2010 Jeep Wrangler Crankshaft Parts and Q&A

• Q: How is a Crankshaft Installed in an Engine on 2010 Jeep Wrangler?

  A: Apply a coat of engine oil over the crankshaft and then place each half of the crankshaft main bearing into the engine block. Fix the crankshaft (11) into place in the engine block and install the main bearings. Check the main cap bolts for signs of stretching (They might appear as unusually wide grooves on the bolt head) (2) and replace those that are stretched; check each bolt thread, ensuring it's not wider than normal and that it fits snugly against a straight edge (2). Attach the bearing caps (1,2,3,5) and bolts, tighten them to a torque of 41 Nm (30 ft. lbs.), plus 1/4 turn and add a new cross bolt and washer assembly during the next step. Tighten the new cross bolts and washer assemblies (8) to a torque of 61 Nm (45 ft. lbs.). Attach and install both the connecting rod and the bearing caps on the crankshaft and then add the crankshaft rear oil seal. You should next put in the crankshaft sprocket, install the timing chain and then replace the camshaft sprocket. Attach the timing chain cover and, right after, the oil pick-up tube and oil pan. Following that, you'll need to install the engine assembly.
