A Guide to Hydraulic System Maintenance and Service

metal services

Proper hydraulic system service is the key to reducing system failure and maximizing operating life. The small monetary and time investment into routine maintenance can help save you the cost of a new system. At Calgary’s Aaron Machine Shop, we provide comprehensive hydraulic service alongside our popular CNC machining services. We have put together a guide to keeping your hydraulic system in good shape and identifying problems.

Important Preventative Maintenance Tasks 

Hydraulic system maintenance is relatively simple and straightforward, and very effective at preventing component failure. Here are our top tips to keeping your hydraulic system in good condition:

  • Change the fluid and filters of your hydraulic system as often as recommended by the manufacturer.
  • While the system is operational, check the hydraulic fluid temperature. If it is too hot or smells burnt, then your cooling system may be faulty.
  • Keep the hydraulic system free of contaminants by keeping all of your fluid containers well sealed.
  • You can also prevent contamination when changing the fluid by cleaning the areas around the filters, fill plugs, and dipsticks before you remove them.
  • Check the oil levels and condition before each use. If the levels are inadequate, your pump can sustain severe damage. If the oil appears to have a foamy consistency, then there may be a leak in the system.
  • Inspect all hoses and lines on a regular basis for cracks, dents, or cuts. Ensure that the hose routing is correct and that flex points are not stretching or kinking.
  • Inspect the cylinder rods for signs of damage and check the cylinder housing for any leaks.

Types of Hydraulic System Failures

Familiarizing yourself with the different types of hydraulic system failures can help you spot signs of trouble early and get expert hydraulic service when you need it. There are three main types of failures to be aware of.

– Transient failure: A transient failure is characterized by symptoms that come and go. Perhaps the system feels hesitant one day because of momentary interference by contaminating particles, but the next day it seems to run better when the particles move. Any unusual system behaviour should be reported and inspected.

– Degradation failure: As a hydraulic system ages, its various components may see a decline in performance from either contamination or wear and tear. Any necessary repairs or replacements should be carried out promptly.

– Catastrophic failure: This is a complete system failure that usually occurs when signs of degradation and transient failures are ignored. Recovery is typically only possible with extensive and expensive repairs.
