electrical and ignition Sources For Rebuilding Distributor Vacuum Units

[RAS-2002]

I found someone that rebuilds the vacuum units on Bosch dizzies: British Vacuum Unit in NH.

While Rob does mostly British car vacuum units (i.e. Lucas), he also does Bosch.  I sent him the leaking vacuum unit from my Bosch dizzy and was pleased with the result.

 

Also, Advanced Distributors says on their site that they rebuild vacuum units, although I haven't tried them out:  (if anyone has used them for rebuilding vacuum units, please let us know)

i sent a Bosch vac advanced distributer to Advanced Distributors and received it back, rebuilt but with a note that the vacuum gizmo was inoperable.  there was no mention or suggestion from them that it was fixable.  i subsequently found a good vacuum gizmo in my stash and swapped it out onto my newly rebuilt distributor.  Unfortunately, i am currently running with the vac advance plugged as i was told by a knowledgeable 02 mechanic (JP, A1-Autowerks) that i had too much advance on my rebuilt distributor with the vac unit.  so what i have, i suppose is a vac advance distributor working solely as a mech advance distributor.  i'm a little bummed after shelling out $250 for the rebuild.  i will add, though, that the timing ball is indeed steady under timing light now.

Advance Distributors rebuilt my dizzy a couple of years ago with an advance curve customized for my engine setup (284 Schrick, 9.5 pistons, downdraft Weber).  They deliberately disconnected the vacuum advance as part of the recurving.  Left it on the dizzy to (1) plug the hole and (2) maintain the stock appearance. 

 

Runs beautifully--no bogging, nice smooth idle; what's not to like. 

 

Nice to know a source for rebuilding vacuum advance capsules, though.  My '69 still runs one.  And they're NLA from Bosch. 

 

Just a thought, though...aircooled VW Beetles use a dizzy that's very similar to a 2002's--same cap and rotor, and on some the same points and condenser.  Wonder if the vacuum advance units interchange, and if they're available through a VW parts specialist....anyone know?

VW vac adv  has different part numbers .

Ahh, the vacuum gizmo.  They are non- adjustable, consumable, and ALL DIFFERENT!   Oh, and they changed on about a yearly 

basis, so don't get too excited that almost none are available any more.

 

Instead, get rid of the distributor entirely and use MegaJolt!

 

Or, dig around in the VW parts bins and see what you can find.  The variables seem to be travel

(which can often be extended)

and spring pressure, which is usually unadjustable.

 

It's been a bit of a challenge for me since 1997...
