I used my 2 ton engine lift to raise the lawn tractor mower front end high enough to do the repair job easily. 3 of 5 screws attaching jack-shaft to housing broke. Could not remove the spacer from old main shaft to replace with new shaft. Hardware store for new screws, I had metal tubing on hand to make a new spacer. This old machine is working again.
Thanks, for having all the parts I needed.
