P31521 Trunnion Assembly (Used) (Superseded by 10731521) l JLG
P31521 Trunnion (Used)
Item Description: Trunnion Assembly (Pivot Mount)
Part Number: P31521
Superseded By: 10731521
Condition: Used
Brand: JLG / SkyTrak
Category: Structural / Pivot Components
Product Overview
This is a genuine JLG Trunnion Assembly, removed from a high-capacity machine (standard on many SkyTrak and JLG series). The trunnion is a heavy-duty pivot mounting component designed to support and allow for the controlled oscillation or rotation of large mechanical assemblies, such as axles or large hydraulic cylinders.
The original part number P31521 has been superseded by 10731521. This used OEM assembly is a critical structural part that must withstand immense sheer and compressive forces, especially in 10,000 lb capacity machines. It provides a reliable, cost-effective solution for replacing a cracked, worn, or "out-of-round" pivot mount.
