It probably is a cat engine but it is not a CAT backhoe front axle because they use ZF not Spicer and that spicer axle probably has interal wet brake in it. I think it looks kind of cool. I wander what they use it for?MR4WD said:Interesting. Looks like a very low production vehicle, whatever it is. It's hard to tell without a side shot really, but I'll take a stab and say it's some sort of "off-road" military aircraft moving equipment. Low height, high weight. It seems to be cobbled together from different parts from different machines. I'm betting the front axle is the same found on a Cat rubber tired backhoe, or some other sort of slow moving implement. It also appears to have a cat power plant, and no brakes on the front diff meaning it would almost have to have planetarys and a hydro-static tranny. The 4 links seem to be off a semi's rear suspension, panhard bars or dogbone links (whatever the application) along with the front panhard on this rig (connected to 3/4" plate?!) The coils seem and links seem to be an afterthought for this diff, leading me to believe it's still a front axle out of a cat rubber tire hoe.
Wait a second, upon further inspection even the frame appears to be cat. You can see where the pivot would attatch to the frame for the front swinging suspension. (beside the oil filter) it's almost like somebody ditched the hoe body and built a suspension and body for a hoe. What's the back and side of the machine look like?
