Information:
--------------- END SUPPLEMENT ---------------SUPPLEMENT: JUNE 22, 1998Service Magazine SEPD0354, Article 33, Page 32, April 14, 1997; "Abrasion Resistant Grids For Improved Multi-Tow Module (IMRM) And Advanced Modular Cooling System (AMOCS) Radiators".In the chart titled "Sandblast Grid And Ejector Fan Adaptability Chart", the sandblast grid part number for D7H Track-Type Tractors equipped with IMRM Radiators is listed as 1Z-0766. This part number is for the ejector fan arrangement. If only the sandblast grid is needed, the correct part number is 9Y -7151.
--------------- END SUPPLEMENT ---------------Description of Change: In applications where there is blowing sand or abrasive material kicked up by the machine, sandblasting can be a problem. Sandblasting is the erosion of radiator tubes and fins by fine particles. This normally only occurs with machines equipped with blower fans. After a period of time, sandblasting can cause radiator coolant leaks. The abrasion resistant grid deflects and slows the particles so they pass through the radiator without wearing the tubes or fins. This will give the radiator a longer service life. An ejector-type blower fan will also lessen sandblasting problems. The ejector fan has the back edge of its blades bent around into a hook shape. This makes a channel along the back of each blade which takes most of the debris out of the air flow and discharges it radially.
Ejector-type blower fans are available as factory custom attachments.
In applications where sandblasting is not a problem, use of the abrasion resistant grid is not recommended. However, larger loose particles may get lodged between the grid and radiator and make frequent cleaning of the radiator necessary.
The IMRM and AMOCS radiator cores with (nine fins per inch) do not have as much tube protection as the folded core design, and require sandblast grids for even moderate usage in sandy conditions.
Sand comes off the fan blades at fan operating speed (about ten times air speed velocity) at a 45 Degree angle. The sandblast grid makes the sand take a bounce before entering the radiator core.
