Hi Joe,
If I use the Eldo crank sprocket in place of the Convert one, the pulley
lines up perfectly. But, the hub then only contacts the crank taper
nearest the sprocket - the hole is already too large to machine the
taper in. The hub will surely spin on the crank unless I fix it in place
somehow. I could make an adapter sleeve with the i.d. tapered to fit
inside it. Just making another complete hub with the taper might be the
logical thing to do. Or better yet, since I have more money than time
right now, just buy the adapter ready made and move on to other things!

Thanks to everyone who responded to my questions.

Charlie,
I think you may be able to modify a loopframe crank pulley
hub to work on a tapered nose crankshaft. You would need to machine the
hole in the hub to match the taper. You could use a lathe & cut the
taper in the bore using a boring bar, or perhaps you could get a tapered

reamer to match the taper on the crank - I'd still use a lathe to hold
everything straight. Don't worry about the keyway-not needed.
The trick is to turn/ream the taper to the correct depth so
that your belt stays aligned. Or you could spend the $120 & be done with

it.

Good Luck!

I have a Cali 2 engine in my Eldo. I bought the crank adapter from Mark

at
Guzzi Classics. Worked like a dream. As for the gen bracket holes. I
marked the drill bit depth by measuring the old hole in the old block
with a
tooth pic. I tool a punch and marked the center of the bosses. Then
using
a variable speed drill, slowly drilled the holes until I reached the
depth
marked with a piece of tape wrapped around the drill bit. I then
installed
a set of studs with loctite rather than using bolts. I mounted the
bracket
using locknuts with nylon inserts. So far so good.

Subject: Convert engine into Ambo questions

 
 Several Loop Listers have done similar swaps and I need their input. I
intend to use the Ambo timing cover and generator instead of the stocker
cover and alternator. Here are my questions:

1. Did you use the Teo Lammers crank adapter from Moto International to
mount the pulley to the front of the crank? Is it of decent quality
reflecting the now $120 price? Eyeballed the situation this evening and
it looks like I could use an Eldo crank sprocket and stock pulley
adapter if I could figure out how to keep the pulley from spinning on
the tapered nose of the Convert crank. Some sort of chemical locker
maybe.

2. How did you drill the bolt holes in the top of the case for the
generator bracket - just eyeballed it, used a jig of some sort or? I'd
really like to get them straight!
