Welding a 1.3L Crank?!?!

As some of you know, my 1.3L crank was messed up due to the timing belt pulley bolt backing off. It caused the woodruff key to shear and messed up the end of the crank pretty bad. I have another engine to drop in, however I have been busy with work, moving, and fixing up my house that my renters trashed, so it is still to be done.

In the mean time I have talked to some of my gear head friends and two of them have told me of instances where they have welded a timing belt pulley onto a crankshaft because of the same problem. One welded a big block Chevy and the other, a crank pulley on a VW engine. Both of my friends have said, "Hell the crank (1.3 Samurai) is already screwed up, might as well give it a try". One said to just align the number one piston at TDC and position the pulley on it's timing mark and put a tack weld on it to keep it in place. Tighten it down and then proceed to finish welding the pulley with a couple more short spot welds making sure not to overheat the crank.

I think I am going to try this next week when I get some spare time. Anyone else ever hear of this being done to fix an engine? The engine ran like a champ before this mishap so I see no reason not to try it. It would be a shame to tear this engine apart when I know it has many more years left in it. The crank is already wasted and is not even good for a core. Any thoughts?

Re: Welding a 1.3L Crank?!?!

It's certainly doable... but the thought of doing that scares me.. it will work and all but what about ifthe timing cover has to come off?

Re: Welding a 1.3L Crank?!?!

The timing belt cover would not be a problem to remove since it is on top of the timing belt pulley. I will still bolt the alternator pulley on so it can be removed later. If this works then later when I rebuild this engine I will have to grind the spot welds off, but again, the cranks is already wasted so I really can't mess it up.
