    Cordless Grease Gun

    We do alot of work on cooling towers and mechcanical systems and one of our issues is greasing the fan shaft bearings.....the manufacturer suggests greasing by pushing out the old grease with the new grease. Makes sense, problem is that we have to safely climb to reach the zirk fitting (installing extension lines this week) and we currently have a manual/hand pump grease gun. Does anyone have any experience with a cordless/battery grease gun? Are the reliable? Do they pump a decent amount of grease?
    Thanks in advance for any information!

    Also, if this is in the wrong forum topic please let me know.

    Thanks, Nick

    We grease 4 times a year, as per our contracts. Normally it takes 2-5 pumps to start pushing the grease out of the bearings, depending on the size. I just can't see spending that much for a battery gun, when I can just pump a few times for $25.

    Also have you considered automatic lubicators. They are great in very hard to reach areas. We have some equipment it takes about 30 minutes and a 40' extension later to get to the top bearings. With the automatic, we only need to replace it once a year.

    What kind of bearings are you greasing? What kind of gun are you using that only takes 2-5 pumps? We are greasing fan shaft bearings on BAC cooling towers and with a hand grease gun we are having about 100pumps to push out the old grease. We have small auto lubricators but they only allow 10 feet of extension which only allows us to mount the units on the top of the tower. Checking these on a regular basis because time consuming and at $80 per refill kit makes this very costly.

    Long story short, the manufacturer recommends greasing semi-annually but our bosses bosses wants us to grease monthly (ok'ed by the manufacturer) which means the auto-greasers no longer an option due to cost.

    I guess I misunderstood. If you feel that that all the grease in a bearing pack needs to be replaced on a monthly basis, then I don't know what to tell you.

    I would love to see BAC's literature that says that there bearings need their bearing packs to be fully replaced with new grease on a semi anual basis.

    What I was referring to, was we push about 1/8" of grease out of the bearing pack on a quartaly basis. We don't push the entire grease charge out.

    Maybe I wrong?

    You could get Pneumatic Grease Gun and use a nitro tank.
    Karst means cave. So, I search for caves.

    Talking plews

    If you go to ebay and type in Plews cordless grease gun, you should get a couple of mathes. I bought one of these a couple of years ago and this thing works great. Has saved me many of times.

    Remove the alemite fitting from your grease gun.Throw the hose or bent pipe that came with the gun away. Get in black pipe two 6", one 2", one 3" inch nipple, one coupling and two 90's

    Assemble six inch nipples together with coupling, next thread 90', 2" nipple, 90', and 3" nipple. Thread the Alemite fitting on to the end of the 3" nipple. Thread assembly onto your grease gun. You now have an assembly you can turn & twist to grease almost any fitting, using one hand. Also with it turned so it forms an upside down "U" a hanger for your grease gun.
