You can take the alternator out without disturbing the carbs or shroud. You should be able to pull the alternator and fan without removing anything other than maybe the crossbar linkage, but only if it's in the way.

4 screws to remove alternator/fan assembly. Really not a big deal.

I've recently taken my old one out and put in an expensive high amp Chinese alternator. It was bad from the get go and I ended up removing that and putting in a new Bosh 55 amp alternator and all is well.

I have a Raby motor and DTM fan shroud. To remove mine I disconnect the 1-2 carb heim joint/s, remove it's top air cleaner and base (which releases the throttle linkage bar) remove the linkage bar. Caution: My linkage bar has a spring inside of each end to allow for movement (If you have the same be careful when removing or they may spring out). I then loosen the Fan nut, take off the pulley, then I have to remove the alternator stand. Then I take the fan off and pull out the alternator with it's mounting plate after removing the 4 mounting plate bolts from the shroud. It's tight and it requires a juggling act to get the alternator and mounting plate out but can be done rather easily. Install is the reverse.

Yours may be much easier if you don't have a DTM shroud.

Fernando, since you have a stock fan shroud, unbolt the brackets that hold the cross bar, remove the 4 bolts holding the alternator tin to the fan shroud, remove the band that goes around the alternator and it's base. pull the alternator away from the fan shroud.

Some will also recommend removing the fan from the alternator shaft (36mm nut) before trying to pull the alternator away from the fan shroud. Don't drop the 36mm nut or the wavy washer behind it during the process of removing / reinstalling the fan.
Also, surf YouTube for videos of the process. It is a simple one, and maybe even easier on a spyder than a beetle.

Don't forget to disconnect the negative terminal from your battery before picking up any tool. The big wire on top of the alternator is a sparky one!
