Honda GX390 Engine Performance and Fleet Use

The Honda GX390 is one of the most widely serviced commercial gasoline engines in North America, with OEM parts and authorized service centers available nationwide. At 4.0 GPM, the 1MGH delivers faster rinse cycles per hour than the 3.7 GPM variants, making it the preferred choice when throughput matters more than purchase cost. The General pump is a common alternative to CAT with similar durability characteristics in this pressure range.

Frequently Asked Questions

How does the CBA-4004-1MGH differ from the CBA-4004-1MCK?
The 1MGH uses a Honda GX390 engine and General pump, delivering 4.0 GPM versus 3.7 GPM on the 1MCK (Kohler/CAT). It weighs 165 lbs versus 156 lbs. PSI is identical at 4,000.
Why does the CBA-4004-1MGH produce more GPM than the Kohler variants?
The General pump configuration matched to the Honda GX390 is spec'd to deliver 4.0 GPM, versus 3.7 GPM for the CAT pump on the Kohler and Mi-T-M OHV variants. The higher flow rate increases cleaning units from 14,800 to 16,000 CU.
What is the Honda GX390 displacement?
The Honda GX390 is a 389cc OHV 4-stroke engine. It is one of the most widely serviced small commercial engines in North America, with authorized Honda service centers available nationwide.
Is the CBA-4004-1MGH sold in California?
No. The 1MGH uses a 49-state Honda GX390 engine and is not for sale in California. A CARB-compliant alternative must be requested directly from Mi-T-M.
What is the General pump's external bypass system for?
When the trigger gun is released, water circulates through the external bypass rather than building pressure in a closed system. This prevents heat from accumulating in the pump head, which can damage pump seals and valves during idle periods.
