thank you to everyone that has responded so far,it is good to be a part of such an active group.In answer to Greg I would possibly consider doing outside work once I have done a few of my own cranks and made sure they are working correctly.I only have a small workshop at home these days so it sometimes takes a wee while to get things done and this is after hours work.Thanks.By the way Greg do you know Pete Pastas?I was living on the Mainland up until very recent times,hope to move back in the next couple of years. Regards Lynn.
 
Yep, know Peter well. The 1200 in my avatar is the triple I built for him - as well as several other bikes.
He's talking about moving North so you may see him again sooner than you thought...

I may well see him at the weekend so I'll ask about you, LOL.

No relation with the rebuilt process, just the big end clearance was too tight.
