Some help forterra to crystal

Hi all quick question.Would a rear half axle from a forterra 10641 fit into a 6 cyl zetor 12145?..

I cant tell, but the UR3 rear axle looks remarkably like the UR2 and it wouldnt surprise me if the same blueprints were used. Both were 80mm axles, the UR2 had 5300kg rated capacity, the UR3 had 5500kg rated capacity. A contractor here, had Ursus tractors pulling 14m3 Schuitemaker manure tanks and he broke wheelflanges off the shaft due to wide 800mm floatation tires, as well as breaking rear axle housings. Things got worse and worse because the casting quality of the parts was worse than the existing parts used on the new tractor. If the UR3 parts would fit, it would absolutely be an improvement over UR2 parts from Poland, because ZTS is bankrupt and UR2 parts now come mostly from third party Polish suppliers.

If they would fit (??) Forterra HD rear axle portals would be best. on paper they only give you 500kg more over the old style, but in practice they will have the capacity to bounce around with 3t trailer drawbar load, where UR2 axles fatigued...
