Thanks for the update Bonnar Bloke. I have been trying to remove the boss from a Victa 125 without success by the two hammer method. I might try the 50/50 atf acetone brew before my next attempt.
Maxwestern that's the perfect puller for this application. Nice sound and evenly spread load that won't damage either the puller or the boss.
Gadge, for me, WD40 is code for penetrating oil of your choice, but WD40 has worked for me in the past in getting a siezed height adjuster going on my Victa utility after a week of soaking in and I recently found three near full cans of the stuff!
I was told that WD 40 is among the finest substances on a molecular level, hence why it can find it's way through the finest gaps.
