Begin the Camshaft replacement on lh6 lmg ly2 and ly5 engines by taking away the radiator support and valve lifters together with engine front cover and
Starter motor. The j 42386-a (
Flywheel Holding Tool) should have its teeth matching the engine Flywheel teeth before installation using one m10-1.5 x 120 mm and one m10-1.5 x 45 mm bolt that you must tighten to 50 n.m (37 lb ft). Rotating the crankshaft sprocket will reveal the alignment marks of the Camshaft sprocket next to the crankshaft sprocket alignment marks while avoiding any crankshaft motion following
Timing Chain removal to prevent damage. Disassemble the components by first removing bolt 206 and parts 205 and 208. Finish removing parts 204 and 203 while taking care to safeguard the Camshaft bearings. Place the Camshaft sprocket bolt at the front hole of the Camshaft to act as a handle when removing the Camshaft from the engine block before removing the bolt. After cleanup of the gasket surface on the engine block install the Camshaft through the bolt as a handle while applying clean engine oil to both Camshaft journals and bearings. Screw in the Camshaft retainer (203) and bolts (204), first tighten hex head bolts created in design one to 25 n.m (18 lb ft) and second design torx(R) head bolts to 15 n.m (11 lb ft). Beginning with en 46330 (Timing Belt Tensioner Retaining Pin) installation the synchronization of Camshaft sprocket timing requires it to face 6 o'clock before Timing Chain (208) and bolt (206) assembly. Check that the Camshaft sprocket markings face 6 o'clock position since the crankshaft sprocket should display its mark at 12 o'clock position during inspection. Proceed by removing tool en 46330 and then tighten the Camshaft sprocket bolt to 90 n.m (66 lb ft) followed by 40 degrees using j 45059 (Angle Meter). Then finish the repair by eliminating both the j 42386-a and bolts before replacing the Starter motor as well as the engine front cover together with valve lifters and radiator support.
