Just returned from a trip to sunny QLD and got stranded about 200 klm's from
home. On investigation it turned out to be the harmonic balancer on my 92 model 80 series LC had developed a bad wobble and in fact was no longer on good contact with the crankshaft.
While I hoped it was just a simple matter that the rubber binding had separted (as is common in older holdens and fords), I was dismayed to find that it had stripped the key way on the crankshaft. I now have 2 options, one get the front section rebuilt, or replace the entire crank. (either option is not that cheap)
I have done a few searches and there doesn't appear to be any problems like this discussed previously. Has anyone had a similar problem? If so how did you go about rectifying it? Also for future reference, is there a telltale to indicate this sort of problem is developing so it can be nipped in the bud early instead of letting us down out in the middle of no-where?
Cheers
Peter

Hi Peter,
I had
mine go on my old rig whilst on a trip thru outback SA (never happens at
home - and took me a while to work out what the problem was).
Mine was the front pulley that powered the A/C and so I left the belt off and crossed the fingers until I got
home. If yours has done the same part there is only 4 bolts holding the pulley/harmonic balancer on and I simply replaced it with a second hand one for $100 and about 20 minutes work.
Mine was on a 1HZ. Yours must have done some more damage if its done what your talking about.

Thanks for the replies. It would seem this kind of failure is quite common. (as mentioned as
well by the toyota repairer who now has the vehicle.
They are to remove the crank and send it to a local repairer who has done (hundreds) of these where he builds them up then machines back.
However had I caught it earlier, it might not have been such a major repair. My problem is, what to look for? (short of pulling things apart on a regular basis.)
Also Now I need to decide do I go the whole hog and get the rings/cylenders and head checked while I have all the bottom half dismantled? it has only done 270,000 but it has the usual problem of the TD series where it blows
grey smoke especially under acceleration. (in for a pound, in for a dollar)??
Cheers
Peter

Happened to a few of our Cruisers, we pulled the cranks and got them built up and then we traded them on Patrols. Building them up is successful.
