Hi my name is ***** ***** I'll help with your oil pump question.

What engine is in your Ram truck?

The oil pump is driven off of the front of the crankshaft. You will have to remove the timing cover and the timing chains to get it off.

Expert:  Tom replied 1 year ago.

That's going to include removing the crankshaft damper as well. The timing setup on this engine can be difficult without the correct special tools.

  1. Disconnect negative cable from battery.
  2. Drain cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
  3. Remove right and left cylinder head covers (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - REMOVAL).
  4. Remove radiator fan shroud.
  5. Rotate engine until timing mark on crankshaft damper aligns with TDC mark on timing chain cover (Engine Top Dead Center (TDC) Indicator Mark) (#1 cylinder exhaust stroke) and the camshaft sprocket “V8” marks are at the 12 o'clock position (Camshaft Sprocket V8 Marks).
  6. Remove power steering pump (Refer to 19 - STEERING/PUMP - REMOVAL).
  7. Remove access plugs (2) from left and right cylinder heads for access to chain guide fasteners (Cylinder Head Access Plug Location).
  8. Remove the oil fill housing to gain access to the right side tensioner arm fastener.
  9. Remove crankshaft damper (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - REMOVAL) and timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) - REMOVAL).
  10. Collapse and pin primary chain tensioner (Collapsing And Pinning Primary Chain Tensioner).

    CAUTION: Plate behind left secondary chain tensioner could fall into oil pan. Therefore, cover pan opening.

  11. Remove secondary chain tensioners.
  12. Remove camshaft position sensor from right cylinder head (Camshaft Position Sensor—Removal).

    CAUTION: Care should be taken not to damage camshaft target wheel. Do not hold target wheel while loosening or tightening camshaft sprocket. Do not place the target wheel near a magnetic source of any kind. A damaged or magnetized target wheel could cause a vehicle no start condition.

    CAUTION: Do not forcefully rotate the camshafts or crankshaft independently of each other. Damaging intake valve to piston contact will occur. Ensure negative battery cable is disconnected to guard against accidental starter engagement.

  13. Remove left and right camshaft sprocket bolts.
  14. While holding the left camshaft steel tube with adjustable pliers, (Camshaft Rotation—Left Side) remove the left camshaft sprocket. Slowly rotate the camshaft approximately 15 degrees clockwise to a neutral position.
  15. While holding the right camshaft steel tube with adjustable pliers, (Camshaft Rotation—Right Side) remove the right camshaft sprocket. Slowly rotate the camshaft approximately 45 degrees counterclockwise to a neutral position.
  16. Remove idler sprocket assembly bolt.
  17. Slide the idler sprocket assembly and crank sprocket forward simultaneously to remove the primary and secondary chains.
  18. Remove both pivoting tensioner arms and chain guides.
  19. Remove chain tensioner.
