I agree with Johnny on the Ball Roller Bearing. The Ball / Roller
configuration triples the radial load carrying ability.
The Original Bearing used in our Pumps was an NSK 885858........885
signifies ball/ball. Later a 665858 was developed.....Ball/Roller.
NSK no longer makes any water pump (integral shaft) bearings. They sold
the product line.
.
I have found recently that Auto Zone advertises a Ball/Roller version for
our pumps. The part #*L58-295H is said to have upgraded to a ball /roller.
I ordered one and it came with an bearing end stamped with an NSK 858 with
no prefix, either 885 or 665. I later found that an "R" in front of the
858 would have signified It was a ball/roller. The pump I received had no
such marking...only NSK 858. So I cannot confirm what bearing they are
using without removing the bearing grease seal making it unusable or
returnable. **I'll keep digging and report back.*
*However, A company in Cleveland makes a NEW water pump for our Coaches.

Looks to be a good US Source for our Water pump Supply stream and uses a
ball/roller bearing and all new components,,,,,,,,,,,,,,,,,but pricey.
