Have a new window and hardware for the top front window, the one that rolls up and over the operator's seat. (wasn't me I swear) The only place I see to get the rollers in is at the back of the cab, but there isn't enough room to get the window frame far enough back to enter the track. Anyone done one of these animals?
On my excavators, the windshield lower roller brackets unbolt, and the uppers are integral to the glass frame. With both bottom brackets removed, the glass frame, with rollers, is rotated in place, then each bottom roller bracket, with roller, is bolted on.
