  Q: How to service and repair the piston on Chevrolet Tracker?

  A:

  One must acquire a Piston Ring compressor (J8037) as the initial tool before commencing Piston maintenance. Begin your repair work by taking off the Cylinder Head from the cylinder block before proceeding to remove the Oil Pan together with the oil pump strainer. A ridge reamer should remove ridges along with carbon deposits from the cylinder bore top to avoid harming Piston Ring lands. Draw a cylinder label directly on each Piston and connecting rod and connecting Rod Bearing cap. Use hose pieces wrapped over connecting rod studs to shield the Crankshaft and cylinder wall while extracting the Piston and connecting rod from the cylinder bore. After this detach the two nuts and the connecting Rod Bearing cap. The mechanic should take apart the Piston and connecting rod components for inspection before picking the right connecting Rod Bearing along with Piston. Use clean engine oil to coat the components including pistons and rings and cylinder walls as well as connecting rod bearings and crank pins. An additional hose must cover the connecting rod studs when you install them to protect against potential installation damage. Position the arrow mark located on top of the Piston towards the Crankshaft Pulley direction. The Piston Ring compressor (J8037) should be utilized to compress Piston rings followed by Piston and connecting rod installation into the cylinder bore. Strike the Piston head with a hammer handle while holding the Piston Ring compressor (J8037) on top of the cylinder block until all Piston rings locate correctly. Screw the connecting rod bolts to the rod cap while using two nuts that need tightening to 35 nm (26 ft. Lbs.). The last part involves installing the engine Oil Pan along with the Cylinder Head onto the cylinder block.

  Q: How to replace the piston, connecting rod, and bearing in an engine on Chevrolet Tracker?

  A:

  After removing the Cylinder Head from the cylinder block maintain this order: Oil Pan removal and oil pump strainer removal. An appropriate tool known as the ridge reamer removes top cylinder bore carbon to eliminate ridges which prevents ring land damage. Write down the cylinder identifier on all three parts including connecting Rod Bearings and connecting Rod Bearing caps. During Piston and connecting rod removal from the cylinder bore protect the components by placing a hose over the connecting rod studs after removing twc nuts and the connecting Rod Bearing cap. Examine the Piston and connecting rod assembly before picking the correct connecting Rod Bearing while also selecting the suitable Piston. Clean engine oil receives a thin layer application on pistons rings cylinder walls connecting rod bearings and crank pins. Put another piece of hose over the connecting rod studs before putting the rod in place to reduce installation-related damage. Check that the arrow mark on the Piston's top faces toward the Crankshaft pulley position. The j 8037 ring compressor (J 8037) assists in compressing Piston Rings before you place the Piston and connecting rod inside the cylinder bore. Use a hammer handle to tap the Piston as you smoothly push the j 8037 against the cylinder block's top until all rings reach the cylinder bore position. For connecting rod bolt removal, fasten the Rod Bearing cap to the assembly with twc nuts after wiping off the hose pieces. Tighten these nuts to 35 nm (26 ft. Lbs.). After completing these steps install both the engine Oil Pan and the Cylinder Head onto the cylinder block.
