My many thanks, to all who reply to my Thread.
I appreciated all your posted answers.
But I ended up pulling out old three wire cable.
Then I used an air compressor to blow out all the crap left over inside the
conduit which also got rid of any standing water inside conduit.
Then I wire lub a grease rage, and pull that thru to the end.
With the new four wires assembly, the two of us pull all four conductor
thru the 2" pipe. I gave a third guy the job of lubbing the conductor's
before they enter the conduit.
Everything went off better then I had anticipated. All four conductor
went thru the conduit, and around the two 2" 90 degree elbow, without
any problems.
Again I want to say thanks to all.
THIS JOB IS NOW FINISHED, ALL IS WELL.
