I was looking online for information on greasing these aftermarket Oregon 82-325 Cast Iron Spindle replacement for Scag 46631 spindles, and I found a lot of conflicting information as to the construction and the corresponding greasing schedules for Oregon spindles. Most said all of Oregon's spindle bearings are sealed, so they only need a tiny bit of grease just to keep water out, that anymore than that is a waste of time and grease. I looked at Oregon's technical specs and found nothing on my specific spindle, so I contacted Oregon with my questions and they responded. Keep in mind that this reply strictly only concerns my Oregon 82-325 Cast Iron Spindle replacement for Scag 46631 spindles
They responded:
1) The bearings are not sealed (this may change to “sealed bearings in the very near future), and require greasing every 40 hours or once a week.
2) This lubrication process will grease the shaft at the same time.
3) See question/answer #1
4) You should use Lithium MP White Grease 2125
5) Pump grease into zerk fitting until fresh grease is seen coming from the “weep” valve (opposite side of the zerk fitting).
The bearings are not sealed, but the spindle shaft has a seal top and bottom.
The bearings (2) are tapered roller bearings with a cup and cone facing each other on the spindle shaft.
Grease the Oregon replacement spindle the same as a Scag OEM spindle which is the same as their response.
