Engine alignment

David,

When I designed and made the aluminum alignment tool in the photo below, I found it was too tight a fit as the input

shaft which is also 35.00 mm. To make life simpler open the hole up a few thousands of an inch. Above is the tool used by Amel . The bolt  holes are not necessary and I just simplified their design.

David,

 

Some mechanics have aligned without a special alignment tool (a fixed coupling) designed and made by Amel and easily duplicated in a machine shop. I think perfect alignment without a fixed coupling is 99% luck rather than skill. The alignment is done with the tool, then the engine is slid forward and the tool replaced with a Vetus Coupling. 

 

When the Vetus Coupling is removed, be sure to check the Rubber Bushings inside (sold separately). This is a drawing of that tool for a Super Maramu. Be sure to check the shaft size on your Santorin:

Hello all,

We are in Gaeta Italy where mechanics are trying to alleviate a mild but distinct engine vibration noted under load.  I'd rather not go into how this occurred but suffice it to say that moving a boat a few hundred meters at idle to a travel lift minus the stb forward alternator bracket in place is not a good idea.  (bracket was being welded after breaking and landing alt on spinning spline pulley)

 Our well intentioned but seemingly flummoxed non English speaking mechanics have us decoupled ( engine/transmission, not marriage) and best I can tell are ruminating on a fix.  I absolutely don't want to make matters worse.  

Any advice on what to do or advise them or what specifically NOT to do at this point would be greatly appreciated.  i think finding someone with significant Amel experience nearby is highly unlikely. 

Thanks so much for any advisement. 

Best regards,
