Frequently Asked Questions
Q: What is the RA 939-001 oil seal used for on Raymond electric lift trucks?
A: The RA 939-001 is an oil seal component for Raymond electric lift truck assemblies. Oil seals are critical for preventing lubricant leakage and contamination in rotating shaft, bearing, and motor assemblies.
Q: Which Raymond electric lift truck models use the RA 939-001 oil seal?
A: The RA 939-001 is designed for specific Raymond electric lift truck models. Identify your equipment serial number and model to confirm compatibility, as oil seal sizes and types vary across different assembly locations.
Q: What material is the RA 939-001 oil seal made from?
A: Oil seals are typically constructed from nitrile rubber or similar elastomer materials with a spring-loaded metal garter or retainer. The nitrile material resists petroleum-based oils and maintains flexibility across operating temperature ranges.
Q: How often should the RA 939-001 oil seal be replaced?
A: Replace the RA 939-001 when oil leakage appears around the sealed shaft, when the seal shows visible damage or hardening, or during scheduled maintenance intervals. Rubber oil seals typically remain effective for 3 to 5 years depending on temperature, oil type, and shaft speed.
Q: What signs indicate the RA 939-001 oil seal needs replacement?
A: Replace the seal if you observe oil dripping or pooling near the seal location, if the rubber appears cracked or hardened, if the seal spring has lost tension, or if operating temperatures have caused thermal degradation. Leaking seals allow lubricant loss and introduce contaminants.
