What do you folks use to lubricate your jacks? We've had the MH almost 3 years, and this is the one area I have not delved into yet, but need to. My jacks are hydraulic PowerGear.

WD40. I spray my Power Gear jacks about every six months.

Been doing that for 14 years with no problems.

The fluid that you use for the pump. Keeps the seals lubed.

WD40 is the “go to” product for cleaning the levelers.

Our Hydraulic jacks had grease fittings but the manual said nothing of what to use in them.It said to spray and wipe down the rams while extended with silicone.
I use or rather where we stored it used about 20.00 a tube lithium grease that you can never get off your hands.I have some in the lawn equipment garage but hurt my knee and don't feel up to hobbling out there. The price doesn't matter, just get the best you can find in grease in oil and women. The last one chose me and she is still ticking just great and no oil or grease required.

I have used WD-40 but I prefer silicone. WD-40 is a good cleaner and protectant from moisture but it is not a very good lubricant.

This. There is a reason nothing is listed in the manual - it's not recommended.

As noted many times before, anything you put on the rod simply attracts dirt and grime. The wiper, when in good condition, cleans that grime off when the rod retracts. Enough grime and eventually that wiper gets worn and all that junk now ends up in your hydraulic system. Nothing good happens when junk gets in your hydraulic system.

And yes, as part of my real job I deal with hydraulic cylinders and systems on a regular basis, as well as pneumatic cylinders and systems. There are cylinders in our shop every day of the week.


There are 24 hours in every day - it all depends on how you choose to use them.

Depending on the year model for your Powergear Hyd jacks. OLDER at least over 20 years have NO grease Zerks at the bottom of the cylinder. Jacks newer or rebuilt with the Powergear rebuild kit will have a grease Zerk on the bottom of the cylinder just above the footpad. THIS Zerk you install standard lube grease until the cylinder seal just starts to bulge. This grease will usually fix any
slow or sticking retract problems on Powergear HYD jacks. Other than this, just keep the inner cylinder clean and shiny. Doug

Video at 1 minute 30 seconds shows the Powergear Zerk.

Thanks everyone! I'll have the MH here next weekend to begin the spring wax job, so in addition to changing the oil and filter in the genny I'll look at the jacks. It's a 2006 National SeaBreeze, so based on Dougs comment I probably have the Zerk fittings.
