The Ruckstell I am working on is stamped Hall-Scott. When I did another setup I noticed that the P146 was shorter then the one I am working on now but didn't even think about it being a problem at the time as this one was sliding in and mating with the bronze plate when I took it apart. The teeth looked good so was gong to reuse it.
With all new innards this one does not even come close to engaging with the bronze plate to lock the unit. While the collar that the thrust bearing slides down around on the old plate sits a little higher then the new one, when I sat it on the housing there is still a gap.
Anyone know why and when this part was changed?
Except for the spider gear housing that I no long have, all parts look to be the same size. I don't see anything in the repair book under this part that helps. When everything is assembled it all fit together correctly except the sliding clutch. I will have to order a new one but I am just wondering.

Mark, The P146 Sliding Clutch Gear should be 4.185-4.190 in. long. If you have a shorter one it has been modified. The P146 mates with P147 Gear Locking Notch Plate when in the Ruckstell position. It does not mate with the P139 Bronze Thrust Plate. The teeth in P139 simply allow the P146 to pass thru. In direct drive the P146 is locked to the P145 Thrust plate holding P144 Sun Gear stationary. There are very minor variations in the Ruckstell parts but they are all interchangeable. None of the Perfecto parts are interchangeable with the Ruckstell. Hope this helps. Glen

Yes Glen that helps a lot. Thank you very much. The notch plate, well "BIG DUH" on my part! All is good now. :-)
