Frequently Asked Questions
Q: What is the rated load capacity of the 00591-37866-81 axle assembly?
A: The 00591-37866-81 is rated for up to 30,000 lbs load capacity at 30 inch load center. This rating assumes proper weight distribution, compliance with the truck rated capacity, and that the load does not exceed the axle service factor of 1.15 for continuous duty material handling applications.
Q: Which Toyota electric lift truck models use this 00591-37866-81 axle assembly?
A: The 00591-37866-81 is an OEM Toyota axle designed for Toyota electric counterbalance lift truck series. Compatibility spans multiple Toyota models equipped with 30 inch load centers and 3/4 inch NPT hydraulic ports. Verify your truck model and serial range against the OEM parts catalog before ordering.
Q: What material is the 00591-37866-81 axle forged from and how durable is it?
A: The 00591-37866-81 is machined from SAE 1045 forged steel with minimum yield strength of 80,000 PSI (Grade 8 equivalent). The shaft features a phosphate anti-corrosion coating to resist rust in industrial warehousing and cold storage environments. High-strength steel construction provides durability in high-cycle material handling service.
Q: What bearing type does this axle use and how long do bearings last?
A: The 00591-37866-81 uses tapered roller bearings designed for the radial and thrust loads inherent in lift truck operation. Bearing service life depends on load cycling frequency, maintenance lubrication schedule, and operating conditions. Well-maintained axle bearings typically provide 5 to 10 years of service in normal material handling duty.
Q: What are the physical mounting specifications for the 00591-37866-81 axle?
A: The 00591-37866-81 features an 8 inch bolt circle mounting pattern, 13.5 inch shaft length, and a 3/4 inch NPT hydraulic port for tilt and load control. The axle operates at 750 RPM nominal input shaft speed at rated drive power with 85 percent efficiency rating under full load conditions.
