The tool was opened just slightly by wedging open and used a large pair of circlip pliers to gently draw the tappet into the clamping fixture.
Once in the fixture I threaded a short 5/16 bolt in the other end of the cross drilled hole to give me a place to place a pair of sockets and extensions that held the fixture in position so the lifter body could be worked back and forth while the tappet was held in place.
In the beginning, I didn't think the lifter body would move. It was unbelievably tight. Finally got it to begin moving. I quickly understood why the tappets break when trying to remove ballooned lifter bodys. I struggled for close to an hour and only got it up about .020". at this point I went in for dinner and thought on it for a bit. Went to the super market and bought dry ice to pack into the lifter body in hopes of a couple tenths shrinkage while the holding fixture warmed with a heat gun to possibly gain a few tenths. This seemed to help and the lifter body began of lift out of the tappet with rotating movement while pulling up and against the holding fixture.
Patience, thought, and some home made tooling prevailed! I was sweating bullets for a while, wasn't sure it would extract. I can't begin to explain how pleased I am to succeeded in this phase of the planned repairs. After considerable clean up to ensure there were no contaminants the new lifter was test fitted. It slid right in and fit very well. What a delightful sight to see at 12:30 am in the morning. A much longer time in the garage after a day at work than planned.
I don't know if anyone has done this, but I sure am happy to not have to remove the front of the engine, pan, and camshaft! If this is a new approach to an occasional problem I hope I have described it well enough for others to try.
