  Q: How to replace the camshaft on Chevrolet K3500?

  A:

  The replacement process for the Camshaft begins with disconnecting the negative cable of the battery. Begin the procedure by removing the air intake duct from the Throttle Body then proceed to remove the grille from the vehicle and the Radiator assembly and end with removing the air conditioning condenser. The engine block requires removal of upper and lower Intake Manifolds before extracting valve Rocker Arm covers followed by valve rocker arms then valve push rods until the last step involves removing valve lifters from the engine block. The crankshaft balancer along with the Water Pump along with engine front cover and crankshaft position reluctor ring must be removed from the motor. The sprocket remover (J 28509-A) helps remove the Camshaft sprocket after which users should take out the Camshaft retainer bolt and retainer. Three 5/16 18 bolts measuring 4 to 5 inches in length must be installed into Camshaft threaded bolt holes to draw out the Camshaft from the engine block while avoiding Camshaft Bearing damage. Before placing the Camshaft inside the engine block you must first coat its bearings and lobes with engine oil supplement gm p/n 1052367. Hang the Camshaft retainer and tighten its bolts to 12 nm (106 inch lbs.) after you have removed its three 5/16 18 bolts. The seal installer (J 22101) allows installation of the crankshaft sprocket before proceeding with the Timing Chain and Camshaft sprocket. The installation of Camshaft sprocket bolts requires a torque setting of 30 nm at 22 ft. Lbs. Reinstall the crankshaft position reluctor ring along with engine front cover, water pump, crankshaft balancer, valve lifters, push rods and valve rocker arms. The next step includes mounting the lower and upper intake manifolds after which you should install valve Rocker Arm covers, air cleaner duct, radiator and air conditioning condenser and grille. The last step involves placing the Drive Belt on drive pulleys while reinstalling the battery negative cables.
