US VW’s had 6 Volt systems up the 1966 model year. it’s desirable to convert cars to a 12 Volt system to brighter lighting, better or in order to add modern sound Of course, if originality is a concern, you want to keep the old 6 Volt working.

This article into what’s needed for the and pitfalls to watch out for.

The starter motor is problem. You can’t just in a 12V starter.

Here’s the reason:

the advent of the 12 Volt system in VW changed the number of teeth on the from 109 to 130. This the flywheel bigger in diameter (by .160). That meant the pinion gear on the starter, also meant reducing the of the starter pinion shaft, meant changing the pinion bushing in the bellhousing! They reduced the bore in the bellhousing for the The pinion shaft was reduced .491 to .432 and the bore in the went from .652 to (These numbers are approximate; use them for machining stock.)

folks leave the 6V starter in and run it on 12V. It will survive for a surprisingly long time if you the duration of cranking short. You can the solenoid on the starter for a 12V unit, if That will lower the drawn by the solenoid.

In most situations, if you’re the original 1200/1300 engine, the old 6 Volt starter is the best way to go.

If putting a later 1600 (or engine in, you must either on a 6 Volt flywheel or change to a 12 starter.

If you do decide to use a 12V starter, you to use the 12V version of the flywheel and machine out the bellhousing for the larger diameter.

The 6 Volt flywheel will fit on the crank but the later 12 Volt won’t fit the earlier 1200 Be sure to check the crank if you swap flywheels.

If you do change the starter, you must change the pinion bushing in the

With the engine out, easy to tap the old bushing out from the side. Special replacement are available to use a 12V starter on an old 6V bellhousing and to be able to use a 6V starter on a newer 12V Be sure to get the correct one.

If to a 12 Volt starter, try to find one an auto-stick car. These use a bushing in the bellhousing. These are also more powerful.

and pressure plates:

This issue isn’t related to a 12 Volt conversion but it pops up. Beginning with the models, the throw-out bearing was re-designed. On earlier cars swing-axle and IRS), the throw-out was held onto the shaft 2 U-shaped clips and the bearing was to pivot on its stubby pins.

The new is more firmly anchored by new and is supported by a guide sleeve runs through the center of the

The bearing now has a wide thrust built into it. This the need for the thrust ring on the plate.

If you try to mix the new bearing with the old plate or vice versa, it work and you’ll have adjusting the cable or may damage the or release shaft.

Pressure for use with late-style throw-out

So, if you’re installing a later engine into an early you may have to replace the pressure with an early one which has the ring.
