Heavy Earthmoving and Quarry Work
Operating in abrasive, dust-laden environments challenges any hydraulic system. This 90 µm wire mesh filter stops larger particles before they can score cylinders or degrade valve performance. The robust mesh media resists collapse under high pressure differentials, keeping your Caterpillar equipment running through the longest shifts.
Scheduled Maintenance Programs
When you service multiple hydraulic machines on a calendar or hour-meter basis, bulk-purchasing identical filters cuts administrative time. The SPM-HYD-1904 crosses over to many brand-specific part numbers, letting you stock one SKU that fits Caterpillar and other machinery using this element. Less shelf clutter, faster change-outs.
Mobile Plant with Frequent Attachment Changes
Quick-couplers and attachment changes introduce contaminants into hydraulic circuits. The out-to-in flow pattern captures debris before it reaches sensitive downstream components. Fitting directly into the existing filter head via 1.1/4 inch NPT threads, it can be swapped out in minutes during routine attachment checks.
Mixed-Fleet Operations
Combine harvesters, loaders, and material handlers from different OEMs often share common hydraulic filter formats. This element’s cross-reference list includes Can Flo, Flow Ezy, Gresen and Zinga, meaning one filter part number can service several machine brands. Consolidating inventory simplifies reordering and reduces the chance of stocking the wrong element.
The SPM-HYD-1904 is a direct replacement for the hydraulic return-line filter used in many Caterpillar machines. It fits housings that accept a 99 mm outer diameter element with a 1.1/4 inch NPT female thread. Because we cannot list every specific model, check your existing filter’s dimensions and thread against our specifications to confirm fitment.
This element uses wire mesh media rated at 90 µm. Wire mesh is reusable and resists collapse under high flow and pressure spikes, making it suitable for return-line filtration in hydraulic systems where contaminant loading varies.
The total height is 141.5 mm and the largest outer diameter is 99 mm. The thread is NPT 1.1/4 inch female, and the largest inner diameter is 70 mm. Flow direction is out-to-in. Compare these measurements with your current filter to ensure a correct physical fit.
No, it is an aftermarket part designed to match the OEM specifications for fit and filtration performance. It is not manufactured by Caterpillar but is built to the same dimensions and media rating, offering a cost-effective alternative. A 30-day money-back guarantee and a price-beat guarantee provide peace of mind.
Installation follows standard hydraulic filter replacement procedures. First, depressurise the hydraulic system and clean the filter head. Remove the old element, lubricate the new O-ring with clean hydraulic oil, and thread the SPM-HYD-1904 into the housing hand-tight plus a quarter turn. Always check for leaks after restarting and top up fluid as needed. Consult your machine’s service manual for torque values.
We ship worldwide with tracking on every order. All Spare Part Mart aftermarket filters come with a 30-day money-back guarantee for your confidence. If you find a lower price for an identical aftermarket element, our price-beat guarantee ensures you get the best deal.
