2023-2024 Jeep Compass Crank Gear Flange Dislocation TSB

Owners of certain 2023-2024 Jeep Compass and Jeep Meridian vehicles equipped with the 2.0L I4 Turbo Diesel Engine with ESS (Sales Code EBS) may experience issues related to a crank gear flange dislocation. This problem, identified as a manufacturing issue, is detailed in Technical Service Bulletin (TSB) 09-014-24, which was released on May 18, 2024. This TSB is also associated with Rapid Service Update (RSU) 24-090.

This bulletin applies to vehicles built on or after February 02, 2023 (MDH 0202XX) and on or before February 24, 2024 (MDH 0224XX). The TSB outlines a procedure for inspecting and potentially repairing the timing belt assembly to correct the crank gear flange dislocation.

Symptoms

Customers may notice one or more of the following symptoms if their vehicle is affected by the crank gear flange dislocation:

• "Vehicle does not start due to crank gear flanged dislocated."
• "Abnormal noise from the engine compartment."
• "Noise from the timing cover area."

These symptoms indicate a potential problem with the engine's timing system, specifically related to the crank gear flange dislocation.

Diagnosis and Trigger Conditions

To determine if a vehicle is subject to this service action, technicians must verify the VIN in the VIP system or check the RSU VIN list. The Rapid Service Update (RSU) 24-090 specifically applies only to vehicles on the RSU VIN list.

The diagnostic process involves inspecting the timing belt position. Technicians will rotate the engine and use a Vernier Caliper to measure the gap between the cam gear face and the belt face. If this gap is more than 3 mm (0.1 Inch), further action is required.

Repair Procedure Summary

The repair procedure outlined in TSB 09-014-24 involves a series of steps to address the crank gear flange dislocation. The primary goal is to inspect the timing belt position and, if necessary, replace the timing belt assembly.

1. Preparation: The air cleaner and fuel filter are removed to gain access to the engine components.
2. Timing Cover Access: The upper timing cover bolts are removed and discarded, followed by the removal of the upper timing belt cover. Technicians are specifically warned not to remove the timing belt immediately after removing the cover.
3. Bolt Adjustment: A mounting bolt is removed. The Puma bolt is loosened, and its spacer is then torqued to 11 N·m (97 In. Lbs.). The mounting bolt is reinstalled and torqued to 50 N·m (37 Ft. Lbs.).
4. Initial Inspection: The engine is rotated 360 degrees, and the belt position gap from the cam gear face to the belt face is measured using a Vernier Caliper. If the gap exceeds 3 mm (0.1 Inch), the timing belt is removed and reinstalled.
5. Re-inspection: After reinstallation, the engine is rotated 360 degrees again, and the belt position gap is rechecked. If the gap still exceeds 3 mm (0.1 Inch), technical support must be contacted for further instructions.
6. Reassembly: If the gap is within specifications, the timing cover is installed and its mounting bolts are torqued to 9 N·m (80 In. Lbs.). Finally, the fuel filter and air cleaner are reinstalled.
