I'm not aware of anyone selling the correct springs. Do you have a good swap meet you can visit to pick up an old dirty distributor core? With a good cleaning, those springs might be as good as you can get. There's no telling how the weights of an aftermarket spring might compare to the Bosch original. Glenn or tasb will know for certain if you could buy a spring, but I always prefer dirty parts made in West Germany to anything made new.

The 059 998 211 comes up as a distributor shim kit, with no springs.

Maybe post the vw and bosch numbers off the distributor?
I could only find pictures of a return spring.

Those are NOT distributor return springs... they are HUGE.

Hey man! Glad your thread popped back up, I saw it a while back and forgot about it.. I's just gonna say,

you were so close... soooo close.. Next time you do one, grab an arbor plate off the press and use it to rest the drive tang on, to keep the shaft from spinning when you knock the pin loose.
also.. you can use a bench vise to press the pin back in place. Once the pin is seated as far as you can go with the vise, put a BB or ball bearing between the vise jaw and the pin to push it in all the way.

That's funny. I don't know what the heck that spring fits.

Yeah, a few pages back. The distributor drive gear play was obtuse, AND I didn't have the spring installed correctly. I smashed the spring down so hard by hand that it got caught compressed in the drive gear. The distributor is rocking in Hambone's second pastel white '69 Westy at the moment.

I missed seeing where you had found the issue. I'm putting together a Bosch version of the 205Q for my own bus - did the vac can have anything to do with your timing problem or was it all mechanically related?

My issue was purely mechanical, though my vacuum can pictured ruptured in about a week of hard driving. The used one I put on is still going strong.
And you didn't miss it; I can't find it either! During this thread I got tired of a lot of BS info on this site and I moved my technical questions over to the IAC forums.

No doubt about that bro!
Did you ever replace the dist drive gear? I've been unhappily watching my timing scatter with my 205T SVA - never thought about that spring being part of it like Amskeptic mentioned over there. Good info.

As I built up my current engine mocked up the assembly over and over, it became painfully obvious how important drive pinion to gear mesh is. Unfortunately, it can only be set perfect with the case split. Now, you could fully seat the drive pinion, measure it with a depth micrometer, then measure your distributor bottom-to-clamp distance. I err on the small end of the tolerance, because the magnesium case buttress that holds the pinion will wear over time. The drive pinion itself is made of significantly harder metal, so it won't wear fast enough for anybody on planet earth to work about.
The old engine got wonky on me around the time that I fixed this issue, and I realized on teardown that I had been driving for months with a dropped intake valve seat. (Note: throw those damn aftermarket cylinder tins away.) So I never got a chance to run this distributor on a perfect dual port after the first month I drove with it before the problem showed up. But damn, it drives sooooo smooth!
Does your timing scatter at idle, speed, or both? Vertical play in the distributor shaft combined with a loose drive pinion tolerance can cause a small version of what I found on the old engine. A radially worn bushing or two in the distributor shaft will absolutely cause scatter as well. If the radial play is perceptible, I won't use the core for a rebuild. Cores are cheap right now, so I have a box of 205Ts for the future when they're scarce…
The funny thing is, these are all problems that electronic points replacement zealots tote around as being fixable by the modules. Nope, just bad advertisement lies; fix 'yer cars.

timing scatter is often
1. a bad gun or inductive pickup. Sometimes reversing the direction of the pickup helps.
2. wobble in the shaft - usually shows up as fluctuations in dwell too
3. bad or worn points. Sometimes the pivot can be sticky and the spring not strong enough to bring them back so they float.
4. If electronic ignition the magnets or optical wheel can be loose.
On a VW it can also be a loose, damaged, or missing spring between the drive gear and distributor as you found out. Basically anything that allows the points or electronic ignition to fire at slightly different times - or delays in the timing light due to electronic failure there.

What kind of tool do you guys like for pushing the split snap ring onto the shaft?  |
Find an old writing pen with a metal body. Unscrew it (remove the inside), and use half of the body as your tool. The diameter of the body should be just slightly larger than that of the snap ring. Use a dab of grease to hold the snap ring in place on the open end of your tool, then tap it on to the shaft with a small hammer.
I used this method and it worked perfectly.

Robbie stopped by my place a few weeks ago when he picked up the bug for his buddy. He saw this NOS Bosch 853 vacuum can and suggested I post some pictures of it since it's missing the dimple in it that was so heavily talked about in this thread.
It's marked 853 on the arm.
This distributor which is very close the 205Q in curve had this non-dimpled, 853 can on it. I bought it to rebuilt it and try in my bus. I'm currently running a bug DVDA 043C in it which works nice. I'm just curious to know the difference in drivability between these two distributors.
It appears that the can pull range is adjustable on it? Anyone know for sure?

Can you get a good pic of the other side of the adjustment screw. Inside the dist. where it would contact the actuating arm?
Thanks
Tcash
Or better yet, pull the vacuum can and takes some pix. |

Here's the further pictures. I'm not sure how much that adjustment would effect anything? It looks like the pull arm hits the can and the peg before the adjustment would have any effect? Maybe what I'm viewing as an adjustment is how they assembled it?

Maybe thru some error the can brackets were originally made without the stop, and they did that instead of chucking the lot?
