Bearing shells and full circle inserts are available for a wide variety of OHC engines and usually cost less than buying or making oversized cams. Dennis Espinoza, an engineer with Dura-Bond, Carson City, NV, says his company has bearing shells and inserts for many OHC applications. The company’s catalog can be downloaded from its Web site at www.dura-bondbearing.com/prodinfo/index.htm.
Espinoza said Dura-Bond is constantly developing bearings for new applications as demand dictates. New bearings that are just now being introduced include ones for the 1997-2000 Ford 4.0L SOHC V6 (FA-6), the 1996-2000 Ford Taurus 3.0L DOHC Duratech (FA-7R, FA-7L & FA-7LA), the 3.0L DOHC V6 Duratech engine in the Lincoln LS (FA-8R & FA-8L), the 1992-98 Acura 2.5L SOHC 5-cylinder engine (HA-5), and the 1993-94 Mitsubishi/Chrysler Laser/Eclipse 2.0L DOHC engine (MIA-6).
“Dura-Bond uses babbit faced bearings with steel backings. The microbabbit provides good conformability and we feel is a much better bearing surface than aluminum. They won’t seize like aluminum will,” said Espinoza.
