Thread: Enerpac oil

Hi Michael, it would definitely pay you to check with the oil manufacturer. I have heard of people using generic hydraulic oil, and supposedly without problems, but I know that at a previous employer, they had trouble with seals when they tried other oils, and they ended up stocking Enerpac oil for that reason. If the Enerpac oil is not over the top price wise, I think that I would go that way, as you know you are using what the manufacturer recommends, and has designed for, so there will be less likelihood of any problems. Sorry for the fence sitting answer
Rob.

I use power steering fluid in mine ( enerpac press), for a couple of years now , with no adverse effects (yet),

at worse you are up for a seal kit if ithe Tellus doesnt agree with the seals

Fred

Generic ISO68 hydraulic oil...

Morris Lubricants ISO68 in our enerpac porta power plus 8 rams for 4 years. No problems.....yet

I repair Enerpac (and other brands) all the time. Any ISO 46 or 68 will be fine.

Never use auto trans fluid in hydraulics unless recommended by the manufacturure. It can lead to seal softening and failure.

i bet a high quality mineral hydraulic oil will do.

Just a bit of food for thought.
I have used different brands of oils many times, I am also aware that emergency services will not mix or change brands of oils [at least the one I work for]

Some people and companies stick to one brand for many differentreasons, product loyalty or someone told them it`s the brand to use. In one case it was prescribed by the insurance company. Most of it I don`t understand but that`s the way it is.
I don`t tend to mix oils, but sometimes in the field you have no choice.

I don`t know which of the many additives in the auto trans oil causes the problem. I was told years ago but it went out as quick as it went in.

It`s not a quick reaction, but over time the seals can become soft or even crumbly.

The old type F I would use if its all I had. (I imagine it would be hard to come by now). Its a very low additive oil compared to the Dextron range.

Toyota specify Type F atf (with the addition of a special toyota additive), for use in their skid steer loaders. Most of the loaders are converted over to use standard diesel engine oil because the pumps etc last longer using engine oil - possibly due to our warmer climate in Australia.
Atf thins down too much for my liking when warm.
Type F is still readily available from auto parts retailers and oil companies.
I guess the seal question relates to the type of seal used. If anyone has ever put a rubber seal designed for brake fluid into a bit of oil, then they'll know all about seal softening! The seals expand around 30% and are as soft as butter.
