1951 Frazer Manhattan Power Windows

[DTort96646]

Any one have any info on the Trico Lift-o-matic, Vacuumatic power window lifts for the 1949,1950, Kaiser Virginian and 1951  Frazer Manhattan. I started rebuilding mine and would like any info that any one has regarding rebuilding the units. I've read the service bulletins available, and my units do work, but they are a bit on the nasty looking side and as long as I'm in there, I may as well rebuild and lube them.

The Trico units were used in the 4-door hardtops; he never said 1951 Kaiser Virginian, he said 1951 Frazer Manhattan (at least that's what it says now). 

Kaiser-Frazer's only service information I know of was the Service Bulletin issued in the 1949 model year.  It will cover all the cars he listed and there is conflicting evidence that a very small number of 1949-50 Frazer Manhattan 4-door sedans might have had them as well.

Dale Hammon & his son Steve once tackled rebuilding the Trico system in restoring a hardtop at their shop.  You might want to ask them for ideas.  Dale is a member of the club and lives between Janesville and Beloit WI.

I have read the factory service info and the units were only serviced by Trico at the time. I have a source for the cable and gaskets, but the diaphragms are going to be tough. I have one spare diaphragm, but was curious about the winding of the spring at the "up" end of the lift. I'll continue to experiment. Thanks for the info.

This will be an issue i need to deal with in my convertible if the same system.  Was expecting them to be hydrolectrc like the top but i see may be different.\Sk

Your convertible should have hydraulic windows that operate from the same pump that handles the top. The hardtops used the pneumatic system.

I do apologize to you Fid, I did edit the post to mean exactly what you said. I just grouped the years and then added th vehicles. My real question was info about the Vacuumatic window lifts. Sorry if I upset anyone.

Spent the last two weekends cleaning, replacing the cables, painting and lubing my four Trico Vacuumatic/Lift-o-matic window lifts. Cleaned the filter and lubed the compressor/vacuum pump too. The factory service bulletins were a big help. After some careful disassembly, counting spring turns, and making some specialized tools to disassemble the vacuum cannisters they work  like new. They have adjustments on the solenoids to control the speed of the windows. They also have a feature that slows the windows at about an inch from full up. A little complicated with the vacuum routing so it's easy to see why vacuum windows didn't catch on.
