I have a Versatile 400 swather early 70's model. I need to replace both wheel bearings on the left side. Not super familiar with this stuff so am learning, do i need to press the bearings on the shaft? If so how do I press the bearing on the inside once I have re-installed the the axle shaft? Any help would be appreciated, thank you in advance.

Almost all axles in farm equipment have tapered roller bearings in opposition to each other for support and location of drive wheels. These, and seals must be applied in sequence to allow assembly. to do that in unfamiliar mechanisms, take sequential pictures as it is taken apart. Some inner Cone and rollers need to be driven off, or removed with a puller. Some are easily removed with a light hand fit. Grease them before installation, and keep things clean. Watch youtube demos on hand packing new tapered roller bearings. Use ring shaped drivers to install seals or high levels of patience. Jim
Might be the diagram.

There is a Rule of Thumb that 1) the
bearing race that is stationary relative
to the load should be a slip-fit on its
seat, while 2) the bearing race that
rotates relative to the load should be
press-fitted on its seat.

An example of this practice? Sure!

Consider a standard two-wheel-drive
pickup: 1) The rear wheel bearing race is
press-fitted onto the rotating drive axle
while the outer race is slip-fitted into
its stationary housing. Conversely, 2)
the front wheel bearing outer race is
press-fitted into the rotating hub and the
inner race is slip-fitted onto the
stationary spindle.

If the picture Jm shows the bearings are ball bearings and look to go into a casting bolted to the gear case from each side then bolted in on the shaft. Probably a gasket didn't look for that and probably filled with oil to lubricate the other parts in there. As for the packing with grease if they are already sealed you can disreguard that part if open one side that would go to the inside so it is oiled by the gear box oil as it runs and again no grease needed since it will be running in oil though I would probably either dip it in oil just before asssembly or put some into the bearing as I turned it so it has oil from the git go.

When I look at that diagram, I think about how many different parts for machinery (and other stuff) have been manufactured by mankind since the beginning of time. One part for eveery molecule in the universe maybe?
