Frequently Asked Questions
Q: What is the CL 908552 shaft oil seal used for?
A: The CL 908552 is an OEM shaft oil seal for Clark electric lift truck applications. This seal is installed on rotating shafts in hydraulic pumps, motors, or transmission assemblies. The seal provides reliable fluid retention to prevent leakage while excluding external contaminants such as water, dust, and salt spray from entering the shaft cavity.
Q: Which Clark electric lift truck models use the CL 908552 seal?
A: The CL 908552 seal is compatible with Clark electric pallet jacks including model PMX 45 and PMX45. The seal fits specific shaft diameters in hydraulic and drive assemblies. Verify your truck model, shaft diameter, and seal cavity bore diameter before ordering. Cross-reference your equipment documentation or measure the existing seal to confirm fitment.
Q: What material options are available for the CL 908552 seal?
A: The CL 908552 is available in multiple elastomer materials including nitrile, Viton, and Teflon. Nitrile is the standard choice for mineral oil hydraulic systems. Viton offers superior temperature and chemical resistance for high-heat applications or synthetic fluids. Teflon provides extreme low-temperature performance in cold storage operations. Select material based on your fluid type, operating temperature range, and environment.
Q: What is the difference between single-lip and double-lip configurations for the CL 908552?
A: Single-lip seals retain pressure on one side of the shaft while excluding contaminants from the other side. Double-lip seals provide dual protection by retaining fluid on one side while excluding contaminants on the opposite side. Use single-lip configuration when pressure exists on only one shaft side. Use double-lip when both fluid retention and external contamination exclusion are critical.
Q: How do I diagnose a leaking CL 908552 seal?
A: Symptoms of seal failure include oil dripping from the shaft area, visible oil staining on external equipment surfaces, or reduced hydraulic fluid levels without visible external leaks. Inspect the shaft for scoring or corrosion which indicates seal failure. Do not attempt to re-tighten or adjust the seal. Replace the seal assembly per Clark engineering specifications to restore fluid containment and prevent equipment damage.
