Sincere thanks to all of you who shared your experiences and offered 
advice

on this issue; especially Mike Canfield who sent me a replacement bolt.
After some delays and struggles we got the new bolt in.  This was
accomplished with the aid of a 7X16 lathe, a beer can, some crazy glue and
some shorter than standard M42 drill bits.



I plan to do a write-up with some photos in order to help any unfortunate
future victims of the broken crankshaft bolt.

Hi All:



My son was driving his 3-pedal 1980 240D ( with about 300K mi.) yesterday
when the car began to run warm.  Suddenly he heard a loud PLINK, and
something falling out of the engine compartment.  Then the engine 
overheated
and he began to lose coolant.  The following very large (18mm thread) 
broken

10.9 bolt with 3 thick washers was recovered:

Aside from running very hot the engine seems to run normally.



Does any of you have an idea what happened and where this bolt came from?



He will be driving SWMBO's TDI Jetta until we sort this out.



TIA,



Greg

I was thinking regular center punch and a hammer.
If an auto center punch can start it turning, it's not stuck very badly and can 
probably spin out easily once it starts moving.

Mine turned out easily with a screwdriver on the broken remains. Try it.

Good call on Omega.  A used OE is the right bolt.





I was about to suggest something similar.

Re: [MBZ] 240D Mystery Bolt????- UPDATE

[Greg Fiorentino]

Thanks Grant:

I had already decided to make a bushing using my MicroLux 7X16 lathe.  If
the old bolt head works ok for this, fine.  Else I have some CRS 1018 stock
to turn to the right OD, then drill from the tailstock drill chuck for the
proper clearance hole.  I also have a set of LH drill/extractor bits that I
plan to use once the pilot hole(s) are drilled.

A quick tip:
If you have access to a metal lathe, or someone who does, take the broken
bolt to the lathe and drill a pilot hole through the head and the body of
the broken section of the bolt.
Use your best judgement as to the size of the pilot drill hole, doesn't have
to be large but should be large enough to not break the drill. Then use the
broken bolt as a drill guide to drill the exact center of the remaining half
of the bolt still in the crankshaft.

You will save a lot of effort by having a pilot hole in the broken part
still in the shaft. Second drill a little larger, etc until you have the
size you need to use the broken bolt extractor.

With the bore hole well located in the center, the extractor will work much
better and your chance of success will greatly increase.

I also suggest the use of Left turn drill bits for the last two or three
size increases in the pilot hole.. sometimes the drill pressure will walk
the broken part right out as you drill it.

All the best success.

Re: [MBZ] 240D Mystery Bolt????- UPDATE

[Dieselhead]

The original is a 10.9 (the metric equivalent of 8).  Yes, I'll not go lower
than that.  OTOH if the bolt were to be highly stressed again, I would
rather the bolt break than the female threads in the crank be damaged, so
I'm going to call the 10.9 optimal and not even consider a 12.9.

Considering the awkward location for drilling, I think I'll turn a bushing
on my lathe to keep the drill centered and straight.  Just about any

Mine turned out easily with a screwdriver on the broken remains.  Try it.

Good call on Omega.  A used OE is the right bolt.

Get a OE bolt.  You want  the real thing.  It is a stretch bolt.  You can by
one from a junkyard, someone on the list may have one for free, or try
Potomac German, or one of the many vendors in the Star. 
A quick search for a crankshaft or engine block on car-part.com will give
you a long list of junkyards that have the engine.  Then you can call them
and ask if they will sell you a crank bolt.  As last resorts, you can
contact a stealership or the classic center.

Re: [MBZ] 240D Mystery Bolt????- UPDATE

[Dieselhead]

Good news!  We pulled the pulleys and there appears to be no damage to the
crankshaft.  The 2 keyways are semicircular, the keys are little cylinders
about 9mm in diameter and about 10-12 mm long.  I've never seen other than
rectangular keys before.  Apparently once the Belleville washers are gone
they just fall out, causing slippage of the pulleys (but saving the keyways
on the crank and pulley).  The bolt remains will have to be drilled to be
pulled.  We may be able to get this done on my boy's next day off if I can
source a new bolt locally.

Thanks again for all the help!!!

Get a OE bolt.  You want  the real thing.  It is a stretch bolt.  You 
can by one from a junkyard, someone on the list may have one for 
free, or try  Potomac German, or one of the many vendors in the Star. 
A quick search for a crankshaft or engine block on car-part.com will 
give you a long list of junkyards that have the engine.  Then you can 
call them and ask if they will sell you a crank bolt.  As last 
resorts, you can contact a stealership or the classic center.

The original is a 10.9 (the metric equivalent of 8).  Yes, I'll not go lower
than that.  OTOH if the bolt were to be highly stressed again, I would
rather the bolt break than the female threads in the crank be damaged, so
I'm going to call the 10.9 optimal and not even consider a 12.9.

Considering the awkward location for drilling, I think I'll turn a bushing
on my lathe to keep the drill centered and straight.  Just about any
material will work for a 1 shot tool.  1018 CRS machines easily.

I think I might ask one of the on site vendors about sourcing the bolt.  

If not available here, I think I'd not look at anything under grade 8 , (c:

Start dousing it with penetrant now. Kroil or 50-50 acetone/ATF.

Thanks to all who replied.  ALL of the hints and ideas sound good to me.
It'll be a week or so before I have the time dig in to this.

The 400 lb. ft. sounded strange to me.  I do have a torque wrench that goes
up to 250 or 300, but couldn't find any 400s online even.

I'll let y'all know how this progresses.

The book says 270-330 Nm (200-244 ft lb).

Well, it's high, but it is not 400 ft-lb, which will indeed break things.
IIRC, it's something like 225 - 250 ft-lb. All my manuals are packed away,
or I would look it up.
