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.

Northern tool buy the 14v one, my dad has it and likes it.

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.

If it works with this price

This is only 4.8 volt model but its listed for under $30. so if it works it will definitely be worth it. here is the link..

if the link is not working item# 95633-3VGA

and u may have to add flexible hose let me know your experience if u buy it

If you are going to get one get this one. We have the older 12 volt model and it greases on average a dozen or more trucks, trailers and reefers everyday in 90 to -40 degrees and has not failed yet. The only weak link is the hose as we have had to replace it several times in the last year or so. But this is in some pretty harsh conditions. You must get the hose for that gun as a regular grease hose fittings will not work. For the price it is one of the best buys.

I would ask for documentation on that statement from him if he meant to Purge ALL the old grease

You have me going now. (I hate having to think after work)

An average grease gun will put out 1 oz every 30 pumps.

So with your 100 pumps needed, lets say 3 oz of grease.

So the question is, what bearing hold 3 oz of grease in its bearing pack? Let's take a common manufacture like Browning. There roller bearings that hold 3 oz are 4 7/16-4 1/2. There ball bearings that 3 oz are.....nothing, there biggest at 4" is still at 1.5oz.

If you are working with 4 1/2", then I do appoligize. The biggest we really come across in 3" which only hold on average 0.85oz and we don't purge all the grease out of them.

I still don't see where it tells you to purge all the old grease of the bearing pack.

Me too ?

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.

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?

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.

You could get Pneumatic Grease Gun and use a nitro tank.

alemite makes a good one,pricy but thats the way it is check with your bearing supplier for info.

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
