Mi-T-M CBA-3504-1MAM — Belt-Drive 3500 PSI with Mi-T-M 420cc OHV Engine

The CBA-3504-1MAM pairs the CBA aluminum belt-drive platform with a 420cc Mi-T-M OHV engine — the same proprietary commercial-duty powerplant used in the CA direct-drive series but mated here to a belt-drive transmission for lower pump speed and extended seal life. AR pump, patented vibration isolation plate, and 13-inch flat-free tires are standard.

CBA-3504-1MAM Mi-T-M Engine and Drive System

  • 420cc Mi-T-M OHV engine — Mi-T-M proprietary commercial-duty engine; same displacement class as competing 420cc engines at a lower acquisition price point.
  • Belt-drive transmission — operates pump at 60–70% of engine RPM; reduces pump temperature and extends seal life versus direct-drive equivalents.
  • AR pump with Mi-T-M Pressure Relief Start — 3,500 PSI output; adjustable unloader sets working pressure without nozzle changes.
  • Forged brass manifold and thermal relief valve — corrosion-proof manifold; thermal relief protects pump if trigger is held closed for extended periods.
  • Corrosion-resistant aluminum frame, 165 lbs., 13-inch flat-free tires — aluminum construction reduces loading effort versus comparable steel-frame units.

Commercial Cleaning Applications at 3500 PSI

The 3,500 PSI range is the commercial sweet spot for surface preparation, concrete cleaning, equipment degreasing, and fleet washing where the higher cleaning force of 4,000+ PSI can damage softer surfaces. Restoration contractors specify 3,500 PSI for brick and mortar cleaning where excess pressure causes efflorescence erosion. Property maintenance companies use the 3,500 PSI class for parking garage floor cleaning, loading dock scrubbing, and dumpster pad maintenance. The Mi-T-M OHV engine option offers cost savings for operations with large fleets where proprietary engine parts procurement is centralized through Mi-T-M's parts network. ETL certified; 49-state engine — not for sale in California.

Frequently Asked Questions

What engine is in the CBA-3504-1MAM?
The CBA-3504-1MAM uses a 420cc Mi-T-M OHV engine — Mi-T-M's proprietary commercial-duty overhead-valve engine designed for the pressure washer duty cycle.
What PSI and GPM does the CBA-3504-1MAM deliver?
The CBA-3504-1MAM produces 3,500 PSI at 3.7 GPM, giving it a cleaning units rating of 12,950. This output is suited for heavy commercial surface cleaning, fleet washing, and equipment degreasing.
Why choose 3500 PSI over 4000 PSI for some cleaning applications?
3,500 PSI reduces surface damage risk on brick, mortar, painted metal, and softwood compared to 4,000 PSI units. For restoration contractors cleaning historic brick facades or delicate masonry, 500 PSI can be the difference between cleaning and etching the surface.
Does the belt-drive system make the CBA-3504-1MAM quieter than direct-drive?
Yes. Belt-drive configurations typically run 3–6 dB quieter than direct-drive units at the same pressure rating because the belt absorbs transmission vibration and the pump operates at lower RPM. This matters on jobs in noise-sensitive environments such as occupied residential properties.
What pump does the CBA-3504-1MAM use?
An AR (Annovi Reverberi) triplex plunger pump with a forged brass manifold and Mi-T-M adjustable-pressure unloader. AR pumps are Italian-manufactured and widely used in commercial pressure washing equipment.
Is the CBA-3504-1MAM available in California?
No. The 420cc Mi-T-M OHV engine is a 49-state configuration and does not comply with California CARB emissions standards. Contact Mi-T-M factory sales for a CARB-compliant alternative.
