    Honesty fellas, im the type that should invest money into mobil and other oil companys. I always I mean ALWAYS use excessive oil. I don't believe in over oiling the ways or bearing surfaces. So I know I will be good to go with just the zerks. I just wanted more... I am a man... what do you expect?? lol. If I get a machine, I cannot rest until its atleast taken apart enough to know that its lubricated correctly and not steel on steel friction.

    The larger point, either system, is when you lube..........
    periodically check as well, for evidence that each region is still getting any lube.

    Have you ever noticed where the BiJur pump is located on a Bridgeport and where the manifold is attached? Pump lower then the oil points or oiled spots. It is a pressurized system and the small brass fittings regulate or meter out a predetermined amount of oil to the oil spots. The manifold is lower then the saddle lube points accept the lower Y brass nut. But the others are lower and as the oil flows out of it there is a "head" of oil. Several machines especially old one's used the manual grease gun that is filled with oil to lube the ways. They stopped that in 99% of all machine in the late 60's. A good pressure lube system has a gage so you can observe the pressure build up and slow flow out and gradual pressure relief as the oil feeds out. On most of the newer machines have a pressure switch with an alarm that tells you when to refill tank or lower pressure that would tell you there is a hole or break in a line. If you use the grease gun be sure you oil all the zerks and don't forget the one under the what ever.....lol.. Rich

    If it's metered, then I stand corrected!

    Yer still better off leaving the wells with point-of-use lubing.
    Each point will be get's it's dose that way.

    Probably.. BUT... you might have to drill the Wells in all the right places and use new tubing.

    Personally... I start with new and leave the old on the BP. Around $200 and a day or more last time I did one.

    ok,well would it work if I took the complete system off cleaned it out and put it on the index mill just the way it came off the Bridgeport?

    Yep, definitely metered, and the fittings are not cheap, but much cheaper than galled, oil starved surfaces.

    The Bijur is not a metered system, it's a distributed system.
    And it approaches superstition, to think that all points will get
    an apportioned daily dose of lube from a plunge or two on the Bijur.

    Especially on an older machine, an open path may take 80%
    of the plunger's out-put and another point get nothing at all.

    It used to be that Monarch had the best prices on Bijur meters, http://www.monarchlathe.com
    They dont change the price of a part until they sell out and have to order more so certain prices are up to decades old.

    ok thanks, I do have a new cheaper Chinese pump, just not the metering unit and fittings, the new owner of the mill doesn't know it ever had one on it, that's why I was thinking of keeping it. it would make no difference to him. if its not worth messing with, its not worth messing with! thanks for the info!

    I would just get new parts and install that. You will want new flow valves anyway. And you can run plastic tubing instead of copper which will make life easier. It kind of looks like there was a system installed on it before. Maybe the old one got plugged up and they pulled it off to clean and never got any further.
