Oiler metering experiences:

I thought I'd share and get opinions:
After receiving an order of Trico brand replacements
assortment for a BP seriesII, I planned to dig
in this weekend and get dirty.
I ordered an assortment of 1 each of the
5/16(-24tpi)to1/8(#0flow) meters and 5/15to5/16(#0flow)
and both types of tube collars, and tube nuts, and
some 1/8 nylon tube. The 5/15to5/16 ended up being
the one I needed and by luck, the other meter fit my
grease gun so I drilled out to make a power flush unit
using the grease gun( another group members idea ).
I unconnected the tubes after the meters and
used the greasegun to pump lube into the lines and
checked for way lube seeping onto the respective way surfaces.
Only one surface seemed to be somewhat clogged and it opened up
after a few more pumps of the greasegun. I found that I had multiple
pressure leaks in the connection of hoses to each of the axis and
the Z azis jack. I used the original clogged meter as a plug to
isolate the flows to the different paths into the knee,table,etc.
The mill has a pressure gauge on the side, so I was able to see any
leakage of pressure after working on a section. After working on the
knee jack, lower table lube points, and upper table, I could get the
pressure up to above 100psi if I pressed the lube knob manually,
then the pressure would slowly decrease over time, and I observed a
nice flow of oil on the each of the ways(over time). I also observed
the metering units open ended to make sure a drop of lube came out
under pressure and over time.
The lube pump is an automatic Bijor that had a 1-2 hour cycle time.
I replaced the timing motor in it with a DC gear motor that I can
control to give a cycle time down to ~20seconds, or as long as I
like. This way I can cycle it on demand. Without manual assistance,
the pressure averaged about 60psi. If I press on the
pump knob I can bring it up higher for startup too.
Do these numbers sound right to others who have similar systems?
