Sealed bearings normal in a R154?

[Blackmk3]

Hello there supra community, Im currently stripping and inspecting a R154. Im from New Zealand and its a JDM Gearbox (if it makes any difference)

Im replacing the 1st gear thrust washer and anything else while its apart aswell

But the question i have is the bearings on the main shaft are sealed (as in they have there dust caps installed) the main input shaft bearing and the center housing bearing. Is this normal? as in factory toyota? it seems abit odd i would have thought bearing life would be much longer with cooler oil running through it

The Lay shaft (bottom shaft) have all open roller style bearings

I know my old w58 wasnt sealed but ive never had a r154 apart hence asking this question

Thanks!

Bump help anyone? im sure there's been plenty of r154s apart before...
What im pretty much wanting to know is if i rebuild it with new bearings am i better to leave them sealed or take the caps off and let the oil do its work?

Thanks
Nick

There are a few sealed bearings you will have to press off or use a puller. It's completely normal.

Just leave them as they are.
