I recently purchased a 492 New Holland Haybine in great shape with the acception of the wobble box. Uppon removel of the wobble box I found that it was not only dry inside but rusty into the bargin. My local dealer informed me that even they won't attempt rebuilding these gearboxes and only sell Remanufactured units.

I have learned that New Holland no longer offers the specs for rebuilding this gearbox to even their dealers. The wobble box is actuially very simple. I'm looking for any advice on the yoke preload and any shimming specs that any one has to offer. I have a dial indicator, micrometer and I know how to use them just need some pointers on what kind of end play or preload I should be looking for.
