Crankshaft — installation (Hyundai Elantra J1)

Regardless of how the bearing size was determined, to determine the clearance size, use plastic to measure the clearance.

Clean the backs of the new main bearing inserts and place the halves with the oil hole on the main bearing seats in the cylinder block.



Install the other halves from each set into the corresponding bearing caps. Make sure the key on each bearing fits into the slot in the cylinder block or cover.

Caution: Do not hammer the bearings or scratch the bearing faces. No lubrication is required yet.

Wipe the bearing seating surfaces in the block and the crankshaft main journals with a clean cloth. Check or clean the oil holes in the crankshaft.

Carefully place the crankshaft on the main bearings. Before finally installing the crankshaft, it is necessary to check the oil clearance of the main bearings, which is determined by simply measuring the seat diameters or using a special measuring plastic.



Cut off several pieces of plastic of suitable size to measure the gap (they should be slightly shorter than the width of the main bearings) and place one piece on each main journal of the shaft parallel to its axis.

Clean the bearing surfaces in the caps and install the caps in their places. Do not move the plastic. Apply a little oil to the bolt threads.

Tighten the main bearing cap bolts in three stages to the specified torque value. Do not turn the crankshaft during this operation.

Loosen the bolts and carefully remove the bearing caps.

Compare the width of the crushed plastic on each neck to the scale printed on the bag of plastic and determine the gap. Compare the obtained results with the technical data.

Attention: The plastic bag has scales in mm and inches, do not confuse them.

If the gap is not within the norm, the bearing shells may be the wrong size. Before deciding whether to replace the bearings, check to see if any dirt or oil has gotten between the bearing and the cover. If one end of the gap measuring plastic is significantly wider than the other, the neck may be tapered.



Carefully clean all traces of clearance plastic from journals and bearings. Avoid scratching the bearing surfaces.

Final installation of the crankshaft

Carefully remove the crankshaft from the engine. Clean the bearing surface in the block, then apply a uniform layer of engine oil to them.



Lubricate the crankshaft surfaces in contact with the seals with clean engine oil.

Make sure the crankshaft journals are clean, then place the shaft back in the cylinder block.

Clean the bearing surfaces in the caps and apply grease to them.

Place the covers back in place.

Caution: Before installing the covers, check the inserts in the cover beds again. The liner of the 3rd bearing should be without an oil groove, but the others should have one.

2.0 liter engine: install thrust washers on the center main bearing.



Apply a thin coat of oil to the threads and underside of the bolt heads, then install them.



Tighten the nuts of all main bearing caps except the number 3 thrust bearing cap to the specified torque value. Move the shaft back and forth to seat the thrust bearing shells, then tighten the number 3 cover nuts to the specified torque.

Measure the shaft play using feeler gauges or an indicator (see above).



Turn the crankshaft by hand several times and check if it is seizing.

Using a mandrel, press the oil seal into the rear cylinder block cover.

Attention: The seal (2) must be located in the housing (1) according to the figure. Hole A should be at the bottom.

Using a drift, place the rear cylinder block cover (oil seal) onto the crankshaft journal and secure the cover to the block.
