the '74tii is broken .....


Recommended Posts

Early last Thursday morning I'm all packed up for a long weekend with friends in Chino and Pomona.  About 10:15am I'm in Chino blasting south on the 71 Fwy at Central Avenue and ..... (slight crunch felt) ..... the engine just quits running.  1-1/2 hours later the tow truck drops me and the '74tii at Le Tran's shop in Ontario.

 

After some weekend troubleshooting and discussions, this morning we're confident it is a "fuel delivery" problem and the KF is the culprit.  So he will remove the KF and get it shipped off for a rebuild.

 

Cheers,

 

Carl

Bummer!  

 

Which loaner car did he give you?  

     DISCLAIMER -- I now disagree with much of the timing advice I have given in the past.  I misinterpreted the distributor curves in the Blue Book as timing maps for our engines.  I've also switched from using ported-vacuum to manifold, with better results.  I apologize for spreading misinformation.

Definitely not the drive belt.  My most-wildly-hopeful hope is that the KF drive gear is "for whatever reason" slipping on the shaft.  But I don't see any sort key/keyway that would have sheared and caused that "crunch."  So we're thinking something let go inside the KF

 

Le was kind enough to give me a green loaner ..... with automatic trans, and totally cool roof rack.

My thought exactly.  But as I noted in my first post, there was a definite "slight crunch."

 

And after removing the KF from the car last night, Le discovered that the KF "obviously" did some sort of "major hang up" internally because the brand-new KF drive belt actually broke .... which may have been the "crunch."  He says the KF does now rotate by hand, but it is not smooth, rather sorta/kinda "gravel-y."

 

Which is interesting and corroborative, because that 100% instantaneous power loss symptom I experienced on Thursday morning was the exact same symptom I experienced in 2008 when my original-issue KF drive belt broke while driving on a SoCal freeway ..... which made me think Thursday's failure was KF-related, rather than electrical.

Jeez...sorry to hear that. Thanks for keeping us informed. Definitely interested to hear what is found inside and what the fix is.

I wonder if it's oil or lack of oil related. Always a concern, as you can't inspect oil level or oil quality easily.

I've never had oil leaks to the KF, and one can thus only assume the KF is always getting full pressure & flow. I change oil + filter every 3,000 miles or so, so quality is always good.

No doubt.

I just wonder if the KF self-cleans and gets full pressure same as the engine. I agree it should, but have never seen inside to confirm.

Ken,

   yeh, just last week the '74tii was zooming all around Simi .....

 

Rebuilders: 

Fairchild up in Redding, CA is where Le is sending mine (Fairchild has done several for Le, so I have full confidence).

Pacific Fuel Injection in San Francisco

JF Pro in Van Nuys, CA 

and I think there is a place in New York ??

 

Cheers,

 

Carl

    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
