Anyway.... here goes.



 

 

They have about 60 to 61 inches in length on the ground each. They are 17 inches wide. This gives me aprox. 4080 square inches of surface area. The drive wheel is 15 inches tall. Take your average 30" tall tire and cut it in half, I basically get a 2 to 1 reduction right at the wheel. The center of the hub when mounted is 24 inches from the ground. That is the ground clearance achieved with a 48 inch tall tire! With no lift on the vehicle.



Speaking of vehicles, I am currently using a 1986 Grand Wagoneer. Why? Because I have it and because I can. It has D44's front and rear, 2.72 gears in the pumpkins, a fulltime 4wd t-case, (not quadra-trac) and 235/75r15 tires. Quite the wheeler eh?

I had to re-inforce the outer edges of the tracks I purchased. These things are at least 30 years old and are showing their age. I purchased 2 inch wide strips of 2 ply belting from Alaska Rubber to bolt to both the inner and outer edges of the tracks. This would help with the broken ends, and provide some added strength to the outside edges where the drive teeth run. I used aprox. 750 1.25 x.25 bolts, nuts, and 1500 washers. Fun. They turned out well.

They have removable plates that bolt to the drive gears which allows you to change bolt patterns. I can mount them on just about anything. However before I can run them on an 8 lug rig I think I may need spacers to clear the brakes.

I weighed the Waggy at work the other day using airplane wheel scales. they registered around 1000 pds on each front tire, and 800 poounds on each rear. Not sure I trust them as they were at the begining of their measuring range. So lets say 4750 pds. with me and gear. 4750 divided by 4080 = 1.16 pds per square inch. Not bad. (Edit. Did some research on curb weights. G.Waggys were somewhere around 4500-4750. So figure 5400 loaded. 5400 divided by 4080 = 1.32 pounds per square inch.)

How did they work? Great! Steering is an issue at times. Thats alot of material to move across uneven terrain. I have an idea of a larger fullsize steering box (bolt in) and modded pump. We'll try that first and if it doesn't do the trick we'll do a ram assist. Also, the tendency of the track to want to lift in the rear when up against a tall object showed up durring the test run. If you go up against a large stump the track will want to torque over. Or if you go down into a hole with an under cut bank it will do the same. In time I would like to engineer in an angle on the front to help with this but for now I'm content. They ride very smooth in snow. On frozen ground and ice they are rough. With no cushion of air like inside a tire you get to feel all the little bumps a tire would normally absorb. But I love the "point and shoot." These things will take a bone stock Waggy places it has never even dreamed of going.


What a poser...

The main bodies and wheels etc. on these are all made from aluminum. They are easy to move around, but not as easy as a large tire. Mounting takes some time as you have to get the vehicle lifted up to the 24" level and then position the track just right to slide over the wheel studs.


Getting one in position.


Lets roll!

Ahhhhhh.........Remember the old days of 70's hot rods jacked up in the rear............

 

 

Just for comparisons sake...........Ben's on 35's......


Instant ground clearance.

Got clearance?
