LAB #7 Reassembly

Get Check Off Sheet Before you start, make sure you get a reassembly packet from Mrs. Winegar. If you do not have her check your work and sign the form, you will have to start over.

Piston Rotate the piston rings so that the ring gaps are 120 degrees apart and not aligned. Have instructor check.

Install the Piston Oil the wall of the cylinder, if not the piston could seize, you would be replacing the engine housing, rings, piston, connecting rod. $$$$$ Get a ring compressor and compress the rings on the piston, then insert the piston into the engine block.

Piston Rotate the piston so it is in the correct position.

Install Crankshaft Put a lot of oil on the journal, if you do not, the engine could seize and you will be replacing the crankshaft and the connecting rod. $100. Install the crankshaft into the block.

Piston Rod Cap Rotate the crankshaft so access to the rod cap can be gained to install the rod cap. Finger tighten both bolts. Using a 10mm socket snug the bolts. Using a torque wrench torque the bolts to 100 inch pounds. No more or no less. Engine failure if you do.

Tappets Insert the tappets back into the engine block.

Camshaft Replacement Insert the camshaft back into the block. Make sure the timing marks on the camshaft align with the timing marks on the crankshaft.

Crankcase Cover Make sure the metal gasket from the crankcase is reinstalled on the crankshaft before putting the cover on. Make sure gasket on the crankcase cover is good, gently replace the cover onto the engine block.

Crankcase Cover Finger tighten the six crankcase cover bolts Using the star pattern method snug the six bolts with a socket. Again, using the star pattern, torque each bolt to 110 inch pounds.

Rotate Piston Before you move on. Rotate the piston, to make sure everything moves as it should.

Install Flywheel Brake Finger Tighten the two bolts holding the brake to the block. Using a 10mm socket install the two bolts that connect the flywheel brake. Note the two spacers that hold the flywheel brake up off the engine block. Torque to 100 inch pounds.
