Remanufactured Camshafts Offer Many Advantages: Purchasing a remanufactured camshaft is considerably less expensive than buying a brand new camshaft, but will deliver the same results.
عرض المزيد2 . Pre grinding process: The first step is to inspect the camshaft to see if it needs any welding or other repairs. After the repairs are made, it is cleaned in a ceramic media solvent bath. This gentle scrubbing action removes rust, grease, and baked on oil. The next step in the camshaft grinding process is where the camshaft is verified for ...
عرض المزيدCamshaft is then induction hardened. Stress relieving process is preformed. Camshaft is re straightened. Grinding of journals is completed. Gears are heat treated if required. Camshaft straightened again if required. Gears are cut so both journals and gears are relevant to each other. Crack testing is performed on camshaft.
