Sealed bearings

Postby minkbigbird » Tue Aug 05, 2014 6:14 am

G'Day all. I am replacing the seals and bearings in the PTO and flat belt drive on my SAV. and have noticed some ware grooves in the shaft's from the old leather seals, is it practical to use sealed bearings to prevent oil leaks? thanks.

Not entirely positive it will stop any 'seepage' past the bearing. But that's what I did on a couple of Cub right angle pulleys used on Mott mowers. The only downside is I had to plug the oil galleries so that cut off the vent and pressure will build up. Working on a vented fill plug (3/4") but haven't found one yet. I did get new seals, but they are more for looks and to keep junk out.

For the PTO it's almost a no brainer, better quality bearing (SKF) for less money. The CaseIH ones are now made in China! Same bearing in snowmobile idler wheels (6205-2RS) so I know it will outlast the Cub. Found them on eBay.

BW, try looking for the type of vent you want here.

Thanks for your help, it has to be better than just a new seal on a worn shaft. One more job ticked off the list.
