74tii distributor replace or rebuild


kubes

Recommended Posts

Ok after having trouble shoot why the engine misses on the 74tii, I believe I have a bad distributor. The vacuum retard is bad for sure, it leaks. Also the distributor wobbles a little when the car is running.

Can you buy just the vacuum retard diaphragm? Is there any in the North East that can rebuild 2002 tii distributors?

I have a few other distributors, how "bad" would it be to use them?

0 231 115 071 / JFUR4

0 231 170 164 / JFU4 (from a 75?)

0 231 115 072 / JFUR4 (from a 76 auto?)

I'd rebuild it. I've been trying to find even a worn '74 tii distributor so I could get it rebuilt, but I have not had any luck yet. I am using a '73 and I can't get the idle quite right.

I've been told that Precision rebuilds them (see link below), and I'm sure anyone who does Tii work could probably point you in the right direction.

In the meantime you can use a '73 tii 008 or "rebuilt" version 002 distributor. It will run fairly close to stock.

Do NOT use any of those other distributors listed, if they are for a carb'd car the advance curve is too much and you will knock/ping like crazy with too much advance.

just pick up the keyboard and order

a new mechanical advance distributor,

and be done with it - you don't need, and your wont

be able to tell the lack of vacuum advance.

If you don't set it with a timing light ,

nothing matters- you might as well fit a JohnDeere

distributor - your loosing power with guess work.

BAVAUTO - the longer you wait - the higher the price to

pay for powerful smooth running motor.

This distributor does not have the correct curve. Its close, but its not 100% correct, especially for a '74tii

Your post leaves me confused. If the vacuum retard is bad, plug it up and run without it. Your best bet for performance would be to replicate the distributor of the prior years.

The fact that your distributor wobbles is far more troubling. How is it wobbling? Are you speaking of the shaft, the body, the rotor? The distributor was not made to space age tolerances and given its analog design, there is a tremendous amount of lateral play in the upper shaft. Is it also possible that the rotor does not fit snuggly? I would take a timing light to determine if you can get a rock steady timing mark. If you can, the wobble as you describe it, is inconsequential.

You mentioned the other distributors you have. Any one of them could be pressed into service to get your engine to run well enough to drive. Obviously, these other distributors will not provide optimum performance. However, they can sure demonstrate the difference between a worn distributor and a tight one. I would have no hesitation to use one of these other distributors as a core to rebuild your tii distributor. The only practical difference is the centrifugal advance mechanism including weights, springs and supporting apparatus that lie below the points plate.

Determine what is wrong (if anything) and cannibalize the parts you have!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
