Q: What are the specifications of the CR 90730 oil seal?
A: The CR 90730 features an inner diameter (ID) of 60.33 mm, outer diameter (OD) of 88.89 mm, and a width of 9.4 mm. It is a nitrile hydraulic seal designed for oil retention.
Q: What is the purpose of the CR 90730 nitrile seal in lift truck applications?
A: The CR 90730 is designed to prevent oil leakage in rotary shaft assemblies found in electric lift trucks. Nitrile material provides resistance to mineral oil and maintains sealing effectiveness across typical operating temperatures.
Q: What are the cross-reference and alternate part numbers for the CR 90730?
A: The OEM part number is CR 90730. Alternate manufacturer part numbers include 090730, CR090730, and cross-reference CRN-090730. These are all valid references for this seal.
Q: How do I know if the CR 90730 seal needs replacement?
A: Signs of seal failure include oil dripping or leaking from the drive axle or motor assembly, visible oil residue on equipment surfaces, or a change in equipment odor. Low oil levels on repeated checks also indicate potential seal leakage.
Q: Is the CR 90730 compatible with different types of hydraulic oils?
A: Nitrile seals like the CR 90730 are compatible with standard mineral-based hydraulic oils used in Crown lift equipment. If your equipment uses synthetic or alternative fluid types, verify compatibility before ordering.
