Chris,

 

My recommendation is to get one of the large ¾”  (900 + ft – lbs) air wrenches.  I got one for $99 and it earned its keep  the first time I had to get the big nut off.  2 seconds and it was loose.  In fact, had a gent load his rotary in his car and drive 90 mile round trip to my hangar – for the 2 seconds it took to get his loose as well.  He had spent three days trying to stabilize the block and using a pipe on a wrench ( as well as many of the methods you attempted) to get it loose, all which failed.

 

Believe, me you’ll love it for that purpose alone – not counting all the other uses.  I had a smaller ½” 300 ft-lb air wrench but it just wasn’t up to the job.

Bob,

 

I have removed the big nut, but I don’t mind you asking.  It is usually the little things that trip us up.

 

I have tried heating all the way around the counterweight.  Lynn wrote and suggested heating only one spot.  So I will try that next.

 

I’ll keep my fingers crossed.

 

Chris

OK guys,

 

I need some help.

 

I can’t get the counterweight off.  I’ve tried the puller, and heating the counterweight, but it didn’t work.

 

Does anyone have any cool tricks to help? 

 

Thanks,

 

Chris
