Mi-T-M CBA-4004-1MCM Aluminum Series Belt Drive Pressure Washer

The Mi-T-M CBA-4004-1MCM is a 4,000 PSI / 3.7 GPM gasoline belt-drive pressure washer powered by a 420cc Mi-T-M OHV engine with a CAT triplex pump. The corrosion-resistant aluminum frame with patented vibration isolation plate keeps weight at 156 lbs — identical to the Kohler CH440 variant. External bypass and thermal relief valve protect the pump under continuous duty. 49-state engine; not for sale in California.

Mi-T-M OHV Engine in Commercial Field Use

The Mi-T-M-branded 420cc OHV engine is built to the same specification as the CH440-equipped variant. The Mi-T-M engine option is commonly chosen by buyers who prefer parts sourcing through a single manufacturer (Mi-T-M) rather than managing separate Kohler and CAT service channels. PSI, GPM, and physical dimensions are identical to the 1MCK model at 156 lbs and 47" × 27.5" × 28.5".

Frequently Asked Questions

How does the CBA-4004-1MCM differ from the CBA-4004-1MCK?
The CBA-4004-1MCM uses a 420cc Mi-T-M OHV engine versus the 429cc Kohler CH440 in the 1MCK. Both models use the same CAT pump, deliver 4,000 PSI at 3.7 GPM, weigh 156 lbs, and share identical frame dimensions.
What is the advantage of the Mi-T-M OHV engine in the 1MCM?
Buyers who source all parts and service through Mi-T-M distributors benefit from single-source parts management when the engine is Mi-T-M branded, reducing the need to coordinate between separate Kohler and pump service networks.

The 1MCM uses a CAT triplex pump with external bypass, forged brass manifold, thermal relief valve, and clear-sleeve water filter — identical to the 1MCK.
Is the CBA-4004-1MCM available for California customers?
No. The CBA-4004-1MCM uses a 49-state OHV engine and is not for sale in California. Customers in California should consult the Mi-T-M factory for CARB-compliant alternatives.

The CBA-4004-1MCM achieves 14,800 Cleaning Units (4,000 PSI × 3.7 GPM), placing it in the high-duty category for commercial fleet washing, surface prep, and equipment cleaning.
