filling up greenlee hydrolic hand punch

[101010]

Does anybody now how to refill a greenlee hand punch with hydrolic fluid?

[ohmhead]

Well you look for your filling bolt on it then you only pour in greenlee fluid dont use any other type it will ruin the seals inside . just enough not all the way spilling out of the top say 1/4 inch below opening . Before filling release pressure ! take care its easy

Go to the greenlee site and download the manual. Go here (http://www.greenlee.com/manuals.shtml) and just type in the model number

where are the filling bolts located? What kind of tool do you use to fill it?

So Greenlee uses custom made seals that disintegrate with the use of 'normal' hydraulic fluids? :grin:

IMO it is a crock in order for Greenlee to sell high priced "Greenlee" fluid. If it was my own tool I would use almost any 10 weight petroleum product.

What is the model #

The Greenlee hydraulic punch that I have has a cap at the end of the cylinder that just screws off. You pour your fluid in, screw the cap back on, and you're good to go.

Mine has that too, thats all you have to do? Can I use fluid from Home Depot?

Well we dont agree with it but our tool room says it must be greenlee fluid kinda like the 881 benders so if you have lots of greenlee tools its a factory req fluid or your out of warranty your choice? take care

[nakulak]

Don't forget to fix the leak.

But we are not talking about a $7K 881 are we? :smile:

I believe it is against the law for them to terminate the warranty just because you used another product. The car makers have tried that and lost.

Well we use to sae wt hyd fld in most tools years ago but everyones so high tech today and correct its funny i use to work for a company that made there own tools tuggers , wire feeders, and there own mandrels made from old used tries cut with say 3 or 4 inch hole saw and strung on a stainless steel cord just attach to a pull rope cleaned and swabbed out the conduit better than the greenlee high tech pipe mandels they have now and no damage to the conduit or getting stuck . take care

Not sure but in that case your violating a code rule as well.

Would you say taking your truck to a local service station for non OEM brakes voids your vehicle warranty?

I agree with Bob, the mfg. want you to be intimidated into using their higher priced supplies for the equipment. When in fact the same fluid is produced under many name brands and depending on what name determines the price for the exact same product.
This past fall my son and I were in a farm supply store, he wanted to pick up a salt block for deer hunting. In the nice hunting supply display they had 1lb blocks of salt nicely wraped with plastic with pictures of deer on it. $10.00. I told him to follow me, we went to the rear of the store where the cattle supplies were, picked up a unwrapped 50lb block for $7.00. It's all in the packaging.

Good call. HD sells #10 screws for $5/100 in the fastener section. In the electrical section you can buy a kit of the same screws and plastic inserts and a concrete bit and a box for $5/100.

Same story with meyers snow plow pumps. They must get their seals from the same place. I wonder if I can put my plow fluid in my greenlee?:D

Ok the model I have is 767 I unscrewed the top poured in the fluid . nothing.. There is a screw inside that says bleeding . Try turing it in both directions . nothing . What am I doing wrong?

[rt66electric]

If i rememeber right---. Unscrew the cover off the end, ( be careful it might explode like a grease gun and splatter all over the place?) inside the cylinder there is a piston. Remove the external turn knob and bleeder plug located near the handle pivot(relieves the vacume lock). Look inside the cylinder remove the bleed screw on the piston, Use all-thread or wire to pull the piston out of the cylinder, be carefull not to scratch the walls. Fill the cylinder with HYD fluid(any brand will work -its not that complicated-). Re-insert the piston and internal bleed screw. Re-install the external turn screw and bleeder plug and bleed off the air.. Good-To-Go, untill another quart leaks out. The 767's are like old HARLEY DAVIDSON's ,If it don't leak oil-then its empty.

remove the other end

[jrannis]

Unscrew the knob that you use to let the pressure on and off of the knockout pump.
Get hydraulic fluid in the quart bottle that has the spout on the end like an old ketchup bottle.
Have your helper pump the handle while you hold the end of the bottle tight against the hole squirt the fluid in the hole. you will develop a rhythm, its a messy process but it works.

i don't know that greenlee hydraulic fluid is much of a price difference from
regular, or irregular hydraulic fluid, but the main thing is that you aren't using
dot 3 BRAKE FLUID, which is what most of us will do, as you can get a pint
anywhere, and it's cheap. mixing some types of hydraulic oil with brake fluid
will form this gummy product that won't damage the seals, but it'll build up
on them so they won't seal, and the thing will leak like a sieve.

friend of mine, long time ago, changed the fork oil on his KTM, and put in
dot 3 brake fluid. claimed it would work fine. it mixed with the silicone
fluid that was left in the fork leg, and gummed up the check valves.
this was discovered halfway thru the first day on the greenhorn enduro,
which at that time was a 500 mile event. his 11" travel forks went to 1/2"
travel forks, and in the mojave desert, that's not a pretty sight. neither was
trying to ride a 2 day, 500 mile event standing on the pegs.....

Well heres something greenlee doesnt tell you one must do for better pressure release the air inside the hose and tool get the air bubbles out it works better ever notice it bleed back a little or it takes lots of pumps to punch get the air out it works better we do it on our benders also on every refill . just like bleeding your brakes on that old chevy . take care
