Splitting a ZA50

So with the help of several folks who contributed to my moped army

forum thread posted here, I was finally able to open up my ZA50.

The technique I used was to use a flat punch to strike on one of the

top tabs near the rear engine mounts to start a small gap. I then

used a thin flexible taper's knife to slide between the halves.

I worked my way around the case, bending and twisting the knife

to eventually pop the case halves apart. Some corrosion on the

2 dowels were causing the engine halves to stick.

Though it's mostly intact, I plan on replacing this thin

paper gasket with one made of Teflon. I'll post about this

if I am successful.

Here is the clutch side half of the ZA50.

Here is the stator side of the ZA50. The drive shaft gear

is in great shape.

Crankshaft and clutch side bearing, excellent shape. I don't

think I will be replacing this.

Same with the stator side crankshaft bearing. There is a

little corrosion on the crank, but nothing that should cause

any problems. It's just from sitting and not running for so

long.

All in all I'm glad to have split the case. There is some filmy gunk

in there that may have destroyed my Polini kit. Now I'll be able

case match this sucker and be confident that nothing inside it will

creep into my new piston and cylinder.

I'll have to smooth some of this out as well.

It should be a productive Thanksgiving visit home for me

this week. Turkey, stuffing, grinding and buffing...
