Catalogue references associate it with select hydraulic systems used in equipment from Bobcat, Case IH, Caterpillar, Hyster, Ingersoll-Rand, John Deere, JLG, Kubota, Massey Ferguson, Sullair, Terex, and Yale, among others.\u003c\/p\u003e\u003cp\u003eSome WIX catalogue applications include Bobcat 631 and 641 equipment using the Deutz F2L 511 engine; however, the 51551 is listed there for \u003cstrong\u003ehydraulic filtration\u003c\/strong\u003e, not engine-oil filtration.\u003c\/p\u003e\u003ch3\u003eFitment Notice\u003c\/h3\u003e\u003cp\u003eConfirm the number on the existing hydraulic filter or verify the filter-head specification before ordering. The mounting thread, gasket dimensions, micron rating, flow capacity, and system pressure requirements must all match. Do not install the WIX 51551 as an engine-oil filter solely because its physical dimensions or thread appear compatible — this filter has no internal bypass or anti-drainback valve and is engineered for specified hydraulic applications.\u003c\/p\u003e\u003ch3\u003eWhen to Replace\u003c\/h3\u003e\u003cp\u003eReplace the hydraulic filter at the equipment manufacturer’s recommended service interval, or sooner when operating in dirty, wet, or high-load conditions. Replacement is also required when hydraulic fluid is changed, after a pump, cylinder, motor, or control valve failure, when contamination has entered the system, when hydraulic operation becomes slow or erratic, when the filter housing is dented, corroded, or leaking, or when a filter-restriction indicator signals excessive pressure differential. Always replace after major hydraulic repairs to prevent residual debris from circulating through newly installed components.\u003c\/p\u003e\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cp\u003eClean the filter head and surrounding area before removing the existing filter. Confirm the old gasket has been removed from the mounting surface. Lightly lubricate the new gasket with clean, system-compatible hydraulic fluid and install by hand to the manufacturer’s tightening specification — do not overtighten. After installation: restore the hydraulic fluid level, operate the system at low pressure, inspect for leakage, cycle hydraulic functions to remove trapped air, then recheck fluid level and filter after the system reaches operating temperature.\u003c\/p\u003e\u003ch3\u003eCross-Reference Numbers\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDonaldson P551551\u003c\/li\u003e\n\u003cli\u003eBaldwin BT839-10 \/ B958\u003c\/li\u003e\n\u003cli\u003eFleetguard HF6056 \/ HF6121 \/ HF6505\u003c\/li\u003e\n\u003cli\u003eFRAM P1653A\u003c\/li\u003e\n\u003cli\u003eMann W940\/38\u003c\/li\u003e\n\u003cli\u003eHastings HF731\u003c\/li\u003e\n\u003cli\u003eParker RH-20-10C\u003c\/li\u003e\n\u003cli\u003eCARQUEST 85551\u003c\/li\u003e\n\u003cli\u003eNAPA 1551\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eRelated WIX filtration options: \u003cstrong\u003eWIX 51552\u003c\/strong\u003e (approx. 20-micron) and \u003cstrong\u003eWIX 51553\u003c\/strong\u003e (approx. 33-micron) — not automatic direct substitutes; always match the required micron rating and hydraulic-system specification.\u003c\/p\u003e\u003ch3\u003eOther WIX Filters\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/wix-oil-filter-51806\"\u003eWIX Oil Filter 51806\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/wix-oil-filter-51629-lister-petter\"\u003eWIX Oil Filter 51629 – Lister\/Petter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/nsp-61\"\u003eWIX Oil Filter 51061 – GM Tall\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/nsp-64\"\u003eWIX Oil Filter 51083\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/nsp-69\"\u003eWIX Oil Filter 51361\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/nsp-70\"\u003eWIX Oil Filter 51365\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/nsp-71\"\u003eWIX Oil Filter 51515 – Ford\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003eThe important detail with the WIX 51551 is that it is a \u003cstrong\u003ehydraulic filter\u003c\/strong\u003e, even though it may be described simply as an oil filter in older inventory systems. Matching the filter-head thread is not enough — the 10-micron rating, flow capacity, and lack of an internal bypass valve must also suit the hydraulic system.
