How to Care for Your Hydraulic Inventory

Hydraulic components are expensive and, so, regardless of the amount of spares that you carry, one thing you want to make sure of is that your inventory is not deteriorating in storage. With this in mind, here are a few pointers for the effective long-term storage of hydraulic components:


1、Store them indoors in a clean, dry area.

This is stating the obvious and is easy enough to do for more compact components like pumps, motor and valves. But in the case of large or long cylinders, the warehouse department may find it more convenient to store them outdoors. This should be avoided if at all possible.


2、Protect all exposed metal parts.

Smear the internal surfaces of cylinder eye/clevis bushes or bearings with grease. Pump and motor drive shafts should be wrapped in oil-impregnated tape such as Denso tape. The same goes for exposed chrome on cylinder rods. Before applying Denso tape or a similar product to a cylinder rod, make sure that the rod is fully retracted. If a product like Denso tape is applied to the rod when the rod is not fully retracted, subsequent retraction can result in damage to the rod seal.


3、Plug the component’s port connections with steel (not plastic) plugs or blanking plates.

Plastic plugs don’t provide the same sealing integrity as their metal counterparts and are easily dislodged – both of which can result in contaminant ingression.


Consider filling the component with clean hydraulic oil through its service and/or case drain ports – particularly if it is an expensive, large-diameter or high-pressure pump, motor or cylinder.


In the final analysis, taking proper care of your spare hydraulic components is very similar to caring for the ones on your machines: Keep them clean, dry and cool!
