Adjusting mechanical clutch


Trackmagics

Recommended Posts

Any tips on adjusting mechanical clutch? With the clutch fully depressed I cant get into any gear without major grinding. Just got in another used tranny and am hoping its a clutch adjustment problem. I messed around with the adjustment nut that pushes the clutch lever for awhile but wasn't able to adjust it correctly.

Any tips or ideas appreciated.

All clutches are mechanical. The question is is the throwout bearing operated by a hydraulic cylinder or with a lever, operated with a linkage. Hydraulic: the cylinder may be shot? Mechanical: the throwout bearing or actuation arm inside the bell-housing may be broken. (this goes for the hydraulic too).

Poke around and see if you can get a clue.

Good luck

all 1600s and 2002s with VINs below 1665200 (approx build date March '69). The 1600s have a mechanical linkage; the adjustment is in the pushrod that goes from the pedal linkage to the withdrawal fork that holds the throwout bearing.

The early 2002s have an adjustable pushrod that connects the slave cylinder to the withdrawal fork. However, from experience I found that I went over 90k miles before I had to adjust mine--in fact it wasn't until then that I discovered it was adjustable--you normally don't find an adjustment on a hydraulic clutch...

I believe the problem is in the adjustment of the pushrod connecting to the fork, but after loosening and tightening the adjustment nut I have still not been able to solve it. It seems as if the clutch wont fully engage in order to get the car in gear without major grinding.

play as shown in the manual, and the tranny still grinds when you try to engage a gear (this presumes an all mechanical 1600 clutch, not the adjustable hydraulic one on the 68-early 69 2002s), then it may well be clutch time. Either the disk is worn past adjustment, the throwout bearing is worn, and/or the withdrawal fork is worn. You should also check all the pedal-to-fork linkage pieces for wear; a little slop in the linkage translates into greatly increased lost motion at the fork end. On the hydraulic linkage, the same can be said--if there's lost motion in the hydraulics (leaky cylinder) you'll have the same results.

You might be able to postpone the enevitable by placing washers behind one end of the pushrod, or even making an extension to get that extra few millimeters of movement. But...all thing being equal, you probably need a clutch.

cheers, and sorry 'bout that

Thanks for the reply. I am going to mess around with it a bit more and try to figure this out.

The clutch had zero problems before I put this new (used) tranny in the car, so it's making me have doubts that it is a bad clutch. Are there any chances this is a bad transmission or does it sound solely like a clutch issue?

Hope its not a third bad transmission, I might just give up on this car.

    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
