Filters have a very important role to remove harmful contaminants, whether from a lubricating oil circuit, hydraulic system, transmission or compressor etc, that would otherwise cause internal damage. How the filter is installed is critical for it to function properly. Proper filter installation can be overlooked, or misunderstood. The installer may have fitted a lot of filters over many years, but improvements to material and manufacturing processes affect how filters are installed today. These installation instructions are designed to assist with current and correct method for spin-on type filters.
These steps below are important guidelines that must be adhered to.
A. Should the installer not install as per instructions on the filter, warranty consideration for an incorrect installation may be denied. In reviewing the main sealing gasket the manufacturer (using various analytical techniques) can discern things such as how much tension the seal received when it was installed.
B. If a strap tool has to be used to tighten a filter, ensure the tool is positioned closest to the base plate or manufacturing seam. Any other position is likely to damage the filter and create a leak.
C. The only variation to the installation is where the manufacturer makes it clear as to how much to turn (tighten) the filter after the gasket has contacted the base. (See Step 4) Certain filters require a different amount of tension to another. Always read and follow the installation instructions on the side of the filter.
NOTE: This information relates to all spin on filters in various applications. For example: oil, hydraulic, transmission, final drive, cooling system, breather, compressor, fuel, fuel/water separator, bulk tank or anywhere spin-on filters are used.
