G'day
I posted a while back about my atempts to repair a Landcruiser crankshaft keyway with devcon and appeciated the help and advice so I thought I'd fill you in on where its at. The devcon was a dismal failure on the two attempts I had at it. Don't go there!
With nothing to lose we had a crack at welding the crank today. At first we were going to weld the key in place, but then decided to try and build up the crank so the key could still be removed.
It involved laying some weld along the damaged key way, grinding back, more weld, more grind and finishing off with a dremel.
The final result was really pleasing. I think we may have done it...
The key slotted in snugly, the balancer went back on and with loctite everywhere it will hopefully not need to come off for quite a while.
If you are interested in pics then you can see them here on my blog.

How did you get the bolt to the 300 odd foot pounds it is required to be set at?
If you didnt, i would strongly advise you make a balancer holder and get it torqued....i have heard many stories of these coming loose mainly because the right tension couldnt be reached without a great deal of work....there is no other way totension it than making a spanner...
Someone i know had the key fall into the timing gears, which cost him a new motor.

I didn't.
And yes, it was difficult to get it tightened up.
Hopefully it'll work, but now I'll be keepng an eye on it. If all esle fails I guess we'll tack a bit of weld onto the end of the crank and hold it there that way!
