Camshaft - Magnetic Crack Inspection (1-18) Section 1 - Cylinder Block - Group 01 M11 Page 1-54 Caution: Do not exceed the temperature or time limits with the gear in the oven. The gear will be damaged. Put the camshaft gear into an oven heated to 235°C [450°F] for a minimum of one hour but not longer than six hours. Caution: Wear insulated gloves, Part No. 3823730, when handling heated parts. Hot parts can cause serious per- sonal injury. Caution: The timing marks and part number on the gear must be facing away from the camshaft when the gear is installed to prevent engine damage. Use Lubriplate W No. 105, or equivalent to lubricate the camshaft gear mounting surface. Caution:
Keep the camshaft in a vertical position until the gear has cooled. Do not use water to reduce the cooling time, the gear will crack. Remove the gear from the oven, align the keyway in the gear with the key in the camshaft and install the gear on the camshaft within 30 seconds. Measure the camshaft thrust plate clearance. Camshaft Thrust Plate Clearance mm in 0.13 MIN 0.005 0.33 MAX 0.013 Camshaft - Magnetic Crack Inspection (1-18) The camshaft gear and thrust plate must be removed before performing this inspection. Refer to Procedure 1-17, to remove the camshaft gear and thrust plate.
