The myth of the 1967 "only" generator.

People often see a generator with the rectangular terminal connector block and push on terminals and presume it is a 1967 "only" thing. Well, it is not. For whatever reason, Bosch made both 6 volt and 12 volt generators with this style terminal block.


EDIT: a 507 (July 1965) generator has been seen in the classifieds. See this post:
https://www.thesamba.com/vw/forum/viewtopic.php?p=8847990#8847990


The earliest I've seen is a GR-14X, 7V 45amp with a 509 (September 1965) date code, VW part number 131 903 021, Bosch part number 0 101 302 061. Production of the 6V type went into 12v-era cars, as I've noted 6V generators with date codes as late as 11/1966.

On the opposite end of the spectrum, the latest I've seen is a 12 volt with a 802 (February 1968) date code, which is well into 1968 model year, VW part number 211 903 031 or 031A, Bosch part number 0 101 302 067 or 075.

As far as I know, these are all late style 105mm diameter generators, standard length, not requiring different backing plates, hubs, or special pulleys.

There is also evidence that this style was used on Type 3's as well, although I've only seen a few of them.

Please post any other date codes or types of this generator. Do you have one that is earlier or later than the dates posted here? Let's see 'em!

Here's a poor photo of my generator marked 802. It is however a genuine Bosch generator made in Australia for my Dad's owned since new 1968 1500 Beetle. It has the push in terminals and plastic connector as described by the original poster.

Both the generator and starter motor were "Made in Australia" genuine Bosch parts.

Thanks for doing your homework, this could be your doctoral dissertation. I think that, as with most of the auto industry, many of these types of items are used and phased into the public as the industry sees fit to do so. Many different companies, including Bosch, manufacture items at different times and places and utilize them as they see the need. The change in design of a generator is probably based on both experimenting with the design and also the outcome and feedback given from performance and/or need of the unit. Obviously the push in plug did not make it permanently as somebody in Bosch decided it was not in the benefit of either the public or the repair man to utilize this type of design in future generators. Maybe it cost them too much to do this design and we are stuck with the clip type. Kinda like evolution weeds out what does not work in the long run. We have to take the idea that this is only for 67 with a grain of salt in that it obviously was used over several years and in several different applications. However, the number of generators that Bosch produced during the 1967 year was predominately this type as compared to other years. Unfortunately it was deemed not to be produced later on by Bosch for some evolutionary reason.

Found the following dates from generators I have in storage:

6-volt ones: 6/11, 6/6, 6/10.

12-volt ones: 6/10, 7/11, 7/7, 7/9, 8/11, 9/8.

All have the typical 67 push on connector.

Found one with the date of 910. That makes it about 3 years of manufacturing this type of connector that was only supposed to be on the 67's.

I've seen some VW factory manuals that show the plug in style generators in Ghia's and buses as well. Most people believe this generator was in 67 bugs only. The pictures I've seen included ancillary items on the engine that showed it was in a bus or Ghia.

Here's a picture out of a 68' bay bus owners manual. Now, we all know VW reused many pictures from different years or models in owners manuals as well.

Edit to the first post:
This generator appeared in the classifieds. It has a 507 date code, July 965. It predates the one in the original post by several months.

The seller said this in an email, regarding the date code:
I thought this was a spare generator but in fact this is the stock generator from my '66 13 window deluxe (I updated my ad). My bus is stamped August '65.

Saw this generator at a swap meet. Sorry that the stampings are difficult to read.
606 date code, June 1966.
14V 30A
0 101 302 067
VW part number 211 903 031

This shows that Bosch was already making 12V generators in this style prior to and/or in preparation for 12V systems being stock in VW vehicles.
