Hi im a new member but not new to mz
the tool pictured is the proper crank case splitting tool it would require a correct to drawing clutch puller and a further tool the name of which escapes me now.and I don’t have my manual to hand.
I have a fully equipped workshop and could price up the tools and make any in the rear of the factory manual.
Years ago whilst heavily involved in mz I made a set so making is not an issue.
I would personally recommend that the correct tool as shown is used it may avoid negligent damage to the crank cases.
other useful tools are the oil seal application drifts allowing refit of the seals without removing the engine from the machine.
please ask for any more info
