• Q: How to service the camshaft on the LH bank on 2006 Toyota Avalon?

  A: The procedure for servicing the LH bank camshaft on a 2GR-FE engine starts by removing the engine assembly combined with transaxle and engine wire while also taking out front frame assembly and starter assembly as well as automatic transaxle assembly and oil level gauge guide sub-assembly and both exhaust manifold sub-assemblies (RH and LH). First choose Special Service Tools: 09213-70011 (09213-70020), 09330-00021 to remove the drive plate & ring gear sub-assembly, fix the engine assembly and then continue removing idler pulley sub-assembly No.2, engine mounting bracket RH, V-ribbed belt tensioner assembly, water pump pulley, timing gear cover No.2. Remove the engine mounting stay No.2 RH, engine mounting bracket front No.1 LH, water inlet housing, crankshaft pulley using Special Service Tools: 09032-00100, 09213-70011 (09213-70020), 09330-00021, 09950-50013 (09951-05010, 09952-05010, 09953-05020, 09954-05021), oil pan sub-assembly No.2, oil strainer sub-assembly, oil pan sub-assembly, intake air surge tank, ignition coil assembly, oil pipe No.1, oil pipe No.2, cylinder head cover sub-assemblies (RH and LH), timing chain cover sub-assembly, and timing chain cover oil seal. Keep the camshaft horizontal so no damage happens during removal of the LH bank No.2 chain that includes chain sub-assembly and camshaft timing gears followed by chain tensioner assembly No.1 from TDC/compression position. The camshaft housing sub-assembly LH requires careful removal since contact surfaces should not get damaged. The timing gear installation sequence begins with this step while the technicians should ensure that each camshaft stays level during installation and also apply engine oil to both the camshaft journal and bearing cap. Install the camshaft housing sub-assembly LH by first applying seal packing (approx. 10 inches long) material (Part No. 08826-00080 or equivalent) to form a continuous bead before installation. The assembly requires new gaskets and proper bolt tightening according to specifications before installing chain tensioner assembly No.3. Place the camshaft timing gears along with the No.2 chain (LH bank) properly aligned before following the torque specifications. Retrain the service steps in reverse sequence by following the checklist for time chain cover oil seal along with the timing chain cover sub-assembly and water inlet housing, engine mounting bracket front No.1 LH, cylinder head cover sub-assemblies, oil pipes, ignition coil assembly, intake air surge tank, oil pan sub-assemblies, crankshaft pulley and engine mounting stay No.2 RH. The installation process ends with rejoining the drive plate & ring gear sub-assembly, exhaust manifold sub-assemblies, oil level gauge guide sub-assembly, automatic transaxle assembly, starter assembly, front frame assembly, engine wire, and the engine assembly with transaxle.
