Looks to be a rather inventive home repair. Makes me wonder if it gives the correct advance using that scrap of interior vinyl for a diaphragm.

Here are a couple of oddball vacuum canisters that need to be included in this thread. The first is used with the 1959 Ghia only from August 1959 until January 1960.

There are plenty of fittings out there with partial lines on them. I think WW sellls a repop line for $25?

My Robert Bosch catalog from 1976 lists more than 30 different vacuum cans for VW. most of the cans do not have a readily identifiable part number. When I first started rebuilding distributors about 175 ago, I used whatever can came with the distributor. I did not realize how easily and how frequently the cans were changed out (sorry  ). This is surprising because most vacuum cans are still good. the moving parts like the advance plate dry out and freeze up more often than the can fails.
The first vacuum can that I will cover is the common one used on 36 horse power engines. It has a unique shape compared to later VW cans. It has a threaded vacuum port and a large nut which is really a cover. The cover hides and adjustment screw that is set at the factory but made accessable for adjustment later. I have not played with this adjustment much. Part # 113
There is a date stamp on the mounting base that gives you a clue to its manufacture. It is the tyypical number and letter stamping used by Bosch. The code can be interpreted using data available elsewhere on this site. Many of these vac cans have dried out after so many years. |
What is the thread of the vacuum port on these cans? I picked one of these distributors up and wanted to make up a fitting for it without having to mangle an original metal line...

Nobody attempted an answer: the pull rod on the vacuum canister was installed upside down at the Bosch facotry. Odd that it passed inspection but it works just fine the way it is.

here's an oddball vacuum canister. It's a Big Cap 40 hp canister. I've got about 100 of them. besides the nipple for the vacuum hose being located at 9:30 on this one can you spot the inconsistency?

Here is a batch of NOS vacuum lines for the vacuum only distributors. The part number is 211 129 497. They are steel with a coating of copper.

I too am having a hard time finding vacuum canisters for the 113 905 205 K. Not because the canisters have gone bad as much as the canisters are dented or just plain hard to come by being one year only albeit there were a lot of 1966 beetles and buses running around once upon a time.

I have 7 that are useless... 2 were brand new.. LOL
They either leak or they are too stiff and notchy.
I give up on looking and have spent $100 buying cans that people "tell" me are working fine.
So, it's the 68-70 can for me and static TDC timing. Seems to run great.
I'm out!

Well out of the 5 I received today only one is close to being okay to use...
They are all stiff and sticky.
6-7 bad out of 8.

Wow.. You're lucky to have found that 7.5BTDC NOS vacuum can! I guess I need to look a bit harder. TASB says the vast majority of these vacuum cans on these vacuum only distributors are still good on the distributors he has rebuilt. The "star" 67 vacuum can on my 67 bug is original and has no issues. I bought several used 205 "T" vacuum cans with some core distributors. All of these used "T" vacuum cans failed to hold vacuum! So, I have no spare "T" cans right now.
I did get lucky and bought several used distributors a guy was selling for $4 bucks each at the last VW swap meet I went to. I found a 205M distributor with the "star" vacuum can. It looked filthy on the outside. When I took it apart, I was shocked how clean it was inside and it showed very little wear. The fiber washers were perfect as well. I cleaned and lubed the internals. It cleaned up beautifully and the can was dent free and holds vacuum. By far, my best swap meet find I've scored. It's now my back up distributor for my 67 bug.

And to muddy the waters, the star pattern also appears on the 40 hp vacuum canisters. You can instantly tell them from the later 113 K vacuum canisters because the 40 hp big cap canisters have three mounting locations where the later have only two.
The correct canisters were still available back in the day at the dealership (as above without the star pattern). The customer or the service technician needed to know the difference though and often they did not.
I would say 1 out of 20 distributor cores that I receive have the incorrect vacuum canister installed.

It's perfectly fine. Back in the day, when the original "star" 7.5 BTDC can blew out, you'd of replaced it with that 0 timing can you have now. The most important thing is to time it to the vacuum can, not the distributor. In many years on this site, I've never seen an NOS 67 distributor "star" vacuum can for sale. You can still find the 205T distributor vacuum cans NOS though they are getting pricy.
I wonder how many VW's out there are not running as well as they should due to someone reading the distributor number and setting the timing to it vs. the vacuum can that is mounted on it.
You can also measure the travel of the vacuum can arm to verify which can it is if it doesn't have the "star" pattern on the vacuum can. I did to compare the "star" 67 distributor can vs. the 1969 205 T vacuum can set at 0. There was a difference that this thread highlights.
