A.Remove the front housing. Refer to Disassembly and Assembly, “Housing (Front) – Remove”.
1.Rotate the crankshaft until the number one piston is at the top center position. Timing mark (4) for camshaft idler gear (2) should be in line with timing mark (5) for crankshaft drive gear (6) .
2.Remove the bolts that fasten plate (1) to idler shaft (3) . Remove plate (1) .
3.Slide camshaft idler gear (2) from idler shaft (3) .
4.Use Tooling (A) and a suitable press to remove the bearing from camshaft idler gear (2) .
5.Remove the bolt and idler shaft (3) from the cylinder block.
Installation Procedure
1.Position idler shaft (3) on the cylinder block. Install the bolt that holds idler shaft (3) to the cylinder block. Tighten the bolt to a torque of 70 ± 15 N·m (51 ± 11 lb ft).
2.Use Tooling (A) and a suitable press to install the bearing in camshaft idler gear (2) . Install the bearing until the bearing is 0.40 ± 0.25 mm (0.016 ± 0.010 inch) below the front face of camshaft idler gear (2) .
3.Install camshaft idler gear (2) on idler shaft (3) . Align timing mark (4) for camshaft idler gear (2) with timing mark (5) for crankshaft drive gear (6) .
4.Position plate (1) and install the bolts. Tighten the bolts to a torque of 70 ± 15 N·m (51 ± 11 lb ft).
