• Structural Support for the Dynamo — Keeps the dynamo securely positioned on the engine, preventing movement that could cause misalignment, premature wear on the charging circuit, or output inconsistencies.
• Verified Part Number — Order by part number EM125 with confidence; this is the exact Multiquip OEM reference for this stay across all compatible models listed.

The dynamo stay is a bracket or support arm that holds the dynamo — also known as the alternator or charging generator — firmly in place on the engine. By securing the dynamo at the correct angle and distance, the stay maintains proper belt tension and alignment between the dynamo pulley and the engine drive pulley. When a dynamo stay becomes cracked, bent, or broken, the dynamo can shift under load, causing belt slippage, uneven wear, loss of charging output, or complete dynamo failure. Replacing a damaged stay promptly restores correct dynamo positioning and protects the surrounding components from further damage.
