cat 3600 power head exchange program

As part of our offerings, Cooper will provide complete CAT 3600 power heads with pre-installed PreChambers. The fully assembled heads and PreChamber are hydrostatically pressure tested, certified, and are delivered ready to install with our premium head gasket kit.

THE PROCESS

  • CAT 3600 heads are fully disassembled, cleaned, and inspected.
  • All freeze plugs are removed and replaced with new plugs. The head is hydrostatically pressure tested to verify the integrity of the head.
  • Heads are fully assembled using all new premium components including springs, valve keepers, Markisches Werks valves, and valve seats.
  • Used, re-qualified, and or reconditioned parts are not utilized.
  • A Rottler CNC machine tool is utilized to machine all valve seats to ensure precise concentric and vertical alignment of the valve seat, the valve guide, and the valve land.
  • Full assembly of the head includes new PCC components. 
  • The assembled head is then pressure tested to assure readiness for operation.
  • Delivered head assembles are ready for immediate installation on the engine. All gaskets are incorporated into the assembly or provided as part of the delivered head kit.
  • Head UX program is available for selected customers.

cooper cat 3600 pre-chambers

Our standard one-piece and exclusive two-piece Pre-Chambers are designed in collaboration with the Department of Energy’s (DOE) Sandia National Laboratory and the Combustion Research Facility. Our Pre-Chamber system, which is made with billet, has been fully tested and vetted in the field by both producers and midstream pipeline companies in the harshest environments.

ADVANCED DESIGN  |  Our patent-pending designs feature a Hastalloy 242 seal with wound titanium spring between the body and the removable tip that is certified to 26,000 psi (17,093 bar) and provides continuous positive pressure against the sealing surfaces under all conditions — guaranteeing that leaks will not form.

QUALITY CRAFTSMANSHIP  |  Our Pre-Chambers are manufactured in the USA under AS9100 (aerospace) certification. We are so confident in our product that we offer the industry’s best warranty: 90 days “no questions asked” along with our 25,000-hour extended performance warranty.

CONVENIENCE FOR THE CUSTOMER  |  Our Pre-Chambers and fuel check valve kits come pre-packaged with all of the necessary seals and gaskets required for installation. If you are performing a top end, we also offer a premium head gasket kit.

WANT MORE QUALITY & CONVENIENCE  |  We now  offer complete heads with pre-installed Pre-Chambers. The fully assembled heads and Pre-Chamber are hydrostatically pressure tested, certified, delivered with our premium head gasket kit, and come ready to install. They also come with an exclusive inconel combustion gasket containing a guaranteed 25,000 hour life.
