Hello everyone

fixing a 85 XJS after engine fire.
dizzy is seized (as usual) and I have it removed from the engine and disassembled.
I cannot get the rotor shaft off to save my life.

Could not tell if I had the screw or the plastic disc.
It appears that I had the screw and it was stripped because there was a metal washer under it.
Tried to use micro extractor and would not budge.
I tried to drill it out and planed to remove the screw afterwords but it did not work.
I soaked it for 10 days with PB Blaster before drilling it out.

I know the metal on top of the shaft is thin but appears to be thicker at the base where the springs attach.
Could I try to use some thick material to protect the metal and put vice grips on the gear and on the base of the shaft and twist?
Would heating it up first help?
Is it possible that the fire fused these two pieces together.

The dizzy was not directly hit by the fire but I'm sure it was exposed to the heat.
Any suggestions would be appreciated. I am running out of patience and fighting off using brute force.

Thanks to everyone for your help.

 

Post a pic of the bit you are talking about, as I am not clear. I have just taken one to bits, so I can probably give you some pointers. You should not need to drill anything, however seized it is.

I'm not 100% on where you mean but I will post some pics of the dizzy in different pieces in case the perspective is useful.

Do you mean the top screw that holds the outer sleeve into the inner one? I believe thats a pretty dinky screw you should be able to drill out easily and tap again later.

 

In most cases, I prefer to fix things rather than toss them. But, there are times....


In the case at bar, I counsel getting a good used one from David Boger at everydayxj. Good guy, posts here from time to time. Lots of good used and even NOS stuff.
