Worked on the 46GT deck today. Replaced the double pulley and bearings, the bearings had spun in the housing and were ready to fall out. Funny because the bearings were not seized up. New bearings fit sloppy in the new pulley so they got some loc-tite bearing mount. Used my needle grease injector on the idler pulley bearings. Had to replace a step washer for the idler arm. Had to weld one of the wheel mounts. Pretty much just little stuff but it should make a nice grass killer. This deck will go on the 1641 that I'm loaning to my step son. The 48GT that is on the 1641 will go on the 1864.
