Kyosho Hanomag Input - Conversion

[kartman01]

I have a Kyosho Hanomag wheel loader that is complete but is missing 3 jack screws for bucket up/dn, bucket tilt and steering. I was hopeful of tyring to reconstruct the jack screws to keep it as original as possible, but am now thinking this may be a great project to convert to hydraulic actuation or perhaps use off the shelf linear actuators to replace the stock units.

As I am a complete newbie at this, I would appreciate any help in terms of which might be the best way to approach this (hydraulic vs linear actuator) and if there is anyone out there who has done a similar conversion who could guide me to sources of parts, etc.

Has anyone ever done this kind of conversion on a Kyosho Hanomag?

Thanks!
