What kind of machines had a T-20 in it?

There's an entire thread on that here:

The T20 looks heavy

They weigh about 70 lbs.

The T20 looks heavy

I'm 150lbs and I have no trouble muscling it around by myself, but its nothing I'd ask the wife to move.

Too many to list. The problem with trying to buy an old machine just to get the trans is: often they need complete rebuilds. There's $350+ in parts to rebuild one depending on what is wrong with it. Watch this http://www.6x6world.com/forums/conte...kid-steer.html An old machine that has been sitting is likely to have the drums rusted up...if that happens they need to be turned and polished. Since you are close to me you should come over and check out my machines......maybe have a beer or two.

The Terra Tiger is a decent machine. it was my 1st amphib. Light weight, yet strong fiberglassed bodies. The components are all stressed members meaning that the engine and tranny all add strength to the other components as well as the body. The weakness of this design is that if the fiberglass body fails, then everything is susceptible to failure. I think if someone was serious about an overhaul they would come up with a space frame made of high strength steel, then attach all the components like a conventional amphib with a t20. That would take some time and effort, and the machine is fairly small sized. Playing devil's advocate, I don't know if its viable to do all that since there are many used Max2's out there that come equipped with all the right stuff. Don't get me wrong, there are some finely restored Terra Tigers out there that I'd love to have. But its easy to sink several thousand dollars into these machines before you know it.

I've seen people get a good T-20 out of an old junk machine (the T-20 was still good) for a few hundred bucks. I've seen used and rebuilt ones for sale here on the site from $500-$750, so they're not too pricey, considering you're going to be buying the best AATV transmission ever built.

I got some ice and garbage out of mine today, I can see some floor now.

Whats one of these t-20 transmissions cost? they dont look cheap.

"Is there a issue with the fiberglass not being strong enough?" Actually, yes! The bodies were formed around plywood for stiffness. In most cases, the fibeerglass has cracked and let in water, and that rotted the wood away. Some guys have cut out the old and glassed in new marine plywood.....others have grafted in frames/reinforcing metal.
One of the biggest problems they have is the cone clutches...A.C. had the "fix" of adding washers to the springs to hold more tension on the cones. The drawback is the fiberglass sides would flex taking away spring tension. A t-20 would be perfect! .......and I might just have a good motor for you. The original TT's had a 10 hp 2 stroke, the later ones had an 18HP as an option.

OH, hey HyroMike

Terra Tigers don't have perimeter frames. The individual drive components (engine, transmission, flanges, axle-holding thingies) are independently fastened to the fiberglass body versus being attached to a frame. Here's a picture of the innards, and what I mean.



An alternative is to build a frame and have all of the drive components attached to it, and then bolt the frame into the body. Something like this:



Basically, the frame holds the body on. On my Swamp Fox, the body is just an ugly wrapper that helps the whole assembly float.

The there a issue with the fiberglass not being strong enough?

Im not sure what a full frame is yet but Ive seen some pictures so I have an idea what your talking about.

Here you go.... http://www.6x6world.com/images/broch...ug-adapter.pdf

That's for the 4 on 4". The 5 on 4.5" template is here.... http://www.6x6world.com/images/broch...plate-dims.pdf

Southern Michigan, ay? That's Buggyman and Larry W (and lots of others) land! Stay away from them, they're overall just bad influences.

You can add several hundred pounds and still be safe in the water. To my knowledge, nobody's put a full frame in a 'Tiger yet, and we've all been looking for a first victim. We choose you.

Other then cleaning it out I dont have any plans on doing much work to it any time soon. I have a tractor Im fixing up to sell and a wrecked car I bought. Then we'll get on the Tiger.

I really like how these terra tigers look, although I think it looks more like a frog then a tiger.

Where can I find the diagram for building your own adapter plates?

So, where is "here", anyway, Mike?

You certainly have a project on your hands, but the tough fiberglass bodies of the Terra Tigers make them a pretty cool build. "Mark M." is a member here on the board, and from Western NY, like me. He has a beautiful silver 'Tiger that he's rebuilt, and re-engineered into a great trail machine. He doesn't have any pictures posted in his gallery, but I know his avatar is a shot of the machine. He slipped in a Briggs Vanguard, and actually built a reverse mechanism on the stock transmission. From talking with Mark over the years, I think the biggest problem he has with it is the amount of heat the engine puts out right next to your feet.

The one piece tires can be replaced with newer rims/tires by building a simple adapter plate that adapts the old 3-lug flange to a standard 4 on 4" ATV/golf cart rim bolt circle, or upgrade further to a 5 on 4.5" Argo/Max/Mudd-Ox style rim. You can fit a solid 22" tire under that machine and have pretty good clearance. Heck, you could even replace the cone-clutch drive with a T-20 if you wanted to. Build a full frame, put a v-twin in the back, the T-20 under the seat, and have loads of leg-room. The sky's the limit, and if you can do most of the work yourself, you can get it done within a reasonable budget.

I live in southern Michigan

I want to be able to use the beast in the water, Im not sure how these things would take the weight of any modifications in the water.

I have 3 welders, and a lot of metel working equipment and always enjoyed getting old machines going again.
