How to Dissasemble, Hynautics H42 Helm Pump

[barkdee]

Rebuilt the pump four years ago and can't remember how I got it apart. Does the back end pull off first? Is a gear puller needed to pull it? I believe there's a snap ring on the underside of the front end(steering wheel end) so the shaft needs to be pulled to get at it and the seals.

Usually disassembles from the back . Plan some way to catch all the ball bearings.

Removed the back plate but the shaft doesn't want to come out of the round piston housing. Tapped it lightly, don't want to whack it hard until I know it should come out. Yes, the ball bearings, I'm working on a folded up towel for that.
