I did this wright up a while ago on another forum thought I would pass this along.
Looks like I should take my extra bolt back out then! Thanks!

geb63619 is right. The Hydro unit in the open frame tractors is mounted to allow for flex. Over tightening or adding additional cross members will result in a broken transmission. As for the broken frame, unfortunately this is somewhat common on 430's. Worn out hydro dampeners and decades of hard or even abusive work will sometimes crack the transmission mounting flanges on the frame. 430's have a ton of torque so beefing up these flanges is a good idea. My 85 430 is still crack free but I do keep an eye on those flanges and will beef it up at the first sign of trouble.

I know all to well about the broken frames I have fixed 318 420 and 4-430 tractors all with the same issue these frames are no big deal to weld up. What most of use have found if you watch the bolts going into the axle housing and the cross member bolts and keep them tight you will not have any issues. If the your rear end comes loose this is what breaks or cracks these frame tabs.
Here is the process I have used to fix all mine
1st picture is what I started with
2nd Picture is the print from the 3/8 Steel I welded back in place
3rd picture steel all welded in place with gussets back to the side of the frame.
If you haven't checked your open frame tractors for loose rear ends you might wanna think about doing so before it gets this bad.
If I find them only cracked I grind the cracks out weld and using the same above print but only 3/16 thick steel and reinforce the area and gusset.

I am VERY glad my frame was broken, because I'm sure the PO thought it had hydro issues & wanted to slick the problems over to someone else. Otherwise I never would have been able to buy such a machine for just $1200!
