Compatible With
The Hydro-Gear 56144 Lip Seal is used in select Hydro-Gear hydraulic and transmission assemblies, including:
-
Hydro-Gear integrated transaxles and hydrostatic pump/motor systems
-
OEM parts diagrams and rebuild kits that specify a 1.375″ × 2.75″ × 0.500″ seal
-
Applications where robust shaft sealing is required
Note: Always verify compatibility by matching the seal dimensions to your Hydro-Gear component’s specification before ordering.
How It’s Used
This lip seal is installed internally where a rotating shaft passes through a housing bore:
-
Prepare System: Drain hydraulic fluid and clean the work area before service.
-
Access Seal Location: Disassemble the transmission, pump, or motor housing per service manual.
-
Remove Old Seal: Carefully extract the worn seal without damaging the housing bore.
-
Inspect Surfaces: Check shaft and bore surfaces for wear or scoring; repair as needed.
-
Install New Seal: Press the Hydro-Gear 56144 seal squarely into the bore using the proper seal driver.
-
Reassemble & Refill: Reassemble components, refill with appropriate hydraulic fluid, and test for leaks.
Correct installation ensures effective sealing and reliable operation.
Suggested Maintenance
-
Inspect around seal areas periodically for signs of seepage
-
Maintain clean, correct-grade hydraulic fluid to reduce premature seal wear
-
Replace seals whenever related drive components are disassembled
-
Avoid sharp tools that could damage sealing lips during service
-
Use only OEM-spec Hydro-Gear seals for proper fit and long service life
