Camshafts Removal/Installation - 2.3L: Installation
WARNING: This page is about a different car, the 2005 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- Install the camshafts with the alignment notches in the camshafts lined up so the camshaft alignment plate can be installed without rotating the camshafts. Make sure the lobes on the No. 1 cylinder are in the same position as noted in the removal procedure. Rotating the camshafts when the timing chain is removed, or installing the camshafts 180 degrees out of position, can cause severe damage to the valves and pistons.
NOTE:
- Lubricate the camshaft journals and bearing caps with clean engine oil.
- Install the camshafts and bearing caps. Tighten the bolts in the sequence shown in three stages.
- Stage 1: Tighten the camshaft bearing bolt caps one turn at a time until tight.
- Stage 2: Tighten the bolts to 7 N.m {0.71 kgf.m 5 ft.lbf}.
- Stage 3: Tighten the bolts to 16 N.m {1.6 kgf.m 12 ft.lbf}.
- Install the camshaft drive gears and hand-tighten the bolts.
- Install the timing chain and sprockets. See TIMING CHAIN REMOVAL/INSTALLATION - 2.3L .
