Advanced Bearing Technology and Durability

they're cast in michigan assembled in texas michigan some cats some aluminum casting happens in texas that's really cool rare to see these days when would somebody step up from the like the more budget or entry level hd line to these uh if you were going to uh like say if you were considering running like ball bearing precision 6766s or something as twins on your five liter mustang or something like this this would be a good alternative to running precision this would be probably a step up from precision in most ways because the alloys of the parts non-rusting of the parts the double piston rings on both sides the angular kind of variable preload angular contact variance is a list of features there's a feature set there that is present in the zona rotor that's not in the in the pt turbocharger uh that helps with longevity and durability on these things the double piston rings the variable preload everything's a super alloy in it there's no there's no corrodible rust-able parts in this you don't have problems with so this is like the bearing set i would use in a 600 horsepower tdo5 tdo6 build okay and then this is this is stock bearings in a bone stock s400 now it's a lot larger shaft diameter is bigger the quill diameter up in this area on s 400 this is where the compressor wheel sits okay much bigger this one you only have the support from 270. it's totally adequate for for a cummins or a motor home right yeah this is like you know if you had s400 on a motorhome these are the bearings that are in it they go more they go half a million miles there's no problem with this stuff but we want to start hitting it with anal ag and two-step and you know uh you know uh jerry wants to delete the blow-off valve and you know all this other stuff starts happening you know sometimes it's better to up armor these parts what's uh what's in this one it's in between these two so this is tdo5h this is to4s based bearing structure here so this is not regular t4 size bearings but what garrett did when they needed to make a slightly bigger more robust version for john deere sometime in the mid 80s they've redesigned the bearing housing with a larger turbine side piston ring seal larger interface where the shaft attaches to the where the head attaches to the shaft larger piston ring larger journal bearings and larger thrust bearing and we're using essentially a ti4 so4 bearing system in that okay it's about halfway between these two and again keep in mind also this is not…
