Adjusting Sunroof


Scott W. Long

Recommended Posts

Dear All:

Thanks for all your help with my 1972 BMW 2002 tii sunroof.

The sunroof operates well with my new crank- good!

With the sunroof closed, it sticks up a little above the car roof.  
How can I adjust the sunroof so it sits below the level of the car roof?  
This will reduce wind noise when closed.  
Thanks:

Scott

First, make sure the two long side rails are actually sitting on the metal roof frame. There are 2 plastic location “forks”.

 

The rear is adjusted by a notched D cam piece (one per side).

 

The front is adjusted by knurled nuts at the sliders.

Dear jgerock:

Thanks. 
Tomorrow, I will check if the long side rails are tight to the roof.  
* Where can I find the 2 (two) plastic forks?

* Where can I find the knurled nuts?  
What part of the sunroof should I lubricate and not lubricate?

I have purchased BWM sunroof grease and am ready to go!  
Thanks:

Scott

If you’re not familiar with a 2002 sunroof, perhaps you should spend some time looking thru others build threads. A terrific reference website is www.my2002tii.com.

 

The (2) plastic forks are located at the ends of the long aluminum side rails. They locate the rear of the rails into holes in the roof frame.

 

There are (2) aluminum knurled nuts on both front slider sides of the sunroof mechanism.

 

BMW changed the design of the front sliders in about 1974. They are not interchangeable.

Scott:  PM me for the column I wrote for the Roundel that covers removing, replacing and adjusting 2002 sunroofs.

So, the plastic slides and nuts are located on the underside of the sunroof?  
They can not be accessed without removing the sunroof?  
My BMW is a 1972 2002 tii.

To do anything on the sunroof mechanism (other than the crank handle itself), you need to pop the sunroof inner liner piece and slide it back into the sunroof cavity.

 

The knurled nuts simply screw up and down to adjust the height of the sunroof. Once adjusted, the two front guides (sliders) can be resecured.

 

The rear height adjustment is part of the sunroof cable itself that bolts to the rear of the sunroof “cassette”.

 

You must be careful when making any adjustments, since raising it up too much will make the sunroof scrape against the roof.

 

First picture shows the little adjustment pieces that attach to the rear sunroof guides.

 

Second picture shows the rear guides still installed in the aluminum rails (sunroof removed from the car).

This picture shows what NOT to do.  The black plastic “fork” is in the correct position, but the long aluminum rail is above the fork tines. This will raise the sunroof up too high in the back and most likely it will rattle around.

 

My recommendation is to insert the fork into the long rail first, then slide the rail into the roof cavity.  A flashlight is helpful during this procedure. 
 

Note the headliner is out in this picture. Since the headliner is the first thing installed in the car, you will only see things from the sunroof opening.

Dear jgerock:

I was looking at your picture again.  
I noticed a black hose with a hose clamp.  
Is this one of the four (4) sunroof drains?  
It is a large diameter.  
Thanks:

Scott

 

Scott-

You are correct. These cars have (4) drains.  Two front ones run down the A pillars into the wheel wells.  Two rear ones (unfortunately) run down the C pillars and dump into the rockers.  That usually ends in rusty rockers. The fix is rerouting the rear drains thru the wheel wells.  I copied what Keith Kreeger did to his 74tii (www.my2002tii.com) on my 69.

    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
