Congratulations Dan, looks great! I recall that Dan Williams instructed me to put some cheap 80-90 weight
oil in my new top loader and then take it for a couple of slow laps around the track making sure to not exceed 4,000 rpms and then drain the
oil and fill with a high quality 80-90. The idea was to flush out the packing grease and remove any metal pieces as the new gears mesh.
Hope everything goes well. Saw your other posting and do not have anything to suggest regarding the spring.
Jim
