Visual Comparison of Typical Tune Up Parts

[Frederik]

I'm using the long Bosch spare part number and not the short Exp. number/ new numbers for the rotors. The late ones are included:

04004 = 1 234 332 074 = ZVVT 5 Z 6 Z= VW 181 905 225
04012 = 1 234 332 107 = ZVVT 9 Z 1 Z= VW 113 905 225E
04033 = 1 234 332 215 = VW 043 905 225 (et al.)

The look of the 04012 shaft (and the other that looks the same) was due to dust cover design. I also guess that's why my 1980 Bosch chart list the 04004 (074) as replacement for cars that had the 04012 (107) as it's thin shaft should fit down dust covers that previously needed the old design.

You see the same change in design on the rev limited rotors.

If you have the large diameter center hole dust cover or no dust cover at all you should be able to use any of this rotors in place of one of another.

Thanks for the clarification of the long/short Bosch numbers, but since there were some other non-Bosch components compared in some of the examples, I was looking for some Bosch alternatives. A lot has changed in the automotive parts world since your 1980 chart, and even from Feb 2010 when this thread was started.

I don't have any components in front of me at the moment for pics, but I have used Bremi 12111360305 rotors, and I have talked with shops substituting Volvo Bosch 04038 rotors for Bosch 04033 ones. The 04038's have a wider contact tip, and about double the resistance of the 04033.

Bremi 12111363423, and Beru VK106 caps are almost identical to Bosch's 03010.

Bremi 12111267393 points are a nice option to Bosch's 01011, but I haven't found a Beru/Bremi, or other replacements for the 01030. I tried a set of Standard's GB-4173XP points as an alternative to a set of Bosch 01030's, and yes, they have an excellent spring that more than likely can hold up a car. The Standard points too seem to be in dwindling supply.

The wide tip "300" rotor with rpm limited brother. Used on vanagon and many other late 70-> cars including some type1.

Late "tall cap". 1 235 522 056 = 03010
The "183" and dowal cap looks almost black in the picture, but they are the nice dark brown bakelite. The Bremi cap looks larger diameter in the picture but it's an illusion in reallity it's the same diameter.

Cross referense list of caps and rotors. I've narrowed it down to Bosch, Beru and Bremi as they are good OEM brands. Bosch parts are getting harder to find, some parts are NLA and expensive, but the equalent Beru parts are for most parts available, decsent priced and good quality made in Germany. Armed with the Bosch, Beru or Bremi part # it's also easy to find other brands cross referense parts.

Cap Bosch 1 235 522..

.."107" (03019) - Beru VK101 (VK154) - Bremi 8016 [1]

.."144" (04016) - Beru EVL065 - Bremi 9054 [6*]

[1] For "36hp" cast iron distributors. [1*] "070" rotor is usually listed for Porsche (356/912) and by porsche parts list the "072" (presuccessor to "088") is for dust protected distributor and "070" non dust protected, but it works as good in vw. The differens is the use of dust cap or not. See previos posts about difference of rotor and fitment with dust cap.
[2] For "Big cap" case iron distributors (early 60s)
[3] For "short cap" distributor (most mid 60s distributors)
[4] For "one year only" 1964 type 3 1500s
[5] For "tall cap" late 60s-> aluminum distributors. [5*] Usually are listed for the earlier distributors and [5] for the mid 70s, but they should be interchangeable.
[6] "Rew limeted rotors" mainly used for type 2, interchangeable whenever a [5] is used. [6] are 4500RPM limeted, used in 1600 and [6*] 5400RPM, used in type4.

For more exact fitment it's better to use the "Bosch Tune-up" chart under technical.

Visual comparison of caps (late tall caps)

From left to right Beru VK106, Bosch 1235522056, Bremi 9045

All 3 are availible, but the Bosch cap are getting a bit pricey. The Beru cap is a nice part. Marked with part numer at the side, "made in germany" in the casting on the inside top, same style carbon brush as Bosch, painted inside (more on this next). All have copper contacts, but the Beru is molded to the sides.

Next Bosch 1235522193, Beru VK321

The "193" (as it's dark Brown presuccessor "183") are NLA but can be found NOS. The Beru VK321 however is availible. The Bosch "193"/ Beru VK321 have painted (clear) inside AND outside. Can be seen as it's more "glossy". The carbon brush in the Bosch has been replaced, and are non Bosch (thats why it's different).

Visual comparison of caps (36hp)

From left to right Bosch 1235522107, Bremi 8016, Beru VK154, Facet 2.7462

The Bosch "107" are NLA, there are however replacement orange caps and maybe it would have been more correct to include them for comparison but I don't bother with them as I think a orange cap on a cast iron distributor spoils it big time. The Bremi 8016 cap is a nice replacement, however I don't know if it's on it's way to be discontinued as it's out of stock from some of my suppliers, it would be my #1 choice if I run out of NOS "107" caps so I hope not. The Beru cap is the VK154 and it's a polyester, painted inside cap as the previos late caps and puke orange. There is also the VK101 availible and it's phenolic, but probably orange so I don't bother about it.. I also included a non OEM brand cap, Facet 2.7462. I got a small batch of old stock ones and they have a nice Brown color. They are not as nice made as the Bosch, and have aluminum contacts, but they work great, looks good and I have used them as "daily drivers" with no problem. I've included it as they are still availible, I've have no idea if the new ones have the same color or not.

I won't show the rest of the 60s caps as I only have NOS caps of diffenent brands and don't buy new ones for the same reason as above: the dark Brown ones looks a lot better and are still easy to find and often cost the same or less than new ones. For me a vintage Vw is all about the looks, if it wasn't you could as well throw in a 1600, type4, Subaru or whatever.. might even buy a new Beetle. I'm no purist, my cars are far from original, stock or good looking, but it has to look somewhat period correct to do it for me.

I will however get back to the rotors..

Rotors Visual comparison Bosch vs Beru

"070" vs EVL027

"074" vs EVL4/6-O

"215" vs EVL029

"088" vs EVL4/6-Z

"107" vs EVL030

Were the Bosch was nice brown phenolic so is the Beru

Added the Bosch 1234332107/ Beru EVL030 visual comparison of rotors.
Not the best comparison as the Bosch one is worn out..

..and added the rew limeted rotors in the cross reference list

[Frederik]

So now when I posted some new parts maybe I'm forgiven for posting old Bosch parts again?

Caps

(The flat top is not a Bosch in the picture but a Bremi)

[Frederik]

So out of curiosity I ordered a Beru vk101 cap ("36hp" cap) and I must say that I'm surprised, in a good way. Quality is really good!

-Comes in a nice branded box, marked "made in germany"
-Beru, germany and partnumber printed on the side of the cap
-Nice dark brown phenolic, almost "correct" although not as dark as the original Bosch, but none of the new ones are. (I was wrong thinking this cap would be orange).
-Copper wire connections and contacts.
-Good quality carbon brush, "Bosch" style with a profiled tip
-Sanded flat edge

This cap is a good No1 choise for daily drivning and a substitute for NOS Bosch caps. Overall apperence is a noth better than the Bremi cap. And the price is good also at just above 10€.

[tasb]

The early 1950's caps made by Bosch did not have their logo on the outside ofthem so these look even more correct.

Hi will a 383 cap and rotor fit/work on a 019 distributor???

[tasb]

Better late than never...

The rotor shaft on an 019 is thinner so the 383 rotor is too loose. The 019 shaft is too tall there's not enough room for a rotor AND a cap. Otherwise the cap does fit.

short answer= np.

If one had a good supply of vintage caps and rotors fir all makes it might be worth a try to test different rotors and you might find one that would fit AND work.

Bosch spark plugs chronology

Box fom left to right:

* 50s spark plug. Also plug to the left. Smooth insulator, no Bosch printing on the insulator besides two green stripes, back metal base with Bosch printing.

*Up to mid 60's spark plug. More colorful printing, "thermo-elastic", no bosch "rivet" logo and some small design changes in the print. Looks like 2nd spark plug. Smooth insulator, "Bosch" print om insulator, silver metallic base.

*Mid-late 60's spark plug. Whole new design layout on the box. The plug still looks like the 2nd with smooth insulator.

*late 60s-early 70s spark plug. Plug now have a ribbed insulator. Note that the spark plug on the print now also is ribbed (the smooth insulator plugs had a smooth plug on the print). Looks like the 3rd plug.

*70s spark plug. Spark plug in the print now tilts to the other side. Looks like 3rd spark plug

*Late 70s spark plug. Cr-electrode print in black, more sketchy print of the plug and some smaller design changes. Still looks like the 3rd plug.

*80s spark plug. Late 70s the Cu electrode core plug came, called Super in green print om the box. Looks like 4th plug.

*And to the right a "modern" box, have been some different. This is from 1999.
