No special alignment tools are required for the CRV engine.
Here is a diagram of the timing marks that should line up when the belt is correctly installed.
1 . Ensure No. 1 cylinder is at TDC of compression stroke. Timing belt drive pulley TDC mark must align with pointer on oil pump housing. See Fig. 3 .
2 . Set intake and exhaust camshaft pulleys to TDC. The TDC marks should align with cylinder head surface with "UP" marks pointing up. See Fig. 3 .
3 . Install timing belt in this sequence: timing belt drive pulley, tension adjusting pulley, water pump pulley, exhaust camshaft pulley, and intake camshaft pulley. See Fig. 4 . DO NOT bend or twist belt excessively. Ensure arrow on used belt points in original rotation direction. Check that crankshaft and camshaft pulleys remained aligned with TDC marks.
4 . Loosen and retighten adjusting bolt to tension timing belt. Install lower and middle covers. Install crankshaft pulley. Tighten pulley bolt to specification. See TORQUE SPECIFICATIONS . Rotate crankshaft pulley 5 -6 turns counterclockwise so timing belt positions on pulley.
CAUTION: Always adjust timing belt tension with engine cold.
5 . To adjust timing belt tension, set No. 1 piston at TDC (White TDC mark on crankshaft pulley aligned with pointer on cover). See Fig. 1 . Loosen adjusting bolt 180 degrees. Rotate crankshaft counterclockwise 3 teeth on camshaft pulley. Tighten adjusting bolt. If necessary, retorque crankshaft pulley bolt.
6 . Ensure crankshaft and camshaft pulleys are still aligned at TDC. If not, timing belt will need to be removed and repositioned.
7 . To complete installation, reverse removal procedure. When installing cylinder head cover gasket, apply liquid gasket (Part No. 08718 - 0001 or -0003) to 8 corners where gasket meets camshafts. Tighten fasteners to specification. See TORQUE SPECIFICATIONS . Adjust drive belts to proper tension.
If your rear differential fluid had not been replaced for quite some time, do so and see if the problem is resolved.
