engine and drivetrain Is this normal for a gearbox ?

[Pacs]

Hi guys,

 

New to the BMW 2002 scene. 

Just got a '73 1602 with a wide body. But the car needs a tone of work.

And one of the biggest things i can't understand is why does my gearbox stick have so much play in it.

 

Is this not the original gearbox on the car? 

Please see the photos and video bellow and let me know what you make of this:

 

Any feedback is greatly appreciated 

 

Regards,

check the mounts where the shift platform connects to the transmission...

 

part #11 and various bolts

Hey Pacs,

 

Welcome to the forum. Tons of info available on this site, and the forum members are supper awesome to. Very knowledgeable people here.

 

That play on your shifting platform doesn't look right at all. If I were you I would jack the car up on to jack stands and get underneath with a flash light. Get your fingers past the drive shaft and exhaust and try and push the shift platform up and down and see why it is moving so much.

 

Now that shift platform is connected to the transmission using three points of contact.

 

The first two points are at the front of the shift platform where two metal tabs bolt the platform to the rear end of the tranny. Look for them with a flash light shinning down the back of the tranny - just make sure they are there. You will be able to get a ratchet with an extension and tighten bolts for #11 in above post

 

The third one is a cross brace (#19). One end bolts to the platform while the other end bolts to the lower part of the tranny. Check that this is in place

 

Start there.

 

Regards

Whoa....it's certainly unconnected somewhere. Gonna need a shifter rebuild kit, and likely some other parts.

 

Give Steve a call at Blunttech for the kit.  https://www.blunttech.com/products/3182220

 

Also read about making some replacement bushings for the dogbone link 

Go to RealOEM for nice exploded views of particular parts and systems.  http://www.realoem.com/bmw/enUS/showparts?id=ST12-USA-06-1971-114-BMW-2002&diagId=23_0774

 

Rebuilding the shifter isn't complicated, but if you have big hands, it's easier if you drop the driveshaft... then you can replace the Guibo, since you are there (scope creep)

While were on this topic...before I tore my car apart we all noticed the stick shift went too far forward to shift into first or third. So far in fact, you would mash your knuckles into the radio.

While tearing it down I haven't noticed anything weird with the linkage underneath. The transmission (and engine) are now out of the car, but what would make the stick go so far forward? Internal tranny linkage?

 

Sorry to hijack the thread...

Pacs,

 

+1 the two bolts (part #10) at the top which fasten the whole shifter assembly to the transmission.

 

 I'm guessing the right-side bolt is missing, I recently had that very same problem.  And way back when, those bolts would loosen up ...... I would re-tighten ..... they would loosen ..... they refused to stay tight for long.

 

These days I bought a slightly longer bolt and use both a lock washer + lots of blue LocTite, and I still climb under there on a regular basis and check for tightness.  

    And being slightly paranoid at times, I bought 2 extra bolts + lock washers and carry them in the car everywhere I go.

 

Cheers,

 

Carl

Nick,  more than likely the shift lever (the part the shift knob screws onto) is installed 180 degrees backward.  

 

see this...

The spring clip that captures the washer that sits on top of the spring is missing.  The washer, shown on the top of the spring, captures the spring in a compressed state on top of the ball. The spring clip, looks to be in the picture as well, fits in a groove machined around the inner circumference of the shifter platform well on top of the washer thus capturing the spring compressing the ball into the nylon cups.  Make sense?  Look at the real OEM for a graphic of the correct order of assembly.

Well, that's certainly a poster child for deferred maintenance.

 

Bushings all around, a clip, and off you go.
