Frequently Asked Questions
Q: What does the DF157 seal and washer assembly fit?
A: The DF157 is a D157 seal and washer component for Noblelift model DF55 pallet jacks. This part prevents hydraulic fluid leakage and protects internal components. Confirm model compatibility before ordering.
Q: What is the purpose of the DF157 seal and washer?
A: The seal prevents hydraulic fluid from leaking at shaft connection points. The washer distributes load and protects the seal from damage. Together they maintain system pressure and prevent contamination of internal hydraulic circuits.
Q: What are signs that the DF157 seal is failing?
A: Watch for hydraulic fluid leaks near the mast connection points, a soft or spongy response when raising the load, or visible wetness around the shaft. A failing seal allows internal contamination and causes loss of hydraulic pressure.
Q: How long does the DF157 seal typically last?
A: Seal lifespan varies with use frequency, environmental conditions, and hydraulic fluid condition. Regular hydraulic fluid changes and inspection every six months will extend seal life. Replace the seal at the first sign of leakage.
Q: What hydraulic fluid works with the DF157 seal?
A: Use the hydraulic fluid grade specified in your Noblelift DF55 manual. Incompatible or contaminated fluid degrades seals prematurely. Maintain proper fluid level and replace per manufacturer recommendations.
