Who This Is For:

Most big box machines aren’t built for daily commercial use. The engines are usually fine — the pumps aren’t. This is how you fix that problem without buying a whole new rig.

Important:

• Make sure your engine is rated for 14.5 HP minimum
• Must be 1” shaft, 3400 RPM
• If you’re unsure, message me — I’ll help you get it right.
