I need hydraulic fluid recommendation for Lempco hydraulic press - tnx in advance
I need hydraulic fluid recommendation for a Lempco hydraulic press.
Off the label on the machine:
Lempco Products, Inc.
Bedford, Ohio
Series 600-A
Capacity 25T
"Fill hydraulic reservoir with:
Gargoyle DTE Light
or
MOBILOIL ARCTIC SPECIAL
or equal products of SOCONY VACUUM Co., NY, USA
Do not use hydraulic brake or shock absorber fluid or hydraulic jack oil."
I have tractor hydroil, don't know if that would be appropriate.
Many thanks for any suggestions about this.
Lawrence

Gargoyle is now Mobil. Mobil markets some refrigeration oils under the Gargoyle name, but I read somewhere (possibly a steam engine site) in the past that whoever it was that originally used the Gargoyle name was eventually acquired by Mobil. I think DTE Light is Mobil's ISO 32 hydraulic oil. Personally I can't see any reason why your universal tractor hydraulic oil wouldn't work fine. IIRC its an ISO 32 oil with the addition of some friction modifiers that benefit the friction material in wet clutches, but other than that, about the same thing as the 32 hydraulic oil.
Don't know whether its still the case or not, but as of a few years ago both Caterpillar and Grove (largest maker of hydraulic cranes) each had about a quarter page of specs and brands of acceptable hydraulic oils, and both concluded their oil spec by saying SAE 10 wt NON-DETERGENT motor oil was fine too for use in their systems. -

Thanks a bunch. mebfab suggested hydroil too but I just wanted to make sure. Originally Posted by metlmunchr

I'll go ahead and use the hydroil.
Another question:
There are 4 sets of holes, each for pins to hold the platform at the desired height. Only two were there when the machine arrived. I was thinking it would always be a good idea to use 4 pins rather than just the two I currently have.
I was actually going to use 2 grade 5 bolts with nuts for the extra two as the frame torques a bit from age and wear during use.
Thanks again for the response.

I'd add the other 2 pins too. I've got an 80 ton Nugier shop press and back when I got it there were only 3 of the 4 pins. I made one up for the 4th hole just to be safe.
If yours is air over hydraulic you might want to clean and flush the system out too. Mine started leaking past the ram seal a while back. Got a kit for it and when I tore it down it had the awful-est mess of glop in it imaginable. It uses shop air pressure on the top of the oil reservoir as a rapid down and then uses the pressure intensifier to jack up the force. I think the shop air on the oil reservoir over the years had deposited a lot of water in the oil. Nothing rusty though, but man what a mess to clean out. -

Hydraulic oil
I think the tractor hydraulic you have would be just fine, I use it for all the hydraulic fluid needs that I have ( jacks, press, backhoe, motorcycle chaincase, etc)

I will do that. Probably will use bolts which will tighten up the frame and add rigidity. Originally Posted by metlmunchr
