WATER PUMP BEARING QUESTION
I just bought a new water pump bearing , genuine Yamaha for my 85 RZ350. On the old bearing , the balls are exposed both sides.
On the new bearing there is a form of shield on one side. You can still see the balls through slots in the shield. Does it matter what way it goes in ??....thanks

Re: WATER PUMP BEARING QUESTION
I would install with the shield-side facing the water pump seal and the balls exposed to trans oil. Unless someone else has an engineering reason to reverse that call.
Re: WATER PUMP BEARING QUESTION
Is it a metal or rubber shield?
I agree with brrrappp, that logic makes sense.

It looks like plastic , but it has radial slots in it , so you still see the balls. the old one I took out was open both sides.
Re: WATER PUMP BEARING QUESTION
If you're worried about the shield, remove it.
Re: WATER PUMP BEARING QUESTION
The O.P. didn't post a picture of the bearing, but I think what he is seeing is the plastic that is used to keep the balls properly spaced between the races. I don't think what he is describing is a shield at all.
In any event, if it looks like it would in any way restrict oil from lubricating the bearing, then face that side toward the water pump seal. The bearing is lubricated by being open to the oil in the transmission.

Re: WATER PUMP BEARING QUESTION
No , it is a shield , flush with the ouside face of the bearing. Not the cage that keeps the balls properly spaced. I am pretty familiar with most types of bearing , just never seen one like this. It is factory Yamaha too

The plastic is meant to retain the grease inside. That being said, as far as I am aware, that retainer should face the outside.
And as already mentioned, if you are truly concerned with it remove the retainer and use it as the original bearing was installed.

That's not a shield that's a plastic cage that keeps the balls spaced. It's a very common type also .
