THE ADVANTAGE

 

Custom engine valve sizing to your exact specifications
Chrome plated engine valve stems resulting in less guide wear
Better engine valve stem-to-guide concentricity and clearance than most OEMs
Standardized engine valve stem sizes SIGNIFICANTLY reduce head remanufacturing time
 

During each step of our remanufacturing process, your engine valves are being continually inspected, measured, gauged and otherwise qualified using the best possible gauging and measuring equipment, including digital and laser micrometers, optical comparators, digital profilometers and hardness testers as well as eddy current and ultrasonic flaw detectors.

The next time you order new engine valves from an OEM, ask them for the specifics on their manufacturing processes and the tolerances that they maintain. Then ask them to provide you with something outside the norm for the same price. That's another CalValves Advantage.


Online Engine Valve Catalog:

Browse our catalog online or download a copy. We add new part numbers regularly. We have approximately 260 different part numbers in our catalog, and another 250 part numbers that are not listed because they are made for specific customers to their proprietary specifications. Most of the non-listed engine valves are for John Deere, Caterpillar, Cummins, EMD and New Holland engines. If you don't see a part number that you're looking for, just give us a call.


Effect of Coolant Use on Engine Valve Guide Diameter During Reaming

View the study.

The majority of the engine remanufacturing industry agrees that benefits are to be had from wet reaming, but little information exists showing, systematically, the specific benefits of using coolant to aid in valve guide reaming. To achieve highly accurate and consistent diameters with a reamer, one must consider process variables that can influence the overall quality of the reamed guide. Variables such as, reamer material or design, valve guide material, temperature at the reamed surface, drill speed, operator movement, etc. must be addressed. View the wet reaming study.


Recovered Materials Advisory Notice IV:

Section B-4 of the RMAN IV specifies, ”that procuring agencies whose vehicles (passenger vehicles as well as medium- and heavy-duty equipment, including trucks, cranes, off-road vehicles, and military vehicles) are serviced by a motor pool or vehicle maintenance facility establish a service contract to require the use of rebuilt vehicular parts in the agencies’ vehicles or establish a program for vehicular parts rebuilding and reuse consisting of either recovering a used vehicular part and rebuilding it, replacing it with a rebuilt part, or contracting to have the part replaced with a rebuilt part. This designation applies to vehicles served by both on-site and commercial facilities.”
