White FB31 4wDrive Problems

[shakenbake]

I have a White Field Boss 31 and have a problem with the 4 wheel drive engauging. There is a lever that shifts the 4w in and out. This lever used to have a little bit of a resistance to it. It doesn't anymore. I drained the oil and looked up into the gearcase but couldn't find anything much. The lever is connected to a rod that runs along the outside of the case down to a lever that runs into the case on the left side. When I was under the case looking thru the bottom cover I could slide one of the gears left and right, engauging the 4wheel i think. I did not take off the other cover where the actuator lever is connected though. I left the gear in the position I thought was engauged and put back together. The 4 wheel worked for a little bit. Now this was in the middle of the winter and I needed to get the driveway snow blowed so I was in a hurry. After I would say about one pass I did not have 4wd again. I let it go until now I would like to blow snow again this winter so I need it fixed. My brother looked into it and found that the lever that does the actuation was worn off. He made a replacement but still no 4wd.

Does anyone have any ideas that can let me know how this is supposed to operate or what I can check?

Any help would be greatly appreciated!

Thank You.

I will try and help. Slide the cover back on your front drive shaft and engage the 4 wheel drive. See if the drive shaft will turn(opps forgot to add you have to have front wheels jacked up first) and if you cannot turn it your 4 wheel drive is engaged. If it turns your problem in in the transmission. I have the same tractor and I had the spline strip on my front drive shaft inside the coupling behind the front axle. If it is not here pull the cover off your front axle and check the ring gear out. The bolts fell out of mine and I had to replace the ring and pinion gears and the new bolts are wired. Hope this will help you out. Ivan
