shear plate broke, HELP

[BHD]

I have a old new Holland, 850 round bailer,

I have posted two pictures out of the parts manual,

the hub #3, attaches to the out shaft of the gear box, and then there is a shear plate #4, and the shear plate is keep in place via the drive shaft, #6, but on the end of the shaft there is a plate that the shear plate catches, via it has two ears,

I looked up other models of Hew Holland round balers, the other have a similar set up in the PTO shaft side but all use a from of that that strike plate that allows some movement about 160 degree's twist possible,


the reason I am asking is the shear plate shattered, (it is cast iron) and they want $535 for the plate, and $346 for the hub and it has had a crack in it for years, and the shaft with the strike plate has broke and has been welded,

OK I do not think the baler is hardly worth $800+ but still need to use it, and I can make a new steel shear plate, but I am not really seeing the need for the strike plate,

Can any one see a reason, and if it is to give a small amount of alignment I can solve that with a chain coupler, it appears to me that the shaft end goes in to the hub for support on that end, I have not taken it apart yet,

any Idea for the strike plate and way it is made, with the shear plate.

Any idea why they would design that with shear plate turning the strike plate on the shaft, and not a direct shear plate to the shaft,

before and after models of this type of baler has solid shaft in this area and the shear on the PTO, but still do not use a solid shear they use the same design with the strike plate on the shaft?

ANY one know why?

After you get it off I'll be going to a machine shop and see they could make a new one out of stock steel. Doesn't look to hard to make by the picture.

that is basically the plan for now, thank you,
