FYI – Picked up a 1990 PM66, low miles but sat unused in a garage for the last 10 years. A spritz of silicone spray got the tilt wheel gliding nicely but the raise/lower wheel was STIFF. Took everything apart – top, motor, trunnion out (thing is HEAVY) and found the shaft had congealed junk on it. The PO had used some kind of grease which had worked its way down into the shaft housing and turned into viscous paste. Also filled the teeth of the tilt/raise mechanisms with gunk. Pulled the main bearing shaft to clean it too. All is now shiny and going back together. Any wisdom on the best sequence to reassemble the main bearing shaft and the raise/lower mechanism? My guess is: Unbolt teeth from tilt/lower part. Drive in Main shaft. Put in raise/lower shaft. Then bolt on teeth meshed to worm drive on raise/lower shaft.
Anyone with practical experience doing this who has a better suggestion for assembly sequence please share.
The arbor spins nicely and the belts look brand new but I suppose that I should replace arbor bearings and belts while everything is in pieces…....
