PTO driveshaft bearing lubrication

[bminchey]

While I have the driveshaft bearing out of the bellows, does this bearing need to be packed or lubricated? I noticed on the engine side there is a small gap. It turns pretty well but I don't see how this bearing is very lubricated. At first I wondered if oil did the job, but the bellows was dry and clean and I don't think oil is getting past the oil seal. I've seen some posts referring to a zirc fitting. This machine doesn't have that.

The bearing is the seal and is lubricated by engine oil.

So the rubber membrane seal in the PTO cover does not prevent oil entering the bellows and the bearing? That seal looks like an automotive crank seal. When I took this apart, it had been sitting for three years so I didn't see much oil in the bellows.

Thanks!
