  Q: How to remove and install Camshaft on 2012 and later Hyundai Accent?

  A: Camshafts must be inspected orally before fitting and the camshaft end-float should be measured before dismantling. It is advisable to start with the removal of the battery by firstly disconnecting the battery cables. Place the engine at the top dead center for the number 1 cylinder, then unbolt and pull off the air cleaner assembly, and the high-pressure fuel pump as well. Next, take off the exhaust OCV mounting bolt, pull the OCV out from the vale cover and, finally, take off the valve cover off. Undo the Exhaust OCV adapter plate screws and pull out the adapter from the head of the cylinder. Some of the tasks include; Pulling off the drive belt, alternator, as well as the water pump. Once the TDC marks are lined up on the two sprockets hold the camshaft with a large wrench and then ease the camshaft phaser sprocket bolts out without fully removing them. Take out the bolt on the side of the engine Blanc There is exposed to the service hole in the timing chain cover If necessary use a clean scraper to clean the Loctite sealer off the threads. Insert a small screwdriver and loosen the tensioner ratchet; pull the chain off the sprocket, and take out the bearing cap and the upper bearing. The rest of the other camshaft cap bolts are to be loosened and the camshafts are to be removed but ensure the caps are arranged to ensure that they are placed back as they where. Take out the lifters to be back, and also to make sure they are arranged correctly and examine all the related parts for any signs of wearing. Measure camshaft endplay with dial indicator, look for bearing wear, measure the camshaft bearing journals, and measure the lobe heights. Check for the camshaft runout and check the lifters for scuffing appearance. During assembly, the lifters need to be cleaned with the engine oil, then the exhaust camshaft lower bearing followed by applying the lubricant to the camshaft lobes and journals before putting the camshaft into an appropriate cylinder head. Next, fit in the upper bearing and the bearing caps should be tightened in the proper manner. Position the timing chain to cover the camshaft sprockets, lock the camshaft in order to prevent it from rotating and then tighten the phaser sprocket bolts to their specified torque. Raise the tensioner link and fit in a new service hole bolt now. For adjustment, right, unscrew the Valve cover, and align number one cylinder to TDC, and also using a feeler gauge, check the clearance that exists between the camshaft lobes and lifters. Perform the same for the other valves simply by rotating the engine and graduating on to the next step. If clearances are beyond the set limits, it is advisable to further detaching the camshaft(s), and measuring the thickness of the lifter(s) to find out the right thickness of the new lifter(s). Once the new lifters and camshafts have been installed clearances should be checked, application of installation lubricant, and then once the components are in their proper position the bearing cap bolts should be tightened to the recommend torque.

  Q: How to inspect and measure hydraulic lifters and camshaft on Hyundai Elantra?

  A: Engines with 1.4L, 1.6L, 2011 and later 1.BL, and 2014 and later 2.0L configurations utilize small post type hydraulic lifters and rocker arms instead of shim bucket style lifters. Begin by visually inspecting the camshaft bearing surfaces for any signs of damage such as pitting, score marks, galling, or abnormal wear, as damaged surfaces necessitate cylinder head replacement. Measure the outside diameter of each camshaft bearing journal and record these measurements, then compare them to the specified journal outside diameter, followed by measuring the inside diameter of each corresponding camshaft bearing. Calculate the oil clearance by subtracting the cam journal outside diameter from the cam bearing bore inside diameter, and ensure the results fall within the specified journal-to-bearing clearance limits; if not, replacement of the camshaft or cylinder head may be required. Assess camshaft runout by placing the camshaft back into the cylinder head and using a dial indicator on the center journal, recording readings as the camshaft is turned, and if the runout exceeds specified limits, the camshaft should be replaced. Measure camshaft endplay with a dial indicator aligned with the camshaft snout, zeroing it before pushing the camshaft rearward and then forward to check the reading; excessive wear on bearing caps indicates the need for cylinder head replacement. Compare camshaft lobe heights using a micrometer, ensuring to measure each intake and exhaust lobe separately, and if the difference exceeds 0.005 inch, the camshaft should be replaced. Inspect the contact and sliding surfaces of each lifter for wear and scratches, ensuring lifters are not laid on their side or upside down to avoid trapping air, and verify that each lifter moves freely in its bore to prevent potential internal engine damage. For noisy valve lifters, run the engine to normal operating temperature, remove the valve cover, and rotate the engine until the No.1 piston is at TDC, then use a feeler gauge to measure clearance between the camshaft lobe and lifter; if clearance exceeds 0.008 inch, inspect the lifter and camshaft lobe for wear. If no clearance exists, depress the lifter to bleed it down and check again, repeating the process for remaining cylinders by following the firing order. If any clearance exceeds the maximum allowed, inspect the camshaft, and if it is in good condition, replace the faulty lifters. Ensure all parts, whether new or old, are thoroughly inspected before reassembly.

  Q: How to inspect, remove, and install camshafts on four cylinder Hyundai Sonata?

  A: Camshafts should always be examined very closely prior to being installed and the end play of the camshaft should always be measured before removing. One can start by removing the cable from the negative terminal of the battery and position the engine at TDI for the number 1 cylinder with the timing marks well aligned. On vehicles built after 2011, untwist the high-pressure fuel pump and the casing of the valve cover and then align the timing belt or chain with the camshaft sprockets. Take off the timing belt or chain, also don't allow the camshaft rotate when you are loosening the sprocket bolts. For vehicles made in 2011 and onwards, do not allow the camshaft to rotate as you relive the tension on the phaser sprocket bolts, then proceed to turn the crankshaft pulley. Check the camshaft endplay and then remove the front camshaft bearing cap and all the other caps in the sequence one at a time arranging the removed caps in sets. Take off the lash adjusters or lifters, bearing all the other parts for any signs of wear and measure the end play of the camshaft using a dial indicator. The bearing surfaces must be visually checked for signs of wear and the camshaft bearing journals as well as lifters must be micrometrical. If any measurement is outside those parameters, the endangered species' part may need to be replaced. Regarding installation, the lash adjusters or lifters should be lubricated, the camshaft placed, and the bearing caps, and bolts tightened while following the sequence. If the car is 2006 or newer change the camshaft oil seal and inspect and adjust valve lash if it is necessary. Correctly position the camshaft sprocket teeth to the timing belt making sure of the alignment marks, also install the camshaft position sensor. For 2006 and later models, if valve clearances are beyond limits use a feeler gauge to adjust, remove the camshaft and lifters to replace the correct thickness. After reassembly clearances should be checked once more before final assembly is done.
