That's OK, Muley is entitled to his opinion. The fact I run a facility that manufactures specialized components out of exotic metals for powerplants is not really a factor... or the part where the information that I provided is based entirely on what is in the photo that I posted above from a real, live, original Tucker track laying on my shop floor. It’s hard to see in the photo unless you know what you’re looking for, but several of the cross tubes are triangular, not round or square, and they came from Tucker.
Perhaps Tucker tried to keep things simple for a couple of years after 1965, but that didn’t really happen. As one example, remember the fiberglass pontoons? Most everything changed a lot, and apparently still does. Tucker told me a month ago (when I ordered parts) that the rubber track system that was on my 1958 was not available until 1978 and that the conversion that mine had required extensive axle housing modifications. I’m inclined to believe it since I’ve been dealing specifically with it over the last 3 years.
On my 1953 Tucker, the u-joints had the caps held in place by straps across the outside of the yoke. On the ‘58, they were held in by internal ‘C’-clips and a 2-bolt strap across the side of the cap. I have also seen the one’s where the caps press in from the outside of the yoke with the ‘C’-clip in a groove on the outside. No, they are not interchangeable and yes, Tucker used them all at one time or another combined with Dodge 8.25" diff’s/axles, Dodge 8.75" diff’s/axles, and a later a variety of Dayton’s. Maybe I didn’t swing my hammer hard enough to get all the parts from these different components to fit together since they were all the same?
Transfer cases and yokes? No, they were not the same over the years and since the yokes and stub-shafts are used to set the tapered shaft bearings the spline depth and yoke length is not only critical, but seemed to be specific to the unit. I’m sure modern CNC machines have removed that issue with the latest Tucker transfer cases, but that’s not always been the case.
As for the pontoons, the early 443's had a 5-bolt bearing plate on the outside, 3/4" welded machine-steel rails, and 3/4"-wide rollers. The later 443A’s and 500-series had a 6-bolt bearing plate, 1" rail that bolted on, and 1"-wide rollers. They are not interchangeable without extensive modifications.
Just for fun, Google "stud bearings" and "cam follower bearings". Tucker made their own and they were unique in the length and diameter of the stud verses the size of the roller on the end. If the grousers had more ‘meat’ in the area where the stud mounts then there would be a whole host of options that would work. I you were to make your own grousers, an off-the-shelf "flanged stud bearing" could easily be used. Not really rocket science here.
The rubber-track frames changed several times also, especially the length and I.D. of the pivot tube that goes over the axle housing. The latest one’s have an insert bushing in them instead of metal-to-metal contact between the tube and axle rings. Even the wheels have changed from the 12" rim, 1" rubber wheel to the 10" rim, 2" rubber wheel. The width of the wheel hubs and diameter of the shaft seals and seal collars have also changed over the years. Durometer of the rubber varies depending if the wheel is used as an end-wheel or a middle wheel. Urethane wheels are yet another story. My rubber tracks use the hy-fax wear bar over the top of the frame, the new one’s use rubber rollers, neither are interchangeable since the frames are different.
Mild steel grousers riding on steel pins would spall quickly and fail without any type of bearing. Are there any bearings between the pins and grousers of a steel-track Tucker? No. That’s because the grousers are grey cast steel which has a Brinell Hardness around 700. They are brittle and the rollers do break off if you bind them up. The track pins are not pure stainless steel, just have a high nickel content to help prevent rusting and are also hardened. This substantially reduces the friction between the two and allows a Tucker track to work without any bushings in wet conditions. Are the cross tubes cast? No, they are ‘mild steel’, and have to be welded to the cast with high-nickel rod. You know, something like 309L STAINLESS?
I do find it interesting that someone would believe that Tucker never experimented throughout the years with their product and all the parts are interchangeable.......
Again, maybe I’m just not using a big enough hammer. OR, I could just be making all this up to hose a fellow cat owner. If you believe that, then I have a friend in Nigeria that needs some banking help.
