Manitoba | I have never done them without having the wobble box off and having the a frame completely out but you might be able to just unbolt the knife backbone and knife head off of the wobble box and leave it attached but it will be awkward with that weight still on it
Remove nuts both sides of a frame, unbolt the bearing holder on outer side (2 bolts backside 3 in front I think) there are prob some shims under there and remove that outer holder
The a frame should then slide out
Both bearings/bushings will have a snap ring holding them in place
The bearings are ceramic I believe and if you look closely they will be cracked, they are meant to be although I really don’t understand that
If the bearing holder is worn badly they have to be replaced or redone, not so bad on the removable one but the weld on inner end not so easy unless you cut it off
On last one I did I tried using bearing mounting compound as there was only a touch of wear but haven’t used that head enough yet to know if it worked or not
Hope that helps | |
