Honda 8-97176-813-0 Piston, Grade=B

Before fitting the piston and connecting rod, provide that the cylinder bore is free from deposits, and the top land of each cylinder is lightly statutory, crank-shaft is properly inserted. Take off the cap of the number one connecting rod, be sure to remember the scratches made and then clean the bearing surface of the connecting rod with a clean cloth. The new upper bearing insert should be cleaned and should be inserted in the connecting rod so that the tab of the insert goes into the recess and the oil holes meet without using the lubricant. Do the same for the lower bearing insert working in the rod cap. Align in a circle the gaps of the piston ring around the piston; each rod cap bolt have rubber hose sections that can be slid over, to compress the rings of the piston while leaving a part of the piston skirt to allow easy insertion into the cylinder. Coat the piston and rings with clean engine oil, then fit a piston ring compressor and making sure that gauge mark is facing front of the engine more easily compressed the piston into the engine bore. When doing this ensure that they fit well on the block then slowly push the piston into the cylinder while placing the conntacting part of the connecting rod on the crankshaft journal without a heavy force that may harm the piston or the rings. After installation, use Plastigage to check the connecting rod bearing oil clearance, see that the bearing faces are clean and grease before replacing the rod cap and tightening the nuts in three stages. Do it for the other assemblies with the bearing inserts and connecting rods clean, with attention to the right piston/rod combinations and with greasing the cylinder walls and the bearing faces. After all assemblies are in place perform a binding check on the crankshaft via rotation and measure the connecting rod end-play to specifications. In 3.2 L V6 engines, following the tightening of the main and connecting rod caps, fit the oil gallery assembly and fasten the bolts in the sequence. The balancer unit is located between the oil strainer and the crankshaft: it includes two counter rotating shafts linked to the crankshaft; backlash should be adjusted and is best checked by a dealer service department. Backlash can be altered by changing the spacer shim between the balancer unit and the engine block and after adjustment the balance unit has to be installed in the correct manner using the correct shim and then aligning it in the right manner before proceeding to tighten the retaining bolts.
