Installation decomposition diagram
Identification: Use the machine's service manual and kit packing list to identify the correct seal for each specific location.
Cleanliness: Clean all sealing surfaces meticulously. Remove old gasket material and any debris.
Inspection: Inspect mating surfaces and shafts for scratches, nicks, or wear that could compromise the new seal.
Proper Selection: Use the correct seal material (e.g., FKM for fuel, NBR for oil) and size for each application.
Lubrication: Lightly lubricate O-rings and lip seals with clean hydraulic fluid or oil before installation.
Careful Installation: Use proper tools to install lip seals squarely. Avoid twisting or cutting O-rings.
Torque Procedures: When reassembling covers or flanges, use a torque wrench and follow the specified tightening sequence and values.
