Frequently Asked Questions
Q: What type of grease fitting is SKU 00591-01416-81 and what size is it?
A: This is a push-on or press-fit grease fitting designed for Toyota lift truck lubrication points. Verify the thread size and body diameter against your equipment schematic to ensure proper fitment. Improper sizing can cause leakage or disconnection from grease gun connections.
Q: Which lift truck component locations typically use this grease fitting?
A: Grease fittings are installed on mast bearings, load wheel bushings, tilt cylinder pivot pins, fork carriage wheels, and steering components. The specific location depends on your truck model and configuration. Consult the lubrication chart in your operator manual for the correct fitting locations.
Q: How do I replace a damaged or worn grease fitting?
A: Remove the grease gun and gently unscrew or pull out the old fitting by hand or with pliers. Clean the threaded bore or hole with a wire brush and dry cloth. Install the new fitting hand-tight first, then add one quarter turn with a wrench. Do not overtighten as this can crack the fitting.
Q: What grease gun pressure is safe to use with this fitting?
A: Use a standard hand-operated grease gun with a maximum pressure of 5000 to 6000 PSI. Apply short pump strokes until grease appears at the bearing seals. Do not force excessive grease into the fitting, as this can blow out seals and create hazardous conditions. One shot per fitting per lubrication interval is typical.
Q: How often should grease points be serviced on lift trucks?
A: Lubricate grease points every 250 operating hours or monthly, whichever comes first. High-temperature or dusty environments require service every 100 to 150 hours. Use only lithium complex or multipurpose grease rated for material handling. Replace fitting if it cracks, leaks, or resists grease pressure.
