I'll give them a bit longer to see this. In the meantime I'm tantalisingly close to splitting the case the hold ups are the piston wrist pins on pistons 4 through 6.
Pistons 1 through three were easy. I removed a circlips on each one and the wrist pins slid out with finger pressure.
Pistons 4 through 6 won't do the same. The wrist pins all look like they are hitting the piston.

Was I lucky with 1 through 3? Is some force required to extract these pins? I don't want to damage the pistons.
