488 haybine

[pjbofmn]

I have a 488 haybine with a bad wobble box. It broke off the sickle. Now can I use one from 469, if so how do I take it off. I take the hub cap off with cutter and nut and the bearing dont move. Like there pressed in place or am i missing thing?

They pull hard the first time and are pressed on.

Should read not pressed on.

does anyone know what the preload is supposed to be on the wobble shaft bearings on a 489 New Holland haybine. I presume it is preload instead of backlash because they are Timken bearings and whoever put the box together that my son has on his haybine, did it wrong because the input bearing is in a few pieces. I was very surprised finding that to be the case, I think that the wobble box is over built in that area.
Thanks in advance for any info
