Ha Ha,
pretty funny, reminded me ,many years ago I had a Daihatsu delta 5 speed gearbox in a 4wd, had to release the input shaft bearing , I stripped out the gas oven in my caravan, so I could fit the gearbox in it, and got some heat into it, so it would let go of a very strong bonding agent on the housing and bearing.
Just like bakin a turkey!
Worked well. Unfortunately I don't have advice on a puller for you though.
