I ran oil till it started to leak, shortly after a rebuild. I now run red grease. I put one zerk on and ran it till it comes out the other, than the other side till same . I then put a plug in the other and give it a couple more to make sure its getting to the spot. I have been doing this for years.

I am not going to vote but I think Tom @ JBP had the best idea! Reason being I have tried grease, 90 wt gear oil and 30 wt oil. As already stated it is a water invironment that doesn't get grease hot enough to flow( as a matter of fact ) I have seen it create a vortex effect and move away from areas the needs lube. If all seals are good and you check level regular,the oil bath system seems to work best. I would recommend using the designers specified oil and check OFTEN. If you pull both fittings and blow into one and watch the other you will know real qwik if the seals are allowing water in and also if the amount in the resevoir is full enough. M

you might want to read the engineering aspects of this bearing

http://www.sd-bearing.com/glk-dudx.pdf

i had the book (much easier for me to read)...but this is what i got from it:

1. good surface finish on the shaft is paramount
2. shaft hardness has a great effect (thus the chrome coating)
3. Works good with water, better with oil
4. Contamination is a big factor (as one would expect)
5. It has a definate life expectancy, and accurate visual indicators

my personal experience with the berkely bowl

1. joke, bad one
2. water tends to displace the oil (it is heavier)
3. If you pressure test it you blow out the seal (good seal, but very flexible)
4. Can be modified for two seals with a dremmel
5. two seals still aint good enough
6. AT got it better.

my advice:

1. Replace the relatively cheep tail bearings frequently
2. Replace the relatively inexpensive bearings frequently
3. Replace the tail bearings frequently or suffer a lost pump

oh yeah, GN7: is this the same tech they are using on the HP roller lifters? (sleeves rather than roller bearings)

and furthermore...you ever use WS2?
