  Q: How to replace the Crankshaft Gear and timing chain sprockets on Chevrolet SSR?

  A:

  Begin by eliminating the Oil Pump followed by Crankshaft rotation for alignment with Crankshaft and camshaft sprocket timing marks before performing any further work since post-Timing Chain removal Crankshaft movement endangers piston assemblies and valves. Start by removing the camshaft sprocket bolts then move to disconnect the camshaft sprocket and Timing Chain. A three-jaw puller (J 8433) along with a Crankshaft end protector (J 41816-2) and Crankshaft sprocket remover (J 41558) should be used to detach the Crankshaft sprocket. After sprocket removal, remove the Crankshaft sprocket key if present. A thorough cleaning process should precede sprocket inspecting before you install either component. Index the Crankshaft key in its keyway before tapping both ends to proper position. Position the Crankshaft sprocket at the Crankshaft front by matching the Crankshaft key with the sprocket keyway before fully locking it into position using the j 41665 Crankshaft balancer and sprocket installer (J 41665). Rotate the Crankshaft sprocket until the alignment mark is at the 12 o'clock position, ensuring the camshaft sprocket locating pin aligns with the camshaft sprocket alignment hole, and that the sprocket teeth mesh with the Timing Chain. Align the camshaft and Crankshaft sprocket marks by positioning the camshaft sprocket alignment mark at the 6 o'clock position before installing both sprocket and Timing Chain. Before tightening the camshaft sprocket bolts to 35 nm (26 ft. Lbs.), users can rotate the camshaft or Crankshaft sprockets to achieve proper timing mark alignment. Finally, reinstall the Oil Pump.
