C3940462 is available at the national depot (list $260, national depot
usually sends second day air), C3940461 is available at several regional
depots (list $108). Either parts kit has your oil pump, plus the other
stuff for whichever recall applies to your car.

NO.:499, 521 
March, 1992

To:All Dodge Dealers

Subject:Customer Satisfaction Notification # 499 -- Turbo III
Lubrication, PCV Hose and Crankshaft Timing Sprocket

Customer Satisfaction Notification # 521 -- Turbo III Lubrication

Models: # 499: 1991 Model Year Dodge Spirit RT (AA-Body)
Equipped With 2.2L DOHC Turbo III Engine -- Vehicles Built
From Job # 1 Through October 22, 1990

 # 521: 1991 Model Year Dodge Spirit RT (AA-Body) Equipped
 With 2.2L DOHC Turbo III Engine -- Vehicles Built From
 October 23, 1990 Through End Of Model Year

The engine oil pump drive gear on vehicles involved in
both Customer Satisfaction Notifications # 499 and # 521
may fail due to excessive stress on the gear teeth. To correct
the condition, a revised oil pump and intermediate shaft must be
installed in all vehicles. Also, the turbo oil drain-back hose
will be replaced, an insulator will be added to the hose, and a
new stone guard will be installed for the right (passenger side)
engine mount.

In addition, for the small number of vehicles in notification
# 499 only, 2 other conditions require correction:

The vehicles were built with an orifice in the PCV vacuum hose
which may allow water to enter and freeze in the hose, causing
positive crankcase pressure. A hose without an orifice must be installed.

The crankshaft timing sprocket may fail. This steel sprocket must
be replaced with a cast sprocket.

Some of the involved vehicles may still be in dealer stock. Be
sure to complete the service on these vehicles before retail delivery.

Details of this service action are explained in the following sections.

No videotape of the service procedure for this recall will be provided.

Important:  No parts will be distributed in advance for this service
requirement. Dealers must order as needed for vehicles to be repaired.

For service of involved vehicles, order the proper parts package for #
499 or # 521 as required. Package descriptions and components are as

(28 N-m) torque.

37. Reinstall the oil pan using the supplied gaskets. (Hold the gaskets
in place with RTV for ease of assembly). Tighten M6 bolts to 220
in.lbs. (25 N-m) and M8 bolts to 260 in.lbs. (29 N-m) torque.

38. Remove and discard the engine oil filter. Install a new Mopar

44. Reinstall the following parts:  - Shield at K-frame - Transmission
inspection cover - Driveshaft support bracket.1w

45. Lower the vehicle.

IMPORTANT:  Correct tensioning of the timing belt is critical to engine
performance and durability. Failure to follow the procedure specified
below will result in premature timing belt wear and possible engine

46. With the camshafts pinned and the crankshaft at TDC, install the
timing belt and idler pulley as shown in Figure 14 (note direction to
install belt).

47. With the camshaft pins still installed, install a belt tension
gauge on the timing belt (Figure 15).

Note:  The belt tension gauge must be installed between the belt teeth
to get an accurate reading.

Rotate the tensioner to adjust the belt tension to 70 pounds (311 N)
for used belts. If installing a new belt, the tension adjustment should
be 110 pounds (489 N).

48. Remove both camshaft pins, rotate the crankshaft clockwise 2 full
revolutions (back to the TDC mark) and check the alignment of both
camshaft sprockets to the cylinder head index holes by reinserting both
pins. Do not reverse rotate the crankshaft or attempt to rotate the
crankshaft using the cam or accessory shaft attaching screw.

CAUTION:  Do not allow oil or solvents to contact the timing belt as
they can deteriorate the rubber and cause tooth skipping.

49. Recheck the belt tension and repeat steps 47 and 48 as necessary to
obtain proper belt tension. Be certain to recheck the camshaft sprocket
alignment with each re-adjustment. When proper tension has been
obtained remove the camshaft pins and proceed to step 50.

50. Reinstall the accessory belt idler pulley bracket and tighten the
bolts to 40 ft.lbs. (54 N-m) torque.

51. Tighten the rocker arm shafts to 210 in.lbs.(24 N-m) torque in the
sequence shown in Figure 16.

52. Install the rocker cover and tighten the bolts to 115 in.lbs. (13
N-m) torque. Install the spark plugs and tighten them to 220 in.lbs (25
N-m) torque. Install the ignition cables and ignition cable cover.

53. For vehicles in notification # 499 only: Replace the PCV vacuum
hose with the supplied hose (Figure 17).

54. (All vehicles): Reposition the lower timing belt cover and install
the 2 lower screws. Tighten them to 105 in.lbs. (12 N-m) torque.

55. Install the upper timing belt cover and tighten the screws to 105
in.lbs.(12 N-m) torque.

56. Reinstall the right front engine mount (Fiqure 18) usinq the torque
values shown in the figure.

57. Install the PCV tube.

58. Install the air cleaner. Install the air cleaner hose clamp with
the screw on the top of the hose, so that it does not interfere with
the heat shield, (Figure 19). Tighten the clamp to 30 in.lbs. (4 N-m)

NOTE:  When installing the air cleaner, ensure that the oxygen sensor
wiring is routed and clipped between the heat shield and the air
cleaner, above the heat shield. Check that the oxygen sensor wiring
connector is oriented properly (Figure 20) and clipped to the heat
shield to prevent the harness from contacting the turbocharger housing
or exhaust manifold. Use the supplied clips to secure the wiring and
the wiring connector in the event that either is broken.

CAUTION:  The oxygen sensor wiring must be routed above the heat shield
and secured to prevent heat damage to the harness.

59. Ensure that the routing of the wiring at the right side shock tower
is correct. The clip should be in the upper hole (Figure 21). If only
one hole is present at the right side shock tower, drill a 1/4 inch
hole 1 inch above the existing hole and insert the wiring clip in the
upper hole.

60. Raise the vehicle.

61.Install the crankshaft pulley and tighten the bolts to 280 in.lbs
(31 N-m) torque, (Figure 22).

For vehicles in notification # 499 only: Use the 5 new bolts from the
parts package. (A damaged crankshaft timing sprocket could have damaged
the original bolts. The new, 5 mm longer bolts are required for this

62. Install the water pump pulley and tighten the bolts to 250 in.lbs
(28 N-m) torque, (Figure 22).

63. Install the idler pulley. Tighten the bolts to 40 ft.lbs (54 N-m)
torque, (Figure 22).

64. Install the accessory drive belt tensioner pulley. Start the bolt,
finger tighten it and then tighten it to 40 ft.lbs.(54 N-m) torque.

65. Install the accessory drive belt. (Figure 22).

NOTE:  The drive belt is provided with a dynamic tensioner to maintain
proper belt tension. No additional adjustment is required.

66. Install the right inner splash shield. Tighten 3 bolts to 24
in.lbs. (3 N-m) torque.

67. Install the right front tire and wheel assembly.

68. Lower the vehicle.

69. Fill with new engine oil to the proper level.

70. Reconnect the battery ground.

71. Start the engine and check for leaks.
