Outer Limits 4x4 Board

G'day all,

Just wondering if any one has an exploded view of the 1.3 dizzy that they are willing to share, or any pics of it apart. In particular regarding the sensors (which im assuming are hall-effect) and mechanical advance mechanism. Even at least a pic of it without the cap on will help a bit.

Cheers
Dan

Looks very much like a VR setup to me... would be typical for a Japanese vehicle of that age.

Much better than points but very average when it comes to discharge energy.

Don't go swapping coils either - the modules have little safety margin, which when stock is absolutely not a problem.

Thanks for that exploded view want33's.

MightMouse are you 100% sure that it is a VR setup? Or can anyone confirm what type it is? (Hall or VR)

Cheers Dan

Ive been emailing Sarge and he says it could be hall personaly I know nothing about it so Im watching this thread.
Nik

Look at the reluctor - its appears to be the wrong shape for a hall, and whilst its damm hard to see from the drawing the bias magnet appears to be on the outside like the pickup - identical to many single tooth VR systems

Hall have a windowed style chopper, with the sensor on the outside and a bias magnet on the inside ( usually )

The module also appears to be a ND module common to that period.

Still its only an opinion based on a hard to see sketch - not firsthand viewing - and of course there may have been variants just to make life fun....

As as an aside why the interest - programmable ignition ?

These arnt zook bits but you can see the difference...

VR




HALL

I'm just not sure what your countrie's market was offered , here we only had 2 versions . Early mechanical disty's used a standard electronic reluctor pickup , similar to Chrysler . Later efi engines used a full electronic disty controlled by the efi's electronic module .

My emails with Nik are concerning early version mechanicals , if they are not working at full potential it causes a lot of headaches with the Weber carbs .

So, what were the breakoff points and years over there for mechanical vs. electronic??
Sarge

Same pic.. This is as big and clear as I can get it.

I have an old Dizzy at home at the moment, if i get time over the weekend i will check what sensor it runs, and snap some pics of it stripped down and post them on monday.

Layto....

Thanks for the pic mate, does seem like a VR. Yea programmable ignition is a goer, just trying to work out my pickup source as my program is based on a locked TDC pulse and I want to try and get away from adding any extra sensors, so if the systems craps itself I can still limp home on TDC timing.

lay80n:

IF you do have that dizzy and could get any pics of it semi apart that would be great.

Unfortunatly im overseas atm (philippines) and am lacking any zuks to look over.

Cheers Dan

The "blow up" shows a VR pickup.

Of course if there are variants then it proves nothing. You really need to look in YOUR distributor to be certain.

As there are only eight cheap components in the VR pickup CCT for the programmable ignition system - getting it wrong is no big deal.

The exploded pic looks the same as whats in mine.
Nik

Ok, that drawing is the same disty as the early carbureted versions here in the States .... easy enough to rebuild if you can get main shaft bushings . Side wear is a problem with them since it changes reluctor gap and breaks up the spark at high revs .
Sarge

Good I might have a crack at it then
Nik

I pulled my dizzy apart and cleaned it up. The advance plate was a bit notchy so I regreased it and Ive checked the diaphragm on the vacuum advance and it dosnt hold vacuum.
Can this be sourced seperately? Anything else to fix/upgrade while Im this far in?
Nik

You may be able to source the advance from the dealer, or a vendor like Suzisport . Over here they are a bit hard to obtain .
Check the weight springs and weights in the bottom for sticking and clean up the posts while you're at it .
Unless you want to dive into re-curve on the timing , that's about all .
Sarge

Nik, I rang Suzuki about just the vacuum advance bit about 12 months ago and they wanted $90. Ended up buying a complete dizzy from a wrecker for $85.

How are you testing if it holds vacuum?

Crap
One of my best mates owns a workshop and we used his vacuum gauge. I tried it myself by compressing the spring and holding my finger over the hole where the hose goes and it didnt hold so then I tried the gauge.
Nik

If you have time there's a mod I've considered but just haven't had time lately to tackle-
If you don't use the EGR valve ( I have about 100 spares here) I've thought about taking them apart for the diaphram rubber itself . Since they are subject to high heat they are a bit tougher than the disty ones. The distributor rubber is just crimped inside the housing , shouldn't be that hard to open up and re-crimp.

I'd also search around, it's either made by Denso or Mitsubishi , another one for another make should work .
Sarge

Thanks Sarge Im going to look through my spares and see if a 1300 1 will fit.
Nik

hahaha you will be looking through tthem spares for months nik, clean your mess up

I found a few spares, most were buggered too! I found one that works off a 1300 they look very similar so I,ll give it a try.
Sarge I tried to uncrimp it after a few goes and skinned knuckles I gave up
Nik

Carefully put in vice and tap with small punch to open it up . but don't over tighten vice as you may damage it . let us know how you go .Boner

Ok, got some time yesterday and starting tearing into diaphrams . The EGR was easy enough to get into and remove it's rubber section . The vacuum advance, however, wasn't nearly as easy. The way they crimped that thing at the factory suggested someone may use it for an anchor point ! By the time I got it opened it was destroyed and the two diaphrams really aren't all that interchangeable anyway .
Oh well, live and learn .
Far as I know, the diaphram/advance for the 1.3 and 1.6 should be the same . Suzuki didn't like re-tooling on much of anything , which is a good deal for us .
Sarge

So it wasnt just the way I was doing it!
Its hard to tell if it made a difference having a vacuum advance that works this thing is geared so low now it runs out of gears before you get to see the potential of the motor.
Nik

Just have a look around the wreckers for what you want and can maybe adapt. For example im pretty sure the diaphrams on old carby cruisers are rebuildable
