Tried to rebuild a worn out box. Got a new steering shaft from Greece. Same measurements as the old one. Turned out the new shaft and one bearing were wrong. All the seals they sent were wrong.
Went to Applied Technologies; They called ngk ordered one bearing and used the old seals to order new ones. One seal on the pitman was not available but the same size only 1mm shorter in height was available. Parts came in. Found out the steering shaft would not seat on the box: a 1.20mm gap between the column and the box. Tried the old shaft The column would seat on the box but it still had1.10mm up and down play in the shaft. Then found out the bearing race on the new shaft was cut 1.00 mm longer than the old one. Trying to fudge it I used fiber gasket material to make shims and still have a good feel for the bearings to have some preload. Bad part when doing all the fit and try found out the bearing races would fall out of the top column seating for the bearing and the same with the one in the bottom. Well dummy put in the new seals adusted the preload on the rack to the gear. Centered left and right. marked the pitman arm and in the tractor we go. and hour later jacked up the front axle Left and right both between center were just about even. Between 1 1/4 and 1 1/2 turns left and right.
then left the tractor down. Turn right no problem full turn. Start to turn left and large crack in g noise. play then it turns left. Even tried to adjust the stops on the front balls to take out the hard right. Still large crack and it must be the bearing races jumping from pressure. Backed off on the pitman gear and no difference. I had tried to center punch the column where the bearing race sits and the bottom where the race sits. Even put jb weld on the outside of the races to the colum and base of the box to try and keep them from turning. There was not that much pressure on the bearings when put together but something is shifting in there. there is no side play in the pitman gear. // Anyone know of a replacement box that would fit a 4 wheel drive b700 as for parts a B7100 seals and shims do not fit.
