GOLD Site Supporter
as much as I like to restore to original specs, I would not put the box back on, but rather create a storage area in the coffin and have a hinged door in the floor of the flatbed, the coffin area is just wasted space, unless you take the fuel tanks out of the cab and built a custom tank in the coffin area, thus giving you more room in the cab, that would be the best choice IMHO.
thank you for posting the photos of the restoration.....
Built the new thrust washer this weekend for the front of the trunion pin. Also built a thin washer for the aft end of the pin to take up axial slop and give a better thrust area than the back side of the trunion hold down clamp was doing.
Here is the pin before the washer was installed, I had to machine the fillet weld down a bit so I could get a good perpendicular thrust face on the angle head of the trunion pin.

Here is the new thrust washer:

Here it is installed:

Here is the thin washer on the aft end, just next to the roller bearing, everything is tight now, but not to tight, slop is gone and good thrust faces are now in play:

My recommendation would be to use a wear metal for the thrust washer surfaces for long term service.
That current setup if all the same material will wear your fine work over time causing you to redo it all. Although maybe not until the next lifetime.
McMaster Carr should have what you need like a bronze or hardened bronze.
Check out my 1443 thread for what I used.
If you are looking for bomb proof, here is another idea to beef up the trunnion cross member. Also, turn another trunnion roller to decrease the wear on the fifth wheel. Better to have two rollers, as shown, as they will revolve at different speeds. One long one works too. Splitting of the hair.
Agreed on this. That is a massive amount of Sno-Cat to only be able to carry two people inside. This is 'coffin' option:
That "coffin" option is way cool, I now understand. This one I am going to have to think about. One issue I have is this is where the exhaust pipe and muffler were located, if I go with this option I will have to figure out a new path for them. Now for my personal dilema: I want to keep this unit close to original, that is what I did with the Frandee. After 8 years of working on the Frandee to keep it original (as well as I could) it has tainted me. I don't want to ruin this machine by making significant modifications. When I get in it to drive I want to feel like I am still driving the same unit they made back in 1966. Sappy, ya, but that is the way I am. Also, this may sound crazy, but eventually I want to make a camper I can place on the bed. I think that would make for a great adventure rig. Take the Tucker and the Frandee, leave the Tucker as base and drive the Frandee around, or whatever. Dreams dreams dreams.
Now for these great ideas that have been coming my way like the "coffin" and the improved trunion, and whatever else may pop up, well I bought the Tucker frame from the 543 this spring up in Washington, then I bought the 500 series pontoons from the Tucker factory. Now it looks like I may not be using many of the parts from either of these purchases on the 543CF. So what does this leave but the makings for a custom Tucker like snowcat from these extra parts, hmmm the ideas, I need to get retired so I have time for all of this.
