i need help again :)with air power hammer

[Valentin]

i instaled a power hammer a few days ago... and while i was getting it into the shop it droped on one side ...since then there is oil coming down the piston i thought that it was because when i was droped he oil went up and now it has 2 come down ..but ... i don't know ...any ideas ? is it normal lubrefiation ? or is it something broken....i used the power hammer for a while ...like 3 minutes all works fine but oil is leaking

[ApprenticeMan]

Ouch, that looks bad Valentin, I hope it can be fixed!

[Chris Pook]

What do you mean by dropped? as in it fell on its side with a big crash ? or just leaned over?


EDIT ******do not run hammer****** read the next post


Is it running fine, with the TUP retracting all the way back up and staying up at idle? is it running and hitting with a consistant beat?

If thats all fine, I would guess there was alot of oil sitting in the hammer.

Another thing could be your oiler pumping to much oil in, My oiler on my Nazel puts out a bit to much and I get oil dripping down the ram after its been used.

I just wipe it off with a rag and go back to work. I figure I'd rather have more oil than not enough

[Chris Pook]

i just looked at the photo's again.

DO NOT RUN THE HAMMER without the dies in or some sorta big block spacer.

you don't want the TUP to bottom out. could cause serious damage and could be contributing to your oil leak.

Are there any scribed lines on the TUP (the hammer shaft) near the bottom about an 1" or 2 fromt the bottom and probably 9" or so inches up? The upper line would be the farthest you want the the TUP to drop.

Valentin, don't know much about the problem you asked about. But... You're going to hate having it tucked in that corner once you try to work on longer pieces which I can see from the gate/fence panel in the pix you do work on. just my .02 worth.

[Fionnbharr (finn:-)]

Is this the first time you have run this particular hammer?

It could be normal lubrication... (I will pray for you that it is;-)

Did anything on the outside of the hammer get damaged?

As long as everything is running correctly I wouldn't worry too much...

If it is new to you, can you ask the former owner about this?

And Chris is right don't run the hammer without the dies installed.

It is a beauty, I hope 'she' is alright;-) How heavy a hammer is it? and who was the manufacturer?

And mcraigl is very right, you will want room around the hammer, so that you can work in the middle of long bars.

10x for the reply i instaled the dies and i never used it without them .The picture was taken way back...and yes the shaft is retracting all the way back when it is at idle speed and at (On position)
Yes all the controls got broken but weldet them on place
and the drop...was with a litle bang ...caz the hammer landet on dirt not concreet.
I don't know anything about who manufatured it ...the only words that are writen on the hammer is 1987 i guess this is the year when the hammer was made.
The hammer weights 3tons and has a 3phase engine 11kw with 6 belts...2day i poundet a little with it all seems to be just fine till now
When the piston is way up ...if i look inside the sleeve i can see it moving up and down ...but it does not get lower than the ...sleeve...how shooud i call it ...the black painted plate where the screws are inserted..

And i have one more question ....
What is this ??? in the picture -the small pipe with the cap- behind the big wheel ...shoud i put oil or vaseline ??? or is it for something else ?

[Kallsme´n]

The pipe should be filled up with oil, its for the lubrication for the bearing.
In my eyes it looks like a Beche´ hammer is that correct?
Its no problem to run the hammer.
When the hammer drops on the side, the oil is running in the cylinder and leaks out on the piston, its totally normal.
If it sound ok there is no problem to run the hammer.
The piston would hawe minimum of 10mm to its lower lever to run properly.
The hammer should have a good lubrication oil like cylinderoil,or a good
enginr oil to run smothley.
Hope you understan my english.

If its a Beche´hammer i have lots of litterature of them.

G'Day Valentin,
mate , was the shaft all the way down while youse was movin' it , ifin so youse may ave damaged the oil seal when it went " all fall down go BANG ! "
I'd be lookin' there first ifin youse still ave lot's of oil runnin' down shaft .

I used ta work in footwear industry & we had a 10 tonne clicking press ( for cutting out leather uppers for shoes ) we needed moved from 1 factory to another , the shaft was down as it was lifted off truck & a nuf nuf " helper " didn't place sling rite on it & it went over . They got it back to it's feet , all seemed ok , we installed it & turned it on , oil runnin' down the shaft from where the shaft crushed the seal , took us 3 weeks to find another 1 & replace it

I dont think It´s the oilseals leaking,
I will put up a picture of the hammer inside.
If the piston just dropped down to the lower position there is no thing to worry about.

What i can understand, you drop the hammer on the side? is that correct?
Than piston has nothing to do wiht this problem, and in my eyes,
i can not se a problem att all on the hammer.

I have work with this type of hammer nearly 30years as a blacksmith,
and repairer so i hawe lots of information and plueprints of this hammer.
