25hp generator removal

[dave1]

Hi all,
Can a generator be removed from a 25hp split beetle without removing the engine? Can only find info on later engines
Thanks in advance
Dave

Yes, it can. Remove engine lid and it's hinge supports under rear window. Then fan shrould with generator can be removed.

Can it not be removed without removing the decklid? Same like with later Beetles by removing the big nut of the fan so that it stays put while sliding the motor out?

[virtanen]

Sure you can, but I remove lid to get all assembled back well.

This is the process in the '61-'65 Bentley manual. The fan shroud got much larger in '63 so given the smaller size of the 25/36hp shroud, you have much more room to lift of the shroud.

1. Disconnect cables from regulator

2. Remove carburetor

3. Take off fan belt.

4. Disconnect generator mounting strap.

5. Remove throttle ring and the screws on both sides of fan housing.

6. Remove four screws on fan cover and take of generator and fan.


If I remember correctly, I used this method on my first bug, a '65 with fresh air fan shroud which is much larger. Didn't remove the deck lid. The only time I ever removed the deck lid and hinges was to replace oil cooler seals, where the shroud had to come off completely.

Isn't the oil cooler preventing the fan shroud to come off then?

I did that job a month ago and found the easiest way is to unscrew the fan big nut of 36mm in the back, loosen the fan shroud and lift it a bit after removing the carb and ignition tube. You can also remove the throttle ring but it's not really mandatory, just loosen it up and undo the spring. After removing the four bolts of the backing plate and mounting strap, you can lift it over the generator stand.

Either take the engine out or remove the engine lid. Either way then you can take apart and assemble all the gen/fan parts properly in your sight.

Taking the fan/gen apart with engine in or lid in place means you have to take it all apart with many parts out of sight. So too easy to drop spacers down into the shroud around the cylinders, which then will require engine removal anyway.

Then assembling all those parts out of sight where you can off center shims or drop them again or crush/damage them due to being off center.

The easiest way and the fastest way have been said to just drop the motor; it only takes 20 minutes. I find it better then dealing with the decklid alignment and that fun big spring.
