Hello everyone,
I bought a Modern AG Competitor 5 ft shredder with a Kubota B7800HSD (my first real tractor!), and when I revved up the shredder the first time I noticed dark gear oil coming past the seal where the PTO shaft connects to the shredder gearbox. There is a good bit of play in the bearing (easily 1/32 of an inch) where the input shaft hooks up to the gearbox, so I thought I might as well replace the bearing and not just the seal.
I already know I need to find some flat snap ring pliers to remove the internal snap ring, but I wonder if the bearing is also pressed onto the shaft or into the housing around the bearing (or both). The bearing seems pretty stuck in its housing, but that may just be due to rust.
Does anyone know if I will need a bearing puller to get this bearing out? The nearest Kubota dealer can replace the bearing and seal for about $125 in labor (unless they decide to charge more), but I would love to do it myself. This is the the first time I have taken apart a gearbox like this, so I am not sure if Modern AG builds them differently than others.
I am hoping someone in this forum has taken one of these apart. I asked one of the mechanics at the dealer if the bearing is pressed in, and he didn't know. The bearing at the other end of that shaft came right out of the housing (at the back end of the gearbox), and it is pressed onto the shaft. This is a 48HP Max gearbox. I am attaching a couple of pics.
Thanks,
CuriousGeorge
