Many years ago I took the engine/gearbox out of a Maxi...def no high tech!
Had to replace a gearbox lock washer but no “special tools” available hence the strip out.
Reassembled engine/gearbox.

found a spacing washer I had missed.
Repeated the split/rebuild and unit back in the car. All ok.
Full day job in my uncle’s farm barn using his block and tackle to lift the engine.
