OK, we're back whoo Hoo!
We stripped the mower to just the chassis, verified all the pulley's and levers were good and stripped the steering, and most of the connections. (the previous pic shows the front end partially broken down) As it was original only to be e rebuild we didn't completely dis-assemble the chassis. It was in very good condition and would have been a waste. We did of course take to it with a toothbrush and many miscellaneous cleaning implements to make sure it was as clean as the rest of unit.
Many hours and much frustration.
Any shafts were slid out and tested, if needed greased, cleaned, lubed or spaced with the correct washers for good tolerance and minimum play.
