Mi-T-M CBA-4004-1MAK — Belt-Drive 4000 PSI with Kohler CH440 and AR Pump

The CBA-4004-1MAK delivers 4,000 PSI at 3.4 GPM through an AR pump belt-driven by a 429cc Kohler CH440 OHV engine. Functionally equivalent to the Honda-powered CBA-4004-1MAH, the 1MAK substitutes Kohler's Command Pro series engine for buyers who prefer Kohler's commercial service infrastructure or who standardize their fleet on Kohler powerplants.

CBA-4004-1MAK Kohler CH440 and AR Pump Specifications

  • 429cc Kohler CH440 OHV Command Pro engine — full-pressure lubrication, cast-iron bore, commercial duty cycle; Pressure Relief Start standard.
  • AR triplex pump at 4,000 PSI / 3.4 GPM — forged brass manifold; Mi-T-M adjustable-pressure unloader; 13,600 cleaning units output.
  • Belt drive with two-piece belt guard — pump runs 30–40% slower than engine; guard protects belt from water, debris, and chemical splash.
  • Thermal relief valve and clear-sleeve water filter — automatic pump protection and quick-inspect filter maintenance.
  • Corrosion-resistant aluminum frame, 165 lbs., 13-inch flat-free tires — lighter than steel-frame competitors; flat-free tires prevent site downtime.

Industrial and Commercial Cleaning at 4000 PSI

The CBA-4004-1MAK handles the same heavy-cleaning roster as other CBA-4004 variants: graffiti removal, paint preparation, rubber-deposit stripping, concrete residue cleaning, and heavy equipment degreasing. The Kohler CH440 engine choice specifically benefits agricultural users, rural contractors, and Midwest-based maintenance fleets where Kohler's extensive rural dealer network reduces engine service lead times versus Honda. The CH440's full-pressure lubrication system also performs more consistently in cold-weather starting conditions common in northern climates. ETL certified; 49-state — not for California.

Frequently Asked Questions

What is the difference between the CBA-4004-1MAH and CBA-4004-1MAK?
Both produce 4,000 PSI at 3.4 GPM with an AR pump and belt drive on the same aluminum frame. The 1MAH uses a 389cc Honda GX390 engine; the 1MAK uses a 429cc Kohler CH440. The pressure, flow, frame, and accessories are identical.
What PSI and GPM does the CBA-4004-1MAK produce?
4,000 PSI at 3.4 GPM — 13,600 cleaning units — through a Kohler CH440-powered AR triplex pump.
What does the Kohler CH440 full-pressure lubrication mean for field reliability?
Full-pressure lubrication uses an oil pump to circulate oil under pressure to all bearing surfaces, regardless of engine angle or load. This provides more consistent lubrication than splash systems during sustained high-RPM operation, reducing bearing wear on long cleaning shifts.
Why might a fleet operator choose Kohler over Honda engines?
Kohler has a denser dealer network in rural and agricultural areas than Honda commercial engines. Fleet operators in those regions can service Kohler engines faster and source parts more readily. Large fleets also sometimes standardize on one engine brand to simplify parts inventory management.
Does the CBA-4004-1MAK have a bypass system?
Thermal relief valve is standard. Optional CX-0082 external bypass system is available but must be ordered at the same time as the unit — it cannot be added after delivery.
Is the CBA-4004-1MAK ETL certified?
Yes, ETL certified for the US market. Not for sale in California due to 49-state Kohler CH440 engine configuration.
