-------------------------------------------------------
Sequence as found in catalog. Engine displacement often not clear, thus not always included here.
There are some lines that appearto be exactly the same, their position on the list can tell you more,
that's how Bosch did it and i kept it like that.

* Strange but true, the 1200 was available with 1600 (1200S), as was the 1300 with 1200 40 Hp engine and vise versa. The 1303 (Super) 1200cc was meant for Italy where the road tax system is based on Hp or engine size.
! Bosch informs that their points # 1 237 013 119 can also be used, these have a Polyimid lifter for better wear resistance.
And yes, the Bosch catalog refers to 'Kombi' and 'Stationwagon'.
Bosch RPM limiting rotors:
1 234 332 144 >5400 RPM normally used in T4
engines
1 234 332 192 >4500 RPM normally used in 1600 Baywindows
1 234 332 314 >4800 RPM normally used in 1600 'Export'
Baywindows
1 234 332 207 >5800 RPM normally used in 4-cyl
914s
You can select one of the above to fit your stock (either T1 or T4) or 009 distributor. If you have a T4 in your '74 i'd recommend the >5400. This one is also good for the performance oriented Bus owner who has a better than stock rebuilt engine with CW crank. For a stock 1600 I'd use the >4800 or a >5000 from another car, Saab maybe. If someone needs a more specific RPM limiting rotor contact me privately and I can sort thing out for you.
If you have one of these in good condition the limit is printed or stamped on the rotor. These rotors limit as follows: on top of the rotor is a springloaded switch. This switch is operated by centrifugal force. When the force on the switch is high enough overcome the spring pressure it will close the contact and the rotor is shorted to ground until the spring takes over again and ignition is restored. Actually, I think that the spark will jump to ground before the switches physically closes, so it's hard to say how accurate the rotors are without testing them on a distributor test bench. But i don't think a revolution more or less will really hurt :)
"I have a 009 with both vacuum and centrifugal advance. The Bosch part number is 0 231 174 009; the VW part number is 039 905 205; it has the marking JFUDX 4 on it."
0 231 defines it as a distributor (although 0 237 is also a distributor and there might be more numbers). 174 009 is the actual Bosch part number. 039 tells what type of VW or VW engine this part is for (in this case a 039 engine). 905 means ignition. 205 is a distributor. You'll find the same 905 & 205 on a EV distributor. If there are more distributors starting with 039 the part number will be followed by code letter(s). I haven't found out what all the letters in JFUDX mean, but the U stands for Unterdrueck (vacuum) and the F for Fliekraft (centrifugal force) the letters will also tell if the distributor has the dual points for the FI system,
There are several distributors of which the part number end with 009.
I have a 0 231 178 009. It's a mechanical advance VW aftermarket distributor. On the underside it has a cast-on boss which states "Germany" on the German made ones. Mine is Brazilian made and the word Germany is not on it.
The 0 231 174 009 was used on 08.72>06.73 2.0 914s both on Euro and US models. I don't have more on it, my data goes back to about '70.
I don't have the advance curve data for it, but I do have that info for the VJR 4 BR 1 through 35 and the original Bosch advance curve graphs of the: 0 231 176 040, 0 231 178 005, 0 231 176 046, 0 231 178 006, 0 231 178 002, 0 231 178 007, 0 231 179 001, 0 231 156 001, 0 231 168 003, 0 231 164 002, 0 231 168 001, 0 231 170 068, 0 231 170 069, 0 231 168 001, 0 231 164 004, [these all aren't necessarily VW dizzies]
AND our beloved 0 231 178 009 JF4
The flat spot of the 0 231 178 009 starts @ 550 RPM =/- 50 RPM (distributor) and ends @ 975 RPM +/- 25 RPM. It can give 9 to 12 degrees of total advance @ 1275 RPM. The point gap should be 0.45mm and the dwell 47 deg. +/- 3 deg.
I would use a rev limiting rotor on any Bus and the Bosch 193 distributor cap which has a clearcoat on both the inside and the outside. The cheaper 056 which is usually sold only has a clearcoat on the inside. On high RPM engine I would use the Bosch 145 points. These have a heavier spring, nickel plated contacts and a poliymid lifter which is more wear resistant than the standard resitex material.
"The top of the distributor shaft appears to have been machined to taper it slightly. I'm wondering if this was normal or if some bozo did this to put on a rotor that really didn't belong on this distributor. I know the rotor from a fully centrifugal 009 won't fit; its base diameter is too great."
There should only be a rounded shoulder. i have the 207 5800rpm rev limiter of a 914 in my 009, and it fits properly.
