Question 1

How to Remove and Replace the Piston's Connecting Rod in an Engine on Jeep Compass?

Accepted Answer

It is necessary to service pistons, rings and connecting rods strung together, before choosing to remove the connecting rod. Since engine balance matters, only one, three or four pistons should be swapped out, because changing two at a time creates an imbalance. First, lift out the engine and next remove the cylinder head. First, remove the engine oil, then remove the oil pan and the oil filter. Following that, replace the balance shaft with the vanishing point and the ladder frame with a broken ladder. In advance of piston removal, ensure that carbon and debris are cleaned from the cylinder to keep the piston's skirts from being scratched. Use a quality ridge reamer to clean off the ridge on your cylinder's bores so that the pistons are safely out of reach. Put the crankshaft in a central position, center the connecting rods in the rules and write the number on each cap with a marker, as stamping or punching may cause damage. Be sure not to use the connecting rod bolts more than once, since it would be dangerous for the engine. Remove the piston and rod assembly from its cylinder bore one at a time and firmly install the upper bearing cap on the rod as you go.

Question 2

How to Install Piston and Connecting Rod Assemblies on Jeep Compass?

Accepted Answer

Make sure to set the top compression ring and the second compression ring gaps apart, not aligned with the oil ring rail, before installing the piston and connecting rod assembly. Before putting the ring compressor on, ensure that the oil ring expander ends are touching and that the rail gaps match those in the piston head as seen from above. Immerse the piston head and rings in clean oil and with the rings undisturbed, fit the ring compressor onto the piston. The piston has to be pointed where the engine's fan is located. Adjust the crankshaft to place the center of the connecting rod journal inside the cylinder bore and apply clean engine oil to the area. Pick the correct rod bearing size from the crankshaft nose, then put the top half of the connecting rod bearing into the connecting rod. Use a hammer handle to push the piston into the cylinder bore and place the connecting rod into the journal as you go. Because the threads of used bolts may be damaged, replace them with new ones and lubricate them with clean engine oil before putting in the lower half of the bearing. Screw all the bolts just enough to close them and follow with 20 Nm (15 ft. lbs.) on all the bolts except the connecting rod bolts which should be tightened further by 90° to the last turn. Check the side clearance on the connecting rod as directed by the feeler gauge. Installing the ladder frame, balance shaft module, oil pan, cylinder head and lastly the engine should be your next steps.
