  Q: How to remove the camshaft on Toyota FJ Cruiser?

  A:

  Disassembly of the 1GR-FE engine camshaft requires technicians to begin with disconnecting the negative battery cable terminal and draining engine coolant. The V-bank cover stands alongside the air cleaner assembly and throttle body bracket and oil baffle plate and No. 1 and No. 2 surge tank stays and intake air surge tank and Ignition Coil assembly must be taken away first. You need to remove the cylinder head cover sub-assembly LH alongside its sub-assembly by extracting 10 bolts and 3 seal washers as well as two nuts and one gasket. For the TDC/compression of the first cylinder position the crankshaft pulley groove at "0" timing and ensure alignment marks on both camshaft timing gears with their bearing caps. Appy paint marks to the No. 1 chain links at the positions that match the timing marks. Remove the No. 1 chain tensioner assembly by removing its four bolts while also removing the timing chain cover plate with the gasket and then fix the stopper plate of the tensioner. The procedure calls for camera leveling and damage prevention before using an installation pin to support the No. 2 tensioner chain and slow bolt loosening according to the specified order. Start with the chain tensioner assembly removal of No. 2 followed by cleaning the No. 1 camshaft using the following steps: loosen the timing gear set bolt then slide the gear and solve bearing caps according to the specified sequence of bolt removal. To avoid damage keep the camshafts level during this process before removing the No. 4 camshaft sub-assembly and No. 3 chain tensioner assembly. These procedures will also be followed for the No. 3 camshaft sub-assembly while using string to tie the No. 1 chain to prevent objects from entering the timing chain cover.

  Q: How to install the No. 3 camshaft sub-assembly on Toyota FJ Cruiser?

  A:

  Installation of the No. 3 camshaft sub-assembly requires a level position for the camshaft to avoid journal surface damage on the cylinder head. The yellow link should align to the camshaft timing gear timing mark dots before putting new engine oil on the camshaft thrust region and journal portions and using the No. 1 chain to rest on top of the No. 2 chain. Set the camshaft timing gear knock pin through its hole while the hole faces the No. 3 camshaft knock pin followed by fitting the camshaft timing gear set bolt for temporary use. Drop the No. 2 cylinder cam lobes on the bank 2 cylinder head before positioning the 4 bearing caps at their locations and applying engine oil to the bolt threads and under their heads. The installation of 8 bearing cap bolts must be carried out with multiple steps while following this sequence: start with 10 mm head bolts and tighten to 9.0 Nm (92 kgf-cm, 80 in-lbf) then continue with 12 mm head bolts and torque them to 24 Nm (245 kgf-cm, 18 ft-lbf). Secure the hexagonal part of the No. 3 camshaft with a wrench before tightening the camshaft timing gear set bolt to 100 Nm (1,020 kgf-cm, 74 ft-lbf). Clear the hole of the No. 3 chain tensioner and insert a 1.0 mm (0.039 in.) pin through it while pressing in the tensioner. Then place the camshaft timing gear and No. 3 chain tensioner with yellow mark links touching both camshaft timing gear marks before tightening the tensioner bolt to 19 Nm (194 kgf-cm, 14 ft-lbf). For the No. 4 camshaft sub-assembly installation maintain the camshaft at a level position and align its knock pin with the camshaft timing gear knock pin before fitting into place followed by temporary installation of the camshaft timing gear set bolt. Place the 4 bearing caps into correct positions while applying light engine oil to the bearing cap bolt threads before uniformly installing and tightening the 8 bolts in their specified joining sequence. Instruct the technician to apply 100 Nm torque to the No. 4 camshaft camshaft timing gear set bolt and extract the No. 3 chain tensioner pin. Moving the crankshaft pulley clockwise in a slight rotation releases the chain tension between the camshaft timing gear (bank 1) and crankshaft timing gear. To install the No. 1 camshaft first position the yellow mark connection against the 1 dot timing mark on the camshaft timing gear while adding new motor oil to all camshaft thrust portions and journals. Then fit the No. 1 chain to the No. 2 position on the timing gear before guiding the No. 1 camshaft knock pin hole into placement with the timing gear opening. First install the set bolt provided with the camshaft timing gear then place the No. 1 camshaft on the bank 1 cylinder head with its No. 1 cylinder cam lobes facing downward before you install the bearing caps to their proper locations while applying engine oil to bearing cap bolts and their threads and finally tightening all equal bearing cap bolts in sequence. The worker should use a wrench to rotate the No. 1 camshaft clockwise until the timing mark of the camshaft timing gear lines up with the timing mark of the camshaft bearing cap. Then they should align the paint mark of the No. 1 chain with the timing mark of the camshaft timing gear while holding the hexagonal portion of the No. 1 camshaft with a wrench to tighten the camshaft timing gear set bolt to 100 Nm. Attach the No. 2 chain tensioner assembly by pushing in the tensioner while placing a pin of dia 1.0 mm (0.039 in.) into the hole before fixing it. Install the camshaft timing gear along with the No. 2 chain tensioner. Then align the yellow mark links with the timing marks of the camshaft timing gears before tightening the No. 2 chain tensioner bolt to 19 Nm (194 kgf-cm, 14 ft-lbf). The process of installing the No. 2 camshaft requires leveling it before placing it on bank 1 cylinder head with No. 1 cylinder facing upward followed by bearing caps installation at their appropriate positions. Adding engine oil to bearing cap bolts threads and heads and proceeding to a sequential torque application of all bearing cap bolts. Apply a wrench to turn the No. 2 camshaft clockwise until the knock pin matches the knock pin hole of the camshaft timing gear. Use a wrench to hold the hexagonal section of the No. 2 camshaft before tightening the camshaft timing gear set bolt to 100 Nm (1,020 kgf-cm, 74 ft-lbf). Release the tensioner pin from the No. 2 chain tensioner. The installation process for the No. 1 chain tensioner assembly requires users to turn the stopper plate of the No. 1 chain tensioner clockwise followed by pushing in the plunger before turning the stopper plate counterclockwise while inserting a bar of dia 3.5 mm (0.138 in.) into the holes between stopper plate and No. 1 chain tensioner for stopper plate fixation. The No. 1 chain tensioner must be installed with 2 bolts tightened to 10 Nm (102 kgf-cm, 7.4 ft-lbf) before removing the bar for installation of a new gasket with a timing chain cover plate using 4 bolts to 9.0 Nm (92 kgf-cm, 80 in-lbf). Slowly rotate the crankshaft pulley until its groove matches the "0" timing mark of the cover plate while verifying that the camshaft timing gear marks align with bearing cap marks. Finish the job by connecting the cable to the negative battery terminal while applying a torque of 3.9 Nm which is equal to 40 kgf-cm and 35 in-lbf.
