Thread: 300 TDi crank pulley bolt....

I'd love to get one of those, but my tool purchases are rapidly eclipsing the worth of the car. Sanity, or at least my version of it, will have to prevail.

Anyway, I have just returned from a 7500 km journey, which took a week, and my you beaut hit it with a big hammer impact wrench has arrived in my absence.
I'm keen to try it but it's after 3AM, and I just got in. Best I get some sleep. I'll report.

So,the impact tool and a mini sledge hammer don't work.... This is getting ridiculous.

I cant believe this is still going!

I tried to change the timing belt on my 300Tdi once... i tried the starter motor trick and some heat but couldnt get it undone. I ended up leaving it and sold the car a couple of months later

I sold it for other reasons btw.

Cheers

I found the same thing with the one I purchased a few years ago.
Mushroomed the top of the tool.
Gave up . Purchased the crank looking tool and 3/4 braker bar with a 5ft pipe.

In saying that, a bloke (non forum member) has just done the same and managed to snap the bolt inside the crank.
His balancer is also broken around the keyway.
I assume it was overtightened when he did a rebuild 12 months ago and the bolt has bottomed out an damaged the threads.
He now has a big problem to deal with.

The overtightening thing is worrying me. I made up a crank locking bolt as per Dave's (blkknight) instructions, but I think it would break with the leverage of a 5' pipe.
I think I'll try heating it up as much as my propane torch can give it and try again. If I have no luck I'll give up on the timing belt for now, put the head back on and save up for a; a cordless 3/4 rattler, or b;, pull the engine and put a V6 in it.
I've had tough pulley bolts before, FIATs are notorious for it, but this is ridiculous.

Neither can I

On the other hand, the thing probably would undo the nuts on the Scania...
