Hi y’all,

In process of putting back together this 92 with the used om602. Got excited to try it out and went ahead and mounted the engine with out the trans. Everything fired up and ran perfectly. I’m thinking there’s light at the end of this tunnel so I make a push to wrestle in the trans from underneath.

As soon as I get the trans in I notice that I can no longer rotate the engine.

Pull everything apart again and this is what I find
- engine rotetes just fine with out the trans attached

- the output flange of the trans rotates free, spins all the way through to the smaller splined shaft at the front.

- The larger/outer splined shaft will not rotate. See pics

Can anybody help me confirm what this means please?
