  1. Remove the drive belt (see «DRIVE BELT REMOVAL/INSTALLATION»(/acura/tsx/ii-2008-2014/remont/charging-system/#charging-system-4-cyl__drive-belt-removalinstallation) ).
  2. Remove the oil pan (see «OIL PAN REMOVAL»(/acura/tsx/ii-2008-2014/remont/mechanical/#engine-block-4-cyl) ).
  3. Loosely install the crankshaft pulley.
  4. To hold the rear balancer shaft, insert a 6 mm long pin punch (A) (Snap-on PPC108LA or equivalent) into the maintenance hole in the balancer shaft holder and through the rear balancer shaft.
  5. Turn the crankshaft counterclockwise to compress the oil pump chain auto-tensioner.
  6. Remove the crankshaft pulley.
  7. Align the holes on the lock (A) and the oil pump chain auto-tensioner (B), then insert a 3.0 mm (7/64 in) diameter pin (C) into the holes. Turn the crankshaft clockwise to secure the pin.
  8. Use a transmission jack to lift the transmission 30-40 mm (1.18-1.57 in), then remove the oil pump chain auto-tensioner.
  9. Remove a transmission jack.
  10. Support the engine with a transmission jack and wood block under the edge of the engine block. NOTE: Do not hit the oil strainer when placing the jack on the edge of the engine block.
  11. Remove the cam chain (see «CAM CHAIN REMOVAL»(/acura/tsx/ii-2008-2014/remont/mechanical/#cylinder-head-4-cyl__cam-chain-removal) ).
  12. Loosen the oil pump sprocket mounting bolt.
  13. Remove the oil pump sprocket (A) and the oil pump chain guide (B).
  14. Remove the oil pump chain (C).

  1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with the pointer (B) on the engine block.
  2. Install the oil pump chain on the crankshaft sprocket with the colored link plate (A) aligned with the TDC mark (B) on the crankshaft sprocket.
  3. Set the oil pump chain on the oil pump chain sprocket (A) with the punch mark (B) aligned with the center of the two colored link plates (C), then install the oil pump chain sprocket to the oil pump.
  4. To hold the rear balancer shaft, insert a 6 mm long pin punch (D) (Snap-on PPC108LA or equivalent) into the maintenance hole in the balancer shaft holder and through the rear balancer shaft.
  5. Apply new engine oil to the threads of the oil pump sprocket mounting bolt (E), then install the oil pump sprocket mounting bolt and the oil pump chain guide (F).
  6. Remove the 6 mm long pin punch.
  7. Install the cam chain (see «CAM CHAIN INSTALLATION»(/acura/tsx/ii-2008-2014/remont/mechanical/#cylinder-head-4-cyl__cam-chain-installation) ).
  8. Remove the transmission jack.
  9. Turn the plate (A) counterclockwise, to release the lock, then push the oil pump chain auto-tensioner arm (B), and set the first cam (C) to the first edge of the rack (D). Insert a 3.0 mm (7/64 in) diameter pin (E) into the hole (F). NOTE: If the chain tensioner is not set up as described, the tensioner will become damaged.
  10. Use a transmission jack to lift the transmission 30-40 mm (1.18-1.57 in), then install the oil pump chain auto-tensioner.
  11. Remove the 3.0 mm (7/64 in) diameter pin (A) from the oil pump chain auto-tensioner.
  12. Install the oil pan (see «OIL PAN INSTALLATION»(/acura/tsx/ii-2008-2014/remont/mechanical/#engine-block-4-cyl) ).
  13. Install the drive belt (see «DRIVE BELT REMOVAL/INSTALLATION»(/acura/tsx/ii-2008-2014/remont/charging-system/#charging-system-4-cyl__drive-belt-removalinstallation) ).
