Quick answer

Altec has learned that a pressure regulator bolt spacer on certain ST550/720/750 spray trucks and SK430/560 spray units built from July 2020 to February 2023 might not have been installed on the pressure regulator bolt weldment, resulting in the hoses on the tank exceeding their rated pressure on the affected units.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.
