Frequently Asked Questions
Q: What is the 3EC-01-32670 grease fitting used for on manual pallet jacks?
A: The 3EC-01-32670 is an interchangeable grease fitting designed for manual pallet jack pivot points and wheel assemblies. It allows technicians to inject lubrication into bearing and articulation points to reduce friction and extend component life.
Q: What are the thread specifications and maximum pressure rating?
A: The 3EC-01-32670 features a 1/4-28 UNF thread size and a maximum working pressure rating of 6,000 PSI. These specifications ensure compatibility with standard grease gun fittings and reliable performance under normal lubrication conditions.
Q: What material is this grease fitting made from?
A: The 3EC-01-32670 is constructed from case hardened steel with a minimum hardness rating of Rockwell C30. This material composition provides corrosion resistance, durability in warehouse environments, and reliable sealing under lubrication pressure.
Q: Which pallet jack brands and models are compatible with the 3EC-01-32670?
A: The 3EC-01-32670 is compatible with manual pallet jacks from Crown (cross reference 370159), Toyota (cross reference 00590-03570-71), and Lift-Rite equipment (cross reference LF 27662). These cross references confirm fitment for systems with 1/4-28 UNF threaded pivot and wheel assemblies.
Q: How often should grease fittings be lubricated?
A: Manual pallet jack grease fittings should be lubricated every 50 operating hours or weekly if the jack is in regular use. Apply grease until a small bead appears at the fitting to ensure adequate lubrication of bearing surfaces and pivot points. Over-greasing can cause fluid to migrate into seals and reduce their effectiveness.
Q: What happens if grease fittings are damaged or leaking?
A: A damaged grease fitting allows lubrication to escape and permits contamination and moisture entry into bearing assemblies. This leads to accelerated wear, rust formation, and eventual bearing failure. Replace damaged fittings immediately to prevent component damage.
